FOXO1 and glioblastoma: When specific to glioblastoma, both high cytoplasmic FOXO1 and pFOXO1 expression were associated with shorter OS and PFS (OS: 10 months versus 15 months for both, PFS: 8 months versus 15 months for FOXO1 and 7 months versus 12 months for pFOXO1 respectively) (Fig.3C, 3F, S1C, S1F).
