IDH1 and glioblastoma: Of note, SLUG (median test: p=0.0098) and TWIST (median test: p=0.0315) expression were significantly higher in IDH-1-wildtype as compared to IDH-1-mutant (R132H) glioblastomas, most probably related to the a priori more prominent neoangiogenesis in primary glioblastoma (data not shown).
