V. opulus has been found to have outstanding antioxidant activity while showing a pro-oxidant effect at high doses. Due to this feature, V. opulus would be anticipated to have a healing impact on cancer treatment. In this study, it has been proposed to examine the cytotoxic, genotoxic, and apoptotic effects of V. opulus on human colorectal cancer cell. Method: Different concentrations of V. opulus methanolic extract (5-2000 μg/mL) were incubated for 24 h with colorectal cancer cell line (Lovo). The cell viability, intracellular reactive oxygen species (iROS), DNA damage, and apoptosis were measured after incubation. Results: The obtained results of this research demonstrate decreased cell viability and increased DNA damage, iROS, and apoptosis levels of V. opulus in Lovo cells in a concentration-dependent manner in the range of 14.88- 52.06%. There were strong positive relationships between apoptosis, genotoxicity, and cytotoxicity in V. opulus methanolic extract treated cancer cell line. Discussion: This in vitro research clearly demonstrated that V. opulus methanolic extract induces DNA damage, apoptosis, and cytotoxicity in a dose-dependent manner in cancer cells due to its pro-oxidant activity. Conclusion: Although in vitro results are favorable, in vivo and further studies are needed.
