Through a combination of multi-omics analysis and in vitro experiments, this study identifies STIL as a critical molecular link between Li-Fraumeni syndrome and osteosarcoma. The research reveals that STIL functions as a negative regulator of p53 stability, promoting tumor growth and maintaining cancer stemness regardless of the patient's specific TP53 mutation status. Using single-cell sequencing, the authors demonstrate how STIL reshapes the tumor microenvironment to facilitate immune evasion and bone destruction via specific signaling pathways like PTN–NCL. Experimental validation shows…
