Second, we generated the two-vector-based “modular promoter” system, where one vector contains the mHSF1 under the control of the human CD83 promoter, which is specifically active only in DCs and after maturation. mHSF1, in turn, activates the Hsp70B′ core promotor-driven expression of transgenes MelanA and IL-12p70 in the DC-like cell line XS52 and in human mature and hence immunogenic DCs, but not in tolerogenic immature DCs. These in vitro experiments provide the basis for an in vivo targeting of mature DCs for the expression of multiple transgenes. Therefore, this modular promoter system represents a promising tool for future DC-based immunotherapies in vivo. To specifically target dendritic cells (DCs) to simultaneously express different therapeutic transgenes for inducing immune responses against tumors, we used a combined promoter system of adenoviral vectors. We selected a 216 bp short Hsp70B′ core promoter induced by a mutated, constitutively active heat shock factor (mHSF) 1 to drive strong gene expression of therapeutic transgenes MelanA, BclxL, and IL-12p70 in HeLa cells, as well as in mature DCs (mDCs). As this involves overexpressing mHSF1, we first evaluated the resulting effects on DCs regarding upregulation of heat shock proteins and maturation markers, toxicity, cytokine profile, and capacity to induce antigen-specific CD8 Thi70 genes . Third, + T cells in an antigen-specific manner whereas heat treatment of these DCs did result in the upregulation of maturation markers and increased capability to prime naïve CD8+ T cells [β, IL-6, IL-8, IL-12p70, and TNF-α in cell culture supernatants. We also found Hsp40 and Hsp70A to be upregulated in cell lysates of iDCs and mDCs, whereas Hsp70B′ and Hsp90 were only induced in mDCs. Heat shock proteins such as Hsp40 and Hsp70 have been described to act as chaperones and be involved in the proper folding of proteins as well as in the prevention of the formation of nascent protein aggregations thereby keeping the proteins in a substrate-grabbable state. Others, like Hsp90, have been demonstrated to contribute to antigen-presentation on MHC I [β, IL-6, IL-12, and TNF-α and to upregulate cell surface maturation markers CD83, CD86, or CD40 as well as to enhance the migratory capacity of DCs [Interestingly, overexpression of mHSF1 did not influence the maturation status, the survival of immature and mature DCs, or their capability to prime naïve CD8 T cells .

To perform first proof of principle, we successfully expressed several therapeutic transgenes under the control of the core Hsp70B′ promoter element, which we could specifically induce with CMV promoter-driven mHSF1 both in HeLa cells by plasmid transfection and in primary mature human DCs by adenoviral vectors . In a seNK cells . Moreovel trials . Of note DC-STAMP gene as a suitable promoter region to yield long-term and cell-selective transgene expression in murine DCs in vivo [ in vitro and in vivo; however here we report the first promoter system allowing the specific targeting of mature human DCs. Regarding its future prospects for cancer therapy, the CD83-Hsp70B′ promoter system offers several interesting features. Due to its modular composition, the system is highly flexible and hence not restricted to a specific tumor entity or therapeutic application. On the one hand, the therapeutic transgenes encoded by one adenoviral vector could be replaced by any gene of interest, even mutated cancer- and patient-specific TAAs. On the other hand, it would be possible to use an even more specific promoter or one with different cell-specificity, for the expression of the mHSF1 within the other vector. This modular composition would in theory allow the in vivo targeting of any combination of transgenes to any cell type although this requires substantial additional preparatory experiments. Moreover, by combining transductional targeting of adenoviruses to dendritic cells via bispecific diabodies or single-chain antibodies incorporated into the virus capsid, a further increase of targeting specificity might be achieved.To date, only very few promoter systems have been proven suitable for the transcriptional targeting of DCs. The group of Ross et al., for instance, demonstrated the promoter of the cytoskeletal fascin protein to induce specific transgene expression in mature murine DCs after gene gun-mediated DNA immunization . Similar in vivo . Several in vivo and could set the stage for next generation in situ vaccination strategies. This should be particularly effective and safe, as it assures selective antigen expression in mDCs while avoiding expression in tolerogenic iDCs for the first time. These promising perspectives, however, need to first be analyzed and explored in further preclinical investigations.Finally, since CD83 is not expressed by immature but is highly induced in mature DCs, the applied CD83 promoter complex represents an ideal candidate for transcriptional targeting of mature DCs in vitro experiments showing that a combined two-vector CD83-Hsp70B′ promoter system is able to transcriptionally target human mature DCs for the first time with a highly specific and effective expression of a panel of potential therapeutic transgenes. Moreover, we first demonstrate that overexpression of mHSF1 does not interfere with DC maturation, viability, and function. Hence, this study provides valuable new insights for the development of a safe, modular, highly flexible, and hence patient-tailored vaccination protocol for in vivo targeting of DCs, but also other efficient genetic therapies in the future.In this study, we present the initial


