Figure 4: Effects of olive leaves (A) and olive oil mill waste (B) extracts on cell proliferation in Aflatoxin B1 (AFB1)-treated HepG2 cells. Cell proliferation was determined by BrdU incorporation in HepG2 cells. Samples were collected at 24 hours. The groups with “a” were significantly different vs. the corresponding control group. The groups with “b” were significantly different vs. the corresponding group without AFB1.
