The selection of human cancer cell lines in cis-diamminedichloroplatinum(II) (CDDP, best known as cisplatin) is accompanied by stereotyped alterations that contribute to the acquisition of a CDDP-resistant state. Thus, CDDP resistance often leads to the upregulation of the DNA repair enzyme poly (ADP-ribose) polymerase-1 (PARP1) with the consequent intracellular accumulation of poly (ADP-ribose) (PAR)-modified proteins. Here we report another frequent alteration accompanying CDDP resistance, namely upregulation of the antiapoptotic BCL-2 family protein MCL-1. Six out of 8 CDDP resistant cancer cell lines manifested an increase in MCL-1 protein expression level, while only a minority of cell lines overexpressed BCL-2 or BCL-XL. BCL-XL was decreased in six out of 8 cancer cell lines. Importantly, MCL-1 overexpressing, CDDP resistant cells appear to be 'addicted' to MCL-1 because they died upon depletion of MCL-1 by RNA interference or pharmacological inhibition of MCL-1 expression by the BH3 mimetic obatoclax. Knockdown of PARP1 did not succeed in reducing MCL-1 expression, while depletion or inhibition of MCL-1 failed to affect the activity of PARP1. Hence, the two resistance mechanisms are not linked to each other by a direct cause-effect relationship. Importantly, CDDP-resistant, MCL-1 overexpressing human non-small cell lung cancers responded to monotherapy with obatoclax in vivo, in xenotransplanted mice, underscoring the probable therapeutic relevance of these findings.
