The A- and B-natriuretic peptides (ANP and BNP) are the heart major secretory products. ANF and BNP expression is a marker of cardiomyocyte differentiation, and is regulated spatially, developmentally and hormonally. Analysis of the ANP and BNP promoters has contributed in a major way to our present understanding of the key regulators of cardiac development. It has also started to unravel the complex combinatorial interactions required for proper regulation of the cardiac genetic program. The GATA family of transcription factors initially identified as essential regulators of the two natriuretic peptide genes appears to be at the heart of the molecular circuits governing cardiac growth and differentiation. In particular, GATA-4 has emerged as the nuclear effector of several signaling pathways which modulate its function through post-translational modifications and protein-protein interactions. This review will cover our current knowledge of cardiac transcription and the role of GATA factors in embryonic and postnatal heart development.
