No studies however, have investigated the potential modulatory role of resveratrol (RV) on mitomycin C (MMC)-mediated effects on colorectal cancer. The aim of the present study was to investigate the impact of RV on MMC-mediated inhibition of colorectal cancer cell proliferation and to assess the potential mechanisms for such effects. Materials and Methods: Primary cell lines generated from resected colorectal tumor specimens were treated with RV, MMC or RV+MMC and cell proliferation and gene expression analyses were performed. Results: Suppression of cell proliferation by RV+MMC was significantly greater than individual treatments. RV+MMC synergistically modulated several genes but the up-regulation of p21WAF1/CIP1 was several-fold greater. Conclusion: The up-regulation of p21WAF1/CIP1, which inhibits the cell cycle at G0/G1 and G2/M phases, may represent the predominant mechanism for enhancement of MMC-mediated anti-cancer effects by resveratrol.}, issn = {0250-7005}, URL = {https://ar.iiarjournals.org/content/34/10/5439}, eprint = {https://ar.iiarjournals.org/content/34/10/5439.full.pdf}, journal = {Anticancer Research} }
