BackgroundExtracellular matrix
turnover is regulated by matrix metalloproteinases (MMPs) and a family
of tissue inhibitors of metalloproteinases (TIMPs).
Together, these proteins may contribute to myocardial remodeling in
congestive heart failure. We hypothesized that the expression of MMPs
and TIMPs might be differentially regulated in the failing human
heart.
Methods and ResultsNorthern blot analyses were performed
with probes to TIMP-1 to -4 and GAPDH with poly A+ mRNA
from ventricular tissues of patients with ischemic
cardiomyopathy (ICM, n=16) or idiopathic dilated
cardiomyopathy (DCM, n=15) and nonfailing control
hearts (n=15). TIMP-1 to -4 and MMP-9 proteins were quantified by ELISA
and/or Western blot, and the total gelatinolytic
activity was studied by gelatin zymography. The results showed that
cardiac expression of TIMP-1 and -3 transcripts and proteins was
significantly reduced in ICM and DCM. No significant difference was
observed in TIMP-2 and -4 transcripts. However, TIMP-4 protein was
significantly reduced in ICM myocardium. MMP-9 protein
content and total gelatinolytic activity were
upregulated in the same samples.
ConclusionsThese studies demonstrated a selective downregulation
of TIMPs along with upregulation of MMP-9 and
gelatinolytic activity in the failing hearts,
alterations that favor matrix degradation and turnover. These findings
might be of pathophysiological significance and
might suggest new therapeutic targets for limiting the
ventricular remodeling and dilatation process
characteristic of the failing human heart.
