摘要:

目的 探究微小 RNA-223(miR-223)通过调控Kelch 样环氧氯丙烷相关蛋白 1(Keap1)/核因子E2相关因子 2(Nrf2)/抗氧化反应元件(ARE)信号通路对前列腺癌细胞损伤的影响。 方法 培养前列腺癌细胞株PC3,且随机将其分为对照组、下调miR-223组、上调miR-223组。探究miR-223表达、细胞增殖率、细胞迁移数、细胞侵袭数、凋亡率、Keap1/Nrf2/ARE信号通路表达量的变化。 结果 与对照组比较,下调miR-223组的细胞侵袭数、细胞迁移数、24、48、72 h细胞增殖率、Nrf2、ARE表达上升,miR-223、Keap1、凋亡率表达降低(P < 0.05);与下调miR-223组比较,上调miR-223组的24、48、72 h细胞增殖率、细胞侵袭数、细胞迁移数、ARE、Nrf2表达下降,miR-223、凋亡率、Keap1表达升高(P < 0.05)。 结论 调节miR-223可有效改善前列腺细胞损伤,其机制可能与Keap1/Nrf2/ARE信号通路有关。

Abstract:

Objective To investigate the effect of microRNA-223 (miR-223) on prostate cancer cell damage by regulating the Kelch?like epichlorohydrin related protein 1 (Keap1)/nuclear factor E2 related factor 2 (Nrf2)/antioxidant response element (ARE) signaling pathway. Methods The prostate cancer cell line PC3 was cultured and randomly divided into control, down-regulated miR-223, and up-regulated miR-223 groups. Changes in miR-223 expression, cell proliferation rate, cell migration number, cell invasion number, apoptosis rate, and expression level of Keap1/Nrf2/ARE signaling pathway were explored. Results Compared with the control group, the cell invasion number, cell migration number, cell proliferation rate, Nrf2 and ARE expression increased at 24, 48 and 72 h in down-regulated miR-223 group, while the expressions of miR-223, Keap1 and apoptosis rate decreased (P < 0.05). Compared with the down-regulated miR-223 group, 24, 48 and 72 h cell proliferation rate, cell invasion number, cell migration number, ARE and Nrf2 expression decreased in the up-regulated miR-223 group, while miR-223, apoptosis rate and Keap1 expression increased (P < 0.05). Conclusion Regulation of miR-223 effectively ameliorates prostate cell injury, and the mechanism may be related to the Keap1/Nrf2/ARE signaling pathway.
