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.
