CAT and myeloid sarcoma: Biomarker research goals include determining the usefulness of tNOx, S-nitrosothiol, SOD, myeloperoxidase (MPO), glutathione-disulfide reductase (GSR), catalase, protein carbonyls, advanced oxidation protein products (AOPPs), F2-isoP, MDA, and oxycholesterols as potential prognostic biomarkers for MS, determining the usefulness of SOD, nuclear factor erythroid 2-related factor 2 (Nrf2), protein carbonyls, 3-NO-Tyr, AOPPs, and MDA as possible predictive biomarkers for response to treatment, and investigating SOD as a therapeutic drug target in MS [63,80].
