Why cisplatin kills breast cancer cells when other drugs fail

Triple-negative breast cancer cells are sensitive to cisplatin due to increased expression of delta-Np63 and TAp73 proteins. Cisplatin releases TAp73 from delta-Np63, leading to cell death. This study suggests using cisplatin as an early treatment option for individuals with triple-negative breast cancer.

Risk and outcome similar for bypass surgery, drug-eluting stents
