Abstract:
Introduction: The metabolic syndrome (MS) is characterized by central obesity, hypertriglyceridemia,low high-density lipoprotein (HDL), increase blood pressure and raise fasting plasma glucose. ThePGC-1α gene is located on chromosome 4 p.15.1 in humans and encodes a protein containing 798amino acids. The protein encoded by this gene is a transcriptional coactivator that regulates thegenes involved in energy metabolism. PPARγ, a coactivator molecule recently identified based on itsability to interact with PPARγ, is involved in many important metabolic processes, including adaptivethermogenesis, mitochondrial biogenesis and fatty acid β–oxidation.Goal: To study the frequency of PGC-1α Gly482Ser polymorphism in people with MS in relation to therisk factors of the MS.Materials and methods: The study population comprised 302 unrelated Mongolian subjects (158 withmetabolic syndrome and 144 controls). The genotypes for polymorphism of candidate gene related toMS were determined using a RFLP analysis of the MspI digest of the PCR product.Result: From the control group, 33.4% (48) had GG, 47.2% (68) had GS and 19.4% (28) had SSgenotypes. 51.9% (82) of people with MS had GG, 35.4% (56) had GS and 12.7% (20) had SSgenotypes. The prevalence of G allele in people with MS was 69.6%, which is much higher than healthygroup. Comparing PGC-1α Gly482Ser GG, GS and SS genotypes with systolic arterial blood pressurerevealed statistically significant difference which was higher among subjects with GG genotype. Theblood pressure of people with MS and carrying GG genotype of PGC-1α Gly482Ser polymorphismwas significantly increased 2.35 times than people without MS.Conclusions:1. 69.6 percentages of the people with MS had G allele and 2.2 times more than those withoutmetabolic syndrome.2. We determined that the odds ratio for the high blood pressure and it was 2.35 times higher inpeople with GG allele of Gly482Ser carriers than GS and SS alleles carriers (OR = 2.35, p =0.012).
