The elongation of very long chain fatty acids protein 6 (ELOVL6) encodes a fatty acid elongase that is responsible for the final step in endogenous saturated fatty acid synthesis and involves in de novo lipogenesis. Though the regulatory mechanism of ELOVL6 expression has been studied extensively, little is known about the role of miRNA in regulating ELOVL6 gene expression in chicken until now. To investigate the regulatory mechanism of miRNA on the expression of ELOVL6 gene, bioinformatics analysis was employed to predict the potential miRNAs that binding with the 3'untranslated region (3'UTR) of ELOVL6...

Plants produce an immense diversity of natural products (i.e. secondary or specialized metabolites) that offer a rich source of known and potentially new pharmaceuticals and other desirable bioproducts. The Traditional Chinese Medicinal plant Isodon rubescens (Lamiaceae) contains an array of bioactive labdane-related diterpenoid natural products. Of these, the ent-kauranoid oridonin is the most prominent specialized metabolite that has been extensively studied for its potent antimicrobial and anticancer efficacy...

PURPOSE: Early diagnosis and treatment of multiple sclerosis-related progressive multifocal leukoencephalopathy (PML) significantly improve clinical outcomes. However, there is a lack of information regarding the restart of immunomodulatory therapy in the post-PML setting, when multiple sclerosis activity reappears. We aimed at the examination of metabolic differences using 1H-magnetic resonance spectroscopy (1H-MRS) in multiple sclerosis patients at various post-PML stages and at the exploration of differences according to their disease and JC virus (JCV) status...

Two bell pepper (Capsicum annuum) cultivars, differing in their response to chilling, were exposed to three levels of root zone temperatures. Gas exchange, shoot and root phenology, and the pattern of change of the central metabolites and secondary metabolites caffeate and benzoate in the leaves and roots were profiled. Low root zone temperature significantly inhibited gaseous exchange, with a greater effect on the sensitive commercial pepper hybrid (Canon) than on the new hybrid bred to enhance abiotic stress tolerant (S103)...

The mechanism for different susceptibilities to obesity after short-term high-fat diet (HFD) feeding is largely unknown. Given the close association between obesity occurrence and mitochondrial dysfunction, the early events in skeletal muscle mitochondrial adaptations between HFD-induced obesity (DIO) and HFD-induced obesity resistant (DIO-R) lean phenotype under excess nutritional environment were explored.ICR/JCL male mice were randomly divided into 2 groups, as follows: low-fat diet (LFD) and HFD groups...

Type 2 diabetes mellitus (T2DM) has growing prevalence worldwide and major clinical implications, chiefly cardiovascular (CV) and renal disease burden. Sodium-glucose co-transporter (SGLT)-2 inhibitors are a new drug class in the management of T2DM with a mechanism of action independent of insulin. In addition to their hypoglycaemic effect, SGLT-2 inhibitors appear to have haemodynamic and nephroprotective effects. Studies have consistently showed a modest but significant blood pressure (BP) reduction. Metabolic benefits are also attributed to SGLT-2 inhibitors with a modest but consistent body weight decrease recorded along with improvements in lipid profile and uric acid levels...

Study objectives: Shortened or mistimed sleep affects metabolic homeostasis, which may in part be mediated by dysregulation of endogenous circadian clocks. In this study, we assessed the contribution of sleep disruption to metabolic dysregulation by analysing diurnal transcriptome regulation in metabolic tissues of mice subjected to a sleep restriction paradigm. Methods: Male mice were subjected to 2x5 days of sleep restriction (SR) with enforced waking during the first six hours of the light phase...

INTRODUCTION: Familial partial lipodystrophy (FPL) is a rare genetic disorder characterized by selective lack of subcutaneous fat, which is associated with insulin-resistant diabetes. The Dunnigan variety (FPLD2) is caused by several missense mutations in the lamin A/C (LMNA) gene, most of which are typically located in exon 8 at the codon position 482. OBJECTIVE: The aim of this study was to assess and compare the dietary intake, leisure-time physical activity (LTPA), and biochemical measurements (glucose, A1C, and plasma lipids) in women with FPLD2 and without (control group, CG) and to examine the associations between dietary intake and biochemical measurements (BM)...

BACKGROUND: Inflammatory and immune processes can be triggered in vitiligo due to decreased number of the melanocytes and their anti-inflammatory effects. Because of systemic nature of vitiligo, metabolic abnormalities such as insulin resistance and lipid profile disturbances as well as skin involvement may be observed in vitiligo. AIMS: To investigate the association between MetS and vitiligo. STUDY DESIGN: A case-control study. METHODS: The demographic, clinical and laboratory features in the subjects were compared according to presence of vitiligo and MetS [patients (n=63) vs gender-age matched controls (n=65) and MetS positive (n=38) vs negative (n=90)]...

