Atrial natriuretic peptide gene expression within invertebrate hearts.


:The present investigation was designed to (1) determine if atrial natriuretic factor gene expression occurs within invertebrates as well as within vertebrates; (2) determine whether the product of this gene expression is the 126-amino-acid atrial natriuretic factor prohormone or some other molecular species; and (3) evaluate within the same invertebrates if the products of atrial natriuretic factor gene expression are released into their circulation. Utilizing a very sensitive RNase protection assay it was found that atrial natriuretic peptide gene expression occurs within the heart of the oyster, Crassostrea virginica, and within the heart of the blue crab, Callinectes sapidus, but was expressed sevenfold less than in a vertebrate heart (i.e., rat, Rattus norvegiucs). High-performance gel-permeation chromatography followed by N-terminal and C-terminal atrial natriuretic factor prohormone radioimmunoassays indicated that the molecular species synthesized within the oyster and blue crab hearts was the atrial natriuretic factor prohormone. The product(s) of this atrial natriuretic factor gene expression (i.e., atrial natriuretic peptides) was found to be released into the circulation, i.e., hemolymph, of both the oyster and the blue crab.
