Introduction: Zinc α2-glycoprotein (ZAG) is a single-chain polypeptide with molecular weight of 40-kDa, and is secreted from various tissues. It plays several imperative functions in the human body, such as lipid mobilization and immunoregulation. ZAG enhances lipolysis and is involved in reduction of fatty acids in adipose tissues. ZAG has High sequence similarity to MHC-I molecules and is suggested to be a truncated secretory MHC-I–like protein. ...

Introduction: Widespread changes occur in gene expression in obesity, contributing to metabolic and inflammatory abnormalities. Epigenetic mechanisms play a role in obesity by altering gene expression patterns, and connecting environmental factors to genetic alterations. Histone acetylation is a crucial epigenetic modification that impacts chromatin structure and regulates gene expression. Adipogenesis has been associated with gene-specific increases in histon...

Introduction: obesity is a major health problem worldwide and its incidence is increasing annually. Adipose tissue produces and regulates many hormones and cytokines which have relationship with obesity comorbidity. Serum level of vitamin D has been previously reported to have a negative relationship with obesity.Objective: To evaluate the relationship between vitamin D status and leptin, adiponectin, lipid profile and I...

Introduction: Obesity is a rapidly growing health problem, with increasing worldwide prevalence. Obesity is accompanied by numerous metabolic and endocrine dysregulation. Thyroid dysfunction is one of the many metabolic aberrations that are associated with obesity. Thyroid dysfunction can be related to obesity, insulin resistance, and dyslipidemia. We aimed to study the thyroid function in children and adolescents with obesity and the metabolic parameters....

Introduction: Angiopoietin-like proteins (ANGPTLs) play critical roles in metabolism and are implicated in metabolic consequences of obesity. ANGPTL2 is a key adipocyte-derived inflammatory mediator that links obesity to systemic insulin resistance. ANGPTL3 directly regulate lipid, glucose and energy metabolism independent of angiogenic effects. In this study, we aimed to investigate the levels of ANGPTL2 and 3 in obese children and adolescents and their assoc...

Background: Ghrelin is a somatotropic and orexigenic protein secreted primarily from stomach.Objective and hypotheses: Since both GH secretion and nutrition, two fundamental contributors in growth promotion, are enhanced by ghrelin, the aim of this study was to investigate the relationship of ghrelin hormone with growth retardation in 3- to 16-year-old children and adolescents and determine whether ghrelin levels are different between normal subjects and...

Introduction: Obesity development and subsequent white adipose tissue (WAT) expansion is often accompanied by WAT fibrosis which leads to adipocyte dysfunction. Fibrosis is a condition in which extracellular matrix (ECM) proteins are increased aberrantly and results in immune cell infiltration, cytokine production and insulin resistance. Visfatin is an adipokine that is implicated in obesity and its metabolic consequences; however, its role in WAT fibrosis has...

Introduction: Obesity increases the risk of various disorders including diabetes, non-alcoholic fatty liver disease (NAFLD) and cardiovascular disorders. MicroRNAs (miRNA) are single-stranded, non-coding oligonucleotides that regulate gene expression. Sirtuin 1 (SIRT1), a regulatory enzyme in metabolic homeostasis, is regulated by miRNAs. The aim of this study was to evaluate miR-141 in obesity and whether this miRNA can regulate SIRT1 expression.Materia...

Background: Obesity is a major public health problem and its rate is increasing worldwide. Obesity accompanies perturbations in metabolism, conferring substantial excess risk for insulin resistance and Type 2 diabetes. Various genetic and epigenetic factors contribute to the development of obesity. MicroRNAs (miRNAs) are short noncoding RNAs involved in posttranscriptional regulation of gene expression and influence many cellular functions including glucose and lipid metabolis...

Background: Sirtuins are NAD+-dependant protein deacetylases that target histones, transcription factors, co-regulators, as well as metabolic enzymes to adapt gene expression and metabolic activity in response to the cellular energy state. SIRT1 and SIRT2 are two important enzymes of sirtuin family. SIRT1 has an important role in glucose metabolism and improves glucose homeostasis. It can also regulate fatty acid oxidation and hepatic cholesterol and bile acid metab...
