FGFR1 and hepatocellular carcinoma: Meanwhile, a significant positive correlation was found between FGFR1 protein expression levels and UCA1 expression levels in HCC tissues (r = 0.7114, P < 0.0001); whereas, a significant negative correlation was found between FGFR1 protein expression levels and miR-216b expression levels in HCC tissues (r = −0.5040, P < 0.0001; Figure 6C).
