Comment Chronic glucose feeding (10% glucose in addition to normal chow diet for 4 weeks) resulted in significant decrease of PPARgamma level in aorta and heart tissues. Supplementation of alpha-lipoic acid not only prevented the decrease of PPARgamma, but also increased PPARgamma levels in aorta and heart tissues.
