摘要: 目的 探讨Ghrelin基因多态性与2型糖尿病之间的关系。方法 进行Ghrelin基因C408A和G346A的多态性分析,同时进行生化指标和临床参数的检测。结果 正常对照组(NGT组)C408A基因型CC、CA、AA的基因型频率分别为75.4%、24.0%及0.6%。2型糖尿病组(DM组)中CC、CA及AA的基因型频率分别为70.8%、28.2%及1.0%。NGT组CC基因型者总胆固醇水平明显高于CA+AA基因型者;DM组CC基因型者血尿酸水平明显高于CA+AA基因型者。在所有的受试者中未发现G346A 多态性存在。结论 Ghrelin基因C408A分布与等位基因频率没有明显的差异;本组人群中未发现Ghrelin G346A 多态性存在;C408A多态性与总胆固醇和尿酸水平相关。

Abstract: Objective To study relationship between ghrelin gene polymorphisms and type 2 diabetes and its risk factors.Methods All subjects were genotyped for these two single nucleotide polymorphisms (C408A, G346A) of ghrelin by PCR-RFLP assay. Anthropometric variables, blood glucose, insulin, lipid, uric acid and other clinic parameters were measured.Result In control group, the genotype frequencies as follows: CC 75.4%(n=251), CA 24%(n=80), and AA 0.6%(n=2). In type 2 diabetes group, the genotype frequencies: CC 70.8%(n=143), CA 28.2%(n=57), and AA 1.0(n=2). There were no significant differences of the genotype frequencies in two groups. In control group, serum total cholesterol in subjects carrying CC genotype is higher than subjects not carrying CC genotype ((P<0.05); in type 2 diabetes groups, serum uric acid in subjects carrying CC genotype is higher than subjects not carrying CC genotype ((P<0.05).There were not G346A variants existed in our study subjects.Conclusion The allele frequencies and genotype distribution of the C408A did not differ significantly among control and type 2 diabetes groups; G346A polymorphisms were not existed in control and type 2 diabetes groups. C408A variants associated with total cholesterol and uric acid.
