Metabolic syndrome has a high prevalence (about 22.4% in adult individuals) in developed countries. Inflammation due to obesity and fat accumulation is the most important factor in the progression of metabolic syndrome. In cells which have a receptor for insulin hormone, inflammatory mediators target the insulin signaling pathway and cause insulin resistance. Peroxisome proliferator-activated r...
Immortalized brown adipocyte cell lines have been generated from fetuses of mice deficient in the insulin-like growth factor I receptor gene (IGF-IR(-/-)), as well as from fetuses of wild-type mice (IGF-IR(+/+)). These cell lines maintained the expression of adipogenic- and thermogenic-differentiation markers and show a multilocular fat droplets phenotype. IGF-IR(-/-) brown adipocytes lacked IG...
An important goal in diabetes research is to understand the processes that trigger endogenous β-cell proliferation. Hyperglycemia induces β-cell replication, but the mechanism remains debated. A prime candidate is insulin, which acts locally through the insulin receptor. Having previously developed an in vivo mouse hyperglycemia model, we tested whether glucose induces β-cell proliferation thro...
background: to evaluate the effect of exendine-4 (ex-4), a glucagon-like peptide 1 (glp-1) receptor agonist, on the differentiation of insulin-secreting cells (ipcs) from rat adipose-derived mesenchymal stem cells(admscs). materials and methods: in this experimental study, admscs were isolated from rat adipose tissue and exposed to induction media with or without ex-4. after induction, the exis...
Oxidative stress is thought to play a role in the development of insulin resistance. In order to elucidate the molecular effect of oxidative stress on liver insulin signaling, we analyzed the effect of paraquat (1,1-dimethyl-4,4-dipyridynium; PQ)-derived oxidative stress on the expression of insulin-dependent genes and activation of liver insulin signaling pathway. Incubation of primary culture...
OBJECTIVE It was reported that the long-acting insulin analogue glargine induces cell proliferation in a human osteosarcoma cell line and therefore might induce or accelerate tumor growth. Induction of cell proliferation would be particularly relevant for insulin treatment of subjects with diabetes and the potential of bearing tumor cells (e.g., a history of a malignant disease). RESEARCH DES...
