MSC-AS1/miR-29b-3p axis modulates CDK14 and cell cycle-related proteins expression in PDAC cell. (a)Panc-1 and BxPC-3 cells were co-transfected with miR-29b-3p inhibitor and MSC-AS1 shRNA and then examined for protein levels of CDK14, c-Myc, cyclin D1, cyclin Y and cyclin D3 using westernblot, the protein density analysis were shown in (b-f). The data are presented as mean ±SD of three independent experiments. *P < 0.05, **P < 0.01, compared to control group; ##P < 0.01, compared to MSC-AS1 shRNA group.