EK activity is stimulated by carcinogens and oncogenes, suggesting the involvement of EK in carcinogenesis. Currently, little is known about EK transcriptional regulation by endogenous or exogenous signals, and the ek gene promoter has never been studied.Ethanolamine kinase (EK) catalyzes the phosphorylation of ethanolamine, the first step in the CDP-ethanolamine pathway for the biosynthesis of phosphatidylethanolamine (PE). Human EK exists as EK1, EK2α and EK2β isoforms, encoded by two separate genes, named ek1 promoter. 5’ deletion analysis and site-directed mutagenesis identified a Sp site at position (-40/-31) that was essential for the basal transcription of this gene. Treatment of HCT116 cells with trichostatin A (TSA), a histone deacetylase inhibitor, significantly upregulated the ek1 promoter activity through the Sp(-40/-31) site and increased the endogenous expression of ek1. Chromatin immunoprecipitation assay revealed that TSA increased the binding of Sp1, Sp3 and RNA polymerase II to the ek1 promoter in HCT116 cells. The effect of TSA on ek1 promoter activity was cell-line specific as TSA treatment did not affect ek1 promoter activity in HepG2 cells.In this report, we mapped the important regulatory regions in the human ek1 gene, their accessibility to the target site on the ek1 promoter is regulated by histone protein modification in a cell line dependent manner.In conclusion, we showed that Sp1 and Sp3 are not only essential for the basal transcription of the  While ek1 codes for a single protein, EK1 (452 amino acids), ek2 undergoes alternative splicing to produce two other EK isoforms, EK2α (386 amino acids) and EK2β (394 amino acids) , human colon carcinoma HCT116 [ATCC No: CCL-247] and human breast adenocarcinoma MCF-7 [ATCC No. HTB-22] cell lines were cultured in high glucose Dulbecco’s modified Eagle’s medium (DMEM) supplemented with 10% (v/v) heat inactivated fetal bovine serum (FBS), 100 U/mL penicillin and 100 μg/mL streptomycin. Cells were incubated at 37°C in a COek1 promoter fragment -1966/+1 was amplified by PCR from human genomic DNA  using forward primer (ek1-1966-5’) and reverse primer (ek1-3’) incorporating NheI and BglII sites, respectively. PCR product was cloned in frame at the 5’-end of XhoI/HindIII site of the promoterless firefly luciferase reporter vector pGL4.10[luc2] , yielding pGL4.10-ek1(-1966/+1). The 5’-end deletion constructs of pGL4.10-ek1(-1183/+1) and pGL4.10-ek1(-665/+1) were made by restriction digestion of pGL4.10-ek1(-1966/+1) with SacI/XmaI and KpnI, respectively. pGL4.10-ek1(-229/+1) was prepared by inserting the HindIII digested fragment from the pGL4.10-ek1(-1966/+1) into the dephosphorylated HindIII digested pGL4.10[luc2] vector. pGL4.10-ek1(-154/+1), pGL4.10-ek1(-100/+1) and pGL4.10-ek1(-69/+1) deletion constructs were generated by PCR using pGL4.10-ek1(-1966/+1) as the template. The PCR products were subcloned into the XhoI/HindIII site of pGL4.10[luc2] vector. Mutations of Sp binding sites were introduced into pGL4.10-ek1(-69/+1) by PCR to produce pGL4.10-ek1-mut[Sp(-69/-60)], pGL4.10-ek1-mut[Sp(-40/-31)] and pGL4.10-ek1-mut[Sp1(-69/-60)/(-40/-31)]. The primers used in this study are listed in The 5 cells/well for 24 hr. The cells in each well were co-transfected with 200 ng of promoter reporter constructs or pGL4.10[luc2] and 2.5 ng of pGL4.73[hRluc/SV40] vector (Promega) All firefly luciferase activities were normalized to (divided by) Renilla luciferase activity in the same sample to control for differences in transfection efficiency. Forty-eight hours after transfection, cells were harvested and assayed using Dual-Glo Luciferase Reporter Assay System (Promega). The luminescent signals were measured by GloMax® 20/20 Luminometer . Each of the luciferase assays was performed in triplicate of three independent experiments.Promoter reporter constructs were transiently transfected into mammalian cancer cells using Lipofectamine 2000 (Invitrogen) according to the manufacturer’s instruction. Briefly, cells were plated in 100 μL of medium/well on a 96-well plate at a density of 1.5 × 10ek1 promoter activity was determined by treatment of pGL4.10-ek1(-69/+1) and pGL4.73[hRluc/SV40] co-transfected HCT116 or HepG2 cells with varying concentrations of TSA  for 24 hours. The effect of TSA treatment duration was studied by treatment with 1.0 μM of TSA for 6, 12 and 24 hours. DMSO was added to the cells instead of TSA for negative controls. After treatment, the cells were harvested and assayed by Dual-Glo luciferase assay.The effect of trichostatin A (TSA) on ™ H Minus First Strand cDNA Synthesis kit . The mRNA level of ek1 gene was measured by quantitative real-time PCR (qPCR) performed on an ABI PRISM 7000 Sequence Detection System . The intron-spanning ek1 primers are listed in ek1 was determined in this study by first generating a standard curve from serial dilution of cDNA template followed by calculation according to this formula: PCR amplification efficiency (%) = (10−1/slope−1) × 100%  produced in the initial round of 5’-deletion analysis. Deletion of the 5’ sequence from the parental promoter construct until the -1182 position resulted in a dramatic decrease of the promoter activity to approximately 11% of the full-length promoter construct. The results suggested that there was at least one positive regulatory element located inside the region between -1966 and -1183. Further deletion of the 5’ end sequence from -1183 to -665 recovered the activity to about 70% of the full length promoter, indicating the presence of at least one inhibitory element in this region (between -1183 and -665). Truncation of the region between -665 to -229 did not cause any significant change of promoter activity. The region downstream of the -229 position was further truncated to map the minimal promoter region for initiating ek1 gene transcription. As shown in ek1 promoter from -229 to -154 increased its activity by more than seven times compared to the -229 promoter construct, indicating the presence of at least one repressive element in this region. Subsequent truncations (-100 and -69 promoter constructs) did not show any dramatic change of promoter activity. Thus, the reporter construct containing the -69/+1 ek1 promoter fragment was taken as the minimal promoter region for conferring basal transcription activity of ek1gene.The activities of various 5’-deletion constructs of ek1 basal promoter region revealed two putative Sp and one CREB binding sites at positions -69/-60, -40/-31, and -27/-19, respectively. The importance of the two putative Sp binding sites in regulating the ek1 transcription was examined by single or double mutations of the Sp sites in the pGL4.10-ek1(-69/+1) reporter construct. As shown in ek1 promoter