First, we validated the concordant differential expression of monoamine oxidase type B (MAOB) (transcript LFC 0.7, protein LFC 3.19), fatty acid-binding protein 7 (FABP7) (transcript LFC 1.63, protein LFC 6.68) and retinol-binding protein 1 (RBP1) (transcript LFC 1.12, protein LFC 3.44) at the protein level by Western blot (WB) using an independent cohort of five meningioma tissues of both grade I and grade III. This evidence concerns the gene FABP7 and meningioma.
