CXCL13 is a potent chelator that boosts accretion of CXCR5-expressing cells, while silencing CXCL13 and CXCR5 in CRC inhibits TAM-mediated metastasis, suggesting that exosomal miR-934 promotes CRLM progression by targeting the CXCL13/CXCR5 axis. The gene discussed is CXCL13; the disease is colorectal carcinoma.
