Title: Molecular remodeling of ion channels, exchangers and pumps in atrial and ventricular myocytes in ischemic cardiomyopathy: left ventricle DCM      
dateReleased:
06-17-2010
description:
We wanted to see whether the set of affected genes in ischemic cardiomyopathy (ICM) is the same or different as compared to dilated cardiomyopathy (DCM). To find this out, we placed the single DCM sample on the same microarray slide with the ICM samples. Analysis of microarray data with ICM samples only showed 63 affected genes, while that carried out with 2 ICM samples PLUS one DCM sample reduced this number to just four genes. From this result we conclude that ICM and DCM affect different sets of genes in ventricular myocytes. Keywords: Expression profiling by array From the associated publication: To find out whether the splice microarray results reported in Table 3 are disease-type specific, we supplemented the same splice microarray of ICM ventricular myocytes with one additional sample prepared from left ventricle of a 41-years old dilated cardiomyopathy male donor. The top-list ANOVA gene score annotation for combined altered CE&P genes in ventricular myocytes (Table 3) was reduced from 63 to just 4 genes (FXYD1 (Gfold = +2.4), HCN2 (-1.5), GLRA1 (-1.8) and GJC1 (-2.3)).
