| Abstract: | Both endothelial lipase gene(LIPG)584C>T (rs2000813)polymorphism and alcohol consumption modulate serum lipid levels.But their interactions on serum lipid profiles are not well known.The present study was undertaken to detect the interactions of LIPG 584C>T polymorphism and alcohol consumption on serum lipid levels.Genotyping of the LIPG 584C>T was performed in 763 nondrinkers and 520 drinkers aged 15-85.Interactions between the genotypes and alcohol consumption were assessed by using a cross-product term.The levels of serum total cholesterol(TC),triglyceride (TG),high-density lipoprotein cholesterol(HDL-C),apolipoprotein (Apo) AI,and the ratio of ApoAI to ApoB were higher in drinkers than in nondrinkers(P<0.01 for all).There was no significant difference in the genotypic and allelic frequencies between nondrinkers and drinkers.The levels of serum TC, HDL-C and ApoAI in nondrinkers were different among the three genotypes(P<.05-.01).The subjects with CT genotype had higher serum TC,HDL-C and ApoAI levels than the subjects with CC genotype.The levels of serum HDL-C and ApoAI in drinkers were different among the three genotypes (P<.001 and P<.05;respectively).The individuals with TT genotype had higher serum HDL-C and ApoAI levels than the individuals with CC and CT genotypes.The levels of TC in nondrinkers were correlated with LIPG 584C>T allele (P<.05),whereas the levels of TG and HDL-C were associated with LIPG 584C>T alleles(P<.05) and genotypes (P<.05);respectively.The present study suggests that the subjects with TT genotype benefited more from alcohol consumption than the subjects with CT and TT genotypes in increasing serum HDL-C and ApoAI levels. |
