Exaggeration of focal cerebral ischemia in transgenic mice carrying human Renin and human angiotensinogen genes.
BACKGROUND AND PURPOSE We examined the possibility that activation of the human brain renin-angiotensin system is involved in enhancement of ischemic brain damage using chimeric transgenic mice with human renin (hRN) and human angiotensinogen (hANG) genes. METHODS Chimeric (hRN/hANG-Tg) mice were generated by mating of hRN and hANG transgenic mice. Permanent occlusion of the middle cerebral a...
متن کاملAppropriate regulation of renin and blood pressure in 45-kb human renin/human angiotensinogen transgenic mice.
The renin-angiotensin system is normally subject to servo control mechanisms that suppress plasma renin levels in response to increased blood pressure and increase plasma renin levels when blood pressure falls. In most species, renin is rate limiting, and angiotensinogen circulates at a concentration close to the Km, so varying the concentration of either can affect the rate of angiotensin form...
متن کاملCerebral arteriolar structure in mice overexpressing human renin and angiotensinogen.
We examined the hypothesis that the renin-angiotensin system plays an important role in vascular remodeling (defined as reduced external diameter) during chronic hypertension. We measured pressure, diameter, and cross-sectional area of the vessel wall in maximally dilated cerebral arterioles in transgenic mice that overexpress both human renin and human angiotensinogen and in spontaneously hype...
متن کاملIschemia-induced brain damage is enhanced in human renin and angiotensinogen double-transgenic mice.
To investigate the role of brain angiotensin II (ANG II) in the pathogenesis of injury following ischemic stroke, mice overexpressing renin and angiotensinogen (R+A+) and their wild-type control animals (R-A-) were used for experimental ischemia studies. Focal brain ischemia was induced by middle cerebral artery occlusion (MCAO). The severity of ischemic injury was determined by measuring neuro...
متن کاملPressure-natriuresis and -diuresis in transgenic rats harboring both human renin and human angiotensinogen genes.
The hypertensive double transgenic rat harboring both the human renin and human angiotensinogen genes (dTGR) offers a unique opportunity to study the human renin-angiotensin system in an experimental animal model. Since nothing is known about the control of sodium and water excretion in these rats, this study was performed to compare pressure-natriuresis relationships in hypertensive dTGR and n...
