淋巴细胞中pot1 mrna表达?端粒酶活性与2型糖尿病发生发展的关系

目的:研究淋巴细胞中端粒保护蛋白(POT1)的表达、端粒酶活性与2型糖尿病发生发展的关系。方法:以2型糖尿病患者162例为实验组,以健康体检者162例为对照组,RT-PCR检测POT1mRNA的表达;TRAP-ELISA分析端粒酶活性。结果:实验组POT1 mRNA的表达和端粒酶活性均明显高于对照组。其中血糖控制尚可组和差组分别与对照组比较,POT1 mRNA表达和端粒酶活性均明显增高;按糖尿病性视网膜病变分期中各组POT1mRNA表达和端粒酶活性与对照组比较存在显著性差异;且病程5～10年组、10年以上组与5年以下组相比,POT1mRNA表达和端粒酶活性也存在显著性差异。结论:2型糖尿病淋巴细胞中POT1mRNA的表达和端粒酶活性均明显增高,且与病情发展呈正相关。POT1和端粒酶的表达变化作为预后的评价依据有重要的临床意义。

relationship of pot1 mrna expression,telomerase activity and development of type 2 diabetes

Objective:To study the relationship of protection of telomeres 1(POT1) mRNA expression,telomerase activity in lymphocytes with the development of type 2 diabetic mellitus(T2DM).Methods:One hundred and sixty-two cases with T2DM were test group,162 cases of healthy were control group,real-time quantitative PCR was used to analysis POT1 mRNA expression,semi-quantitative TRAP-ELISA was used to analysis telomerase activity.Results:The expression of POT1 mRNA and telomerase relatively activity in test group were ...
