MAPK-driven MYC/p21 axis controls senescence bypass and BCL-XL dependence in vincristine-resistant rhabdomyosarcoma
Summary Therapy resistance remains the primary cause of treatment failure in rhabdomyosarcoma (RMS), the most common pediatric soft tissue sarcoma, yet underlying mechanisms are poorly understood. Using vincristine-resistant fusion-negative RMS models, RNA sequencing, genetic perturbations, and a syngeneic zebrafish tu...
