APC and diffuse large B-cell lymphoma: We assessed the expression of circEAF2, miR-BART19-3p and APC in tumor samples of DLBCL by qRT-PCR (Fig. 5B) and found significant negative correlation between circEAF2 and miR-BART19-3p (P = 0.0493), positive correlation between circEAF2 and APC (P < 0.0001), and negative correlation between miR-BART19-3p and APC (P = 0.0443).
