Seven major discriminators between control and tumor samples were found: expression levels of APOA1, PRDX3_a and CLIC1 were higher in tumors than in normal brain cortex, whereas significantly lower levels of NFM, CN37, NDUS1 and MDHC were found in tumors as compared with normal tissues (component PC1, Figure 3A, right). Here, CLIC1 is linked to neoplasm.
