摘要: 目的 在原来研究的基础上进一步研究Wnt-1信号通路蛋白-3(WISP-3)在高氧诱导肺上皮细胞凋亡中的作用。方法 通过Western blot检测和免疫组化检测不同肺上皮细胞中WISP-3的蛋白表达量。利用质粒转染和siRNA的方法在Beas-2B细胞中高表达和基因沉默WISP-3,通过细胞活性检测和流式细胞学技术检测高氧刺激后细胞的凋亡情况。结果 与空气对照相比,高氧刺激使肺上皮细胞的WISP-3蛋白表达量下降;WISP-3基因沉默或高表达使高氧诱导的肺上皮细胞凋亡增加或减少。结论 高氧刺激下,肺上皮细胞中WISP-3表达下降,WISP-3对高氧诱导的肺上皮细胞凋亡具有保护作用。

Abstract: Objective To explore how Wnt-1 inducible signaling pathway protein-3 (WISP-3) participate in and play a regulatory role in the process of hyperoxia induced apoptosis in lung epithelial cells. Methods The expression of WISP-3 was detected via Western blot and immunohistochemistry. High expression and low expression of WISP-3 were performed by plasmid transfection and siRNA. Cell viability and flow cytometry were executed to detect the hyperoxia-induced apoptosis in Beas-2B. Results Compared to the group of air control,the expression of WISP-3 protein in lung epithelial cells decreased obviously after hyperoxia. Cell survival decrease and apoptosis increased after hyperoxia in Beas-2B cells with low expression of WISP-3. Vice versa. Conclusion The expression of WISP-3 decreased after hyperoxia in lung epithelial cells. The role of WISP-3 in this process may be protective.