Cytosolic glyceraldehyde-3-phosphate dehydrogenase (NAD-GAPDH) is involved in a critical energetic step of glycolysis and also has many important functions besides its enzymatic activity. The recombinant wheat NAD-GAPDH was phosphorylated in vitro at Ser205 by a SNF1-Related protein kinase 1 (SnRK1) from wheat heterotrophic (but not from photosynthetic) tissues. The S205D mutant enzyme (mimicking the phosphorylated form) exhibited a significant decrease in activity but similar affinity toward substrates. Immunodetection and activity assays showed that NAD-GAPDH is phosphorylated in vivo, the enzyme depicting different activity, abundance and phosphorylation profiles during development of seeds that mainly accumulate starch (wheat) or lipids (castor oil seed)...

Helicobacter pylori is a Gram-negative bacterium that colonizes the human gastric mucosa and causes peptic ulcers and gastric carcinoma. H. pylori strain 26695 has a small genome (1.67 Mb), which codes for few known transcriptional regulators that control bacterial metabolism and virulence. We analyzed by qRT-PCR the expression of 16 transcriptional regulators in H. pylori 26695, including the three sigma factors under different environmental conditions. When bacteria were exposed to acidic pH, urea, nickel, or iron, the sigma factors were differentially expressed with a particularly strong induction of fliA...

Objectives: The nutraceutical approach to the management of metabolic syndrome (MetS) might be a promising strategy in the prevention of cardio-metabolic risk. Low-dose bergamot-derived polyphenolic fraction (BPF) has been proven effective in patients with MetS, as demonstrated by a concomitant improvement in lipemic and glycemic profiles. The present study was aimed to further explore, in a sample of subjects receiving second generation antipsychotics (SGAs), the effects on body weight and metabolic parameters of a low dose of BPF (500 mg/day) administered for 60 days...

In contrast to the widely accepted consensus of the existence of a single RNA polymerase in bacteria, several actinomycetes have been recently shown to possess two forms of RNA polymerases due the to co-existence of two rpoB paralogs in their genome. However, the biological significance of the rpoB duplication is obscure. In this study we have determined the genome sequence of the lipoglycopeptide antibiotic A40926 producer Nonomuraea gerenzanensis ATCC 39727, an actinomycete with a large genome and two rpoB genes, i...

BACKGROUND: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is characterized by unexplained persistent fatigue, commonly accompanied by cognitive dysfunction, sleeping disturbances, orthostatic intolerance, fever, lymphadenopathy, and irritable bowel syndrome (IBS). The extent to which the gastrointestinal microbiome and peripheral inflammation are associated with ME/CFS remains unclear. We pursued rigorous clinical characterization, fecal bacterial metagenomics, and plasma immune molecule analyses in 50 ME/CFS patients and 50 healthy controls frequency-matched for age, sex, race/ethnicity, geographic site, and season of sampling...

Carbohydrate ingestion can improve endurance exercise performance. In the past two decades, research has repeatedly reported the performance benefits of formulations comprising both glucose and fructose (GLUFRU) over those based on glucose (GLU). This has been usually related to additive effects of these two monosaccharides on the gastrointestinal tract whereby intestinal carbohydrate absorption is enhanced and discomfort limited. This is only a partial explanation, since glucose and fructose are also metabolized through different pathways after being absorbed from the gut...

Previously, we found that phenolic content and antioxidant capacity (AOX) in carrots increased with wounding intensity. It was also reported that UV radiation may trigger the phenylpropanoid metabolism in plant tissues. Here, we determined the combined effect of wounding intensity and UV radiation on phenolic compounds, AOX, and the phenylalanine ammonia-lyase (PAL) activity of carrots. Accordingly, phenolic content, AOX, and PAL activity increased in cut carrots with the duration of UVC radiation, whereas whole carrots showed no increase...

Avian Influenza virus (AIV) is a major concern for the global poultry industry. Since 2012, several countries have reported AIV outbreaks among domestic poultry. These outbreaks had tremendous impact on poultry production and socio-economic repercussion on farmers. In addition, the constant emergence of highly pathogenic AIV also poses a significant risk to human health. In this study, we used a chicken lung epithelial cell line (CLEC213) to gain a better understanding of the molecular consequences of low pathogenic AIV infection in their natural host...

PURPOSE OF REVIEW: The pathophysiologies of nonalcoholic fatty liver disease (NAFLD), metabolic syndrome, and cardiovascular disease are closely interlinked and associated with atherogenic dyslipidemia. Liver and cardiovascular disease may silently progress to advanced stages if alarming signs, such as abdominal obesity, elevated fasting and postprandial triglycerides, and low HDL cholesterol are overlooked. We review the metabolic mechanisms in NAFLD at the cellular level in the context of standard clinical lipid measurements...
