| prevalence of murine mammary tumor virus antibody and antigens in normal and tumor-bearing feral mice. | approximately 20% of normal male and female feral mice (mus musculus) from areas with populations having either high [lake casitas (lc) and la puente] or low (bouquet canyon) spontaneous lymphoma incidence expressed murine mammary tumor virus (mumtv) gp52 in specific tissues. sera from a low percentage (6%) of mice from the same trapping areas contained precipitating antibody specific for mumtv. although moderate to high levels of mumtv gp52 were expressed in mammary tumor tissues of 3 of 7 lc m ... | 1978 | 210292 |
| prevalence and distribution of murine mammary tumor virus antigen detectable by immunocytochemistry in spontaneous breast tumors of wild mice. | mouse mammary tumor virus (mumtv) antigens were detected by immunoperoxidase cytochemistry in spontaneous breast tumors of wild mice from two widely separated areas of southern california. eleven of 25 (44%) tumors from lake casitas (lc) mice and 4 of 5 tumors from bouquet canyon mice were positive. included among the tumors lacking detectable mumtv antigen were well-differentiated type a and type b carcinomas as well as tumors with an atypical pattern. in the antigen-positive tumors the distrib ... | 1980 | 6245303 |
| genetic control of retroviral disease in aging wild mice. | different populations of wild mice (mus musculus domesticus) in los angeles and ventura counties were observed over their lifespan in captivity for expression of infectious murine leukemia virus (mulv) and murine mammary tumor virus (mmtv) and for the occurrence of cancer and other diseases. in most populations of feral mice these indigenous retroviruses were infrequently expressed and cancer seldom occurred until later in life (> 2 years old). mmtv was found in the milk of about 50% of wild mic ... | 1993 | 8125269 |
