AEBP1 and familial dilated cardiomyopathy: We also evaluated changes in candidate protein-level expression in proteomic data generated from mass spectrometry-based analysis of LV heart tissue from patients with no heart failure (n = 7) and patients with dilated cardiomyopathy (n = 5) [12] and found that only AEBP1 was upregulated in DCM at the protein level (NF vs. DCM, p = 0.0062 **), concordant with our gene expression data (Figure 3E).
