Consistently, similar synergistic effects of the combination of specific FOXM1 inhibition strategies, such as siRNA, shRNA, inhibitor, and aptamers, against FOXM1, together with doxorubicin, have been previously reported to sensitize various human cancer cells to apoptosis induced by DNA-damaging agents, including doxorubicin [11,25,53,54]. Here, FOXM1 is linked to cancer.
