摘要 目的了解外周血白细胞(WBC)中SIRT1、SIRT4与2型糖尿病(T2DM)的相关性,及其能否作为检测指标用于反映T2DM患者的血糖、血脂水平以及胰岛β细胞功能。方法收集对照组(NC组)与T2DM组的资料,用免疫细胞化学染色检测SIRT1、SIRT4在WBC(包括粒细胞、单核细胞、淋巴细胞)中的表达情况,用逆转录聚合酶链式反应(RT-PCR)检测WBC中SIRT1、SIRT4的相对mRNA水平。结果免疫细胞化学染色结果显示SIRT1在粒细胞、单核细胞的胞核和胞浆中都有表达,而SIRT4主要在这两种细胞的胞浆中表达,但SIRT1、SIRT4在淋巴细胞中表达不明显。RT-PCR结果显示,T2DM组SIRT1、SIRT4 mRNA水平显著低于NC组(P<0.01)。相关分析结果显示WBC中SIRT1、SIRT4表达与T2DM及其血糖、血脂相关。结论 SIRT1、SIRT4在WBC中有表达,WBC中SIRT1、SIRT4表达也许可以间接反映胰岛β细胞功能,并且与T2DM之间可能存在关系。
