Epstein-Barr virus glycoprotein gB and gHgL can mediate fusion and entry in trans, and heat can act as a partial surrogate for gHgL and trigger a conformational change in gB.
Liudmila S Chesnokova et al.
Journal of virology, 88(21), 12193-12201 (2014-08-22)
Epstein-Barr virus (EBV) fusion with an epithelial cell requires virus glycoproteins gHgL and gB and is triggered by an interaction between gHgL and integrin αvβ5, αvβ6, or αvβ8. Fusion with a B cell requires gHgL, gp42, and gB and is

Michela Sabbatucci et al.
Retrovirology, 12, 4-4 (2015-01-23)
Macrophages are key targets of HIV-1 infection. We have previously described that the expression of CC chemokine ligand 2 (CCL2) increases during monocyte differentiation to macrophages and it is further up-modulated by HIV-1 exposure. Moreover, CCL2 acts as an autocrine

Kwai Fung Hui et al.
British journal of haematology, 167(5), 639-650 (2014-08-27)
Epstein-Barr virus (EBV) latent proteins exert anti-apoptotic effects on EBV-transformed lymphoid cells by down-regulating BCL2L11 (BIM), CDKN2A (p16(INK4A) ) and CDKN1A (p21(WAF1) ). However, the potential therapeutic effects of targeting these anti-apoptotic mechanisms remain unexplored. Here, we tested both in

The Journal of physiology, 593(8), 2053-2069 (2015-02-03)
AMP-activated protein kinase (AMPK) is a regulator of energy homeostasis during exercise. Studies suggest muscle fibre type-specific AMPK expression. However, fibre type-specific regulation of AMPK and downstream targets during exercise has not been demonstrated. We hypothesized that AMPK subunits are

FEBS letters, 589(1), 138-144 (2014-12-06)
Inhibitors of histone deacetylases are frequently used against ischemia-induced injury, but the specific mechanisms of their action are poorly understood. Here, we report that following a 5-7-h oxygen-glucose deprivation (OGD) acetylation of histone H4 at residue K16 (H4K16Ac) decreases by

Stefan Brenner et al.
The contribution of organic anion transporting polypeptides (OATPs) to the cellular uptake of flavopiridol was investigated in OATP1B1-, OATP1B3- and OATP2B1-expressing Chinese hamster ovary (CHO) cells. Uptake of flavopiridol into these cells showed typical Michaelis-Menten kinetics with much higher transport
Membrane-bound complement regulatory proteins are prognostic factors of operable breast cancer treated with adjuvant trastuzumab: a retrospective study.
Mei Liu et al.
Oncology reports, 32(6), 2619-2627 (2014-09-23)
Complement-dependent cytotoxicity (CDC) is an important antitumor mechanism of monoclonal antibodies (mAbs). However, trastuzumab, an anti-HER2 mAb, exerts only minor CDC. Overexpression of membrane-bound complement regulatory proteins (mCRPs), which suppress CDC, have been implicated in various malignant tumors. Here, we

Naunyn-Schmiedeberg's archives of pharmacology, 387(9), 883-891 (2014-06-21)
Flavonoids such as quercetin and kaempferol mediate several health protective effects, e.g., anticancer effects. They are inhibitors of organic anion transporting polypeptides (OATP) and organic cation transporters (e.g., OCT2). However, little is known whether such transporters contribute to the cellular

Kaposi's sarcoma associated herpesvirus (KSHV) is associated with Kaposis's sarcoma (KS), primary effusion lymphoma and multicentric Castleman's disease. KSHV encodes at least 8 open reading frames (ORFs) that play important roles in its lytic DNA replication. Among which, ORF6 of
Colon cancer cell apoptosis is induced by combined exposure to the n-3 fatty acid docosahexaenoic acid and butyrate through promoter methylation.
Youngmi Cho et al.
Experimental biology and medicine (Maywood, N.J.), 239(3), 302-310 (2014-02-06)
DNA methylation and histone acetylation contribute to the transcriptional regulation of genes involved in apoptosis. We have demonstrated that docosahexaenoic acid (DHA, 22:6 n-3) and butyrate enhance colonocyte apoptosis. To determine if DHA and/or butyrate elevate apoptosis through epigenetic mechanisms thereby
