摘要: 目的 探讨miR-144-3p对Ang Ⅱ诱导的人脐静脉内皮细胞(HUVEC)增殖、侵袭、凋亡和ROS水平的影响。方法 将细胞分为对照组(control)、模型组(Ang Ⅱ)、阴性对照组(Ang Ⅱ+转染miR-144-3p NC)和实验组(Ang Ⅱ+转染miR-144-3p mimic)。PCR验证转染效率;MTT法检测细胞增殖;Transwell小室法检测细胞侵袭;凋亡试剂盒和流式细胞测量术检测细胞凋亡;流式细胞测量术检测细胞内活性氧(ROS)水平。结果 与对照组相比,模型组细胞的增殖和侵袭能力显著下降,而凋亡率和细胞内ROS水平显著上升(P<0.05);而实验组细胞上述指标均可得到一定程度的缓解(P<0.05)。结论 过表达miR-144-3p能够有效减轻由Ang Ⅱ诱导的HUVEC增殖、侵袭能力,以及降低Ang Ⅱ诱导的HUVEC细胞凋亡率和ROS水平。

Abstract: Objective To investigate the effect of miR-144-3p on the proliferation, invasion, apoptosis and ROS levels of human umbilical vein endothelial cell (HUVEC) induced by angiotensin Ⅱ(Ang Ⅱ). Methods The cells were divided into control group, model group (Ang Ⅱ), negative control group (Ang Ⅱ+ transfection miR-144-3p NC) and experimental group (Ang Ⅱ + transfection miR-144-3p mimic). RT-qPCR was used to detect the transfection efficiency. MTT method was used to detect cell proliferation. Cell invasion was examined by Transwell chamber. Apoptosis kit and flow cytometry were applied to detect apoptosis, and the flow cytometry was applied to detect intracellular reactive oxygen species(ROS) level. Results Compared with control group, the proliferation and invasion of the cells in the model group decreased significantly, but the apoptotic rate and intracellular ROS level increased significantly(P<0.05). The above indicators found in the experimental group were all alleviated to a certain extent (P<0.05). Conclusions Over-expression of miR-144-3p can effectively reduce the proliferation and invasion of HUVEC induced by Ang Ⅱ and reduce the apoptosis rate as well as ROS level.
