| 摘 要： | 为观察2-羟基-3-甲基蒽醌(HMA)对结直肠癌细胞增殖的影响并探讨其作用机制,本研究采用CCK8法检测HMA对结直肠癌细胞增殖的影响;Heochst-33343/PI染色检测细胞凋亡情况;同时检测细胞内ROS及GSH含量变化并应用Western blot检测细胞凋亡相关蛋白及Keap-1/Nrf-2/ARE信号途径相关蛋白的表达。实验结果显示,HMA给予结直肠癌细胞后,细胞内ROS含量升高,GSH含量减少;HMA通过抑制Keap-1/Nrf-2/HO-1通路,诱导细胞发生凋亡。综上表明HMA具有抑制结肠癌细胞增殖的作用,其机制可能与破坏细胞内氧化还原平衡,抑制Keap-1/Nrf-2/HO-1通路有关。

| Abstract: | To explore the anti-tumor effect and the possible mechanisms of HMA against colon cancer cells.The CCK8 methods was used to assay the anti-proliferative activity of HMA.The level of intracellular ROS and GSH was measured by commercial kit.Western blot assay was used to detected the protein expression change of Keap-1/Nrf-2/ARE signaling pathway.The results showed that HMA could significantly inhibit the proliferation of colon cancer cells(P<0.05).Compared to the control group,HMA increased the level of ROS while decreased the GSH content,and inhibited the Keap-1/Nrf-2/HO-1 pathway signaling.In conclusion,HMA could significantly inhibit the proliferation of colon cancer cells by disturbing the redox balance,which was related to inhibiting the Keap-1/Nrf-2/HO-1 signaling pathway. |
