This work identifies HMGB3 as a promising immunotherapeutic target in the MLIA subtype of TNBC and highlights Pimicotinib, CID17584963, and CID1763476 as potential HMGB3 inhibitors for drug repurposing strategies.
These findings conclusively demonstrated that pharmacological inhibition of CSF-1R activity by ABSK021 resulted in significant anti-tumor effects in preclinical osteosarcoma models with CSF-1R overexpression. The high prevalence of CSF-1R expression observed in osteosarcoma patient samples highlights the potential clinical use of ABSK021, either as a monotherapy or in combination with chemotherapy, as a promising therapeutic strategy for osteosarcoma patients with CSF-1R as a potential predictive biomarker.
