TUG1 and diffuse large B-cell lymphoma: Lastly, several studies have shown aberrant expression patterns of the lncRNAs small nucleolar RNA host gene 12 (SNHG12), SNHG14, SNHG16, TUG1, MALAT1 and SMAD5 antisense RNA 1 (SMAD5-AS1) in DLBCL samples and cell lines, indicating their use as potential biomarkers, although further investigation is warranted [148–153].
