Representative Western blots and quantification of ATGL and HSL protein expression in adipose tissue biopsies of lean control (con), obese (ob) and obese + diabetes mellitus type 2 men of the visceral and subcutaneous depot (a–f). Equal loading of the blots was verified by reprobing the immunoblots with glyceraldehyde 3-phosphate (GAPDH) antibody. Correlation (r = 0.6, p < 0.18) between the size of visceral adipocytes and ATGL protein in subcutaneous adipose tissue in lean controls (e). *p < 0.05–0.10.
