In addition, serum miR-150-5p levels were also significantly downregulated in DM patients with anti-MDA5 antibodies (3.58 ± 2.02, 11 cases) compared with those without anti-MDA5 antibodies (6.19 ± 5.27, 38 cases; P = 0.017) (Figure 3(b)). The gene discussed is IFIH1; the disease is dermatomyositis.
