Abstract:
The effects of catalpol on lung cancer cell proliferation, apoptosis, migration, and oxidative stress via the Nrf2/ARE signaling pathway are investigated in this work. Catalpol-12 g/mL group, catalpol-24 g/mL group, catalpol-48 g/mL group, catalpol − 48 g / mL + vector group , catalpol − 48 g / mL + Nrf 2 group , si-NC group, and si-Nrf2 group were used to split lung cancer cells A549 into control groups. Proliferation was detected using the CCK-8 assay; apoptosis was detected using flow cytometry; migration was detected using the transwell chamber; ROS was distinguished using the DCFHDA method; MDA, SOD, and GSH were detected using the microvolume method; and Cleaved Caspase-3, Cleaved Caspase-9, Nrf2, HO-1, MMP-9, and MMP-2 were detected using the Western blot method. Catalpol 12 g/mL and 24 g/mL-48 g/mL treatment decreased the proliferation activity, migration number, and Nrf2, HO-1, MMP-9, and MMP-2 protein levels of lung cancer cells when compared to the control group. SOD and GSH levels of lung cancer cells were decreased, and MDA and ROS levels were increased. Cleaved caspase-3, cleaved caspase-9 protein expression levels, and apoptosis were boosted ( P 〈 0.05 ). The proliferation activity, migration number, and protein levels of Nrf2, HO-1, MMP-9, and MMP-2 in the catalpol − 48 g / mL + Nrf 2 group were raised compared to the catalpol − 48 g / mL + vector group , whereas there was an apparent drop in the Cleaved Caspase-3, Cleaved Caspase-9, and apoptosis rate. Similarly, SOD and GSH contents increased, whereas MDA and ROS decreased ( P 〈 0.05 ). The proliferation activity, migration number, and Nrf2, HO-1, MMP-9, and MMP-2 protein levels of lung cancer cells in the si-Nrf2 group were all decreased when compared to the si-NC and control groups. Cleaved Caspase-3 and Cleaved Caspase-9 protein expression, on the other hand, increased as MDA and ROS levels were raised while SOD and GSH levels dropped ( P 〈 0.05 ). It reveals that catalpol inhibits the Nrf2/ARE signaling pathway, which causes antiproliferation, migration, apoptosis, and oxidative stress in cancer cells of lungs. The rate of apoptosis was also lowered.
