“…Many markers potentially specific for GSCs have been proposed such as A2B5 cell surface ganglioside epitope (A2B5) [26,27], aldehyde dehydrogenase (ALDH) [28], BMI1 polycomb ring finger oncogene (BMI1) [29,30], fucosyltransferase 4 (FUT4) (CD15) [31], Thy-1 cell surface antigen (Thy-1) (CD90) [32], prominin-1 (PROM1) (CD133) [5,6], chemokine (C-X-C motif) receptor 4 (CXCR4) [33], inhibitor of DNA binding 1 (ID1) [34], integrin α6 (ITGA6) [35], L1 cell adhesion molecule (L1CAM) [36], maternal embryonic leucine zipper kinase (MELK) [37], musashi-1 (msi1) [38], nestin (NES) [38][39][40], octamer-binding transcription factor 4 (OCT4) [41], OLIG2 [42] and SOX2 [38,[43][44][45]. Among these, much attention has been given to CD133, which is currently used to identify and isolate GSCs [40,43,[46][47][48][49][50].…”

Identification of OLIG2 as the most specific glioblastoma stem cell marker starting from comparative analysis of data from similar DNA chip microarray platforms

Despite advances in surgical and adjuvant treatments, overall survival of glioblastoma (GBM) patients remains poor. The cancer stem cell concept suggests that a rare stem cell population, called glioma stem cells (GSCs), has high ability to self-renewal leading to recurrence in GBM. The identification of specific markers of GSCs would provide a powerful tool to detect and to characterise them in order to develop targeted therapies. We carried out a comparative analysis based on the identification of inter-study concordances to identify the genes that exhibit at best differential levels of expression between GSC-enriched cell cultures and differentiated tumour cell cultures from independent studies using DNA chip microarray technologies. We finally studied the protein expression of the marker we considered the most specific by immunohistochemistry and semi-quantitative analysis on a retrospective series of 18 GBMs. Of the selected studies, 32 genes were retained. Among them, eight genes were identified to be overexpressed in GSC-enriched cultures compared to differentiated tumour cell cultures. Finally, among the eight genes, oligodendrocyte lineage transcription factor 2 (OLIG2) was characterised by the most different expression level in the "GSC model" compared to the "differentiated tumour cells model". Our approach suggests that OLIG2 is the most specific GSC marker; additional investigations with careful considerations about methodology and strategies of validation are, however, mandatory.

“…Since glioma CSCs were successfully isolated and cultured in vitro in 2004 (10), their characteristics have been studied extensively. Currently known glioma CSC markers include CD133, nestin, (sex determining region Y)-box 2 (SOX2), ATP-binding cassette sub-family G member 2 (ABCG2) and musashi-1 (11)(12)(13)(14)(15), with CD133 considered to be the most important of these markers. CD133…”

Abstract. Glioma is a type of tumor derived from glial cells, which is associated with a high level of incidence and mortality. At present, the generation of a fast and efficient method to evaluate the malignancy grade of glioma is required. Cancer stem cells (CSCs) are currently attracting attention in oncological studies; therefore, the present study aimed to investigate novel biomarkers of glioma CSCs, in order to provide new criteria for the grading of glioma. The mRNA expression levels of CD133, (sex determining region Y)-box 2, nestin, vascular endothelial growth factor (VEGF) and phosphoinositide-3-kinase (PI3K) were detected in 15 human samples of high-malignancy glioma and 12 human samples of low-malignancy glioma in vitro. The mRNA expression levels of VEGF and PI3K were higher in the high-malignancy group, as compared with in the low-malignancy group. In conclusion, the mRNA expression levels of VEGF and PI3K in glioma CSCs may be considered a novel criteria for the grading of glioma.

“…To further characterize IQGAP1 + cells, the intermediate filament protein nestin was used as a marker of neural stem/progenitor cells in GBM [21][22][23][24][25][26] in combination with Iba1. As can be observed in Figure 2K Figure S3).…”

Glioblastoma multiforme (GBM) is the most frequent and aggressive primary brain tumor. GBM is formed by a very heterogeneous astrocyte population, neurons, neovascularization and infiltrating myeloid cells (microglia and monocyte derived macrophages). The IQGAP1 scaffold protein interacts with components of the cytoskeleton, cell adhesion molecules, and several signaling molecules to regulate cell morphology and motility, cell cycle and other cellular functions. IQGAP1 overexpression and delocalization has been observed in several tumors, suggesting a role for this protein in cell proliferation, transformation and invasion. IQGAP1 has been identified as a marker of amplifying cancer cells in GBMs. To determine the involvement of IQGAP1 in the oncobiology of GBM, we performed immunohistochemical confocal microscopic analysis of the IQGAP1 protein in human GBM tissue samples using cell type-specific markers. IQGAP1 immunostaining and subcellular localization was heterogeneous; the protein was located in the plasma membrane and, at variable levels, in nucleus and/or cytosol. Moreover, IQGAP1 positive staining was found in podosome/invadopodia-like structures. IQGAP1 + staining was observed in neurons (Map2 + cells), in cancer stem cells (CSC; nestin + ) and in several macrophages (CD31 + or Iba1 + ). Our results indicate that the IQGAP1 protein is involved in normal cell physiology as well as oncologic processes.
