Strain differences in the response of the mouse to diethylstilbestrol. 1977

D L Greenman, and K Dooley, and C R Breeden

BALB/c StCrlfC3Hf/Nctr, C57BL/6/, C57BL/6 X BALB/c F1 hybrid (B6CF1), and monohybrid-cross offspring from the breeding of B6CF1 mice were examined with respect to uterine, vaginal, and thymus responses to diethylstilbestrol (DES). About 400 mice of each genetic population were used. Weanling mice were fed DES at dietary concentrations of 2.5 to 1,000 ppb (microgram/kg feed) for 6 days and were killed by cervical dislocation about 20 hr after removal of the feed. C57BL/6, B6CF1, and the monohybrid-cross offspring did not differ in the uterine-weight response to DES, but the slope of the dose-response line was shallower for the BALB/c than for the other strains. Dietary DES concentrations of 250 ppb or more inhibited the uterotrophic response in all populations. Vaginal cornification occurred at lower concentrations of DES in the C57BL/6 strain than in the B6CF1 animals. BALB/c and monohybrid-cross offspring were indistinguishable from each other in their vaginal response to Des and were less sensitive to DES than the other mouse populations. The use of ethanol or corn oil as the solvent for mixing DES into the diet had no apparent effect on the uterine weight or vaginal response in any of the mice. DES depressed thymus weight in a dose-related fashion at dietary concentrations of 100 ppb and above in all genetic populations.

D008810	Mice, Inbred C57BL	One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D008815	Mice, Inbred Strains	Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations, or by parent x offspring matings carried out with certain restrictions. All animals within an inbred strain trace back to a common ancestor in the twentieth generation.

D004054	Diethylstilbestrol	A synthetic nonsteroidal estrogen used in the treatment of menopausal and postmenopausal disorders. It was also used formerly as a growth promoter in animals. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), diethylstilbestrol has been listed as a known carcinogen.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
