Glioblastoma (GBM) is both the most common and the most lethal primary brain tumor. It is thought that GBM stem cells (GSCs) are critically important in resistance to therapy. Therefore, there is a strong rationale to target these cells in order to develop new molecular therapies.To identify molecular targets in GSCs, we compared gene expression in GSCs to that in neural stem cells (NSCs) from the adult human brain, using microarrays. Bioinformatic filtering identified 20 genes (PBK/TOPK, CENPA, KIF15, DEPDC1, CDC6, DLG7/DLGAP5/HURP, KIF18A, EZH2, HMMR/RHAMM/CD168, NOL4, MPP6, MDM1, RAPGEF4, RHBDD1, FNDC3B, FILIP1L, MCC, ATXN7L4/ATXN7L1, P2RY5/LPAR6 and FAM118A) that were consistently expressed in GSC cultures and consistently not expressed in NSC cultures. The expression of these genes was confirmed in clinical samples (TCGA and REMBRANDT). The first nine genes were highly co-expressed in all GBM subtypes and were part of the same protein-protein interaction network. Furthermore, their combined up-regulation correlated negatively with patient survival in the mesenchymal GBM subtype. Using targeted proteomics and the COGNOSCENTE database we linked these genes to GBM signalling pathways.Nine genes: PBK, CENPA, KIF15, DEPDC1, CDC6, DLG7, KIF18A, EZH2 and HMMR should be further explored as targets for treatment of GBM.

Emergent evidences revealed that long noncoding RNAs (lncRNAs) participate in neoplastic progression. HMMR is an oncogene that is highly expressed in glioblastoma (GBM) and supports GBM growth. Whether lncRNAs regulate HMMR in GBM remains unknown. Herein, we identify that an HMMR antisense lncRNA, HMMR-AS1, is hyperexpressed in GBM cell lines and stabilizes HMMR mRNA. Knockdown of HMMR-AS1 reduces HMMR expression; inhibits cell migration, invasion, and mesenchymal phenotypes; and suppresses GBM cell growth both in vitro and in vivo. Moreover, knockdown of HMMR-AS1 radiosensitizes GBM by reducing DNA repair proteins ATM, RAD51, and BMI1. Our data demonstrate a mechanism of sense-antisense interference between HMMR and HMMR-AS1 in GBM and suggest that targeting HMMR-AS1 is a potential strategy for GBM treatment.