activity.Bioinformatics prediction of transcription factor binding sites in the -69/+1 ek1 promoter and the Sp(-40/-31) site was required for this effect to take place. Since serum starvation could affect genes expression through the modulation of chromatin modification  promoter constructs were transfected into HCT116 cells and treated with 1 μM TSA for 24 hours. As shown in ek1 promoter activation. This result shows that the Sp(-40/-31) site is essential for the activation of ek1 gene transcription by TSA.To further confirm the involvement of the Sp(-40/-31) site in the TSA-mediated upregulation of ek1 gene, the ek1 mRNA level in the cells treated or untreated with TSA was determined by real-time PCR. All the RNA samples used for cDNA synthesis were intact and pure as indicated by the prominent 28S and 18S ribosomal RNA bands and the ratios of OD260/280 from 1.8 to 2.0. The PCR efficiency of ek1 primers was 89%. Based on the data from triplicate samples from three independent experiments, exposure of HCT116 cells to 1 μM of TSA for 24 hours resulted in moderate but significant increase of ek1 gene expression by about 0.5 fold compared with the DMSO treated control cells  response element. The result showed in ek1 minimal promoter as compared to control.Subsequently, the effect of TSA treatment on the binding of Sp proteins to the Sp(-40/-31) site of cificity . The ek1ek1 promoter was also examined by using ChIP assay. As shown in ek1 promoter activity and endogenous expression by TSA treatment is resulted from the changes in the chromatin structure around the Sp(-40/-31) site that consequently increased the local recruitment of Sp1/Sp3 transcription factors and RNA polymerase II to the ek1 minimal promoter region.The inhibition of HDACs activities by TSA treatment has also been reported to enhance the recruitment of RNA polymerase II to certain promoters –29. Theret al [ek1 mRNA transcripts were detected in kidney, liver, heart, leukocytes, small intestine and ovary compared to the levels in colon, skeletal muscle and prostate. This suggests that ek1 promoter might be regulated differently according to cell type. To investigate whether the TSA activation of ek1 promoter was cell-line specific, the effect of TSA treatment on ek1 promoter activity was studied in liver cancer cell line, HepG2. As shown in ek1 promoter activity as in the case of HCT116 cells.According to Lykidis et al , higher ek1 minimal promoter region in HCT116 and HepG2 cells without any treatment was carried out. ek1 promoter without TSA treatment and this explained why the promoter activity was not affected by TSA as in the case of HCT116 cells.In order to answer the question of whether the binding of Sp transcription factors was also cell-line specific, ChIP analysis for the binding of Sp1 and Sp3 to the ek1 promoter and investigate the possibility of ek1 gene transcription regulation by epigenetic mechanism. Based on our sequence analysis, the ek1 gene promoter is a TATA-less, GC-rich promoter which probably belongs to the housekeeping gene family. This assumption is supported by the fact that approximately 76% of human TATA-less core promoters contain multiple Sp1 binding elements in the GC rich sequences [In this work, we aimed to characterize the equences  and the equences , 32.ek1 promoter (-1966/+1) was initially assessed in HepG2, HCT116 and MCF-7 cells. Under the same transfection conditions, the luciferase expression level driven by the ek1 promoter varied with the cell line used. The transcription level of luc2 reporter gene in the transfected promoter-luciferase reporter construct generally depends on the level of required transcription factors in the host cell. The levels of certain transcription factors are cell line dependent such as the expression level of Ets-1 in MCF-7 cell is known to be 10% lower than the other cell lines [ek1 promoter activities in the three cell lines tested might be due to different expression levels of the required transcription factors.The activity of putative ll lines . Therefoek1 gene promoter basal activity. This region is CpG rich, with two putative binding sites for Sp proteins. However, only one of the Sp binding sites located at -40/-31 is critical as the positive regulatory element for ek1 gene transcription. Sp1 and Sp3 are two closely related members of Sp-family transcription factors based on their similarities in structure and binding specificity to GC or GT motif [ek1 promoter is a TATA-less promoter, the binding of Sp1 to Sp(-40/-31) site in the promoter is pivotal to the transcription initiation of ek1 gene. Mutation introduced at this site completely abolished the ek1 promoter activity possibly due to the disruption of PIC formation on ek1 promoter.Deletion analysis revealed that the region spanning from -69 to +1 is critical for the GT motif , 35. TheGT motif –39. Sp1 GT motif . Sp1 plaGT motif . Since eek1 gene transcription was studied using HDAC inhibitor TSA. It was found that treatment of HCT116 cells with TSA caused a potent stimulation of ek1 promoter activity. In addition, we showed that the Sp(-40/-31) site located in the GpG-enriched region of ek1 promoter was not only essential for ek1 basal promoter activity but also was important for TSA response. Previous studies have pointed to Sp1 and Sp3 transcription factors as the mediators of HDAC inhibition in the regulation of gene transcription [ek1 mRNA level induced by TSA is markedly lower than the TSA-mediated upregulation of ek1 promoter activity. One possible explanation for the discrepancy between ek1 mRNA level and its promoter activity is the involvement of other regulatory region in ek1 promoter or post-transcriptional regulation of ek1 gene expression.Histone acetylation/deacetylation is mainly regulated by histone acetyltransferases (HATs) and histone deacetylases (HDACs) . HATs accription , 40, 41.GGGGCGGGC) or GT (GGGTGTGGC) motifs [ek1 promoter. We suggest that the activation of ek1 promoter by HDAC inhibitor requires the binding of Sp1 or Sp3 to the ek1 minimal promoter region. Previous study has shown that TSA could induce the recruitment of RNA polymerase II to the transcription factor complex for the initiation of transcription process [ek1 transcription. Our results indicate that the activity of ek1 minimal promoter region harboring the Sp(40/-31) site is significantly affected by histone modifications. HDACs play an important role in carcinogenesis by regulating the expression of genes involved in both cancer initiation and progression [ek1 gene expression that affects cell survival.Sp-family of transcription factors consists of four proteins designated Sp1, Sp2, Sp3 and Sp4 which are involved in the expression of a large number of housekeeping genes .

