20 (S)-Ginsenoside-Rh2 and 20 (R)-Ginsenoside-Rh2 Activate IkappaB Phosphorylation Expression in Human Lung Adenocarcinoma A549 Cells

摘要

To study the underlying mechanism of 20 (S)-Ginsenoside-Rh2 and 20 (R)-Ginsenoside-Rh2 inducing apoptosis of human lung adenocarcinoma A549 cells. In this study, cell death rate and cell survival rate were obtained using typan blue staining cell viability assay, and transmission electron microscopy was used to detect cell apoptosis. Meanwhile, IkappaB phosphorylation expression was analysed by western blotting. Results showed that after A549 cells were treated with 30 ug/mL 20(S)-Rh2 and 20(R)-Rh2 for 48h, cell death rate increased significantly compared with the control group (P<0.05), and nuclear condensation, fragmentation, karyopycnosis and apoptotic bodies were found under transmission electron microscope.
