Spontaneous lesions in aging FVB/N mice . … , which facilitate microinjection of DNA. Little is known, however, about the survivability and spontaneous disease of nontransgenic FVB/N mice . Therefore, the purpose of this study was to determine survival to 24 mo of age and the incidence of neoplastic and nonneoplastic disease at 14 and 24 mo of …

The FVB/N mouse strain is extensively used in the development of animal models for breast cancer research. Recently it has been reported that the aging FVB/N mice develop spontaneous mammary lesions and tumors accompanied with abnormalities in the pituitary glands. These observations have a great impact on the mouse models of human breast cancer.
9/30/2015 · FVB/N wild type and transgenic HER-2/neu FVB/N female mice breed at N . N . Petrov Research Institute of Oncology were under observation until natural death without any special treatment. Age-related dynamics of body weight, food consumption and parameters of carbohydrate and lipid metabolism, level of nitric oxide, malonic dialdehyde, catalase, Cu, Zn-superoxide dismutase, vascular.
The TG.AC mouse has an FVB/N genetic background and commonly develops several internal tumors that can arise spontaneously by 7 months of age (Table III).Because a carcinogenic response in genetically modified models can be manifested as an increase in the incidence of spontaneous tumors, the relatively high background incidence in TG.AC mice could complicate the interpretation of.
Since genetically engineered FVB mice are frequently used to study mammary tumor biology, we have examined a cohort of 64 aging wild-type FVB/N females to establish the prevalence and the nature of spontaneous mammary and pituitary tumors. Tissues from mammary and pituitary glands were studied by histopathology and immunohistochemistry.
However, the behavioral features of FVB/N mice and numerous studies using excitotoxins to induce seizure activity indicate that this strain experiences multiple sublethal seizures. To assess whether FVB/N mice develop histologically detectable lesions , we evaluated the brains of 86 aged (154-847 d) FVB/N mice without a history of seizures.
Approximately 60% of FVB Mice regardless of sex survive to two years of age. By this point, approximately 60% of surviving mice show tumors/ lesions . Some sudden deaths are observed in younger animals, but most die at 15 months or older. Two years is a common life expectancy in wild-type house mice .
