Therapeutic synergies that overcome carboplatin resistance in triple-negative breast cancer

Isogenic PDX models of TNBC provide a powerful platform to define molecular mechanisms of acquired carboplatin resistance and uncover actionable therapeutic strategies. Our findings reveal multiple adaptive routes to platinum resistance, including restoration of homologous recombination and activation of alternative DNA repair programs. Synergistic interactions between SG and mTOR inhibition offer a promising avenue for overcoming resistance, supporting further clinical investigation of these combinations in TNBC.
