Mechanism of Aromatic Hydrocarbon Induced Mammary Tumorigenesis
Abstract
Recent evidence suggests that the rise in breast cancer rates reflects increased exposure to and bioaccumulation of environmental pollutants, such as 7,12-dimethylbenz(a)anthracene (DMBA). Female Sprague-Dawley rats treated with DMBA develop mammary (breast) tumors by about 15 weeks. Here we proposed to elucidate the roles of the aromatic hydrocarbon (Ah) and estrogen receptors and the c-myc oncogene. The hypothesis investigated was that administration of DMBA would lead to AhR-mediated induction of P-45O enzymes.
