Both proteins prolonged murine survival by increasing serum calcium, apparently by enhancing renal calcium transporter expression. The dominant effect on the skeleton was an increase in both endochondral bone and appositional formation without increased bone resorption.', 'PTH-related protein (PTHrP) was discovered as a hypercalcemic agent responsible for the syndrome of humeral hypercalcemia of malignancy, and PTH is the major protein hormone regulating calcium homeostasis. Both proteins have skeletal anabolic actions when administered intermittently. We examined effects of exogenous PTHrP(1-86) and PTH(1-34) in double null mutant mice deficient in both PTH and 25-hydroxyvitamin D-1alpha-hydroxylase [1alpha(OH)ase] to determine the action of these proteins in the absence of the two major regulators of calcium and skeletal homeostasis.', 'Mice heterozygous for the PTH null allele and for the 1alpha(OH)ase null allele were mated to generate pups homozygous for both null alleles. PTHrP(1-86) and PTH(1-34) were administered subcutaneously starting 4 days after birth. Serum biochemistry and skeletal radiology, histology, and histomorphometry were performed, and indices of bone formation, resorption, and renal calcium transport were determined by real time RT-PCR, Western blot, and immunohistochemical approaches.', 'In the double mutant mice, which die within 3 weeks after birth with severe hypocalcemia, tetany, and skeletal defects, exogenous PTHrP and PTH enhanced survival of the animals by improving serum calcium. Both proteins increased renal calcium transporter expression and long bone length and augmented growth plate chondrocyte proliferation, differentiation, and cartilage matrix mineralization. Cortical and trabecular bone mass was increased with augmented osteoblast number and activity; however, bone resorption was not increased.'] Do exogenous PTH-related protein and PTH improve mineral and skeletal status in 25-hydroxyvitamin D-1alpha-hydroxylase and PTH double knockout mice?

INPUT: ['Hand trauma is a top presenting complaint to hospital emergency departments (EDs) and can become costly if not treated effectively. The cornerstone for initial management of the traumatized hand is application of a splint. Improving splinting practice could potentially produce tangible benefits in terms of quality of care and costs to society.', 'We sought to determine the following: 1) whether the present standard of ED splinting was appropriate and 2) whether a strategically planned educational intervention could improve the existing care.', "We used a pre- and postprospective educational intervention study design. In the preintervention phase, patients referred to our hand clinic were assessed for injury and splint type. Splinting appropriateness was evaluated according to a predetermined hand surgeons' expert consensus. Next, an educational intervention was targeted at all ED staff at our institution. Postintervention, all patients were again evaluated for splint appropriateness. A follow-up evaluation was performed at 1\xa0year to see the long-term effects of the intervention.", 'The most common mechanism of injury of referred patients was falling (35%), and the most frequent injury was metacarpal fracture (40%). Splint appropriateness increased significantly postintervention from 49% to 69% (p\xa0=\xa00.048). At follow-up after 1\xa0year, splinting appropriateness was 70% (p\xa0=\xa00.041).'] Do an Educational Intervention to Improve Splinting of Common Hand Injuries? OUTPUT:

Our previous study indicated that ROC1 was essential for bladder cancer cell survival and that ROC1 knockdown inhibited CRL activity, triggering G2 phase arrest and senescence. However, the role of ROC1 in the malignant progression of bladder cancer remained unknown.', 'ROC1 expression in cancer cells was knocked down by siRNA silencing. The effects of ROC1 silencing were evaluated by in vitro assays for cell migration and by an in vivo mouse metastasis model. Epithelial-mesenchymal transition (EMT) induction was evaluated by immunofluorescence staining and western blotting of EMT-associated proteins. ROC1 expression in human tumours was further evaluated by immunohistochemical analysis.', 'ROC1 knockdown suppresses bladder cancer cell migration by inhibiting EMT. ROC1 knockdown inhibited EMT by inhibiting mammalian target of rapamycin (mTOR) activity via the accumulation of the mTOR-inhibitory protein DEPTOR, a CRL substrate. DEPTOR knockdown partially rescued ROC1 knockdown-inhibited EMT and the ROC1-induced inhibition of cancer cell migration. Furthermore, in vivo studies using a nude mouse metastasis model confirmed the in vitro data. Finally, tissue microarray analysis of clinical bladder cancer specimens indicated a positive correlation between ROC1 expression and EMT.'] Does regulator of cullins-1 expression knockdown suppress the malignant progression of muscle-invasive transitional cell carcinoma by regulating mTOR/DEPTOR pathway?
