HIF-1α expression in visceral adipose tissue (VAT) in non-obese and morbidly obese subjects with low (MO-low-IR) and high insulin resistance (MO-high-IR) in fasting condition. a HIF-1α mRNA and b representative immunoblot from non-obese and morbidly obese subjects (n = 4 per group). The results are given as the mean ± SEM. ^aP < 0.05 significant differences respect to the non-obese group. A.U. arbitrary units
