PTCH1 was negatively correlated with miR-212 in PDAC tissues. (A) Immunostaining of PTCH1 in PDAC tissues. a. Immunostaining of PTCH1was very weekly positive in PDAC tissues. b. PTCH1was positive in adjacent normal tissues. (B) PTCH1 mRNA level was examined by qRT-PCR and it was remarkably decreased in PDAC tissues. (C) PTCH1 mRNA level was inversely correlated with miR-212 level in PDAC tissues. (Spearman’s correlation analysis,r = -0.5157, P = 0.001). *P < 0.05.
