This study reinforces the importance of considering the rat strain selected when interpreting data given that the Sprague-Dawley rats injected with 50 mg NMU/kg BW at 42 days of age showed a lower tumor incidence and tumor burden than the Wistar-Furth rats used in our study.
The Wistar Kyoto (WKY) rat has been proposed as an animal model of depressive behavior and exhibits hyper-responsiveness to stressful stimulation when compared to other rat strains.
Similar results were obtained when effector cells from other rat strains were used (see below Fig. 7).
The inbred rat strains Lewis (LEW) and Spontaneously Hypertensive Rats (SHR), when compared with each other, display high and low basal indices of anxiety-related behaviors, respectively, when tested in classical anxiety models.
These results suggest that differences between the Roman rat strains in consummatory contrast paradigms can only be observed when the sucrose solution manipulation implies an incentive loss-attenuated emotional situation, but not when it occurs in an anticipatory manner.
However, no difference in PPARGC1A expression was found when comparing islets from F344 or GK rat strains (Fig. 3b).
The control strain is usually the Wistar Kyoto Rat (WKY) as this rat is the progenitor strain and its behavior is closely similar to that of other strains when tested in operant tasks [ 17].
The control strain is usually the Wistar Kyoto Rat (WKY) as this rat is the progenitor strain and its behavior is closely similar to that of other strains when tested in well-controlled operant tasks [ 20].
The control group is usually the Wistar Kyoto Rat (WKY) as this rat is the progenitor strain and its behavior is closely similar to that of other strains when tested in well-controlled operant tasks [ 8, 9].
When treated with estradiol at a standard dosage, certain rat strains rapidly develop breast cancer almost without exception (Shull et al, 1997; Harvell et al, 2000).
