Cadiac GATA-4 overexpression in vivo


ABSTRACT: The objective of the study was to find cardiac GATA-4 target genes by overexpressing GATA-4 transcription factor in the left ventricle by adenoviral gene transfer. Gene expression profiles three days after GATA-4 gene transfer were compared with those of Lac Z –treated animals by screening Affymetrix Rat Expression Set 230_2.0 Arrays (there are 5 samples in both group). Strain:Sprague-Dawley; Gender, Male; Weight 250-300g; tissue, left ventricle.

<h4>Background</h4>Recent data suggest that GATA-4 is an antiapoptotic factor required for adaptive responses and a key regulator of hypertrophy and hypertrophy-associated genes in the heart. As a leading cause of chronic heart failure, reversal of postinfarction left ventricular remodeling represents an important target for therapeutic interventions. Here, we studied the role of GATA-4 as a mediator of postinfarction remodeling in rats.<h4>Methods and results</h4>Myocardial infarction, caused b  ...[more]
