异鼠李素抑制耐吉非替尼人肺癌细胞PC9增殖的研究
Isorhamnetin Suppresses the Growth of Gefitinib Resistant Human Lung Cancer PC9 Cells
摘要
Abstract
Objective To investigate the role of isorhamnetin on the growth of PC9-IR cells. Methods The gefitinib-resistant PC9(PC9-1R) cells were generated by consistently culturing the PC9 cells with 10% FBS/DMEM contained 0.5 μmol·L-1 gefitinib. Then, the PC9-1R cells were treated with isorhamnetin at different concentrations. The proliferation was detected by MTT assay after 24,48 and 72 h, respectively, with PBMNCs as control. Western blot assay was used to detect the change of growth signal pathway. Additionally, clonal assay was performed to analyze the clone formation ability of PC9-IR with or without isorhamnetin. Results Isorhamnetin inhibitted the growth of PC9-1R. The IC50 at the three time points were 212 μmol·L-1 (24 h) ,98 μmol·L-1(48 h) ,64 μmol·L-1(72 h) ,and PBMNCs was 204 μmol·L-1(72 h). It was showed thai the phosph-Akt was suppressed and the clonal formation ability of PC9-IR was lowered by isorhamnetin. Conclusion Isorhmantin could inhibit the growth of PC9-IR cells through suppressing the phosphorylation of Akt.关键词
