Based on the inflammatory and fibrotic markers commonly observed in response to myocardial infarction and development of heart failure, we assessed the expression of mRNA for Tnfa, Il1b,Il6, Il18, Ccl2, Ccl3, Cxcl1, Cxcl2, Col1a1, Col3a1, Postn, and Tlr4 at 1 and 3 months (Figure 3A–X). The gene discussed is COL3A1; the disease is heart failure.
