MCL‐1, a member of the anti‐apoptotic B‐cell lymphoma‐2 (Bcl‐2) protein family, is notably upregulated in the synovial macrophages of RA patients.[195] MCL‐1 shields overactivated macrophages from apoptosis by suppressing apoptotic signaling pathways.[196] Based on the above mechanism, Li et al. This evidence concerns the gene MCL1 and rheumatoid arthritis.
