We have previously shown that the myocardium is a target tissue for estrogen. Here, we
have identified rapid non-nuclear estrogen effects on the expression of the early growth
response gene-1 (Egr-1) in cardiomyocytes. Egr-1mRNA and protein were rapidly and
strongly induced by estrogen in an estrogen receptor-dependent manner via the
extracellular signal-regulated kinase, ERK1/2. A promoter analysis study of a 1.2-kilobase
Egr-1 promoter fragment revealed that the serum response elements (SREs) but not the …
