UBR5-KDM5A axis rewires redox metabolism to confer cisplatin resistance in triple-negative breast cancer via the cAMP-PKA-SIRT3 cascade.
Triple-negative breast cancer (TNBC) lacks actionable therapeutic targets and remains highly dependent on cytotoxic chemotherapy, yet the rapid emergence of cisplatin resistance severely limits clinical benefits. The molecular mechanisms underlying this resistance and effective combination strategies remain incompletel...
