In DLBCL, three snoRNA host genes have been proposed to function as miRNA sponges: small nucleolar RNA host gene 12 (SNHG12) sequesters miR-195 to control the cell growth, migration, and invasion of DLBCL cells in vitro [80]; small nucleolar RNA host gene 14 (SNHG14) sponges miR-5590-3p to upregulate Zinc finger E-box binding homeobox 1 (ZEB1); and small nucleolar RNA host gene 16 (SNHG16) sequesters miR-497-5p, to derepress the Pim-1 proto-oncogene, serine/threonine kinase (PIM1). This evidence concerns the gene ZEB1 and diffuse large B-cell lymphoma.
