The relative expression of PTEN, β-catenin and c-Jun in EHCC and their paired para-carcinoma tissues.

<p>(A, B, C) The mRNA expression level of PTEN, β-catenin and c-Jun in the primary EHCC and their paired para-carcinoma tissues determined by qRT-PCR. β-actin was used as the internal control (^★P<0.05, ^★★★P<0.001). (D) The inverse correlation of PTEN and miR-221 expression levels was examined by Spearman correlation analysis (R = -0.429, P = 0.032).
