Figure 2. — Resveratrol induced apoptosis and regulated apoptosis-related protein levels in liver cancer cells. (A) Fluorescent microscopy images of TUNEL assay. DAPI staining (blue) was used to identify cell nuclei, TUNEL-positive cells are by green. Scale bar represents 100 µm. Bar graph showed the percentage of apoptotic cells. (B) Protein levels of PARP, cleaved PARP, caspase-3, caspase-7, Bcl-2 and Bax. Bar graphs showed their relative levels to β-actin, and the ratio of Bcl-2/Bax. *P<0.05 and **P<0.01 vs. control.
