Abstract:
Osteosarcoma is a highly aggressive primary bone tumor that predominantly affects children and adolescents.Conventional treatment modalities are often hindered by issues such as high recurrence rates and the development of drug resistance.Proteolysis-Targeting Chimeras(PROTACs)represent an innovative therapeutic strategy for osteosarcoma,which are designed to selectively degrade pathogenic proteins.This article offers a comprehensive analysis of the mechanisms underlying PROTACs,their tar-geted applications in osteosarcoma—including bromodomain and ultra-terminal domain targeting—and the associated challenges,such as delivery efficiency and off-target toxicity.Additionally,it suggests optimi-zation strategies for bone-targeted delivery(such as using DNA nanoflowers as carriers)and combination therapies(like targeted therapy and chemotherapy),informed by recent research findings,thereby provi-ding a theoretical framework for clinical translation.
