Abstract:
Background: Lung cancer is one of the more common malignant tumors posing a great threat to human
life, and it is very urgent to find safe and effective therapeutic drugs. The antitumor effect of ginsenosides has
been reported to be a treatment with a strong effect and a high safety profile.
Objective: This paper aimed to investigate the inhibitory effect of ginsenoside Rb1 on 95D and NCI-H460 lung
cancer cells and its pathway to promote apoptosis.
Methods: We performed the CCK-8 assay, fluorescence staining assay, flow cytometry, scratch healing assay, and
Transwell assay to detect the effects of different concentrations of ginsenoside Rb1 on the antitumor activity of
95D and NCI-H460 cells and Western Blot detected the mechanism of antitumor effect.
Results: Ginsenoside Rb1 treatment significantly increased the inhibition and apoptosis rates of 95D and NCIH460
cells and inhibited the cell cycle transition from S phase to G2/M. Rb1 induces apoptosis by altering the
levels of P53, Bax, Cyto-c, Caspase-8, Caspase-3, Cleaved Caspase-3, Bcl-2, MMP-2, and MMP-9 proteins and
activating the external apoptotic pathway.
Conclusion: Ginsenoside Rb1 inhibits proliferation and migration and induces apoptosis of 95D and NCI-H460
lung cancer cells by regulating the mitochondrial apoptotic pathway to achieve antitumor activity.
