It is possible to develop new chemopreventive compounds so that cancer cells can be targeted in an exclusive manner. Bioactive natural compounds have demonstrated to be efficient chemotherapeutic agents, safe and cost-effective. Majority of anti-cancer medications are derived from natural sources, particularly of plant origins. Betanin (betanidin-5-O-β-glucoside) is the most common betacyanin with antioxidant, anti inflammatory and anticancer properties. The present study therefore investigated the effect of betanin onosteosarcoma MG-63 cells. The mechanistic pathway of inflammatory responses, cell proliferation and apoptosis were investigated. The MG-63 cells were treated with betanin for 24 h. Betanin actions on the appearance of cell arrangements, morphological changes, ROS induced Δψm , cell migration, cell adhesion and proliferative mechanistic marker expression of PI3K/AKT/mTOR/S6were analyzed. Betanin inhibited MG-63 cells at IC50 concentrations between 9.08 and 54.49 μM and induced apoptosis by triggering the ROS mechanism. Betanin inhibited proliferation and migration of MG-63 cells and induced DNA fragmentation. Betanin also modified the key mediator expression levels of PI3K/AKT/mTOR/S6 signaling pathways. Betanin can potentially be utilized in bone carcinoma therapeutics to inhibit, reverse or delay osteosarcoma.
