摘要: New anticancer agents with lower toxicity have been always urged because of drug resistance associated overused chemotherapy agents. In this study, steviol, a colonic metabolite natural sweetener and also component in leaves stevia rebaudiana bertoni, was found to possess intensive activity on the human gastrointestinal cancer cells. Steviol inhibited six cells intensively as 5-fluorouracil did at 100 μg/mL. The inhibition mechanism follows mitochondrial apoptotic pathway that evidenced by increase Bax/Bcl-2 ratio, activation p21 p53; caspase 3-independent involved. These results are consistent miRNA expression analysis. most regulated miRNAs steviol treated were miR-203a-3p (log2 =1.32) miR-6088 =-2.54) HCT-116, miR-1268b =19.85) miR-23c =-2.05) MKN-45. view metabolic characteristics its cytotoxicity cells, could be agent potentially for treatment.
