Fig. 4From: Long non-coding RNA CASC2 upregulates PTEN to suppress pancreatic carcinoma cell metastasis by downregulating miR-21Knockdown of PTEN abolished the effect of CASC2 on the metastasis of PANC-1 cells. PANC-1 cells were transfected with the CASC2-expressing vector (pEX-CASC2), PTEN shRNA or the corresponding negative controls for 48 h. Then, a cell migration was detected. b Cell invasion was detected. ***P < 0.001. Scale bar: 100 μmBack to article page
