Glioblastoma is an aggressive brain tumor. GlioBank is a live collection of tumor samples and patient data in Slovenia designed to help researchers study this disease better. In this study, the authors wanted to see how genetic changes in glioblastoma might be linked to the growth and aggressiveness of tumors. To do this, they analyzed the expression of genes from tumor samples of 91 patients with glioblastoma. Their results showed that certain genes, like DAB2, S100A4, and STAT3, were linked to worse survival of patients.
