Strain Registration

Strain: DA

Symbol: DA
Strain: DA
Full Name: DA
RGD ID: 60997
Citation ID: RRID:RGD_60997
Ontology ID: RS:0000014
Alleles: Tnfrsf1a;   Ednrb
Type: inbred
Available Source: Not Available
Description: Developed from stock of unstated origin by Dr. T.T. Odell, Jr. at Oak Ridge National Laboratory, Tennessee to F11, then by Dr. Darcy Wilson at the Wistar Institute, who named it DA because it expressed the 'd' blood group allele of Joy Palm, and it is 'a' agouti in colour (Wilson 1965). Inbreeding was completed in about 1965. Although Palm and Black (1971) suggest it may be related to COP, there is no real evidence that this is the case.
Genetic Markers: A,C,H.
Coat Color: Agouti .
Inbred Generations: F77 (Han1989)
Last Known Status: Unknown

strain_drgs_chems Rats developed mild arthritis after injected with IFA emulsified with water but when arthritogenic adjuvants like pristane, mycobacteria, MDP, avridine were added arthritis incidence was increased from 50% to 100% and severity from 4-7 to 10-12. Beta glucan solution was able to induce arthritis when injected without IFA. 737660
strain_immunology Susceptible to the induction of autoimmune thyroiditis (Rose 1975). Develop severe collagen-induced arthritis following immunisation with bovine, chick or rat type II collagens. This is exacerbated by infection with rat cytomegalovirus. However, the congenic strain DA.1N(BN) is much more resistant (Griffiths et al, 1994). Develops arthritis after injection of Freunds incomplete adjuvent alone (oil-induced arthritis, OIA). This is a self-limiting acute disease whereas collagen-induced arthritis follows a chronic course (Holmdahl and Kvick, 1992, 1994). DA is sensitive whereas LEW are relatively resistant (Holmdahl et al, 1992). A strong local expression of TNF-alpha, induced by arthritogenic stimuli may be important for the induction of arthritis (Mussener et al, 1995). Susceptible to the development of experimental allergic encephalomyelitis upon treatment with a myelin basic protein-specific T cell line derived from an F1 hybrid between resistant AO and susceptible DA strain rats (Mostaricastrojkovic et al, 1992). Although DA andLEW are both highly susceptible to the development of EAE, there are marked differences in the array of myelin epitopes capable of inducing the disease as well as MHC restriction of these epitopes between the two strains (Stepaniak et al, 1995). Resistant to the development of experimental glomerulonephritis following injection of nephritogenic antigen from bovine renal basement membrane (10/10) (Naito et al, 1991).Met-enkephalin increased H2O2 production by macrophages (contrast AO) (Radulovic et al,1995). 1004

strain_phys_biochem Possible model for deficiency of debrisoquine hydroxylation due to a lack of Cyp2D1 activity,which is equivalent to human Cyp2D6 (Al-Dabbagh et al 1981), with the defect being due to a structurally altered db1 protein (Gonzalez et al 1987). At least one other isoform of P450 of the Cyp2C or Cyp3A families may also be missing. Although DA rats may be used as a preliminary screen to identify Cyp2D6 substrates, interspecies differences in metabolism means that this strain could not be used to provide quantitative information regarding the contribution of Cyp2D6 to anoxidation in humans (Barham et al, 1994) Defective bile acid transport found in females, which may be related to deficient debrisoquine hydroxylation (Reichen et al 1986). Hackbarth et al (1981) have described the glomerular filtration rate and renal plasma flow in DA and other strains, and haematological parameters and their relation to diet have been described by Hackbarth et al (1983). In studies of food intake andbody weight gain, DA rats ingested mainly proteins and fats, in contrast with outbred Wistar rats which ate about equal quantities of fat, protein and carbohydrate (Larueachagiotis et al, 1994). 1004
