异莲心碱调节NF-κB/AP-1信号通路对结直肠癌细胞增殖迁移侵袭及凋亡的影响OA
Effects of Isoleucine on the Proliferation Migration Invasion and Apoptosis of Colorectal Cancer Cells by Modulating the NF-κB/AP-1 Signaling Pathway
目的:探讨异莲心碱(ISO)调节核因子κB(NF-κB)/激活蛋白1(AP-1)信号通路对结直肠癌(CRC)细胞增殖、迁移、侵袭及凋亡的影响.方法:将Caco2 细胞随机分为Control组(正常培养)、L-ISO组、M-ISO组、H-ISO组(分别加入 10、20、40μmoL/L 的 ISO);ISO+PMA 组[40μmoL/L 的 ISO+1 μmoL/L的NF-κB 信号通路激活剂佛波酯(PMA)].EdU 染色 Caco2 细胞增殖;划痕实验检测 Caco2细胞迁移;Transwell实验检测Caco2 细胞侵袭;流式细胞仪检测Caco2 细胞细胞凋亡;WB 检测各组Ca-co2 细胞中NF-κB、AP-1 蛋白的表达.结果:L-ISO、M-ISO、H-ISO 组 EdU 阳性细胞率、划痕愈合率、侵袭数、NF-κB、AP-1 蛋白表达低于Control组,凋亡率高于Control组(P<0.05);ISO+PMA组细胞EdU阳性细胞率、划痕愈合率、侵袭数、NF-κB、AP-1 蛋白表达高于H-ISO组,凋亡率低于H-ISO组(P<0.05).结论:ISO可以抑制NF-κB/AP-1 信号通路,进而抑制CRC 细胞的增殖、迁移、侵袭,促进细胞凋亡.
Objective:To investigate the impacts of isoliensinine(ISO)on the proliferation,migration,invasion,and apoptosis of colorectal cancer(CRC)cells by modulating nuclear factor-κB(NF-κB)/activa-tor protein 1(AP-1)signaling pathway.Methods:Caco2 cells were assigned into Control group(normal culture),L-ISO group,M-ISO group,and H-ISO group(added with 10,20,and 40μmol/L ISO,respec-tively);ISO+PMA group[40μmol/L ISO+1μmol/L NF-κB signaling pathway activator phorbol ester(PMA)]randomly.EdU staining was used to measure Caco2 cell proliferation.Scratch assay was applied to measure Caco2 cell migration.Transwell experiment was used to detect Caco2 cell invasion.Flow cytometry was applied to measure apoptosis of Caco2 cells.WB was used to test NF-κB and AP-1 proteins in various groups.Results:The L-ISO,M-ISO,and H-ISO groups had lower EdU positive cell rate,scratch healing rate,invasion number,NF-κB,and AP-1 proteins,and higher apoptosis rate than Control group(P<0.05).The ISO+PMA group had higher EdU positive cell rate,scratch healing rate,invasion number,NF-κB,and AP-1 proteins,and lower apoptosis rate than H-ISO group(P<0.05).Conclusion:ISO can in-hibit the NF-κB/AP-1 signaling pathway,thereby suppressing the proliferation,migration,and invasion of CRC cells and promoting cell apoptosis.
