Background strainDDD
Strain developmentAccording to Tanaka Matsuzawa (1990) "Inbreeding of dd mice maintained at Denken was commenced in 1957 and the resulting inbred strain was named DDD after dd at Denken. The ancestors of dd mice had come from Germany.F164
Strain descriptionMammary tumours 8% at 14 months in virgin and 14% at 14 months in force-bred females. Mammary tumour virus carried by the strain is probably of plaque-inducing group found in DD, RIII and BR6 but not in C3H (Matsuzawa et al., 1974., 1974). Develop a high incidence of heritable hydronephrosis, with a higher incidence observed in males and females. This appears to be caused by an abnormally high internal pressure in the renal pelvis leading to incomplete protection against the vesico-urethral reflex (Mannen et al 1991). Host of a very stable, transplantable pregnancy-dependent mammary tumour TPDMT-4 (Matsuzawa and Yamamoto, 1975). Resistant to the development of uterine tumours following treatment with DMBA at 4-weeks of age (cf 3/6) (Tsubura et al, 1993). High incidence of lethality among F1 Dh/+ male mice resulting from a cross between DDD females and DH-Dh/+ males, however, this is not observed in the reciprocal cross (Suto et al, 1996).
