Specifically, the expression of IL-6 and MCP-1 increased approximately 3 times (Fig. 3B and C), while IL-8 and VCAM-1 were elevated by about 2.8 times (Fig. 3D and E), indicating that the cardiac inflammatory response was significantly activated in the DCM model. The gene discussed is CCL2; the disease is familial dilated cardiomyopathy.
