Objective(s): The present study aimed to evaluate the receptor of advanced glycation end-products (RAGE), NF-kB, NRF2 gene expression, and RAGE cell distribution in peripheral blood mononuclear cells (PBMC) in subjects with obesity and IR compared with healthy subjects.Materials and Methods: The mRNA expression levels of RAGE, NF-kB, NRF...

Ob/ob mice are leptin-deficient animals with uninhibited food intake and susceptibility to gain weight develop type 2 diabetes. The have been used study obesity We generated a dataset of different tissue gene expressions from wild-type ob/ob normal diet (ND) or high-fat (HFD). expression was profiled at genome-scale using RNA-seq. deposited the raw data short read archive processed omnibus. In ...

leptin is secreted mainly by fat, which is involved in energy metabolism and reproduction. leptin and itsreceptor (ob-r) have been detected in human spermatozoa and testis, thus it can be concluded leptin involves in male physiology. the goal of this study was determination of the presence of leptin receptor mrna in the ram testis, epididymis and spermatozoa by reverse transcription polymerase ...

The ob gene product is known to control food intake and energy expenditure. To determine whether thermogenic agents directly control ob gene expression, the effects of beta-adrenoceptor agonists on the level of the ob gene messenger RNA (mRNA) and on leptin secretion have been studied in mouse brown adipocytes differentiated in culture. These cells highly expressed the beta 3-adrenoceptor, the ...

Events of the past twelve months have had an explosive impact on the field of obesity research. This wave of excitement was triggered by a momentous announcement from Zhang et al. [1] in December 1994. The authors reported that they had identified the gene responsible for obesity in one of the most intensively studied genetic rodent models of the disorder, the ob/ob mouse, homozygous for a muta...

The recently identified mouse obese (ob) gene apparently encodes a secreted protein that may function in the signaling pathway of adipose tissue. Mutations in the mouse ob gene are associated with the early development of gross obesity. A detailed knowledge concerning the RNA expression pattern and precise genomic location of the human homolog, the OB gene, would facilitate examination of the r...

The leptin receptor (OB-R) is a single membrane- spanning protein that mediates the weight-regulatory effects of leptin (OB protein). Several mRNA splice variants have been described which either encode OB-R proteins with cytoplasmic domains of different length or the OB-R and B219/OBR variants, which have different 5'-untranslated regions. Here we report evidence for the synthesis of a human m...

Nonalcoholic fatty liver disease (NAFLD) is highly prevalent and associated with considerable morbidities. Unfortunately, there is no currently available drug established to treat NAFLD. It was recently reported that intraperitoneal administration of taurine-conjugated ursodeoxycholic acid (TUDCA) improved hepatic steatosis in ob/ob mice. We hereby examined the effect of oral TUDCA treatment on...

Mice with mutations of the ob gene are extremely obese, and the human homologue (OB) has been cloned and physically mapped. The protein product of the ob gene (leptin) reduces body fat in mice when given exogenously, and leptin has been proposed to provide a lipostatic signal that regulates adiposity. Variation in the OB gene may be one genetically determined cause of obesity in human populatio...

The product of the obese (ob) gene, leptin, is a secreted protein that is important in the regulation of body weight. Mice with mutations in the ob gene are obese and diabetic and manifest reduced physical as well as metabolic activity. In this study, we tested the possibility that mutations in the OB gene may contribute to human obesity. We report the isolation and partial sequence of the huma...
