Accordingly, qRT-PCR analysis demonstrated that the expression of proinflammatory cytokines, including interleukin-6 (Il6), Il1β, tumor necrosis factor–α (Tnfα), and monocyte chemoattractant protein-1 (Mcp1), were notably decreased in HMRKO mouse hearts after MI (Fig. 2E). The gene discussed is IL1B; the disease is myocardial infarction.
