SNHG18 and cancer: The lncRNA, small nucleolar RNA host gene 18 (abbreviated as snhg18 in mouse or SNHG18 in human), originally discovered in embryonic stem cells and provisionally named as Linc1290 by the authors,29 has been shown to be modulated during retinoic acid-induced embryonic stem cell differentiation.30 Thereafter, SNHG18 has been widely implicated in a variety of cancers.
