SNHG1 and neoplasm: Several other lncRNAs have also been shown to function as oncogenes through sponging miRNAs and positively regulating their target tumor-promoting genes, including CCAT1 [69], NEAT1 [70], plasmacytoma variant translocation 1 (PVT1) [71], small nucleolar RNA host gene 1 (SNHG1) [72], UCA1 [73], and XIST [74].
