Lycopene in Association with α-Tocopherol Inhibits at Physiological Concentrations Proliferation of Prostate Carcinoma Cells

The effect of lycopene alone or in association with other antioxidants was studied on the growth of two different human prostate carcinoma cell lines (the androgen insensitive DU-145 and PC-3). It was found that lycopene alone was not a potent inhibitor of prostate carcinoma cell proliferation. Howe...

description The effect of lycopene alone or in association with other antioxidants was studied on the growth of two different human prostate carcinoma cell lines (the androgen insensitive DU-145 and PC-3). It was found that lycopene alone was not a potent inhibitor of prostate carcinoma cell proliferation. However, the simultaneous addition of lycopene together with α-tocopherol, at physiological concentrations (less than 1 μM and 50 μM, respectively), resulted in a strong inhibitory effect of prostate carcinoma cell proliferation, which reached values close to 90 %. The effect of lycopene with α-tocopherol was synergistic and was not shared by β-tocopherol, ascorbic acid and probucol.
