We were interested in proteins that are known to be expressed in subsets of malignant glial tumours: while some proteins have been studied for this purpose in the past (EGFR) [24], others have been mostly studied in unrelated pathological processes (INSM1, SOX11, CD34) or have been studied only rarely in the context of diagnostic pathology (MEOX2). This evidence concerns the gene INSM1 and glioma.
