CXCR1 and hepatocellular carcinoma: A similar pattern was observed; the expression of CXCR1 was suppressed in HCC samples compared to their normal part (−1.33-fold, p = 1.00), and the expression of CXCR2 was induced in the HCC samples compared to their normal tissue (1.137-fold, p = 0.004) (Figure 1B).
