IKBKB and diffuse large B-cell lymphoma: In an earlier study, we reported that miR-28 downregulates B-cell expression of a gene network downstream of the BCR signaling pathway and that miR-28 expression inversely correlates with that of genes downstream of BCR signaling, including NF-κB2, IKKB, and Bcl-2 in ABC-DLBCL [19].
