Figure 1. Detection of circ_TNFRSF21 expression in HEC1-A. (A) Diagram of circ_TNFRSF21. (B) PCR results of TNFRSF21 exon 6 or circ_TNFRSF21 from cDNA or genomic DNA (gDNA) (C) Detection of circ_TNFRSF21 and TNFRSF21 exon 6 expression before and after RNase A treatment. (D) Pull down circ_TNFRSF21 with AGO2 or EIF4A, IgG was used as negative control. *P<0.05, **P<0.01, ***P<0.001, data are represented as mean +/- SEM.
