Proteins such as vimentin, α-2-macroglobulin, apolipoprotein B and A-I, antithrombin-III etc., which exhibited sequential changes in expression level in different malignancy grades, therefore significant alterations in expression level between the benign and atypical or anaplastic meningiomas, can be considered as potential disease monitoring markers (Table S6). This evidence concerns the gene APOB and meningioma.
