Inbred Strains of Mice: LG

LG

Inbr (J) 104. Albino. Genet. a,c Origin: Developed by Goodale with selection for large body size begining in 1931 (Chai 1961). Two substrains, J and Ckc were separated at F27. LG/J is H2d, Pgk2b while LG/Ckc is H2ar1, Pgk2a. LG/J should not be confused with MacArthur's large strain which has never been established as an inbred strain and is now extinct.


Characteristics

Mean life-span 491 days (Staats, 1976). About 5% incidence of bent or kinked tails (Dagg, 1966). Low kidney arylsulphatase activity (12/12) (Daniel, 1976). Large brain weight (1/25) and spinal cord (1/25) (Roderick et al., 1973., 1973). High serum complement activity (c.f. 8/26) (Ong et al 1989). Low lymphocyte phyto-haemagglutinin response (41/43) (Heiniger et al., 1975., 1975). Large number of granule cells in right area dentata of brain (1/5) (Wimer and Wimer 1982) Maint. by J. Large body weight which differs from that of the small strain SM/J as a result of about seven quantitative trait loci at one week and 17 loci at 10 weeks of age. Each locus has a small effect (Cheverud et al, 1996).

J substrain develops antinuclear autoantibodies and rheumatoid factor, and develop renal disease including glomerulonephritis, intersticial nephritis and perivasculitis, but not hepatic or cutaneous disease. Strain MRL/Mp has an estimated 75% of genome in common with this strain (Peng et al, 1996).
