Figure 1. Acquired chemo- and radioresistance in liver cancer stem cells. Traditional chemo-/radiotherapy can induce genetic alteration in non-stem liver cancer cells (NSLCCs) via DNA damage and cytotoxic agent intake, in order to activate cellular apoptosis. However, upon treated with traditional chemo-/radiotherapeutic agents, liver cancer stem cells (LCSCs), can acquire chemo-/radioresistance including an increased level of drug intake and an enhanced DNA repairing mechanism, which eventually lead to a higher survival rate of LCSC subpopulation.
