Expression and characterization of Edg-1 receptors in rat cardiomyocytes: calcium deregulation in response to sphingosine 1-phosphate.

Recent evidence indicates that sphingolipids are produced by the heart during hypoxic stress and by blood platelets during thrombus formation. It is therefore possible that sphingolipids may influence heart cell function by interacting with …

Dissociation of p44 and p42 mitogen-activated protein kinase activation from receptor-induced hypertrophy in neonatal rat ventricular myocytes.

In response to hormones and mechanical stretch, neonatal rat ventricular myocytes exhibit a hypertrophic response that is characterized by induction of cardiac-specific genes and increased myocardial cell size. Hypertrophic stimuli also activate …

Myocardial alpha-thrombin receptor activation induces hypertrophy and increases atrial natriuretic factor gene expression.

The protease, alpha-thrombin (alpha Th), affects myocardial cell contractility, a feature common among agents that induce hypertrophy. However, it is not known whether cardiac myocytes possess alpha Th receptors (alpha Th-R), or if long term …

Biochemical studies of soluble atrial natriuretic peptide (ANP) receptors from rat olfactory bulb and vascular smooth muscle cells.

1. Aim. The biochemical characteristics of atrial natriuretic peptide receptors (ANP-R) derived from rat vascular smooth muscle (A-10 cell line) and central nervous system (CNS; olfactory bulb) tissue were compared. 2. Method and Results. ANP-Rs from …

Characterization of solubilized atrial natriuretic peptide receptors from rat olfactory bulb and A10 cultured smooth muscle cells.

Atrial natriuretic peptide (ANP) receptors from A10 cultured vascular smooth muscle cells (VSMC) and rat olfactory bulbs have been solubilized and then pharmacologically and biochemically compared. The dissociation constant for 125I-ANP(99-126) was …

Cross-linking of atrial natriuretic peptide to binding sites in rat olfactory bulb membranes.

Binding sites for 125I-atrial natriuretic peptide (ANP)2 in rat olfactory bulb membranes have been studied using pharmacological and biochemical methods. Various unlabeled ANP-related peptides were tested for the ability to inhibit the binding of the …
