High fat feeding and dietary l-arginine supplementation differentially regulate gene expression in rat white adipose tissue
Dietary l-arginine (Arg) supplementation reduces white-fat gain in diet-induced obese rats but the underlying mechanisms are unknown. This study tested the hypothesis that Arg treatment affects expression of gene...
