Characteristics

Mammary tumours 84% at 7.7 months in DD, 4% at 20 months in DDfC57BL and 91% in DDfC3H at 6.7 months (Heston and Vlahakis, 1971). High serum haptoglobin level (2/11) (Peacock et al., 1967., 1967). High erythrocyte catalase (2/18) (Hoffman and Rechcigl, 1971). Host for transplantable androgen-dependent mouse mammary carcinoma SS-115, which only grows in intact males (Bruchovsky and Meakin, 1973). Develop keratinized nodules and squamous cell tumours when given urethan in the drinking water (Imai et al 1984). Low spontaneous locomotor activity (1/9) (Nikulina et al 1991).Carries an incomplete proviral genome of endogenous mammary tumour virus (MMTV) on the Y chromosome (c.f. 4/10) (Nishikawa et al 1991). Clonidene failed to produce an aggressive behavioural response (cf 3/9) (Nikulina and Klimek, 1993).
