SNHG3 and lip and oral cavity carcinoma: Similarly, lncRNAs AC007271.3 [70], MALAT1 [107], PLAC2 (placenta-specific protein 2) [120], SNHG3 (small nucleolar RNA host gene 3) [66], and TUG1 (taurine upregulated gene 1) [131] have been reported to induce the upregulation of β-catenin and subsequent activation of the WNT/b-catenin signaling downstream genes in oral cancer (Figure 2a), though the mechanistic details remain to be further investigated.
