Abstract

Different phenolic compounds such as oleuropein and hydroxytyrosol have demonstrated antitumoral activity in cancer cell lines. Olive derivatives have demonstrated beneficial properties in cardiovascular diseases. The study was addressed to show the potential beneficial properties of olive leaves and olive oil mill waste extracts in hepatoma cell lines. Aflatoxin B1 (AFB1) was administered to hepatoma cell line (HepG2). Different parameters related to cell death, cell proliferation and DNA damage were determined. The expression of p53 and c-Src (activated and inhibitory phosphorylated state) was assessed by Western blot analysis in HepG2. The olive leaves and olive oil mill waste extracts contained oleuropein and hydroxytyrosol, respectively. AFB1 induced cell proliferation and death, associated to a rise on p53 and c-Src expression in HepG2 cells. Oleuropein and hydroxytyrosol reduced cell necrosis and DNA damage in HepG2 cells. However, the administration of olive leaves and olive oil mill waste extracts increased cell necrosis and DNA damage. These effects of natural extracts were associated with a reduction of activated c-Src expression and cell proliferation in AFB1-treated HepG2 cells. These results support that olive leaves extract and olive oil mill waste extracts, but not oleuropein and hydroxytyrosol, may exert antitumoral effect against a hepatoma cancer cell line.
