PXN-AS1 and glioblastoma: For example, LINC00470 mediated GBM cell autophagy by activating AKT.13 LncRNA HOTAIRM1 was overexpressed in GBM and promotes cell invasion and tumour growth via up‐regulating HOXA1.14 LncRNA PXN antisense RNA 1 (PXN‐AS1) was reported to be down‐regulated in pancreatic cancer cells and suppressed cancer progression.15 However, the expression of PXN‐AS1 was found to be up‐regulated in GBM tissues through GEPIA database.
