Role of Sp1 in insulin regulation of gene expression.
Sp1 is a ubiquitous nuclear factor that plays a key role in maintaining basal transcription of 'house-keeping' genes. However, recent evidence points to a more important function for Sp1 in mediating 'cross-talk' between selected signaling cascades to regulate the target genes that respond to these pathways. The role of Sp1 in mediating the actions of the peptide hormone insulin is of specific ...
متن کاملGlucose regulation of insulin gene expression in pancreatic β-cells
Production and secretion of insulin from the β-cells of the pancreas is very crucial in maintaining normoglycaemia. This is achieved by tight regulation of insulin synthesis and exocytosis from the β-cells in response to changes in blood glucose levels. The synthesis of insulin is regulated by blood glucose levels at the transcriptional and post-transcriptional levels. Although many transcripti...
متن کاملFeedback inhibition of insulin gene expression by insulin.
To examine the possible involvement of insulin and glucose in regulation of pancreatic islet gene expression, hyperinsulinemic (insulin infusion 4.1 mU/kg per min) clamps were performed for 12 h in rats at two different levels of glycemia (either 3 or 8 mM). A control group received a saline infusion for 12 h. At the end of the 12-h study period, pancreatic RNA was extracted, proinsulin and amy...
متن کاملAntihyperglycemic effect of Rosa damascena is mediated by PPAR.γ gene expression in animal model of insulin resistance
Insulin resistance is a condition in which insulin signaling and action are impaired in insulin sensitive tissues and results in hyperglycemia, hyperlipidemia and type 2 diabetes mellitus. Our previous studies have shown that rosa damascena has antihyperglycemic effects on diabetic and normal rats. Therefore, we conducted a study to evaluate the effect of this medicinal plant on insulin sensiti...
