Coordinated circRNA Silencing and Chemotherapy by pH-Responsive Nanoparticles Reprogram Cell Death in Drug-Resistant Osteosarcoma.
Chemoresistance remains a major clinical challenge in osteosarcoma, primarily driven by inefficient drug delivery and the evasion of cell death. Here, a multifunctional poly(β-amino ester) (pBAE)-based therapeutic delivery system was developed for simultaneous codelivery of small interfering RNA (siRNA) and doxorubicin...
