Proteins like Transferrin (TF), Apolipoprotein B (APOB), Cytochrome c oxidase subunit III (CO3), and Albumin (ALBU) were found to be significantly altered with a p-value ≤ 0.05 in high grade Meningioma, shown as a heatmap in Fig. S2D. Expression levels of some significant proteins like transferrin, gelsolin and apolipoprotein B have been represented with refined peaks and group-wise box plots. This evidence concerns the gene APOB and meningioma.
