Integration of genome-wide expression profiling with linkage analysis is a new approach to identifying genes underlying complex traits. We applied this approach to the regulation of gene expression in the BXH/HXB panel of rat recombinant inbred strains, one of the largest available rodent recombinant inbred panels and a leading resource for genetic analysis(More)
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)
Spontaneously hypertensive rats (SHR) display several features of the human insulin-resistance syndromes. Cd36 deficiency is genetically linked to insulin resistance in SHR. We show that transgenic expression of Cd36 in SHR ameliorates insulin resistance and lowers serum fatty acids. Our results provide direct evidence that Cd36 deficiency can promote(More)
Germline transgenesis is an important procedure for functional investigation of biological pathways, as well as for animal biotechnology. We have established a simple, nonviral protocol in three important biomedical model organisms frequently used in physiological studies. The protocol is based on the hyperactive Sleeping Beauty transposon system, SB100X,(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)
Pioglitazone, like other thiazolidinediones, is an insulin-sensitizing agent that activates the peroxisome proliferator-activated receptor gamma and influences the expression of multiple genes involved in carbohydrate and lipid metabolism. However, it is unknown which of these many target genes play primary roles in determining the antidiabetic and(More)
Recently, the relationship of mitochondrial DNA (mtDNA) variants to metabolic risk factors for diabetes and other common diseases has begun to attract increasing attention. However, progress in this area has been limited because (1) the phenotypic effects of variation in the mitochondrial genome are difficult to isolate owing to confounding variation in the(More)
OBJECTIVES Telmisartan is an angiotensin II receptor blocker and selective modulator of peroxisome proliferator-activated receptor-gamma reported to increase energy expenditure and improve glucose and lipid metabolism compared with other angiotensin II receptor blockers. As muscle fatty acid oxidation is a major determinant of energy expenditure, we(More)
To identify renally expressed genes that influence risk for hypertension, we integrated expression quantitative trait locus (QTL) analysis of the kidney with genome-wide correlation analysis of renal expression profiles and blood pressure in recombinant inbred strains derived from the spontaneously hypertensive rat (SHR). This strategy, together with renal(More)
The pig has emerged as an important large animal model in biomedical and pharmaceutical research. We describe a protocol for high-efficiency germline transgenesis and sustained transgene expression in pigs by using the Sleeping Beauty (SB) transposon system. The protocol is based on co-injection of a plasmid encoding the SB100X hyperactive transposase,(More)
