The association of Pro12Ala polymorphism in the peroxisome proliferator-activated receptor-gamma2 gene with the metabolic characteristics in Chinese women with polycystic ovary syndrome.

ABSTRACT: BACKGROUND: The Pro12Ala polymorphism in the peroxisome Proliferator-activated receptor-gamma2 PPAR?2) gene that account for metabolic dysfunction in women with polycystic ovary syndrome (PCOS) remain elusive. AIM: To explore the association between PPAR?2 gene pro12ala polymorphism and the metabolic characteristics in Chinese women with PCOS. METHODS: PPAR?2 gene Pro12Ala polymorphism was assayed by PCR/RFLP methods in 120 Chinese women with PCOS and 118 normal subjects. All subjects were examined by anthropometry, lipid profile, sex hormone, oral glucose tolerance tests and insulin tolerance tests. RESULTS: In PCOS patients, women with the non-Pro/Pro genotypes of the PPAR?2 gene Pro12Ala polymorphism showed statistically significantly higher fasting triglycerides (TG) levels and WHR value than those with the Pro/Pro genotype (P=.006 for both). There was no significant difference with PPAR?2 Pro12Ala polymorphism distributions between Chinese Han women with PCOS and controls. CONCLUSION: PPAR?2 gene Pro12Ala polymorphism was not supposed to be susceptible genes in PCOS. However, in PCOS patients, the PPAR-gamma Pro12Ala polymorphism may modulate the concentrations of serum fasting TG levels and fat-deposition in abdomen, respectively.

Project description:IntroductionPrematurity is the leading cause of death and disability in children under 5 years of age. Understanding the molecular mechanisms of the biological processes involved in preterm brain injury may help develop novel neuroprotective treatment strategies. A growing body of evidence suggest that peroxisome proliferator-activated receptor gamma (PPARγ) signaling is associated with inhibited brain development in preterm babies. The Ala allele of the Pro12Ala polymorphism of PPARγ2 decreases receptor binding affinity and consequently induces a reduction of PPARγ signaling.MethodsIn this study, we carried out a preliminary analysis of existing datasets to test the hypothesis that reduced transactivation capacity of PPARγ in the presence of the Ala variant of PPARγ2 may be associated with adverse neurodevelopment in preterm babies. The association between PPAR-γ2 Pro12Ala polymorphism and neurodevelopment at 18-24 months of age was assessed in two groups of European infants, 155 born before 33 weeks' gestation and 180 born later than 36 weeks' gestation using a linear regression model. The Bayley Scales of Infant and Toddler Development-3rd edition was administered to assess neurodevelopment at 18-24 months of age.ResultsWe observed the Ala allele of the Pro12Ala polymorphism in 25% preterm infants and 20% term infants. The Ala allele of PPARγ2 was significantly associated with adverse cognitive (p = .019), language (p = .03), and motor development (p = 0.036) at 18-24 months of age after taking into consideration the duration of ventilation, gender, and index of multiple deprivation scores, but without correction for potential shared ancestry. There was no association between the PPAR-γ2 Pro12Ala polymorphism and neurodevelopment in term infants.ConclusionsThese preliminary data suggest that PPARγ signaling in the presence of the Ala variant of PPARγ2 may be associated with adverse neurodevelopment in preterm infants suggesting that further studies are warranted.
