Project description:The mechanisms of metabolic improvements following Roux-en-Y gastric bypass (RYGB) surgery are not entirely clear. Therefore, the aim of our study was to investigate the role of obesity and RYGB on the human skeletal muscle proteome.
Project description:The mechanisms of weight loss and metabolic improvements following bariatric surgery in skeletal muscle are not well known, however epigenetic modifications are likely to contribute. The aim of our study was to investigate skeletal muscle DNA methylation after weight loss induced by Roux-en-Y gastric bypass (RYGB) surgery.
Project description:miRNA profiles were investigated in skeletal muscle in severely obese individuals with or without diabetes before and after Roux-en-Y gastric bypass surgery.
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 performed single-nucleus RNA-seq on subcutaneous adipose tissue biopsies of 68 participants from the Roux-en-Y versus one-anastomosis gastric bypass (RYSA) cohort.

Project description:Weight Loss after Roux-En Y Gastric Bypass Surgery Reveals Novel Skeletal Muscle Promoter-Specific DNA Methylation Changes in Obese Patients
Project description:In order to identify mechanisms underlying the long-term beneficial effect of bariatric surgery on abdominal subcutaneous WAT, we performed gene microarray analyses on adipose tissue from a cohort of obese women. Adipose tissue biopsies were obtained before RYGB, and then 2 and 5 years thereafter. To evaluate the long-term effect of Roux-en-Y gastric bypass (RYGB) surgery on WAT, we also compared the WAT gene expression at 5 years postsurgery with that of age-matched nonoperated women.
