HO-1 up-regulation induced resistance to IM in K562 cells.
A, as a result of silencing HO-1 expression in K562R cells, the apoptosis induced by IM was increased significantly. B, up-regulation of HO-1 in K562 cells mediated by lentivirus leaded to IM resistance. Con, control. ** indicates p < 0.01, and ## indicates p < 0.01.
