Abstract

Purpose: Prostate cancer is as far the most prevalent male cancer. Rutin (a glycoside from quercetin flavonoid) displays antioxidant activity leading to cell apoptosis. Combined effects of rutin with the widely used anti-cancer drug, 5-fluorouracil (5-FU), on prostate cancer cell line (PC3) was investigated herein.

Methods: Different concentrations of combined 5-FU and rutin were applied to PC3 cells compared to separate treatment for 48 hours. Cell viability, as well p53 gene expression respectively were assessed by MTT assay and real-time quantitative polymerase chain reaction (qPCR). Changes of Bcl-2 signal protein and apoptosis were determined using western blot and flow cytometry procedures, respectively. Clonogenic assay was used to colony counts assessment.

Results: 50% inhibitory concentration (IC50) of separate cell treatment with either rutin and 5-FU respectively were 900 μM and 3Mm, while combination index (CI) of combined 5-FU /rutin application reached a level of synergistic effects (0.33). Combination of 5-FU/rutin enhanced apoptosis and p53 gene expression in PC3 cells. PC3 cell colony counts and Bcl-2 signaling protein were decreased by 5-FU/rutin combination.

Conclusion: Synergistic effects of 5-FU/rutin combination on PC3 cells line enhanced apoptosis, p53 gene expression, and down-regulation of Bcl-2 protein, compared to control separate application. 5-FU/rutin combination does seem an interesting therapeutic pathway to be further investigated.
