Strain Synonyms: MDC-04-48; ACI
Phenotype
Will grow transplantable Morris hepatomas 3924A which can be used as a model for the treatment of liver cancer. Median survival 113 weeks in males, 108 weeks in females. Spontaneous tumours 46% testes,16% adrenal, 5% pituitary, 6% skin and ear duct and fewer of other types in males; 21%pituitary, 13% uterus, 11% mammary gland, 6% adrenal and fewer of other types in females. Other conditions include 28% of males and 20% of females with absent, hypoplastic or cystic kidneys on one side sometimes associated with an absent or defective uterine horn or atrophictestes on the same side. These abnormalities have a polygenic mode of inheritance. Spontaneous adenocarcinomas of ventral prostate seen in 7/41 untreated males at 34-37 months. This is substantially increased by a high fat diet. High survival to 2 years of age at 74% (rank 2/5) in males and 70% (rank 1/5) in females. However, a high incidence of relatively mild chronic renal disease and a high incidence of hydronephrosis and the congenital renal agenesis may make the strain unsuitable for long-term toxicological studies. Four spontaneous kidney and five bladder tumours found among a cohort of 300 rats maintained for 30 months. Urolithiasis seen in 2/55 rats at an average age of 144 days. A diet deficient in choline and methionine has been used to develop a rat model of fatty liver transplantation.
