Female BALB\/c (H-2d) mice carrying the activated HER-2\/ neu oncogene show no morphological abnormalities of the mammary gland until 3 wk of age. They then progress through atypical hyperplasia to in situ lobular carcinoma and at 33 wk of age all 10 mammary glands display invasive carcinomas. Adult FVB mice (H-2q) carrying the HER-2\/neu protooncogene develop mammary carcinomas with a longer latency (38-49 wk) and a lower multiplicity (mean of 2.6 tumors\/mice). Treatment with IL-12 (5 daily intraperitoneal injections, 1 wk on, 3 wk off; the first course with 50 ng IL-12\/day, the second with 100 ng IL-12\/day) begun at 2 wk of age in BALB\/c mice and at 21 wk of age in FVB mice markedly delayed tumor onset and reduced tumor multiplicity. Analogous results were obtained in immunocompetent and permanently CD8+ T lymphocyte\u2013depleted mice. In both transgenic lines, tumor inhibition was associated with mammary infiltration of reactive cells, production of cytokines and inducible nitric oxide synthase, and reduction in microvessel number, in combination with a high degree of hemorrhagic necrosis.<\/jats:p>","DOI":"10.1084\/jem.188.3.589","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T16:49:30Z","timestamp":1027702170000},"page":"589-596","update-policy":"https:\/\/doi.org\/10.1084\/jem.crossmarkpolicy","source":"Crossref","is-referenced-by-count":233,"title":["Interleukin 12\u2013mediated Prevention of Spontaneous Mammary Adenocarcinomas in Two Lines of Her-2\/<i>neu<\/i> Transgenic Mice"],"prefix":"10.1084","volume":"188","author":[{"given":"Katia","family":"Boggio","sequence":"first","affiliation":[{"name":"From the *Department of Clinical and Biological Sciences, University of Turin, 10043 Orbassano, Italy;
