The role of noggin in regulation of high glucose-induced apoptosis and insulin secretion in INS-1 rat beta cells

Objective(s):The purpose of this study was to investigate the effects of Noggin on high glucose-induced apoptosis and insulin secretion in pancreatic beta cells. Materials and Methods: Different concentrations of glucose were used to examine their effects on INS-1 rat beta cells in vitro. When specific siRNA targeting Noggin and recombinant Noggin were added, apoptosis and insulin secretion wer...

بررسی اثر گلوکزآمین بر فعالیت آنزیم‌های گلوکوکیناز و هگزوکیناز پانکراس و ارتباط آن با ترشح انسولین از جزایر لانگرهانس موش‌های صحرایی سالم و دیابتی نوع 2

Background: Glucokinase serves as a glucose sensor in pancreatic β-cells and plays a key role in glucose homeostasis and glucose-stimulated insulin secretion (GSIS). In the present study we examined the effect of glucosamine, a glucokinase inhibitor, on the pancreatic glucokinase and hexokinase activities and on insulin secretion from freshly rat pancreatic islets of Langerhans. Insulin concen...

The effect of ghrelin on Kiss-1 and KissR gene transcription and insulin secretion in rat islets of Langerhans and CRI-D2 cell line

Objective(s): Ghrelin is a peptide hormone that has been shown to have numerous central and peripheral effects. The central effects including GH secretion, food intake, and energy homeostasis are partly mediated by Kiss1- KissR signaling pathway. Ghrelin and its receptor are also expressed in the pancreatic islets. Ghrelin is one of the key metabolic factors controlling insulin secretion from t...

Salvianolic acid B improves insulin secretion from interleukin 1β-treated rat pancreatic islets: The role of PI3K-Akt signaling

Background and Objective: Oxidative stress induced by proinflammatory cytokines such as IL-1β plays a major role in β-cell destruction in diabetes type 1. Salvianolic acid B (Sal B) is a polyphenolic compound with antioxidant and protective effects. Thus, objective of this study was to assess the protection exerted by Sal B on isolated rat islets exposed to IL-1β and to investigate an underlyin...

بررسی اثر گلی‌بن‌کلامید بر ترشح انسولین و فعالیت گلوکوکیناز در جزایر لانگرهانس پانکراس موش‌های صحرایی سالم و دیابتی

Background: Sulfonylurea agents such as Glibenclamide (Glyburide) have been widely prescribe in treatment of type 2 diabetic patients for decades, but controversy remains about their precise mechanism of action. On the other hand, glucokinase serves as a glucose sensor in pancreatic β-cells and plays a key role in the regulation of insulin secretion and glucose homeostasis. The aim of the pres...
