[Retracted] The Impact of Catalpol on Proliferation, Apoptosis, Migration, and Oxidative Stress of Lung Cancer Cells Based on Nrf2/ARE Signaling

Figure 5

The proliferation activity, apoptosis rate, migration number, and protein expression levels. The proliferation activity, apoptosis rate, migration number, and expression levels of protein of Nrf2, HO-1, MMP-9, MMP-2, Cleaved Caspase-3, and Cleaved Caspase-9 in lung cancer cells are transfected with Nrf2 overexpression vector and treated with catalpol. (a) Changes in lung cancer cell proliferation activity (OD value). (b) Detection of lung cancer cell apoptosis changes by flow cytometry. (c) Detection of lung cancer cell migration by transwell chamber (200×). (d) Detection of Nrf2, HO-1, MMP-9, MMP-2, Cleaved Caspase-3, and Cleaved Caspase-9 protein expression in lung cancer cells by western blot; compared with the control group, ; compared with catalpol-12 μg/mL group, ^#; compared with catalpol-24 μg/mL group, ^&; compared with , ^△.
