Dr. A.J. de Bold is Professor of Pathology and Physiology and Director of the Cardiovascular Endocrinology Laboratory at the University of Ottawa Heart Institute. This laboratory is located in modern facilities within the Research Centre of the Heart Institute, a 100,000 sq ft facilities complete with conference and animal facilities.

Dr. de Bold's research developed from his discovery of the endocrine function of the heart and the cardiac hormone ANF. The laboratory provides opportunities to work in daily contact with three senior scientists, graduate and post-doctoral students as well as with other students from the various research groups. Laboratory journal clubs are held weekly and scientific as well as clinical conferences are held several times a week through the different activities of the Heart Institute. Our general approach to scientific problems aims at maintaining an integrated view of cardiovascular physiology and pathophysiology even in those areas where we investigate at the molecular level.

Current fields of interest include: 1. Transcriptional and posttranscriptional control of natriuretic peptide production (ANF, BNP) by the endocrine heart, protein trafficking and sorting of cardiac polypeptide hormones. 2. Endocrinology of congestive heart failure with special reference to cytokines. 3. Aldosterone production by the heart and, 4. Development of monoclonal antibodies and other activities related to the production of tests for diagnosis of cardiac disease.

Technically, the Laboratory is proficient in a broad spectrum of many modern and classical techniques including light and electron microscopy, immunohistochemistry, various biochemical and molecular biology techniques and both in vivo and in vitro preparations as well as cell culture systems. Our students receive a well rounded technical training, often beyond the requirements of their specific projects.

Current research is funded by three grants from CIHR and one grant from the OHSF.