We showed that, unlike in HCT116, the binding of Sp1 and Sp3 to ek1 basal promoter region had already occurred in HepG2 cells before TSA treatment. The cell-type specificity of TSA effect could be due to differential regulation of ek1 gene in different cell types as evidenced by variable level of ek1 mRNA transcript across multiple tissues [ek1 promoter was also supported by the results in this study that showed ek1 promoter (-1966/+1) activity was clearly different among the three cell lines used.It is worth noting that TSA up-regulation of ek1 basal promoter. The transcriptional regulation of ek1 is associated with chromatin remodeling and Sp1/Sp3/RNA polymerase II accessibility to promoter region around the Sp(-40/-31) site. Sp1 and Sp3 not only function in concert with the basal transcriptional machinery to initiate ek1 gene transcription, their accessibility to the target site on ek1 promoter also depends on histone proteins modification. This study delineates the essential cis-acting regulatory element of ek1 promoter and its possible modulation by chromatin structure modification that is useful for the fundamental understanding of ek1 gene transcriptional regulation.In conclusion, this study showed that Sp(-40/-31) site is required for the transcriptional activation of the


In order to understand better the relationship between developmentally regulated chromatin landscapes and regulation of early B cell development, we determined how differentially active promoter regions were able to predict relative RNA and protein levels at the pre-pro-B and pro-B stages. Herein, we describe a novel ChIP-seq quantification method (cRPKM) to identify active promoters and a multi-omics approach that compares promoter chromatin status with ongoing active transcription (GRO-seq), steady state mRNA (RNA-seq), inferred mRNA stability, and relative proteome abundance measurements (iTRAQ). We demonstrate that active chromatin modifications at promoters are good indicators of transcription and steady state mRNA levels. Moreover, we found that promoters with active chromatin modifications exclusively in one of these cell states frequently predicted the differential abundance of proteins. However, we found that many genes whose promoters have non-differential but active chromatin modifications also displayed changes in abundance of their cognate proteins. As expected, this large class of developmentally and differentially regulated proteins that was uncoupled from chromatin status used mostly post-transcriptional mechanisms. Strikingly, the most differentially abundant protein in our B-cell development system, 2410004B18Rik, was regulated by a post-transcriptional mechanism, which further analyses indicated was mediated by a micro-RNA. These data highlight how this integrated multi-omics data set can be a useful resource in uncovering regulatory mechanisms. This data can be accessed at:  E2a and Ebf1 both function to activate transcription of several early B lineage genes  to a committed B lineage cell (pro-B) (Published work suggests that B lymphocytes develop from lymphoid-primed multi-potent progenitors (LMPPs) in the bone marrow that also give rise to myeloid progeny such as macrophages and granulocytes ,4.

We postulated that by using a defined promoter region for each gene and not requiring a ‘peak’ to have a particular shape, this approach would not suffer from some of the issues we encountered when using MACS to identify promoters enriched in these active chromatin modifications. We identified promoters as within 200 bp (+/−200 bp) of the transcription start site (TSS) of all protein-coding RefSeq genes and then counted the number of reads for H3K4me3 and H3ac in the ChIP-seq data that overlap these regions. Summing the values for both active chromatin modifications provides what we are calling the cumulative ChIP RPKM , a cumulative index of predicted promoter activity. Its cumulative nature should improve analyses since we need to overcome sequencing depth issues as we note that the sequencing depths of the previously published H3K4me3 and H3ac ChIP-seq libraries were 70% lower and 17% lower, respectively, in pre-pro-B cells than in pro-B cells (library depth can be found in P) in both pre-pro-B and pro-B cells, and compared that to the distribution of cRPKM values for corresponding regions 2 kb upstream (cRPKMU) and for randomly generated 400 bp genomic intervals (cRPKMR)  .

In fact, we find that while approximately one quarter of the genes with predicted ‘inactive in both’ promoters had an RPKM of zero  and ‘active in both’  predicted promoter classes are substantially higher than the exclusively active classes , so the sum of the distribution of the GRO-seq values for ‘inactive in both’ and ‘active in both’ predicted promoter classes represents the general distribution of GRO-seq values. Given this, we note that the distribution of GRO-seq values form two quite distinct populations, one that is transcribed two to three orders of magnitude lower than the other and that our cRPKMSatB1), AT-rich interactive domain 3a (Arid3a), Foxo1, homeobox protein A3 (Hoxa3), and runt-related transcription factor 2 (Runx2), all factors implicated in hematopoiesis, are in this group, but show different levels of ongoing transcription , the ‘exclusively pre-pro-B’ and ‘exclusively pro-B’ predicted promoter classes segregate, demonstrating that a large fraction of genes in these classes exhibit differential ongoing transcription levels  was assigned to each protein-coding RefSeq gene for each cell type, and differential expression was determined using Cuffdiff2.1.1 [10(FPKMpro-B/ FPKMpre-pro-B)] ] .

