Deubiquitinating enzyme USP42 promotes breast cancer progression by inhibiting JNK/p38-mediated apoptosis
USP42, a deubiquitinating enzyme, plays a critical role in breast cancer progression by inhibiting apoptosis through the JNK/p38 signaling pathway. The study demonstrates that higher levels of USP42 correlate with advanced cancer stages and poor prognosis. Knockdown of USP42 in breast cancer cell lines led to reduced cell proliferation and increased apoptosis, indicating its potential as a therapeutic target. These findings underscore the importance of USP42 in breast cancer biology and highlight the need for further investigation into its mechanisms.
