MALT1 induced immune response is governed by miR-2909 RNomics.

The paracaspase mucosa-associated lymphoid tissue 1 (MALT1) has been widely recognized to play crucial role in lymphocyte activation, development and the generation of lymphomas through the modulation of innate and adaptive immune responses. Our results reported here provide evidence for the first time to support the view that MALT1 exerts its effect upon immune response involving genes coding for retinoic acid-inducible gene 1 (RIG1); interferon-β (IFN-β); apo-lipoprotein B mRNA-editing, enzyme-catalytic, polypeptide-like 3G (APOBEC3G); IFN-γ; chemokine (C-C motif) ligand 5 (CCL5) and interleukin-17 (IL-17) through the initiation of cellular miR-2909 RNomics. This ensures sustained expression of specificity protein 1 (SP1)-dependent regulation of genes that in-turn governs MALT1 induced immune response. Based upon these results, a mechanistic-pathway is proposed that links the epigenomic-interplay between MALT1 and miR-2909.