As indicated above, numerous genes also displayed differential ongoing transcription (GRO-seq), thus there are likely co-transcriptional and post-transcriptional means of regulating mRNA levels . In the exclusively active classes, by filtering the RNA-seq data with predicted promoter status, we are able to identify and enrich for genes that are likely mostly transcriptionally regulated in a specific developmental program . Examples of known B cell development regulatory genes that are included in this group are Pou2af1, Aiolos (Ikzf3), and Irf4 that are upregulated in pro-B cells, while Cd34 and Flt3 are upregulated in pre-pro-B cells, most of which were also identified as displaying differential ongoing transcription (GRO-seq)  on the Y axis and differential ongoing transcription [log2(RPKMpro-B/RPKMpre-pro-B)] on the X axis, color-coding these data for the two cell types (Dnmt3a) and cyclic AMP responsive element binding protein 1 (Creb1)]  ,41. Theslity see .Since we observed that certain populations of genes could have such dramatic cell type specific differential between steady state mRNA levels and ongoing transcription levels, we explored the global relationship between our predicted promoter classes and mRNA stability—specifically asking if promoter status may somehow be linked to this type of post-transcriptional regulation. By taking the ratio of FPKM (steady state mRNA) and RPKM (ongoing transcription) values for all protein-coding RefSeq genes, we generated an inferred measure of stability for each transcript. While the frequency distributions of these calculated ratios for the two exclusively active predicted promoter class appears quite similar in both cellular state , and wheIkzf3 (Aiolos), Pou2af and Irf4 , genes previously shown to be up-regulated in pro-B cells, are in our ‘exclusively pro-B’ predicted promoter class and are up-regulated in our proteome data  . The largest number of iTRAQ identified proteins come from genes with unchanging predicted promoter classes, almost all of these are from the predicted ‘active in both’ promoter class . However, a few are from the predicted ‘inactive in both’ class (189 proteins); they could derive from gene products with TSSs that are not annotated, genes that are only active in a very small fraction of the cells or for a very small fraction of the time but give protein products that yield peptides that are favored for detection by our LC-MS/MS strategy, or from genes with mis-classified promoters. As expected, the vast majority of the proteins encoded by the genes in the ‘active in both’ and ‘inactive in both’ classes do not have significant differential abundance values . This isproteins .We further considered the inter-relationships between predicted promoter classes and differential transcription, transcript steady state, and protein levels. For these mutli-omics differential analyses, there are 27 possible regulatory combinations of differential abundance at the ongoing transcription, steady state mRNA, and protein levels. Defining differential abundance as a change of at least 2-fold, 2-fold, and 1.5-fold, respectively, Galnt11 is of particular interest, as it has recently been shown to be up-regulated in chronic lymphocytic leukemia (CLL) and associated with poor disease prognosis .–50.in sik 3’ UTR  52].

AMH is an ovarian target gene of steroidogenic factor-1 (SF-1), an orphan nuclear receptor required for proper follicle development. FOXL2 is an evolutionally conserved transcription factor, and its mutations cause blepharophimosis, ptosis, and epicanthus inversus syndrome (BPES), wherein affected females display eyelid defects and premature ovarian failure (POF). Notably, we found that functional FOXL2 is essential for SF-1-induced AMH regulation, via protein–protein interactions between FOXL2 and SF-1. A BPES-inducing mutant of FOXL2 (290–291delCA) was unable to interact with SF-1 and failed to mediate the association between SF-1 and the AMH promoter. Therefore, this study identified a novel regulatory circuit for ovarian AMH production; specifically, through the coordinated interplay between FOXL2 and SF-1 that could control ovarian follicle development.Anti-Müllerian hormone (AMH) is required for proper sexual differentiation by regulating the regression of the Müllerian ducts in males. Recent studies indicate that AMH could be an important factor for maintaining the ovarian reserve. However, the mechanisms of AMH regulation in the ovary are largely unknown.

IPT3 and IPT7) and one cell cycle inhibitor (KRP7). Our results demonstrate that SWI/SNF complexes containing BAF60 are key factors governing the equilibrium between formation and dissociation of a chromatin loop controlling phytohormone production and cell cycle progression.Chromatin architecture determines transcriptional accessibility to DNA and consequently gene expression levels in response to developmental and environmental stimuli. Recently, chromatin remodelers such as SWI/SNF complexes have been recognized as key regulators of chromatin architecture. To gain insight into the function of these complexes during root development, we have analyzed Arabidopsis knock-down lines for one sub-unit of SWI/SNF complexes: BAF60. Here, we show that BAF60 is a positive regulator of root development and cell cycle progression in the root meristem via its ability to down-regulate cytokinin production. By opposing both the deposition of active histone marks and the formation of a chromatin regulatory loop, BAF60 negatively regulates two crucial target genes for cytokinin biosynthesis ( They participate in virtually all aspects of plant development and physiology including the shoot and root meristems, leaf senescence and responses to environmental cues ).Ai lines .

