In some rat strains chronic administration of exogenous estrogens induces pyometritis, an inflammation of the uterus associated with infection, suggesting that there is genetic variation in susceptibility to estrogen-induced inflammation and pyometritis. In this article we report that following 10 weeks of treatment with the synthetic estrogen diethylstilbestrol (DES), Fisher 344 (F344) rats exhibit modest uterine inflammation and a 0% incidence of pyometritis. By contrast, under identical experimental conditions, Brown Norway (BN) rats exhibit significant inflammation and a 100% incidence of pyometritis. Similarly, we also observed profound uterine inflammation and a 100% incidence of pyometritis in a congenic rat strain in which a segment of RNO5 from the BN strain is carried on the F344 strain. These data suggest that a locus on RNO5 controls both the magnitude of DES-induced uterine inflammation and susceptibility to DES-induced pyometritis. This locus, designated Eutr2, resides within the same segment of RNO5 as the Eutr1 locus, which confers susceptibility to E2-induced pyometritis in an F2 population generated in a cross between the BN and August x Copenhagen 9935, Irish (ACI) strains.
