SYN2 and glioblastoma: A recent bioinformatics analysis on 3 glioblastoma-related microarray datasets from the Gene Expression Omnibus and The Cancer Genome Atlas identified SYN2 as a hub gene among the differentially expressed genes, with RNA and protein levels of SYN2 being downregulated in glioblastoma tissues and high expression of SYN2 associated with better overall survival among patients with glioblastoma [69].
