To analyze direct effects of steroids on the rates of synthesis (and/or degradation) of newly synthesized proteins of the rat heart, we have used high resolution two-dimensional gel electrophoresis and autoradiography. A collective steroid domain of nineteen proteins, comprising fifteen with an increased rate of synthesis and four with a decreased rate of synthesis, was consistently seen in cultures of cardiac muscle and non-muscle cells from neonatal rats following 24 h incubation with 10(-7) dexamethasone. Similarly, incubation with 10(-7) M sex steroids, mineralocorticoids, and other glucocorticoids including the highly selective compound RU26988, established the glucocorticoid-specificity of the response. Different subsets of this glucocorticoid domain were seen for collagenase- or trypsin-dispersed primary cultures of cardiac muscle and non-muscle cells or for passaged cultures of cardiac non-muscle cells. Six polypeptides were consistently induced in all cardiac cultures, regardless of cell morphology. Two polypeptides were consistently induced only in those cultures containing cardiac non-muscle cells, whereas protein l, of identical Mr(approximately 52K) and pI (approximately 5.3) to desmin, was induced only in cultures of spontaneously contractile cardiac muscle cells. The glucocorticoid domain proteins described herein represent direct steroid effects on cardiac cells and are therefore candidate mediators of physiological glucocorticoid effects on, for example, differentiation and contractility.
