Alpha-adrenergic activation upregulates expression of relaxin receptor RXFP1 in cardiomyocytes

Ann N Y Acad Sci. 2009 Apr:1160:285-6. doi: 10.1111/j.1749-6632.2008.03791.x.

Abstract

Cardiac RXFP1 was upregulated upon activation of the alpha(1)-adrenergic receptor (AR) through signal pathways involving protein kinase A and C and ERK. In contrast, beta(1)-AR activation downregulated expression of cardiac RXFP1 and it further counteracted the alpha(1)-AR-mediated RXFP1 upregulation.
