The atrial natriuretic peptide (ANP) hormone is secreted by cardiac atrial myocytes and acts to regulate blood pressure homeostasis in humans. Previous research indicates ANP treatment significantly decreases the proliferation of human prostate cancer cells, pancreatic adenocarcinoma, and breast cancer cells. Minimal studies have been conducted with regard to ANP regulating tumor suppressor gen...

Microvascular functions have been shown to be sensitive to agents associated with changes in cyclic nucleotide levels. The central hypothesis of the current study was that one measure of capillary exchange capacity, hydraulic conductivity (Lp), would be elevated by agents shown to elevate cellular levels of cGMP. To evaluate the hypothesis, frog mesenteric capillary Lp was measured during lumin...

Regulation of atrial release of atrial natriuretic peptide (ANP) is coupled to changes in atrial dynamics. However, the mechanism by which mechanical stretch controls myocytic ANP release must be defined. The purpose of this study was to define the mechanism by which cAMP controls myocytic ANP release in perfused, beating rabbit atria. The cAMP-elevating agents forskolin and 3-isobutyl-1-methyl...

In anesthetized rats, the renal excretory actions of atrial natriuretic peptide (ANP) are inhibited by intravenous or intraperitoneal injections of bradykinin. To elucidate the mechanisms underlying this inhibition, we evaluated bradykinin effects on: i- ANP-induced natriuresis and diuresis in isolated perfused rat kidneys, and ii- ANP-induced cGMP production in rat renal medulla in vitro. In p...

It has been shown that renal responses to atrial natriuretic peptide (ANP) are markedly attenuated in patients with heart failure. This study aimed to determine if vasodilative response to ANP is altered in patients with heart failure. In patients with heart failure (n = 7) and age-matched normal subjects (n = 7), forearm blood flow was measured using a strain-gauge plethysmograph during intra-...

Atrial natriuretic peptide (ANP) and its receptors are present in hypothalamic nuclei containing the magnocellular neurosecretory cells (MNCs), which release vasopressin and oxytocin. In the rat, intracerebroventricular injections of ANP inhibit the release of both hormones in response to hypertonicity. Although these findings suggest a role for endogenous ANP in the central control of fluid ba...

The mechanisms that mediate renal "escape" from the sodium-retaining effects of mineralocorticoids are incompletely understood. This study was undertaken to determine whether atrial natriuretic peptide (ANP) may play a role in the escape phenomenon. Immunoreactive ANP in rat plasma increased 2.5-fold above baseline values at 12 and 24 h after a single depot injection of desoxycorticosterone ace...

Atrial natriuretic peptide (ANP) is produced and secreted by atrial cells. We measured calf capillary filtration rate with prolonged venous-occlusion plethysmography of supine healthy male subjects during pharmacologic infusion of ANP (48 pmol/kg/min for 15 min; n = 6) and during placebo infusion (n = 7). Results during infusions were compared to prior control measurements. ANP infusion increas...
