Figure 4. Knockdown of ERK3 and TDP2 promotes PARP-1 cleavage induced by etoposide.

Figure 4

H460 cell pools stably expressing either non-targeting shGIPZ or shERK3 were transiently transfected with either non-targeting control siRNA (siCtrl) or siRNA specifically targeting TDP2 (siTDP2). 24 hrs post-siRNA transfection, cells were treated with either DMSO or etoposide for 2 days. PARP-1 cleavage was analyzed by Western blotting.