AltogetKRP7 loop was about 3 times more present in the BAF60 RNAi context  [IPT genes.Even though the molecular mechanisms underlying the function of CK during root development are beginning to be well described, the transcriptional mechanisms that control CK production remain very poorly understood. The HD-ZIPIII transcription factor PHABULOSA (PHB) is the only known transcriptional regulator of genes involved in CK biogenesis. In fact PHB was shown to directly activate the CK biosynthesis gene 7 (IPT7) , thus prIPT3 and IPT7 are over-expressed in BAF60-RNAi lines and BAF60 binds directly to these loci. A connection between SWI/SNF complexes and CK signaling was recently uncovered [ARR16 gene, an A-class ARR factor that inhibits CK signaling. In fact, brm mutants were shown to be over-sensitive to CK, consistent with its action on negative regulators of CK signaling. However, they did not test if the over-sensitivity of brm to CK could not at least partly be due to changes in CK accumulation or biosynthesis. Because BAF60 and BRM can be part of the same protein complexes [Indeed, ncovered  but nothKRP7 gene encoding a CDK inhibitor to regulate its expression, thus providing evidence for an additional layer of regulatory complexity. The consecutive over-expression of KRP7 in BAF60 RNAi lines could account for the increase in the number of G1 cells. Indeed, high levels of ICK/KRP proteins have been shown to inhibit the G1-to-S phase transition of both mitotic and endocycling cells [KRP7 expression [KRP7 mis-regulation in BAF60 RNAi lines: is it due to the over accumulation of CK or to a direct effect of BAF60 on this locus? From our data and the available literature the answer is probably both. On one hand, exogenous CK is sufficient to induce over-accumulation of the KRP7 transcript [KRP7 locus to control its transcriptional status through modulation of its chromatin structure and the deposition of RNA polymerase II and specific histone marks. Altogether these data suggested that both CK and BAF60 regulate the expression of KRP7, linking chromatin remodelers to CK signaling and cell cycle regulation. In Arabidopsis, a connection between chromatin organization and auxin has been recently described [PID locus to regulate its transcription. Reciprocally, here we show that changes in chromatin structure can in turn regulate hormone production. Although available data concerns only a few genes, it is likely that these findings can be generalized to many loci, and that more global analyses of BAF60 targets will provide evidence for a complex interplay between hormone signaling and chromatin organization. Hormones may modulate chromatin structure, while chromatin structure can also modulate hormone levels in planta.In the root meristem, the balance between auxin and CK signaling controls the transition from cell proliferation to differentiation, with auxin stimulating division and preventing elongation and CK having an opposing function ,20, and ng cells . Interespression , raisinganscript . On the escribed : it was IPT3, IPT7 and KRP7 transcription by modulating chromatin structure at these loci. Genome topology has emerged as a key player in genome functions. In eukaryotes, gene expression is influenced by the interactions between transcription factors and the DNA, which can adopt diverse 3D chromatin structural conformations [FLC locus. At this specific locus, we showed that BAF60 interacts with the 5’ and the 3’ part of the FLC locus [FLC by negatively affecting the loop dynamics through the modulation of histone density, composition and post-translational modification. Similarly here we report modifications of the chromatin status of IPT and KRP7 genes. Altogether, these data suggest that BAF60 is a general regulator of transcription through its ability to modulate gene loop structure, histone marks and RNA pol II deposition. One crucial question is the sequence of events that leads to these changes in chromatin organization: do modifications of histone marks allow gene loop formation and release, or does gene looping influence histone mark deposition? In yeast and mammals, certain repressive SWI/SNF-related complexes were shown to possess histone deacetylase activity, known to repress transcription, suggesting that nucleosome-remodelling activities could be coupled with chromatin modifying activities to promote transcriptional repression [From a molecular point of view, we showed that BAF60 could directly repress rmations .

The regulation of gene expression in eukaryotic cells is a complex process that involves epigenetic modifications and the interaction of DNA with multiple transcription factors. This process can be studied with unprecedented sensitivity using a combination of chromatin immunoprecipitation and next-generation DNA sequencing (ChIP-seq). Available ChIP-seq data can be further utilized to interpret new gene expression profiling experiments.Here, we describe seqinspector, a tool that accepts any set of genomic coordinates from ChIP-seq or RNA-seq studies to identify shared transcriptional regulators. The presented web resource includes a large collection of publicly available ChIP-seq and RNA-seq experiments (>1300 tracks) performed on transcription factors, histone modifications, RNA polymerases, enhancers and insulators in humans and mice. Over-representation is calculated based on the coverage computed directly from indexed files storing ChIP-seq data (bigwig). Therefore, seqinspector is not limited to pre-computed sets of gene promoters.http://seqinspector.cremag.org.The tool can be used to identify common gene expression regulators for sets of co-expressed transcripts  or for sets of ChIP-seq peaks to identify putative protein-protein interactions or transcriptional co-factors. The tool is available at The online version of this article (doi:10.1186/s12859-016-0938-4) contains supplementary material, which is available to authorized users. The regulation of gene expression is one of the most complex processes in living organisms . This prHere, we present seqinspector, a bioinformatics service that utilizes up-to-date ChIP-seq data. Our tool allows the functional enrichment of user-defined lists of genes, transcripts and ChIP-seq peaks. The user is not limited to a predefined set of promoter regions and can use any set of genomic coordinates. Our tool provides solutions for multiple challenges that have arisen with new sequencing technologies. The first difficulty encountered in interpreting RNA-seq experimental results is that the output encodes multiple novel noncoding or un-annotated transcripts that are not represented in current databases. Another challenge that is often faced is the compatibility of the tool with dynamic and continuously updated genome annotations. Additionally, the tool should provide users the opportunity to search for protein binding sites in regions outside of gene promoters. For example, users might want to search for specific proteins that bind to the introns of differentially spliced genes or analyze peak regions obtained from new ChIP-seq experiments. Therefore, we eschewed the standard approach that uses gene annotations directly or converts genomic coordinates to gene annotations. Instead, our tool converts gene annotations into genomic ranges. For this purpose, we developed a new strategy for data storage, raw genomic bigwig tracks instead of an SQL system. These tracks are analyzed every time the user inputs a query. This method allowed us to develop a new coverage-based approach to calculate enrichment statistics.Next-generation sequencing generates vast amounts of data. The results are typically presented as signal information (a per-base estimate across the genome) and as discrete elements . The most useful file formats for storing ChIP-seq experimental results are bigwig and bigbed for signal information and discrete elements (peaks), respectively . Both fot-test to compare the ChIP-seq track coverages derived from two samples of genomic ranges that were provided by the user and the background set. By default, the background set consists of 1000 random gene promoters and can be replaced by the user-defined set. A statistic based on the parametric z-score is used for a single-gene exploration.The decision to choose a storage method between raw coverage (bigwig files) and peaks derived from ChIP-seq data (bigbed files) was critical to further implementing the system. Despite being computationally challenging, raw coverage files were favored because they can be directly used in visual explorations. Therefore, we used raw coverage files to store the data. This process required a different statistical approach than commonly implemented in over-representation analyses that assume a hypergeometric data distribution –10. We dMus musculus mm9 and mm10 and Homo sapiens hg19) and the query input ; (6) Bonferroni—Bonferroni-corrected P-value; (7) Stack plot—stacked plots presenting the distribution of coverages in all query sets with respective p-values; (8) Histogram– a visualization of the average coverage  for all query sets; (9) Genes—genomic intervals in the query set, symbols for nearest genes and coverage for these intervals; and (10) Description—description of the track.Based on previous experience with developing user interfaces for bioinformatics resources , 12, we put Fig. .

