Isocudraxanthone K Induces Growth Inhibition and Apoptosis in Oral Cancer Cells via Hypoxia Inducible Factor-1α
Figure 2
Confirmation of isocudraxanthone K- (IK-) induced apoptosis by cell cycle analysis (a), annexin V-PI flow cytometry (b), and DAPI staining (c, ×400) in HN4 and HN12 cells. Cells were incubated with 20 μM IK for 2 days. The results are representative of three independent experiments.
