As shown in Figure 3(a), the serum levels of IL-6, IL-12, and CCL2 increased in the DCM group compared to those in the control group (IL-6:127.87 ± 2.49 pg/ml versus 111.41 ± 5.58 pg/ml, p < 0.05; IL-12 : 89.37 ± 2.3 pg/ml versus 80.45 ± 3.4 pg/ml; p < 0.05; CCL2: 90.45 ± 2.88 ng/ml versus 81.58 ± 3.59 ng/ml; p < 0.01). The gene discussed is IL6; the disease is familial dilated cardiomyopathy.
