Project description:To find out the regulating pathways of AIP1 in Type 2 Diabetes, we performed a proteomic array of omental adipose tissue between obese T2D and obese patients.

Project description:Genes involved in the autophagic pathway are risk factors for the development of inflammatory bowel disease. In addition, patients with Crohn’s disease exhibit a profound expansion of mesenteric fat during the pathology. We investigated in our study the role of autophagy in mature adipocyte during intestinal inflammation. Mice bearing a tamoxifen-inducible deletion of Atg7 specifically in adipocytes showed signs of exacerbated intestinal inflammation in response to DSS-induced colitis. We therefore aimed to understand the possible underlying reasons for this change and performed a bulk RNA-seq approach using primary visceral adipocytes.
Project description:Obesity, a major risk factor for chronic diseases, is related to dsyfunctional adipose tissue signaling. First human trials suggest benefits of intermittent calorie restriction diet (ICR) in chronic disease prevention that may exceed those of continuous calorie restriction diet (CCR), even at equal net calorie intake. The effect of intermittent calorie restriction on adipose tissue signaling has not been investigated to date. Thus we initiated a randomized controlled trial to analyze the effect of ICR (eu-caloric diet on five days and two days per week with energy restriction of 75%), CCR (daily energy restriction of 20%) and a control group on subcutaneous adipose tissue (SAT) gene expression. 150 overweight or obese non-smoking adults (50 per group, 50% women) were randomly asiged to one of the study arms. SAT biopsies were taken before and after the 12 week intervention phase.
Project description:This SuperSeries is composed of the following subset Series: GSE25401: Adipose Tissue MicroRNAs as Regulators of CCL2 Production in Human Obesity [gene expression] GSE25470: Adipose Tissue MicroRNAs as Regulators of CCL2 Production in Human Obesity [miRNA data] GSE25910: Adipose Tissue MicroRNAs as Regulators of CCL2 Production in Human Obesity [differentiation data] Refer to individual Series
Project description:The aim of the project was to compare global gene expression in adipocytes from obese patients and lean controls. Subcutaneous adipose tissue was collected from severely obese patients undergoing bariatric surgery (average body-mass index (BMI) of 45.5 kg/m2 (n = 12, thereof 4 men) and healthy lean patients undergoing hernia repairs (average BMI of 24.2 kg/m2 (n = 12, thereof 7 men), between 27 and 56 years of age. Adipocytes were isolated by collagenase treatment of adipose tissue, followed by filtering and centrifugation. Floating adipocytes were lysed in Qiazol before RNA purification and microarray analysis.
