abstract：:Cucurbitacin B is a natural anti-cancer compound found in Cucurbitaceae. Although the anti-cancer activity of cucurbitacin B in human leukemia cells has been reported, the underlining mechanism is still unclear. To clarify its anti-cancer activity and the mechanism of action, five different leukemia cell lines (CCRF-C...
