The Synergistic Effect of an ATP-Competitive Inhibitor of mTOR and Metformin on Pancreatic Tumor Growth.

Background: The mechanistic target of rapamycin complex 1 (mTORC1) is a nutrient-sensing pathway and a key regulator of amino acid and glucose metabolism. Dysregulation of the mTOR pathways is implicated in the pathogenesis of metabolic syndrome, obesity, type 2 diabetes, and pancreatic cancer.

Objectives: We investigated the impact of inhibition of mTORC1/mTORC2 and synergism with metformin on pancreatic tumor growth and metabolomics.

Effects of Metformin and a Mammalian Target of Rapamycin (mTOR) ATP-Competitive Inhibitor on Targeted Metabolomics in Pancreatic Cancer Cell Line.

Pancreatic Cancer (PC) is a devastating lethal disease. Therefore, there is an urgent need to develop new intervention strategies. The mammalian Target of Rapamycin (mTOR) is a conserved kinase and master regulator of metabolism and cell growth.

Effects of exendin-4 alone and with peptide YY(3-36) on food intake and body weight in diet-induced obese rats.

Significant weight loss following Roux-en-Y gastric bypass surgery (RYGB) in obese humans correlates with enhanced secretion of anorexigenic gut hormones glucagon-like peptide-1 (GLP-1) and peptide YY(3-36) (PYY(3-36)). Our aim here was to identify a dosing strategy for intraperitoneal (IP) infusion of GLP-1 homologue exendin-4 alone and with PYY(3-36) that produces a sustained reduction in daily food intake and body weight in diet-induced obese (DIO) rats. We tested 12 exendin-4 strategies over 10 weeks.
