Research Abstract

Bach1 is a stress-responsive transcriptional factor that orchestrates the expression levels of cytoprotective factors, including heme-oxygenase (HO)-1. In the present study, we investigated the effect of suppression of Bach1 expression on cardiac remodeling after myocardial infarction and limb ischemia in mice. Adverse cardiac remodeling and fibrosis after myocardial infarction was significantly attenuated in Bach1-deficient mice. Intramuscular administration of siRNA against Bach1 accelerated blood flow perfusion and capillary density in a hindlimb ischemia model. These results suggest that Bach1 expression can be a therapeutic target in ischemic cardiovascular diseases.
