Effect of the G-protein beta 3 subunit 825T allele on the change of body adiposity in obese female

초록

No clinical studies on the lipolytic effect of guanine nucleotide-binding protein beta 3 subunit gene (GNB3) 825T polymorphism have been performed. This study was a subinvestigation of a 12-week randomized controlled trial (NCT01184560) for the additive effect of orlistat on sibutramine treatment. The analysis involved 101 obese females aged 1849 years, genotyped at the GNB3 825 locus. To exclude any influence from potential confounders, we used an analysis of covariance model. After the intervention, fat mass proportion in total weight loss was significantly lower in subjects with a T allele than in those without a T allele (p?=?0.034). GNB3 825T allele was associated with blunted fat mass reduction in obese females.
