Objective(s): Hyperglycemia induces cellular senescence in various body cells, such as vascular endothelial cells. Since the vessels are highly distributed in the body and nourish all tissues, vascular damages cause diabetes complications such as kidney failure and visual impairment. Alpha-mangostin is a xanthone found in mangosteen fruit with protective effects in met...

Islets are composed mostly of beta-cells, and therefore stem cell research has concentrated on generating purified beta-cells, neglecting the other endocrine cell types in the islet. We investigated the presence of endocrine non-beta-cells after islet transplantation. In addition, we studied whether the transplantation of pure beta-cells, in volumes similar to that used in islet transplantation...

It is well-established that insulin-producing pancreatic beta cells are central in diabetes. In type 1 diabetes, beta cells are destroyed by an autoimmune mechanism, whereas in type 2 diabetes, there is a decrease in functional beta-cell mass. In this context, studying beta cells is of major importance. Beta cells represent only 1% of total pancreatic cells and are found dispersed in the pancre...

Background: Curcumin, extracted from turmeric, represents enormous potential to serve as an anticancer agent. Telomerase is viewed as a prominent molecular target of curcumin, and transforming growth factor-β1 (TGFβ1) has proven to be a major inhibitory signaling pathway for telomerase activity. In the current study, we aimed to explore suppressive effects of nanocurcumin on telomeras...

Background & Objective: Angiopoietin-like Proteins 8 (ANGPTL8) which secreted form adipose tissue due to downstream PGC-1α pathways, is the main factor for regeneration of beta cell. The aim of this study was to investigate the effect of 4 endurance training program on PGC-1α expression in adipose tissue, ANGPTL8 serum concentration and beta cell function (HOMA.B) in diabetic rats. Materials & ...

Aim and Background: Considering the high rates of diabetes in Iran and the world and also due to the lower side effects of medicinal plants compared to industrial and chemical arbitrators, this study examined the effect of the active ingredient of tall moss (silymarin) on the expression of pax4 gene, one of the key genes for development and reconstruction of pancreatic beta cells.   Material ...

Abstract The biosynthesis of insulin takes place in the insulin-producing beta cells that are organized form islets Langerhans together with a few other islet cell types pancreas organ. signal for glucose-induced secretion is generated two pathways mitochondrial metabolism pancreatic cells. These also known as triggering pathway and amplifying pathway. Glucokinase, low-affinity glucose-phosphor...

Introduction: Type I diabetes mellitus is caused by autoimmune destruction of the insulin-producing β-cells. A new potential method for curing the disease is transplantation of differentiated insulin- secreting cells from human embryonic stem cells. Methods: Human embryonic stem cell lines (Royan H1) were used to produce embryoid bodies. Differentiation carried out by growth factor-mediated se...

mesenchymal stem cells (mscs) have the ability to differentiate into neuronal like cells under appropriate culture condition. in this study, we investigated whether mscs derived from human peripheral blood (pb-mscs) can differentiate into neuronal like cells by synergic effect of the growth factors egf, bfgf and noggin. for this purpose, the expression of five neuronal markers (nestin, β iii tu...
