One report showed that Wnt5a induces the expression of MCP-1 (monocyte chemotactic protein 1, also known as C-C Motif Chemokine Ligand 2, CCL2), a protein involved in macrophage recruitment (reviewed by Yoshimura, 2017), in two GC cell lines (BGC-803 and HGC-27) (Li et al., 2014). This evidence concerns the gene CCL2 and gastric cancer.
