1Edward Mallinckrodt Department of Pediatrics, Washington University School of Medicine, St. Louis, MO 63110.
Insights
Newly discovered cardiac-derived peptides, atriopeptins, play a role in blood pressure regulation. Altered levels in human disease suggest potential as a therapeutic for hypertension and volume overload.
Area of Science:
- Cardiovascular Physiology
- Endocrinology
- Nephrology
Background:
- Atriopeptins are novel peptides originating from the heart.
- Their functions suggest involvement in maintaining fluid balance and controlling blood pressure.
Purpose of the Study:
- To investigate the role of atriopeptins in volume homeostasis and blood pressure regulation.
- To explore the potential of atriopeptins in managing hypertension and volume overload.
Main Methods:
- Animal models are used to study the development of hypertension.
- Circulating atriopeptin levels are being assessed in human diseases.
Main Results:
- Observed actions of atriopeptins indicate a role in cardiovascular regulation.
- Preliminary data show altered atriopeptin levels in patients with certain diseases.
Conclusions:
- Atriopeptins are implicated in the physiological control of blood pressure and fluid balance.
- Exogenous atriopeptin administration may offer a new therapeutic strategy for hypertension and volume overload.
Abstract:
The atriopeptins are newly discovered cardiac-derived peptides whose observed actions suggest a role in volume homeostasis and blood pressure regulation. Studies in animal models are underway to pinpoint pathogenetic mechanisms involved in the evolution of hypertension, some of which may well be shared by humans with "essential" hypertension. Preliminary observations indicate that circulating atriopeptin levels are altered in human disease. It is anticipated that exogenously administered atriopeptin may be a helpful pharmacological tool in the management of patients with volume overload and hypertension.
