TP53 and diffuse large B-cell lymphoma: The DLBCL-associated network also reveals further regulatory associations between genes and miRNAs; for example, EGFR was found to regulate hsa-miR-21, which targets MYC; hsa-miR-21 was identified to target E2F1, which regulates hsa-miR-17; and TP53 was revealed to regulate hsa-miR-125b (hsa-miR-125b-1 and -2), which targets AKT1.
