Additional markers included histone H4, α-2-antiplasmin isoform X2, HSP90-α, peroxiredoxin-1, deleted in malignant brain tumors-1 protein-like isoform X2, ceruloplasmin, clusterin, and mannose-binding lectin precursor, etc.; however, these were only statistically significant in one comparison (e.g., leghorn TEX vs. VEX), but not the other (Supplementary files S4, S5). The gene discussed is PRDX1; the disease is brain neoplasm.