We submitted the top 358 peaks  from this dataset to seqinterpreter as genomic ranges in bed format , (2) SP2 (P = 1.7 × 10-33), (3) NFYA (P = 8.9 × 10-47), (4) NFYB (P = 9.6 × 10-41), (5) E2F4 (P = 1.8 × 10-16), (6) IRF1 (P = 2.2 × 10-7) and (7) SRF (P = 1.2 × 10-6). The tool identified also other transcription factors binding to the same sites, including IRF3 (P = 3.0 × 10-43), C-FOS (P = 4.0 × 10-42) and CHD2 (P = 6.8 × 10-41). All of the presented P-values are Bonferroni corrected.seqinterpreter can be applied to study protein-protein interactions. seqinterpreter calculates the average coverage for all stored ChIP-seq tracks for the submitted genomic ranges. The obtained coverages are then compared with a reference dataset using a two-sample ng sites . seqinspP = 0.0034). For neuron-specific genes, 14 over-represented tracks were noted, including 13 FANTOM5 tracks generated from neural tissue or isolated neurons  and one ENCODE track for the neuron-restrictive silencer factor .Another straightforward application of seqinspector is the study of transcript expression in various tissue and cell types. For this purpose, tracks generated by the FANTOM5 project using cap analysis of gene expression were added to the seqinspector database . This type of analysis reveals active transcription start sites and gene variants expressed in particular cell populations. List of genes or transcripts derived from microarray or RNA-seq profiling experiments can be inspected for cell-type-specific gene expression. To provide an example of this utility, we used results of gene expression profiles in different cellular compartments of the nervous system .

For thSSUM 3.0  to meet in silico approaches to predict transcription factor binding sites were limited to those specific regions [in silico-computed transcription factor binding sites. Another advantage of ChIP-seq–based enrichment services is the ability to search for distant enhancer transcription factors through indirect binding to promoter regions. Enhancer regions can be distant (even up to 200 kb) from the proximal promoter of a target gene [Comparative genomic studies suggest that 3 to 8 % of the sequence information in a genome is evolutionarily conserved among mammals . Earlier regions . Howeverget gene . To demoA unique feature of seqinspector is that it accepts any set of genomic coordinates. Therefore, the tool can be used to identify common gene expression regulators for sets of co-expressed transcripts  or for sets of ChIP-seq peaks to identify putative protein-protein interactions or transcriptional co-factors. Our software enables the study of transcript expression in various tissues and cell types using FANTOM5 CAGE data. Therefore, it is possible to identify the enrichment of cell-type-specific genes or transcripts. The seqinspector software package can also be used in more creative ways; for example, the user can compare the characteristics of 5’ untranslated region (UTR) histone modifications between two sets of transcripts. We are continuously adding new ChIP-seq experiments to the database. seqinspector is not easily outdated; any novel genomic features  can be used if their genomic positions are known. Even after major assembly changes in databases, the new genomic ranges can be translated to the old versions of the genome assembly using the liftover tool. This mechanism is currently built into seqinspector for the mouse mm10 assembly.The seqinspector tool was developed to facilitate the functional annotation and discovery of transcription factor binding sites on promoters of co-expressed transcripts, signals from ChIP-seq experiments and any other set of genomic coordinates sharing a common trait.

