Effect of BCHE single nucleotide polymorphisms on lipid metabolism markers in women.

ABSTRACT: Butyrylcholinesterase (BChE) activity and polymorphisms in its encoding gene had previously been associated with metabolic traits of obesity. This study investigated the association of three single nucleotide polymorphisms (SNPs) in the BCHE gene: -116G > A (rs1126680), 1615GA (rs1803274), 1914A < G (rs3495), with obesity and lipid metabolism markers, body mass index (BMI), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), triglyceride (TG) levels, and BChE enzymatic activity in obese (BMI?30/n = 226) and non-obese women (BMI < 25/n = 81). BCHE SNPs genotyping was obtained by TaqMan allelic discrimination assay and by RFLP-PCR. Plasmatic BChE activity was measured using propionylthiocholine as substrate. Similar allele frequencies were found in obese and non-obese women for the three studied SNPs (p > 0.05). The dominant and recessive models were tested, and different effects were found. The -116A allele showed a dominant effect in BChE activity reduction in both non-obese and obese women (p = 0.045 and p < 0.001, respectively). The 1914A > G and 1615GA SNPs influenced the TG levels only in obese women. The 1914G and the 1615A alleles were associated with decreased plasma levels of TG. Thus, our results suggest that the obesity condition, characterized by loss of energy homeostasis, is modulated by BCHE polymorphisms.

Project description:This retrospective study aims to identify the single nucleotide polymorphisms (SNPs) of 5,10-methylenetetrahydrofolate reductase (MTHFR) (C677T, A1298C), methionine synthase reductase (MTRR) (A66G) and ethnic distribution characteristics in pregnant women, and to explore the risk correlation with folate metabolism. The demographic data of 8735 pregnant women aged 15 to 47 years were retrospectively analyzed, and peripheral blood samples were collected and tested. Reverse transcription-quantitative polymerase chain reaction was applied to determine the genotype and allele frequency of MTHFR C677T, A1298C and MTRR A66G in blood samples. Sperman correlation analysis, univariate and multivariate logistic regression analysis were used to verify the correlation between SNPs of MTHFR (C677T, A1298C), MTRR (A66G), different ethnic groups and the susceptibility and risk levels of folate metabolism. The relative risk of the SNPs was further determined by calculating the odds ratio (OR) at a 95% confidence interval (CI). The average age of 8735 pregnant women was 28.87 ± 4.20 years old. The evaluation of risk levels for folate metabolism was relative high, including 2296 cases with low risk, 3971 cases with medium risk, and 752 cases with high risk. Among the MTHFR C677T locus, the CC genotype had the highest frequency, MTHFR A1298C locus had the highest frequency of the AA genotype, and MTRR A66G locus had the highest frequency of the AA genotype. The frequency distribution of SNPs in different ethnic groups revealed that the frequency of CT genotype among the MTHFR C677T locus, AA genotype among the MTHFR A1298C locus and the MTRR A66G locus was the highest in Han, Buyi, Miao and Dong ethnic groups. The results of logistic regression analysis showed that the Han, Buyi, Miao and other ethnic groups (including Yi, Bai, Zhuang, Chuanqing) had the possibility of increasing the risk levels of folate metabolism. The CC genotype of MTHFR C677T (adjusted OR = 2.46, 95% CI: 2.14-2.84, P < .001) and the AG genotype of MTRR A66G (adjusted OR = 1.89, 95% CI: 1.61-2.22, P < .001) were significantly related to the risk levels of folate metabolism, which is an independent risk factor for the susceptibility of folate metabolism.
