Secretion of atrial natriuretic factor-(1-98) by primary cardiac myocytes.

Previous studies have demonstrated that primary cultures of cardiac myocytes maintained in a complete serum-free medium contain a precursor to atrial natriuretic factor (ANF-(1-126]. The cultured cells secrete this precursor unless maintained in the …

Adrenocorticotropin(1-14)OH-related molecules in primary cultures of rat intermediate pituitary cells. Identification and role in the biosynthesis of alpha-melanotropin.

The structures of the altered alpha-melanotropin (alpha MSH or alpha-N-acetyl-ACTH(1-13)NH2)-related molecules produced by cultured rat intermediate pituitary cells were investigated. Peptide analyses demonstrated that the alpha MSH-related molecules …
