Novel Aptamer-Drug Conjugate for Targeted Therapy in Triple-Negative Breast Cancer

clathrin-mediated endocytosis. Furthermore, we constructed an aptamer-drug conjugate (ApDC) to selectively deliver a cytotoxic agent (SN38) to TNBC cells and demonstrated significant efficacy and safety in a TNBC xenograft model. These findings suggest that AptT1-based ApDC holds great potential as an innovative targeted strategy for TNBC.
