Numerous flow-induced genes were revealed by this study, including a group of 8 genes that showed very strong flow induced expression conserved in both inbred strains.A group of 9 genes showed very strong flow induced expression with major differences between an aneurysm prone inbred rats and the aneurysm resistant inbred rats. Characteristics Anatomy After 4 weeks of altered flow, there were significant interstrain differences with respect to the change in carotid outer diameter (OD), the Wistar, Fisher, and Sprague Dawley, and their hundreds of internal divisions, are examples of rat strains. Strains dating back to this time include F344, M520 and Z61 and later ACI . There are multiple strains of rat that are either selected or inbred as models of human pathology. These strains represent all of the commonly used inbred rat strains available from Harlan Sprague-Dawley, excluding strains of rats that are spontaneously hypertensive. inbred rat strain address bn rat dahl rat vasodilator phenotype ss-13 bn rat l diet vascular relaxation mechanism 40-45 mm hg consomic rat impaired renin-angiotensin system normal ra regulation dahl salt restored vasodilation ang ii vascular relaxation high salt diet brown norway ss-16 bn rat renin gene 10-6 mol dahl genetic background po2 . 1999).

Inbred Lewis and Fischer 344 rat strains differ not only in novelty- and amphetamine-induced behaviors, but also in dopamine transporter activity in vivo Abstract Inbred Lewis (LEW) and Fischer 344 (F344) rats are differentially sensitive to drugs of abuse, making them useful for studying addiction-related neural mechanisms. jfrohlich23.

Dose-dependent increases in locomotor activity were found for both drugs in all strains. The advantage of using inbred animals for genetic studies is that essentially all . Inbred Strains are produced by brother x sister mating for 20 or more consecutive generations, and individuals of the strain can be traced to a single ancestral pair at the 20th or subsequent generation. Igaku & Yakugaku 4 (5):599-606,1980. An inbred strain is defined as the product of over 20 generations of brother-sister matings, which results in individuals that are 98% identical to each other. In 1924, at F20 to Aptekman and Bogdon. Rats, Inbred Strains "Rats, Inbred Strains" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings).

There is now considerable background information on strain characteristics, including life-span, spontaneous diseases and response to chemicals. To test the impact of genetic heterogeneity on cis- and trans-mediated mechanisms of gene expression regulation, we profiled the transcriptome of adipose tissue in 20 inbred congenic strains derived from diabetic Goto-Kakizaki (GK) rats and Brown-Norway (BN) controls, which contain well-defined blocks (1-183 Mb) of genetic polymorphisms, and in 123 genetically heterogeneous . Inbred rat strains are produced by breeding related individuals, primarily brother by sister, for at least 20 consecutive generations.

(Japanese) In contrast, only a few strains being inbred by definition (see below) are available for hamsters. Here, we investigated whether strain differences in dopamine transporters (DATs) in dorsal striatum (dSTR) and/or nucleus accumbens (NAc) may help to explain their behavioral .

WNIN (Wistar/NIN) is an inbred rat strain maintained at National Institute of Nutrition (NIN) for more than 90 years, and WNIN/Ob is an obese mutant originated from it. Joe Yeyo Aden. Vaginal distension (VD) in outbred rats has been shown to decrease urethral resistance, as well as increase the expression of the stem cellhoming chemokine, monocyte chemotactic factor 3 (MCP3), but not stromal derived factor 1 (SDF1). Data display is managed using TreeView's radial tree function. 5. The official designation for a rat strains is a unique, brief symbol made up of letters or a combination of letters and numbers, and a laboratory code. Descriptors are arranged in a hierarchical structure, which enables searching at various levels of specificity. Outbred rat models are used in preclinical research to mimic genetic variation in humans. Inbreeding of R rats was started at the Penrose Re- Created by. The definition of inbred strains is valid first of all for rats and mice. Many thousands of papers are published each year involving inbred mouse and rat strains. Four inbred strains differed greatly in their response to a standard inoculation of rat thyroid extract with complete Freund's adjuvant and pertussis vaccine.

Inbred rat strains may be useful in the development of physiological and biochemical models to study the genetic basis of ECM composition and IEL rupture in the rat aorta. Phylogenetics of rat inbred strains. mutant strain + An analysis of interstrain variation between 12 inbred and 4 congenic rat strains in the expression of immunity against Trichinella spiralis is reported. We refer to the strains as SHR and BN-Lx in this paper. 2000).It was soon recognized that inbred strains were of value in many areas of research. This produces a situation where particular alleles can be examined on a collage of backgrounds composed of the genomes of the progenitors. Spell. . This is the fifth listing and has been substantially revised, although it is heavily dependent on previous listings (Festing and Staats, 1973). In 1958, at F31 to Silvers, who distributed this strain subsequently. By Southern blot hybridization with core sequence of minisatellite DNA as a probe, typical hypervariable patterns of DNA fingerprint were obtained in inbred rat strains. These rodents have short-generation intervals and sufficient numbers of offspring to allow the application of close inbreeding. A list of inbred strains and their characteristics is maintained on the Jackson Laboratory web site. F1 and F2 generations are produced by intercrossing the inbred strains; pairs of the F2 progeny are then mated to establish inbred strains through long-term inbreeding. Behavioral effects of chronic exposure to low concentrations of halothane during development in rats. The first listing of inbred strains of rats was by Billingham and Silvers (1959). We show that both male and female STA rats display robust and sustained reductions in periorbital thresholds to cutaneous mechanical stimulation. Phylogenetics of rat inbred strains Mamm Genome. The alcohol preference ratios and the daily free-choice ethanol intakes (10% ethanol versus water) of the newly constituted National Institutes of Health (NIH) heterogeneous stock (N/Nih) rats, and of the eight inbred strains from which N/Nih derived, were measured. These genetic variants of rat MSY may influence similar genes as those involved in human disease or MSY evolu-tion throughout speciation, allowing researchers to nar-row down the large human haplotype block to individual Gravity. By ligating the left internal and external carotid arteries, we caused a 90% decrease in left common carotid blood flow and a 50% increase in right (contralateral) common carotid flow. This study examined the effects of cocaine or amphetamine on locomotor activity in rats from the ACI, F344, LEW and NBR inbred strains. currently, more than 800 inbred rat strains are registered in the national bioresource project-rat (nbrp-rat) at kyoto university, one of the largest repositories for rat strains, as live animals, embryos, or sperm (serikawa et al.
