Polymorphids an mRNA Expression in Obese Genes

August 21, 2013 updated by: Anders Thorell, Karolinska Institutet

Polymorphids and mRNA Expression in Genes, Significant for Developing Obesity and Typ II Diabetes in Different Types/Localisations of Fat Tissue

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
