CXCR4/MIF axis amplifies tumor growth and epithelial-mesenchymal interaction in non-small cell lung cancer

Overexpression of C-X-C chemokine receptor type 4 (CXCR4) has been shown in several cancers, including non-small cell lung cancer (NSCLC) and is linked to early metastasis and worse prognosis. The crosstalk between cancer cells and tumor stroma promotes the growth and metastasis and CXCR4 signaling is a key element of this crosstalk. To test the effects of CXCR4 overexpression (CXCR4-OE), we transduced the human NSCLC cell line A549 by using a...
