Disorders of carbohydrate and lipid metabolism have been reported to cluster in patients with essential hypertension and in spontaneously hypertensive rats (SHRs). A deletion in the Cd36 gene on chromosome 4 has recently been implicated in defective carbohydrate and lipid metabolism in isolated adipocytes from SHRs. However, the role of Cd36 and chromosome(More)
The spontaneously hypertensive rat (SHR) is the most widely studied animal model of essential hypertension. Despite > 30 yr of research, the primary genetic lesions responsible for hypertension in the SHR remain undefined. In this report, we describe the construction and hemodynamic characterization of a congenic strain of SHR (SHR-Lx) that carries a(More)
The importance of early environment, including maternal diet during pregnancy, is suspected to play a major role in pathogenesis of metabolic syndrome and related conditions. One of the proposed mechanisms is a mismatch between the prenatal and postnatal environments, leading to misprogramming of the metabolic and signaling pathways of the developing fetus.(More)
The HXB/Ipcv and BXH/Cub sets of recombinant inbred (RI) strains were derived from the spontaneously hypertensive rats (SHR/OlaIpcv) and normotensive Brown Norway (BN-Lx/Cub) rats. The RI strains were produced as a model system for genetic and correlation analysis of spontaneous hypertension and other risk factors of cardiovascular disease such as insulin(More)
The SHR and the PD/Cub are two established rodent models of human metabolic syndrome. Introgression of a ca 30 cM region of rat chromosome 8 from PD/Cub onto the genetic background of SHR was previously shown to influence several of the metabolic syndrome-related traits along with causing the PLS in the SHR-Lx congenic strain. In the process of(More)
Genome scan and metabolic profile of the PD/Cub rat inbred strain in comparison with SHR and BN strains is presented. The PD/Cub strain has been bred by brother sister mating for more than 60 generations since 1969. Its highly inbred status has been confirmed by PCR genotyping with more than 170 microsatellite markers. No case of residual heterozygosity has(More)
The airpuff startle reaction is a probe of sensori-autonomic processing and is useful for studies of genetic control of stress-induced cardiovascular activity. Using a Wistar-Kyoto-Spontaneously Hypertensive Rat F2 cross, we reported an airpuff-elicited strain-dependent and trial-dependent bradycardia, the absence of which cosegregated with hypertension.(More)
Lx mutation in SHR.Lx rat manifests in homozygotes as hindlimb preaxial polydactyly. It was previously mapped to a chromosome 8 segment containing the Plzf gene. Plzf (promyelocytic leukemia zinc finger protein) influences limb development as a direct repressor of posterior HoxD genes. However, the Plzf coding sequence is intact in the Lx mutants. Using(More)
It has been proposed that one of the primary events in the development of essential hypertension is a growth-related process initiated as early as during fetal development. Differences in kidney size have been observed between most rat models of hypertension and their respective controls. In this study, we analyzed relative kidney size (kidney weight/body(More)
