Abstract:
Polymorphisms that have been proven to influence gene functions are called functional polymorphisms. It is significant to know the distribution of functional polymorphisms in the rat, widely used in animal models for human diseases. In this study, we assessed 16 functional polymorphisms consisting of 3 coat color and 13 disease-associated genes in 136 rat strains, as a part of the genetic profiling program of the National Bio Resource Project for the Rat (NBRP-Rat).

Abstract:
Rat remains a major biomedical model system for common, complex diseases. The rat continues to gain importance as a model system with the completion of its full genomic sequence. Although the genomic sequence has generated much interest, only three complete sequences of the rat mitochondria exist. Therefore, to increase the knowledge of the rat genome, the entire mitochondrial genomes (16,307–16,315 bp) from 10 inbred rat strains (that are standard laboratory models around the world) and 2 wild rat strains were sequenced. We observed a total of 195 polymorphisms, 32 of which created an amino a

1. A structural alteration within the first intron of the renin gene in spontaneously hypertensive rats was demonstrated to co-segregate with blood pressure in some sets of F2 hybrids or recombinant inbred strains.

For this reason we have determined renal renin activity in spontaneously hypertensive, Wistar-Kyoto and Brown Norway rats as well as in 22 recombinant inbred strains derived from F2 hybrids of spontaneously hypertensive and Br

Abstract:
The responses of inbred heat-tolerant FOK rats to cold were compared with those of Wistar King A/H (WKAH) and Std:Wistar (WSTR) strains. The fall of colonic temperature during cold exposure was unexpectedly smaller in FOK than in other groups, but the onset of shivering was delayed in FOK. Norepinephrine (NE)-induced in vivo oxygen consumption and the mitochondrial uncoupling protein 1 level of brown adipose tissue (BAT) were not different among the groups, but the cold-induced increases in in vivo oxygen consumption as well as plasma glycerol and free fatty acids were higher in FOK than in ot

Abstract:
To find a genetic basis for differential ability to survive severe hemorrhage, we previously showed eightfold differences in survival times among inbred rat strains. We assumed that rat strains had similar normalized blood volumes (NBV; ml/100 g body wt). As NBV might vary among strains and constitute one genetic variable affecting survival time to hemorrhage, in experiment 1 of the current studies we first measured total blood volumes and calculated NBV in specific inbred rat strains (Brown Norway/Medical College of Wisconsin, BN; Dark Agouti, DA; Fawn Hooded Hypertensive, FHH; Lewis, LEW; an

Abstract:
There is a need to develop new and more consistent animal models of cardioprotection. Traditionally, outbred dogs, rabbits, and rats have been studied. We determined resistance to ischemia in isolated hearts from inbred strains of rats. Hearts from inbred rats: SS/Mcw (Dahl S, Dahl salt-sensitive), DA/Hsd (Dark Agouti), LEW/Hsd (Lewis), and BN/SsN/Mcw (Brown Norway); and from an outbred rat: Hsd:WIST (Wistar) were subjected to 27 min of global, no-flow ischemia, followed by 3 h of reperfusion. Infarct size in the Brown Norway rat was 2.5 times less than that observed in the Dahl S rat, with th

Abstract:
In this report, we performed parabiosis surgery on inbred Lewis rats and showed that rat kidney resident macrophages (KRMs), identified using our novel cross-species markers, are minimally dependent on peripheral blood input. Thus, for the first time, to our knowledge, we confirm that a hallmark of mouse KRMs is also present in KRMs isolated from another species.

Abstract:
It has been reported that there is a striking homology between the basic insulin-like growth factors (IGF) – somatomedins (SM) found in humans and rats. The radioimmunoassay (RIA) developed for the human hormone IGF-I (basic somatomedin, B-SM) can measure immunoreactive IGF-I in rat serum (IrIGF-I). Using this RIA, the profile of serum IrIGF-I was measured at each day of gestation in groups of inbred and Charles River Wistar rats. In each case IrIGF-I showed a gradual increase in early and mid gestation followed by a sharp decrease that occurred late in gestation to values 20–40% of control. T

The rat possesses a hemochorial form of placentation. Pronounced intrauterine trophoblast cell invasion and vascular remodeling characterize this type of placentation. Strain-specific patterns of placentation are evident in the rat. Some rat strains exhibit deep intrauterine trophoblast invasion and an expanded junctional zone [Holtzman Sprague-Dawley (HSD), Dahl salt sensitive (DSS)], whereas placentation sites of other rat strains are characterized by shallow invasion and a restricted junctional zone [Brown Norway (BN)].

Abstract. Despite extensive research conducted over the past century, the mechanisms of compensatory renal growth (CRG) remain a mystery. Insight into the mechanisms that regulate CRG might be gained by identifying genetic factors that influence this complex phenotype. In a large set of recombinant inbred strains derived from the spontaneously hypertensive rat and the Brown Norway rat, a genome scan for quantitative trait loci (QTL) that regulate CRG was performed. The CRG score was expressed as a ratio of the weight of the remnant right kidney at 8 wk of age to the weight of the left kidney a

Dose-response curves to inhaled aerosolized methacholine chloride (MCh) were obtained in anesthetized spontaneously breathing rats. Thirty rats (10/strain), randomly selected from highly inbred ACI, Lewis (L), and Brown Norway (BN) strains and 40 rats (20/strain) from similarly inbred Wistar-Furth (WF) and Buffalo (Buf) strains were studied. Airway responses were quantitated from changes in pulmonary resistance (RL) and airway reactivity was calculated as the dose of MCh required to increase RL to 150% (ED150RL) and 200% (ED200RL) of base line.
