PTEN and carcinoma: We found that miR-32-5p was significantly over-expressed (239.85 ± 37.28-fold and 95.64 ± 31.92-fold in HCC and para-carcinoma tissues, respectively, p < 0.01, Fig. 2a), but PTEN was significantly lower-expressed (3.74 ± 1.36-fold and 74.29 ± 25.00-fold in HCC and para-carcinoma tissues, respectively, p < 0.01, Fig. 2b) in the 44 HCC specimens compared with the 28 para-carcinoma liver tissues.
