PCBP1 and hepatocellular carcinoma: The result suggested that in HCC tissues, PCBP1 showed significant negative correlation with the expression of v6 (n = 33, r = -0.74689 p < 0.0001) (Figure 5A), that is, in HCC patients which PCBP1 was down-regulated compared to the non-cancerous liver tissue, the CD44 v6 expression level showed a significant up-regulation.
