## Abstract The heterocyclic amines (HCAs) are a family of mutagenic/carcinogenic compounds found in cooked meats. Several HCAs are mammary gland carcinogens in rats. Of these compounds, 2βaminoβ1βmethylβ6βphenylimidazo[4,5β__b__]pyridine (PhIP) is the major one present in the human diet. This repo

2-Amino-1-methyl-6-phenylimidazo(4,5-b)pyridine (PhIP), a compound found in cooked meat, is a mammary gland carcinogen in female Sprague-Dawley rats. PhIP-induced rat mammary gland carcinomas were examined for mutations in several genes (exons) known to regulate cell growth and apoptosis, including
## Abstract Reduced expression of BRCA1 protein, caused by the hypermethylation of its gene promoter and by other mechanisms, is observed in most sporadic human breast cancers, whereas its somatic mutations are rare. In the present study, we demonstrate that immunoreactivity of __Brca1__ was reduce
## Microsatellite instability (MI) and loss of heterozygosity (LOH) were examined in mammary tumors induced in Sprague-Dawley x F344 F1 female rats by 2-amino-l-methyl-6-phenylimidazo[4,5-blpyridine (PhlP). Examination of 62 microsatellite loci revealed M I in nine of 15 (60%) PhlP-induced mammary
## Abstract Epithelial cells are the primary site of carcinogenesis in most tissues, including the mammary gland. As an alternative to the study of mutation induction in whole tissues in vivo, we have established Big Blueβ’ transgenic rat cell lines from the mammary epithelium (BBR/ME) and the mamma
Damage to the human adenomatous polyposis coli (APC) gene is responsible for not only familial adenomatous polyposis but also many sporadic cancers of the entire digestive tract. Using homologous recombination in embryonic stem cells, we recently constructed gene knockout mice with a truncation muta
