Inbred Strains
of Mice: MA
Inbr (J): 132. Albino. Genet.
c. Origin: Marsh's strain 3. Started
from a pair of mice from the Lathrop-Loeb colony (1903-1915). 32 generations
of cousin mating by Marsh, to W.S.Murray who started b x s (
Murray
1963).
Characteristics
Primary lung tumours 37% in males, 42% in females. Lymphatic leukaemia
1% in males and breeding females, zero in virgin females. Mammary tumours
zero (
Hoag, 1963). Low gross tumour incidence
(22/22) (
Storer, 1966). Polydipsia-polyuria
(
Bernstein, 1966), which may be associated
with cysts pressing on posterior lobe of pituitary (
Russell and Meier, 1966). Life-span intermediate in both
sexes (7/22 = 459 days in males, 12/22 = 585 days in females) (
Storer,
1966).
\par
High metabolic rate (3/18) (Storer, 1967). High
plasma cholinesterase activity in females (4/22) but low in males (18/22)
(Angel et al., 1967., 1967). Low liver
arylsulphatase activity (11/12) (Daniel, 1976).
Only strain out of 29 tested that carries the mannosephosphate isomerase
Mpi 1a allele (Nichols et al., 1973., 1973).
\par
Small spinal cord (23/25) (Roderick et al.,
1973., 1973). Large kidney/body weight ratio (4/21) (Schlager,
1968). Large hippocampus (2/9) (Wimer et
al., 1969., 1969). Fusion between left part of median lobe and left
lateral lobe of liver is common (Bunker, 1959).
\par
Resistant to X-irradiation (2/27 in J substrain, 7/27 in My substrain)
(Roderick, 1963). Resistant to pulmonary hyaline-membrane
formation (1/10) and long survival in 90% oxygen (3/10) (Lieberman and Kellog, 1967).
\par
Highly susceptible to the mammary tumour virus, which is not normally
carried by the strain (Murray and Little,
1967).
