Recent studies indicate that Family with sequence similarity 20 member C (FAM20C) catalyzes the phosphorylation of secreted proteins, and participates in a variety of biological processes, including cell proliferation, migration, mineralization and phosphate homeostasis. To explore the local influences of FAM20C on osteoblast, Fam20c-deficient osteoblasts were generated by treating the immortalized Fam20c(f/f) osteoblasts with CMV-Cre-IRES-EGFP lentivirus. Compared with the normal Fam20c(f/f) osteoblasts, the expression of Bone sialoprotein (Bsp), Osteocalcin (Ocn), Fibroblast growth factor 23 (Fgf23) and transcription factors that promote osteoblast maturation were up-regulated in the Fam20c-deficient osteoblasts...

BACKGROUND: Lay health workers (LHWs) are increasingly used to complement health services internationally. Their perceptions of the interventions they implement and their experiences in delivering community based interventions in India have been infrequently studied. We developed a novel LHW led intervention to improve anemia cure rates in rural community dwelling children attending village day care centers in South India. Since the intervention is delivered by the village day care center LHW, we sought to understand participating LHWs' acceptance of and perspectives regarding the intervention, particularly in relation to factors affecting daily implementation...

Bovine satellite cell (bSC) myogenesis and skeletal muscle hypertrophy occur through the orchestrated actions of multiple autocrine and paracrine growth factors. Intimate to the bSC niche is IL6, a dual-purpose cytokine with proinflammatory and mitogenic properties. The objective of the experiment was to examine the effects of IL6 on proliferation and differentiation of bSC in vitro. Treatment of primary bSC cultures with recombinant bovine IL6 (bIL6) failed to alter myogenesis owing to the absence of intracellular signal transduction...

The present study explored the possible preventive effects of dietary glutamate (Glu) on LPS-induced oxidative damage, mRNA expression changes of tight junction (TJ) proteins and defensins, inflammatory and apoptosis response signaling molecules in fish intestine. Young Jian carp were fed five diets supplemental graded levels of Glu (0, 4, 8, 16 and 32 g kg(-1) diet) for 63 days. The results indicated that Glu supplementation depressed LPS induced the production of reactive oxygen species (ROS) and severe oxidative damage (lipid peroxidation and protein oxidation) in fish intestine, which was partially due to the increased glutathione (GSH) content and antioxidant enzyme activities including superoxide dismutase (SOD), glutathione peroxidase (GPX), glutathione-S-transferase (GST), and glutathione reductase (GR) (P < 0...

Cytoglobin (CYGB) belongs to the mammalian globin family and is exclusively expressed in hepatic stellate cells (HSCs) in the liver. In addition to its gas-binding ability, CYGB is relevant to hepatic inflammation, fibrosis, and cancer because of its antioxidative properties; however, the regulation of CYGB gene expression remains unknown. Here, we sought to identify factors that induce CYGB expression in HSCs and to clarify the molecular mechanism involved. We used the human HSC cell line HHSteC and primary human HSCs isolated from intact human liver tissues...

Pulmonary hypertension (PH) is a devastating pulmonary vascular disease characterized by aberrant muscularization of the normally non-muscularized distal pulmonary arterioles. The expression of the transcription factor, Twist1, increases in the lungs of pulmonary arterial hypertension patients. However, the mechanisms by which Twist1 controls the pathogenesis of PH remain unclear. It is becoming clear that endothelial-to-mesenchymal transition (EndMT) contributes to various vascular pathologies including PH; Twist1 is known to mediate EndMT...

Philip C Calder
Inappropriate, excessive or uncontrolled inflammation contributes to a range of human diseases. Inflammation involves a multitude of cell types, chemical mediators and interactions. The present article will describe nutritional and metabolic aspects of omega-6 (n-6) and omega-3 (n-3) fatty acids and explain the roles of bioactive members of those fatty acid families in inflammatory processes. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are n-3 fatty acids found in oily fish and fish oil supplements...

Rabbit induced pluripotent stem cells (rbiPSCs) possess the characteristic features of primed pluripotency as defined in rodents and primates. In the present study, we reprogrammed rbiPSCs using human Krüppel-like factors (KLFs) 2 and 4 and cultured them in a medium supplemented with fetal calf serum and leukemia inhibitory factor. These cells (designated rbEKA) were propagated by enzymatic dissociation for at least 30 passages, during which they maintained a normal karyotype. This new culturing protocol resulted in transcriptional and epigenetic reconfiguration, as substantiated by the expression of transcription factors and the presence of histone modifications associated with naïve pluripotency...

The leucine responsive regulatory protein (Lrp) is a global transcription factor that regulates the expression of genes involved in amino acid metabolism. To identify metabolic pathways and related genes under the control of Lrp in the acetic acid bacterium Komagataeibacter europaeus, the Kelrp null mutant (KGMA7110), which requires supplementation of all 20 amino acids for normal growth, was cultivated in minimal media containing or lacking particular amino acids. The results confirmed that KGMA7110 was auxotrophic for methionine and its catabolites S-adenosylmethionine (SAM) and spermidine (SPD)...

Toxicity by aluminum is a growth-limiting factor in plants cultivated in acidic soils. This metal also promotes signal transduction pathways leading to the biosynthesis of defense compounds, including secondary metabolites. In this study, we observed that Coffea arabica L. cells that were kept in the dark did not produce detectable levels of caffeine. However, irradiation with light and supplementation of the culture medium with theobromine were the best conditions for cell maintenance to investigate the role of aluminum in caffeine biosynthesis...

Alcoholic fatty liver is the earliest stage of alcohol-induced liver disease leading to liver cirrhosis. β-Conglycinin, one of the soy proteins, is known to prevent non-alcoholic fatty liver, hyperlipidemia and obesity. Therefore, we examined whether β-conglycinin feeding has an effect on the prevention of acute ethanol-induced fatty liver in mice. Male C57BL/6J mice were fed with 20 energy% β-conglycinin or casein for 4 weeks prior to ethanol administration and were then given ethanol or glucose, as a control, by gavage...

Chronic hypoxia is associated with muscle wasting and decreased oxidative capacity. By contrast, training under hypoxia may enhance hypertrophy and increase oxidative capacity as well as oxygen transport to the mitochondria, by increasing myoglobin (Mb) expression. The latter may be a feasible strategy to prevent atrophy under hypoxia and enhance an eventual hypertrophic response to anabolic stimulation. Mb expression may be further enhanced by lipid supplementation. We investigated individual and combined effects of hypoxia, insulin-like growth factor (IGF)-1 and lipids, in mouse skeletal muscle C2C12 myotubes...
