However, DRF or MMF has only minor effects on lipid peroxidation (RA: 87 ± 6.8% after DRF treatment and 74 ± 3.4% after MMF treatment compared to untreated controls (Fig. 6b), OA: 85 ± 3.4% after DRF treatment and 80 ± 2.9% after MMF treatment compared to untreated controls (Fig. 6i) and survival (Figs. 6c, j) after induction of inflammation via TNFα in isolated primary fibroblasts cells from RA/OA patients. Here, TNF is linked to rheumatoid arthritis.
