CXCL5 and hepatocellular carcinoma: The expression of CXCL5 in HCC tissues and normal tissues was detected in the GEPIA database; although the expression of CXCL5 has no significance in HCC tissues than in normal tissues (Figure 1(a)), we observed that the overexpression of CXCL5 in HCC patients predicted poor prognosis (P < 0.05) (Figure 1(b)).
