These assays showed that the nine selected lncRNAs (LINC00900, MIR210HG, MIR22HG, PVT1, SNHG18, HAR1A, LINC00641, SLC25A21-AS1, and SNAI3-AS1) were expressed to different extents in NBT, LGG, and GBM tissues at the mRNA level (Figure 8a–i), in accordance with the bioinformatics results. The gene discussed is SNAI3; the disease is glioblastoma.
