a Relative circ-ASH2L expressions of Hs 766 T and Hs 766 T-L2 were measured by qRT-PCR. b Relative circ-ASH2L expressions of HPDE (the normal pancreatic cell line) and the indicated PDAC cells were measured by qRT-PCR. c Relative circ-ASH2L expressions of HPDE (the normal pancreatic cell line) and the indicated PDAC cells were measured by qRT-PCR. d qRT-PCR analysis of circ-ASH2L or β-actin after treatment of RNase R in Capan-1 and Aspc-1 cells. e qRT-PCR analysis of circ-ASH2L and β-actin after treatment of Actinomycin D at the indicated time points in Capan-1 cells. f qRT-PCR analysis of circ-ASH2L and β-actin after treatment of Actinomycin D at the indicated time points in Aspc-1 cells. g Relative expressions of circ-ASH2L in indicate treated Capan-1 and Aspc-1 cells was measured by qRT-PCR. h The PCR products of Capan-1 cells were confirmed by Sanger sequencing to show the back-splice junction. i Schematic outlining the details of circ-ASH2L and its primer-designing details
