Hwang et al. demonstrated that C-X-C motif chemokine ligand 11 (CXCL11) secreted by senescent human umbilical vein endothelial cells (HUVEC) binds to CXCR3 in MDA-MB-231 cells and promotes the migration and invasion of cancer cells in vitro through the ERK pathway. This evidence concerns the gene CXCL11 and cancer.
