Genes influencing spinal bone mineral density in inbred F344, LEW, COP, and DA rats [PDF]
Functional & Integrative Genomics, 2009 Previously, we identified the regions of chromosomes 10q12-q31 and 15p16-q21 harbor quantitative trait loci (QTLs) for lumbar volumetric bone mineral density (vBMD) in female F2 rats derived from Fischer 344 (F344) x Lewis (LEW) and Copenhagen 2331 (COP) x Dark Agouti (DA) crosses.

Quantitative studies of lymphoid organs, blood and lymph in inbred athymic and euthymic LEW rats under germfree and specified-pathogen-free conditions [PDF]
Laboratory Animals, 1987 Four groups of inbred male LEW rats were examined: A, germfree athymic; B, specified pathogen free (SPF) athymic; C, germfree euthymic; D, SPF euthymic. All animals were killed at 18 weeks and compared with respect to body weight, histological appearance and cell density of the lymphoid organs, haematological values and differential counts of bone ...

Effects of Homozygosity of the nude (rnu) gene in an inbred strain of rats: Studies of lymphoid and non-lymphoid organs in different age groups of nude rats of LEW background at a stage in the gene transfer [PDF]
Laboratory Animals, 1984 Several age groups of nude homozygous rnu/rnu and heterozygous rnu/+ rats of the same genetic background at an early stage of back-crossing (LEW/Mol) were compared as to body and organ weights, histological appearance and cell density of lymphoid organs, haematological values and differential counts of bone marrow and peripheral blood.

Experimental and Toxicologic Pathology, 1995 Although Lewis rats are frequently used in biomedical research, little is known about their life-data and spontaneous pathology. Therefore, it was the aim of this study to determine the life expectancy, spectrum and incidence of spontaneous neoplasms of the inbred rat strain LEW/Han.

Genomics, 2004 We recently identified a single-nucleotide polymorphism in the Ncf1 gene, a component of the NADPH oxidase complex, to be the cause of one of the strongest identified loci for arthritis severity in rats. This polymorphism was found to be naturally occurring in a collection of inbred rat strains as well as in wild rats. Among the inbred strains we found

Nest-building behaviour in male rats from three inbred strains: BN/HsdCpb, BDIX/Or1Ico and LEW/Mol
Animal Welfare, 2005 AbstractThree inbred strains of male laboratory rat (BN/HsdCpb, BDIX/Or1Ico and LEW/Mol) were provided with nest boxes and nest materials, and were observed for nest-building activity. After 7 days, each cage and nest box was examined. Each nest was weighed and scored for complexity, and returned to the cage.

Frontiers in Behavioral Neuroscience, 2022 Genetic background and age at first exposure have been identified as critical variables that contribute to individual vulnerability to drug addiction. Evidence shows that genetic factors may account for 40–70% of the variance in liability to addiction ...

Low-anxiety rat phenotypes can be further reduced through genetic intervention. [PDF]
PLoS ONE, 2013 BACKGROUND: A previous study using an intercross between the inbred rat strains Lewis (LEW) and Spontaneously Hypertensive Rats (SHR) identified a locus on chromosome 4, named Anxrr16, influencing an experimental index of anxiety and showing a ...

A variable CD3⁺ T-cell frequency in peripheral blood lymphocytes associated with type 1 diabetes mellitus development in the LEW.1AR1-iddm rat. [PDF]
PLoS ONE, 2013 PURPOSE: The LEW.1AR1-iddm rat is an animal model of human type 1 diabetes mellitus (T1DM), which arose through a spontaneous mutation within the MHC-congenic inbred strain LEW.1AR1 (RT1(r²)).

N-octanoyl-dopamine is an agonist at the capsaicin receptor TRPV1 and mitigates ischemia-induced [corrected] acute kidney injury in rat. [PDF]
PLoS ONE, 2012 Since stimulation of transient receptor potential channels of the vanilloid receptor subtype 1 (TRPV1) mitigates acute kidney injury (AKI) and endogenous N-acyl dopamine derivatives are able to activate TRPV1, we tested if synthetic N-octanoyl-dopamine ...
