ZNF93 gene expression was also shown to be increased in ET-743 resistant Ewing's sarcoma cell line (TC-ET) and in the cisplatin-resistant ovarian cancer cell line (A2780cp) but not in the paclitaxel resistant cell lines (SKOV-3TR) nor in the paclitaxel resistant breast cancer cell line (MCF-7TR), suggesting a fundamentally different mechanism for paclitaxel resistance from ET-743 or PM00104 resistance. Here, ZNF93 is linked to ovarian cancer.
