PURPOSE: In this work, we aimed to comprehensively document the expression of Strawberry Notch homolog (SBNO) 1 and 2 in glioblastoma (GBM) tissue and patient-derived GBM stem-like cell (GSC) cultures.
METHODS: We investigated SBNO1 and SBNO2 expression at the RNA and protein levels in glioma patient tissue and GSCs, respectively by performing immunostainings and qPCR analyses. We also used publicly-available datasets for assessing SBNO1 and SBNO2 gene expression and related copy number alterations. We used lentiviral transduction of SBNO2 to analyze the effect of its expression in patient-derived GSCs.
RESULTS: We observed that SBNO2 expression is increased in GBM tissue samples compared to non tumoral brain, or lower-grade gliomas, whereas SBNO1 expression remains unchanged. We hypothesized that such SBNO2 high expression might be linked to copy-number alterations at the level of the 19p13 chromosome section. We located SBNO1 and SBNO2 in different subcellular compartments. Finally, we observed that SBNO2 overexpression induces different phenotypes in different patient-derived GSCs.
CONCLUSION: These results provide the first characterization of SBNO1 and SBNO2 expression in glioma tissue, and indicate SBNO2 as highly expressed in GBM.
