CXCR2 and osteosarcoma: In this comprehensive study, we explored the molecular landscape C-X-C chemokine receptor (CXCR) family genes (CXCR1, CXCR2, CXCR3, CXCR4, CXCR5, and CXCR7) in osteosarcoma (OS) by scrutinizing the expression profiles and functional implications using Bioinformatics analyses and molecular experiments.
