摘要 目的:探讨地塞米松(DXT)对马兜铃酸(aristolochic acid,AA)诱导的人近端肾小管上皮细胞凋亡的影响及其可能机制。方法:应用不同浓度DXT处理经AA诱导的近端肾小管上皮细胞株(HK-2细胞)48h;应用Hoechst33258染色法和流式细胞技术检测HK-2细胞凋亡百分率;应用RT-PCR法测细胞Caspase-3 mRNA的表达;应用分光光度法测细胞Caspase-3酶活性。结果:40μg/mlAA可显著促进HK-2细胞凋亡,DXT可显著降低AA诱导的HK-2细胞凋亡百分率,并呈剂量依赖趋势;各组细胞Caspase-3mRNA表达水平无统计学差异;40μg/mlAA可显著升高HK-2细胞Caspase-3酶活性;而100MDXT组细胞Caspase-3酶活性较单纯40μg/mlAA刺激显著降低,而其他浓度DXT组细胞Caspase-3活性与单纯AA比较无统计学差异。结论:DXT对AA所致HK-2细胞凋亡有一定的保护作用,其机制可能是抑制细胞凋亡过程中Capease-3酶的激活。
