摘要: 目的 探讨花姜酮对非小细胞肺癌细胞系增殖、迁移和侵袭的影响及其潜在机制。方法 将人非小细胞肺癌细胞系A549分为对照组、花姜酮-低剂量组、花姜酮-中剂量组、花姜酮-高剂量组、pcDNA组、pcDNA-FBXW7组、花姜酮-高剂量+si-NC组、花姜酮-高剂量+si-FBXW7组。四甲基偶氮唑蓝(MTT)法检测细胞增殖抑制率,Transwell小室法检测细胞迁移和侵袭,RT-qPCR和Western blot检测F-BOX家族F框/WD-40域蛋白7(FBXW7)mRNA和蛋白的表达。结果 与对照组比较,花姜酮-低、中、高剂量组A549细胞增殖、迁移和侵袭能力显著降低(P<0.05),FBXW7 mRNA和蛋白表达显著升高(P<0.05)。与pcDNA组比较,pcDNA-FBXW7组A549细胞增殖、迁移和侵袭能力显著降低(P<0.05)。与花姜酮-高剂量+si-NC组比较,花姜酮-高剂量+si-FBXW7组A549细胞系增殖、迁移和侵袭能力显著升高(P<0.05)。结论 花姜酮可降低非小细胞肺癌细胞系的增殖、迁移和侵袭能力,其机制与上调FBXW7表达有关。

Abstract: Objective To explore the effect of zerumbone on proliferation, migration and invasion of non-small cell lung cancer cell line and underline mechanism. Methods Human non-small cell lung cancer cells line A549 was divided into control group, zingerone-low dose group, zingerone-medium dose group, zingerone-high dose group, pcDNA group, pcDNA-FBXW7 group, and zingerone-high dose group +si-NC group, zingerone-high dose +si-FBXW7 group. Cell proliferation inhibition was detected by methyl thiazolyl tetrazolium (MTT) method, cell migration and invasion were detected by Transwell assays, and the expression of F-box with 7 tandem WD40 (FBXW7) mRNA and protein were detected by Western blot and real-time(RT-qPCR). Results Compared with control group, the proliferation, migration and invasion of A549 cells in the zingerone-low, medium and high dose groups were significantly reduced (P<0.05), the expression of FBXW7 mRNA and protein were significantly increased (P<0.05). Compared with the pcDNA group, the proliferation, migration and invasion of A549 cells in the pcDNA-FBXW7 group were significantly reduced (P<0.05). Compared with the Zingerone-high-dose+si-NC group, the cell proliferation, migration and invasion ability of A549 in the Zingerone-high-dose+si-FBXW7 group was significantly increased (P<0.05). Conclusions Zerumbone reduces proliferation, migration and invasion of non-small cell lung cancer cells, and the underlying mechanism is related to the up-regulation of FBXW7 expression.
