SNHG17 and glioma: The small nucleolar RNA host gene 17 (SNHG17), a lncRNA involved in cell progression and migration in several cancers, is upregulated by YY1 in GBM allowing the activation of the Wnt pathway by sponging miR-506-3p a direct negative regulator of catenin beta 1, extending its half-life and consequently facilitating glioma progression [221].
