Blood pressure, left ventricular hypertrophy, and expression of TGF-\u03b21 and TGF-\u03b21-regulated genes were investigated. ACE inhibition reduced blood pressure in all groups. When normalised to blood pressure, a significant reduction in hypertrophy was found in ovariectomised animals receiving E2. Expression of TGF-\u03b21 was increased in all three groups treated with the ACE inhibitor, with top levels in ovariectomised animals. Moreover, expression of ornithine decarboxylase (ODC), an adrenoceptor dependent gene, downstream of TGF-\u03b21, was up-regulated upon ACE inhibition, except in animals which were ovariectomised and oestrogen supplemented. Parathyroid hormone-related peptide, a growth factor negatively regulated by TGF-\u03b21, was down-regulated in all animals receiving the ACE inhibitor.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>ACE inhibition modulated TGF-\u03b21 and TGF-\u03b21 dependent genes.
