“…A limited qPCR study of four miRs also found that LVAD treatment normalized abnormal expression, but suggested that this effect was more pronounced in ischaemic cardiomyopathy. 79 The remarkable sensitivity of the miR signature to biomechanical support, which is known to favourably effect both cardiac performance and remodelling, parallels regulated expression of Dicer, the critical enzyme for processing to mature miRs (see above). Dicer levels are decreased in human heart failure, but normalized by LVAD treatment.…”

“…[7][8][9][10] Furthermore, unique miRNA expression profiles had been detected in human cardiomyopathy and pressure overloaded cardiac hypertrophy, and many miRNAs were dysregulated in the heart, indicating the involvement of miRNAs in cardiac diseases. 7,[11][12][13][14][15][16][17] It is well established that Ang II-mediated cardiac remodeling is a multigene disorder that involves a global change in the gene expression profile. miRNA analysis provides a novel mechanism for this alteration.…”

“…Morphological changes during LVAD support were paralleled by changes in collagen turnover and expression of genes encoding for structural collagens (Type I and III;Bruggink et al, 2006b;2007). So, the minor changes observed in expression of ECM genes in the present study may imply that most ECM changes are induced post-transcriptionally, either by micro-RNA regulation (Schipper et al, 2008) or in the matrix itself (e.g. by MMP).…”
