Fig. 4From: Drug resistance mechanisms and treatment strategies mediated by Ubiquitin-Specific Proteases (USPs) in cancers: new directions and therapeutic optionsUSPs regulate molecular targeted drug resistance. A USPs deubiquitinate key nuclear proteins, enhancing DNA damage repair and leading to resistance to PARP inhibitors. Inhibitors targeting USP7 improve the therapeutic efficacy of PARP inhibitors in treating cancer. B USPs are involved in imatinib (IM) resistance in chronic myeloid leukemia (CML) and gastrointestinal stromal tumorsBack to article page
