Definition

Prostate cancer genetic toxicology may have an endogenous or exogenous origin: (i) generation of 2- or 4-hydroxy metabolites of 17-estradiol (E2) via biotransforming enzymes including the phase I cytochrome P450 (CYP) isoform CYP1B1 ultimately giving rise to DNA damage or (ii) bio-activation by phase I metabolism and/or phase II metabolism of candidate causative agents of environmental and/or dietary origin to reactive metabolites that bind covalently to DNA bases.

There are two established risk factors for prostate cancer, the first being increasing age. However, the second is based on the epidemiological observation that there have been demographic regions of remarkably low prostate cancer incidence primarily in countries of the Far East (e.g., China, India, Japan) compared to levels observed in more Westernized areas (e.g., North/Western Europe, the USA, Australia). Populations that...
