摘要:

目的 探讨羽扇豆醇调控miR-100-5p对非小细胞肺癌(NSCLC)NCI-H1299细胞增殖、迁移和侵袭的影响。方法 将体外培养的NCI-H1299细胞分为正常对照(NC)组(未处理)、低剂量组(12.5 μmol/L羽扇豆醇)、中剂量组(25 μmol/L羽扇豆醇)、高剂量组(50 μmol/L羽扇豆醇)、miR-NC组(转染miR-NC)、miR-100-5p组(转染miR-100-5p)、anti-miR-NC+高剂量组(转染anti-miR-NC后用50 μmol/L羽扇豆醇处理)、anti-miR-100-5p+高剂量组(转染anti-miR-100-5p后用50 μmol/L羽扇豆醇处理)。CCK-8和克隆形成实验检测NCI-H1299细胞增殖;Transwell法检测NCI-H1299细胞迁移和侵袭。荧光定量PCR(qPCR)检测miR-100-5p表达;Western blot检测细胞周期蛋白D1(CyclinD1)、基质金属蛋白酶(MMP)2和MMP9蛋白的表达。结果 与NC组比较,低、中、高剂量组NCI-H1299细胞活力、细胞克隆数、迁移数、侵袭数、CyclinD1、MMP2和MMP9蛋白表达降低(P<0.05),miR-100-5p表达逐渐升高(P<0.05)。与miR-NC组比较,miR-100-5p组miR-100-5p表达升高,NCI-H1299细胞活力、细胞克隆数、迁移数、侵袭数、CyclinD1、MMP2和MMP9蛋白表达降低(P<0.05);与anti-miR-NC+高剂量组比较,anti-miR-100-5p+高剂量组miR-100-5p表达下降,NCI-H1299细胞活力、细胞克隆数、迁移数、侵袭数、CyclinD1、MMP2和MMP9蛋白表达升高(P<0.05)。结论 羽扇豆醇通过上调miR-100-5p表达抑制NSCLC细胞NCI-H1299增殖、迁移和侵袭。

Abstract:

Objective To investigate the effect of lupeol on the proliferation, migration and invasion of non-small cell lung cancer (NSCLC) NCI-H1299 cells by regulating miR-100-5p. Methods NCI-H1299 cells cultured in vitro were divided into the normal control (NC) group (untreated), the low-dose group (12.5 μmol/L lupeol), the medium-dose group (25 μmol/L lupeol), the high-dose group (50 μmol/L lupeol), the miR-NC group (transfected with miR-NC), the miR-100-5p group (transfected with miR-100-5p), the anti-miR-NC+high-dose group (the cells were treated with 50 μmol/L lupeol after transfected with anti-miR-NC), and the anti-miR-100-5p+high-dose group (the cells were treated with 50 μmol/L lupeol after transfected with anti-miR-100-5p). CCK-8 and colony formation assays were performed to evaluate the proliferation of NCI-H1299 cells. Transwell method was applied to detect the migration and invasion of NCI-H1299 cells. RT-qPCR was used to detect the expression of miR-100-5p. Western blot assay was used to detect the expression of CyclinD1, matrix metalloproteinase 2 (MMP2) and matrix metalloproteinase 9 (MMP9) proteins. Results Compared with the NC group, NCI-H1299 cell viability, colony formation number, migration number, invasion number, the expression levels of CyclinD1, MMP2 and MMP9 proteins were decreased in the low, medium and high dose groups (P<0.05), and the expression of miR-100-5p was significantly increased (P<0.05). Compared with the miR-NC group, the expression of miR-100-5p was increased, the NCI-H1299 cell viability, colony formation number, migration number, invasion number, the expression of CyclinD1, MMP2 and MMP9 proteins decreased in the miR-100-5p group (P<0.05). Compared with the anti-miR-NC+ high-dose group, the expression of miR-100-5p was decreased, NCI-H1299 cell viability, colony formation number, migration number, invasion number, the expression of CyclinD1, MMP2 and MMP9 proteins increased in the anti-miR-100-5p+ high-dose group (P<0.05). Conclusion Lupeol inhibits the proliferation, migration and invasion of NSCLC cells NCI-H1299 by up-regulating miR-100-5p.
