title: Evidence for an intrinsic angiotensin system in the canine pancreas.
abstract: Increasing evidence suggests an association between hypertension and abnormalities of glucose metabolism. Since components of the renin-angiotensin system exist in a variety of tissues consistent with paracrine actions of the peptide, we sought to determine whether the pancreas contains a local angiotensin system. We report the presence of angiotensinogen messenger (m) RNA, angiotensinogen protein, angiotensin II and high-affinity binding sites for angiotensin II in the canine pancreas. These novel findings establish a foundation for future studies to evaluate whether angiotensin acts as a paracrine regulator of endocrine and/or exocrine functions of the pancreas.
