脂多糖对人肠微血管内皮细胞水通道

蛋白1表达及功能的影响

陈信浩 纪俊标 吕纯业 戴存才

【摘要】 目的 研究脂多糖(LPS)对人肠微血管内皮细胞(HIMEC)水通道蛋白(AQP)1表达及功能的影响。方法 40份HIMEC均分为A、B、C、D四组。A、B、C组分别经浓度为0.1、1、10mg/L的LPS作用;D组为对照组,只加培养基。各组细胞培养12h。Western blot法检测HIMEC AQP-1的表达;RT-PCR检测HIMEC AQP-1mRNA的表达;放射法测定HIMEC的摄水功能。结果 随着作用于HIMEC的LPS浓度增加,AQP-1蛋白及其mRNA表达和HIMEC的摄水功能均逐步减少(P<0.05)。结论 HIMEC AQP-1表达与LPS浓度呈负性相关。

【Abstract】 Objective To study the effects of lipopolysaccharide(LPS)on aquaporin 1(AQP-1)expression and function in human intestinal microvascular endothelial cells(HIMEC).MethodsFourty pieces of HIMEC were equally randomized into 4groups of A(treated with LPS 0.1mg/L for12h),B(with LPS 1mg/L),C(with LPS 10mg/L)and D(blank control).The expressions of AQP-1protein and mRNA in HIMEC were detected by Western blot and RT-PCR,respectively.Water intakeof HIMEC was measured by radioactive method.Results As the concentration of LPS increased,theexpressions of AQP-1protein and mRNA in HIMEC were decreased(P<0.05).So did the ability ofwater intake of HIMEC(P<0.05).Conclusion AQP-1expression is negatively correlated to LPSconcentration.
