Ассоциация ОНП Pro12Ala (rs1801282) гена PPARG с уровнем мРНК в интраабдоминальной жировой ткани у женщин

Obesity is considered to be a rapidly growing health problem worldwide. The factors that regulate body fat content and distribution are not fully understood. Our study aimed to investigate whether the Pro12Ala (rs1801282) polymorphism of the PPARG gene may influence on PPARG expression in visceral adipose tissue in fertile women in Russia. The study included 27 women without type 2 diabetes mellitus and cardiovascular dysfunction (mean age 43.00 (30.00-49.00), BMI 28.73 (18.13-56.18) kg/m 2 ). Genotyping of the Pro12Ala PPARG polymorphisms were determined by PCR-RFLP assay. PPARG expression were estimated by RT-PCR with TaqMan probes. Our results demonstrated that mRNA PPARG level was significantly lower in subjects with the 12Ala allele (AlaAla+AlaPro) than in ProPro genotype carriers (p = 0,029). In conclusion, we demonstrate that the Pro12Ala PPARG polymorphism may influence to the observed variability in PPARG expression in visceral adipose tissue and thereby contribute to the pathogenesis of abdominal obesity in fertile women.
