Aim. Peroxisome proliferator activated receptor gamma (PPARG) and PPARG coactivator 1α (PPARGC1A) is a key regulator of energy metabolism. This study examines the influence of PPARG and PPARGC1A gene polymorphisms on the PPARG expression, obesity risk, lipoprotein profile and effectiveness of the physical activity intervention for improvement of these parameters. Methods. 39 women with BMI>30 kg/m2 participated in the three-months fitness-program and followed a hypocaloric diet (1500 kCal). At the beginning and at the end of the program, the following anthropometric and biochemical parameters were measured: BMI, percentage of total and visceral fat, amount of plasma lipoproteins, cholesterol, and triglycerides. Single nucleotide polymorphisms were identified in PPARG (n=94) and PPARGC1A (n=138) genes. PPARG mRNA expression was measured through reverse transcription PCR. Results. The physical exercise intervention resulted in a significant fat mass loss in all participants (40.3±5.3% before the study vs 36.4±5.7% after the study, P<0.00001). Polymorphisms rs6442311, rs6846769, rs6846769 were associated with lower visceral fat percent, rs6442311 also correlated with PPARG expression. PPARGC1A polymorphisms rs4458444, rs2305681 were associated with plasma lipoproteins, cholesterol, and triglyceride content. Weight loss effectiveness was connected with rs17650401, rs9833097, rs12629751. Conclusions. After correction for multiple comparisons only rs17650401, of PPARGC1A gene was associated with more effective fat mass reduction.
