摘要: 目的:研究Delicaflavone对人吉非替尼耐药肺癌PC-9/GR细胞迁移与侵袭作用及机制。方法:采用MTT法检测Delicaflavone对PC-9/GR细胞存活率的影响;采用细胞划痕实验和Transwell实验测定Delicaflavone对PC-9/GR细胞迁移和侵袭能力的影响;采用Western blotting法检测Delicaflavone对PC-9/GR细胞基质金属蛋白酶9(matrix metalloproteinases 9, MMP-9)、基质金属蛋白酶2(matrix metalloproteinases 2, MMP-2)、钙黏连蛋白(E-cadherin, N-cadherin)、波形蛋白(vimentin)及PI3K/Akt/mTOR信号通路相关蛋白表达情况。结果:与对照组比较,20 mg/L Delicaflavone作用24 h能显著抑制PC-9/GR细胞的细胞活性(P<0.05),而浓度在10 mg/L以下时则对细胞活性无明显影响。Delicaflavone能够浓度依赖性地抑制PC-9/GR细胞的迁移率、侵袭细胞数量(P<0.05和P<0.01),并能浓度依赖性地减少PC-9/GR细胞迁移标记蛋白(MMP-9和MMP-2)的表达(P<0.01),上调E-cadherin、下调N-cadherin和Vimentin的表达(P<0.01)。此外,Delicaflavone还浓度依赖性地减少p-PI3K、p-Akt和p-mTOR表达(P<0.01)。 结论:Delicaflavone具有抑制PC-9/GR细胞迁移及侵袭能力的作用,该作用与Delicaflavone通过PI3K/Akt/mTOR通路调控上皮-间质转化有关。

Abstract: AIM: To study the effect and mechanism of Delicaflavone on migration and invasion of gefitinib-resistant lung cancer cell line PC-9/GR.  METHODS: MTT assay was used to detect cell viability. Transwell and scratch assays were used to detect cell invasion and migration abilities. Western blotting was used to detect the expressions of MMP-9, MMP-2, E-cadherin, N-cadherin, Vimentin and PI3K/Akt/mTOR pathway-related proteins in PC-9/GR cells. RESULTS: Compared with control group, 20 mg/L Delicaflavone could significantly inhibit the viability of PC-9/GR cells for 24 h (P<0.05), while Delicaflavone below 10 mg/L had no significant effect on cell proliferation. The number of invasive cells and migrated cells were decreased significantly by Delicaflavone in a concentration-dependent way (P<0.05 and P<0.01). Delicaflavone could concentration-dependently reduce the expression of MMP-9, MMP-2, N-cadherin, vimentin (P<0.01), meanwhile up-regulate the expression of E-cadherin (P<0.01). In addition, Delicaflavone also decreased the expression of p-PI3K, p-Akt and p-mTOR in a concentration-dependent manner (P<0.01). CONCLUSION: Delicaflavone can inhibit the migration and invasion of PC-9/GR cells by regulating epithelial-mesenchymal transition via PI3K/Akt/mTOR pathway.
