Fat tissue from omenta, thigh and abdomen taken under anesthesia on subjects undergoing laparoscopic surgery, cholecystectomy, reflux surgery or gastric by-pass (GBP).

Are there any difference in polymorphids and/or mRNA expression in genes significant for developing obesity, between normal weight and obese individuals, with or without diabetes typ 2 .

Are there any difference in polymorphids and/or mRNA expression in different types of fat tissue

  • Difference in polymorphids and/or mRNA expression in different types of fat tissue in patients with normal weight or obesity with or without diabetes type 2 [ Time Frame: approximatly 30 minutes after start of operation ]
    fat biopsy; abdomen, omenta and thigh taken at surgery
