SNHG7 and glioblastoma: In other studies, Ren et al. demonstrated that siRNA knock-down of the lncRNA SNHG7 (small nucleolar RNA host gene 7, a lncRNA upregulated in several cancers, including GBM tissues and cell lines) in A172 and U-87 MG cells reduced cell proliferation, migration and invasion, and activated apoptosis.
