CXCL12 and neoplasm: Hui and colleagues reported that miR-101, by targeting C-X-C chemokine receptor 7 (CXCR7), which is overexpressed in OSCC, prevents its binding to C-X-C chemokine ligand 12 (CXCL12) that is encoded by the CXCL12 gene, thus reducing cell adhesion, viability and tumor growth (75).
