Besides the molecules mentioned above (ERCC2, ERCC5, CYTB, COX1, COX3, ND1, ND2, and ATP6), the expression levels of X-ray repair cross-complementing 6, COX2, and ATP8 were also decreased in patients with SLE (Figures 3 and 4). The gene discussed is MT-ATP6; the disease is systemic lupus erythematosus.
