Insulin and GLP-1 infusions demonstrate the onset of adipose-specific insulin resistance in a large fasting mammal: potential glucogenic role for GLP-1

Prolonged food deprivation increases lipid oxidation and utilization, which may contribute to the onset of the insulin resistance associated with fasting. Because insulin resistance promotes the preservation of glucose and oxidation of fat, it has been suggested to be an adaptive response to food deprivation. However, fasting mammals exhibit hypoinsulinemia, suggesting that the insulin resistan...

Study of the potential association of adipose tissue GLP-1 receptor with obesity and insulin resistance.

The increase in glucagon-like peptide-1 (GLP-1) activity has emerged as a useful therapeutic tool for the treatment of type 2 diabetes mellitus. The actions of GLP-1 on β-cells and the nervous and digestive systems are well known. The action of this peptide in adipose tissue (AT), however, is still poorly defined. Furthermore, no relationship has been established between GLP-1 receptor (GLP-1R)...

The effects of twelve weeks of combined exercises on GLP-1 and insulin resistance in women with type 2 diabetes

Introdution: The purpose of this study was to investigate the effect of twelve weeks of combined exercise with two patterns (aerobic-resistance and resistance-aerobic) on GLP-1 and insulin resistance in women with type 2 diabetes. Methods: In this practical and semi-experimental study, 42 women with type 2 diabetes were divided into three groups: aerobic-resistance group (n=15), resistance-aer...

When GLP-1 hits the liver: a novel approach for insulin resistance and NASH.

NONALCOHOLIC FATTY LIVER DISEASE (NAFLD) encompasses a spectrum ranging from simple steatosis to steatohepatitis (NASH), increasing fibrosis and eventually, cirrhosis (22). Importantly, NASH accompanied by fibrosis and severe inflammation is the most relevant predictor for disease progression to cirrhosis and hepatocellular carcinoma (21). NAFLD is tightly associated with obesity, insulin resis...

Effects of Fasting on Glucagon-like peptide-1 hormone (GLP-1), and Lipid Profile Indices in Obese and Thin Women

Introduction: Glucagon-like peptide-1 hormone (GLP-1) contributes to the regulation of insulin and glucose concentration. However, the effects of fasting on GLP-1 response in different people has not been determined yet. The aim of the present research was to investigate the effect of fasting on GLP-1 and the lipid profile of obese and thin women.Materials and methods: In this research, 25 obes...