This review is to explore whether potential gene interactions in the cell cycles of gametes, zygotes, and embryonic stem (ES) cells are associated with the development of cancer.MEDPILOT at the Central Library of the University of Cologne, Germany  that covers 5,800 international medical journals and 4,300 E-journals was used to collect data. The initial searches were done in December 2012 and additional searches in October 2013–May 2015. The search terms included “cancer development,” “gene interaction,” and “ES cells,” and the time period was between 1998 and 2015. A total of 147 articles in English language only were included in this review.de novo gene synthesis and neofunctionalization. Post-translationally, mutated genes are preserved in pre-neoplastic ES cell subpopulations that can give rise to overt cancer stem cells. Thus, TFs operate as cell/disease-specific epigenetic messengers triggering clinical expression of neoplasms.Transgenerational gene translation is implemented in the zygote through interactions of epigenetic isoforms of transcription factors (TFs) from parental gametes, predominantly during the first two zygote cleavages. Pluripotent transcription factors may provide interacting links with mutated genes during zygote-to-ES cell switches. Translation of post-transcriptional carcinogenic genes is implemented by abnormally spliced, tumor-specific isoforms of gene-encoded mRNA/non-coding RNA variants of TFs employing Potential gene interactions in the cell cycle of gametes, zygotes, and ES cells may play some roles in the development of cancer. DNA-encoded gene replication is usually stable but not permanent during meiotic and mitotic cell cycles. Indeed, the genome can be interpreted as an evolutionary organ of epigenetic gene transcription/translation; its complex gene replication patterns affect normal, as well as neoplastic cells , 2. The Mutagenic and carcinogenic properties of somatic cells are acquired by gene neosynthesis and neofunctionalization through alternative splicing of enzymatic messenger-/non-coding RNAs (m-/ncRNA) to isoforms that produce neoplastic effector proteins for translation , 4. It iGene translation is the final step in phenotypic expression of post-transcriptional genes and is therefore important in cancer formation and prevention. It is implemented in loops of interacting networks of epigenetic TFs involving alternatively spliced mRNA/ncRNA isoforms and effector proteins through binding sites at cis-reacting imprinting control regions (ICRs) and UTR (untranslated gene regions). Research on potential interactions between/among genes involved in gene translation in normal and neoplastic cell replications may help elucidate the mechanisms of cancer etiology and treatment.Epigenetic TFs control mitotic cell cycles as drivers. They originate in parental gametes and are transmitted transgenerationally to the fertilized ovum. In the zygote, pronuclear TFs interact with, and translate, genes of their fusion partners, trigger cleavages of the zygote, cause zygote-to-ES cell switches, and induce proliferation/differentiation of diploid gamete-to-zygote-to-embryonic stem (GZES) cells. It is now well established that parental occupational exposure to environmental carcinogens  causes dMemory is based on transcriptional decisions of parental genes on events of the past that are mitotically transmitted through TFs to ES cells. This requires erasure of preceding/ancestral DNA-CpG transcriptional patterns through excision-glycosylases converting DNA-CpG-5mC (5methyl-cytosine) to 5hmC (5hydroxy-methyl-cytosine), to 5cC (5carboxyl-cytosine) and, finally, to thymine , 17. ModMEGs)  at the 4–8 cell stage is implemented through MEG-dominated alterations of the CpG histone methylation status by gene-encoded methyltransferase/demethylases (DNMT/DM) /ZAR-like (ZARL) proteins in translational control sequences (TCS) that bind to maternal mRNAs at 3′UTR  and Piwil2 (protein of the ARGONAUTE family) (Mil1/Blimp1 (transcription repressors of somatic genes Hox and Snail). Maternal modulating TFs include cis-reacting RNA-binding proteins (RBPs), cytoplasmic polyadenylation elements (CPEs), and “deleted-azoospermia-like” (DAZL) family. CPEs mediate adaptation of gonadal homeostasis, metabolism, gene transcription of cell cycle cyclins, and apoptosis. DAZL is an mRNA translational component that controls RBP networks in the initial stages of zygote development until the embryonic genome is composed at the third post-fusion cleavage , Nlrp5 (Mater), subcortical maternal complexes (SCMC), Nlrp14 (nucleotide-binding oligomerization in early embryonic development), Hsf1 (heat shock), Npm2 (nucleoplasmin), Cdh1 (e-cadherin), Pms2 (mismatch repair gene2), Ezh2 , and Smarca 4 (Brg1).Transcriptional incompatibilities between parental pronuclei are silenced by histone-modulations during interactions in the zygote ensuring transcription stability in ES cell development.

They transmit genetic/epigenetic maternal memory information to the early stages of zygote-to-ES cell switches   , 36. IntGenes interact with enzymatic TFs at ICRs. ICRs are transcriptional/translational sites composed of repetitive, germline-derived, differentially methylated DNA sequences on chromosomes positioned between eu- and heterochromatin. They function as insulators in genomic reprograming by delimiting acetylation-mediated barriers against allele-specific interactions of somatic as well as imprinted genes . ICRs seGenes transcribed in mitoses become functional and exercise their properties through translation to effector proteins.A multifunctional mRNA-/polymerase A-binding protein (PABP1) serves as scaffold for protein–protein interactions. Production of effector proteins is mediated/controlled by translational TFs-mRNA/ncRNA. Indeed, unless genes are translated, genes are silenced and stored in heterochromatin. Thus, gene transcription and translation are interdependent but distinct and consecutive processes that can be separated by the specificities of their enzymes. Translating TFs include lysyl-tRNA synthetase (lysRS), isoform1 of translation elongation factor eEF that adjusts transcriptional yields to translational needs by associating with elongating RNA Pol II at 3′UTR, and cell fate effector DACHS. The latter mediates cytoplasmic oncogenic translation (for example in EMT) by affecting Y box-binding snail proteins. Clearly, it is translation that directs phenotypic expression of transcribed DNA sequences and therefore decides on the phenotypic, clinical expression of carcinogenic genes.Pre-mRNAs are formed from DNA templates at UTRs. They are specified by APA and RNA-recognition motifs (RRMs) for splicing into isoforms  with chAn important group among TFs is non-coding RNAs (ncRNA). They enzymatically regulate pre-mRNA splicing and edit mRNA-mediated gene transcription/translation , 45.

Furthermore, lncRNAs control gene transcription by recruitment of silencing complexes to homology-containing loci of the genome. Thus, lncRNAs are important in embryonic development and in the pathogenesis of neoplastic diseases /small interfering RNAs (s/siRNAs) , 50, 51,ipotency . Secondadiseases .An additional group of indispensible TFs, characterized as being “adjuvant,” is shown in Figure TFs are enzymes that do not catalyze their targets directly. Rather, they control protein production indirectly through isoform copies that are produced by alternate splicing.

Some switch to translation by neoplasm tic splicing only during proliferation; others, mostly of poor clinical prognosis, periodically turn dysregulated gene-specific ncRNA/mRNA interactions on and off. Still others monitor translation of gene transcriptomes by spontaneous expression of their own disease-associated isoforms without epigenetic triggers , 76. ForClearly, carcinogenic isoform variants of TFs are of key importance in neoplastic translation and phenotypic expression. This complies with the concept of carcinomas being epigenetic diseases .
