Capsanthin induces death in human prostate cancer cell lines by inducing DNA damage


There is a relationship between a person’s diet and the development and prevention of some cancers. Carotenoids are found as various natural pigments in many fruits and vegetables. Studies on carotenoids and their potential roles in carcinogenesis are increasing in importance day by day. In this study, we aimed to determine the cytotoxic and genotoxic effects of capsanthin, a carotenoid compound, in human prostate cancer cell lines.

After different concentrations of capsanthin were applied to human prostate cancer cell lines (LNCaP and PC-3), the effects of the compound on cell viability were determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) test. The single-cell gel electrophoresis (Comet) assay was then used to reveal the genotoxic effects of probable cytotoxic dosages on cell DNA. After the treatments, apoptotic cell death levels were determined by Tunel staining. At high concentrations, capsanthin dramatically reduced PC-3 and LNCaP cell viability (p<0.05). In addition, capsanthin caused DNA damage and apoptotic cell death in the prostate cancer cells. The results show that capsanthin reduces cell viability by causing genotoxicity in prostate cancer cells.
