title: Models of experimental hypertension in mice.
abstract: Experimental models of hypertension in various animals are useful in the research of vasoactive mechanisms. Recombinant DNA technology has produced genetically engineered animals, mostly mice, useful in hypertension research. However, the development of hypertensive models in mice is fraught with technical difficulties. We describe here the successful development in mice of two common types of experimental hypertension: the renovascular two-kidney, one clip and mineralocorticoid deoxycorticosterone-salt models. By adapting technology previously used in rats, we succeeded in developing hypertension (defined as systolic pressures higher than 140 mm Hg) in more than 50% of mice so treated. We also adapted the methodology for indirect tail-cuff blood pressure measurements as well as for direct intra-arterial monitoring of blood pressure in conscious, freely moving mice. Application of these techniques in transgenic or gene knockout mice with altered vasoactive hormones or receptors should allow elucidation of the role of the target gene products in various types of hypertension.
