(A), Pancreatic CSCs were transiently transfected with either negative control (scrambled) or anti-miR34a oligonucleotide and treated with Aza-5dC (4 µM) for 48 h. Western blot analysis was performed to measure the expression of cyclin D1, CDK2, p27 and VEGF. β-actin was used as a loading control. (B), Pancreatic CSCs were transiently transfected with either negative control (scrambled) or anti-miR34a oligonucleotide and treated with SAHA (3 µM) for 48 h. Western blot analysis was performed to measure the expression of cyclin D1, CDK2, p27 and VEGF. β-actin was used as a loading control. (C), Regulation of VEGF-B 3′UTR-Luciferase activity by Aza-5dC. Pancreatic CSCs were transfected with either negative control (scrambled) or anti-miR34a oligonucleotides along with VEGF-B 3′UTR-LUC construct, and treated with Aza-5dC (0–3 µM) for 24 h. Luciferase activity was measured as per manufacturer's instructions (Promega). Data represent mean ± SD. *, @ or # = significantly different from control, P<0.05. (D), Regulation of VEGF-B 3′UTR-Luciferase activity. Pancreatic CSCs were transfected with either negative control (scrambled) or anti-miR34a oligonucleotides along with VEGF-B 3′UTR-LUC construct, and treated with SAHA (0–3 µM) for 24 h. Luciferase activity was measured as per manufacturer's instructions (Promega). Data represent mean ± SD. *, @, # = significantly different from control, P<0.05.
