Project description:Profiling of the murine peptidome along the gastrointestinal tract and pancreas in vertical sleeve gastrectomy and sham operated mice. The study compares the peptidome of various portions of the GI tract using intact mass spectrometry and database searching. These peptides included most gut hormones including proglucagon derived peptides, PYY, GIP, somatostatin, neurotensin amongst others.
Project description:This study aimed at identifying differentially expressed protein-coding genes after bariatric surgery. Muscle biopsies were taken from vastus lateralis before and 3 months after bariatric surgery (i.e. sleeve gastrectomy or Roux-en-Y gastric bypass).
Project description:We report the expression profiles of ileal samples extracted from obese male C57Bl6 mice following vertical sleeve gastrectomy or sham surgery, focusing of gene signatures indicative of altered bile acid metabolism. We induced obesity in male C57bl6 mice through a high-fat diet. At 8 weeks, they were submitted to either a vertical sleeve gastrectomy (VSG) or a sham surgery; following surgery VSG mice were fed ad libitum while sham controls were pair-fed (SPF) to the experimental animals. During the four perioperative days, mice were fed a liquid Osmolite diet. Approximately 8 weeks after surgery mice were fasted overnight and gavaged with .5mL Osmolite; after one hour mice were sacrificed and the terminal ileum were extracted. RNA was extracted, quantified, and compared between VSG and SPF experimental groups.
Project description:lean control, obese, and formerly obese C57BL6N mice which underwent weight loss via vertical sleeve gastrectomy or calorie restriction were injected with E0771 cells and tumor growth was monitored
Project description:lean control, obese, and formerly obese C57BL6N mice which underwent weight loss via low-fat diet or verticle sleeve gastrectomy were injected with E0771 cells and tumor growth was monitored

Project description:Maternal sleeve gastrectomy in lean mice leads to small-for-gestational births and higher sensitivity of offspring to a high fat diet. These effects are reduced by maternal treatment with a Glp1 antagonist.
