Includes bibliographical references (p. 125-140). / Tobacco smoking is a major risk factor in the development of oesophageal squamous cell carcinoma (OSCC). Benzo[a]pyrene (BaP) is a tobacco smoke procarcinogen that is metabolically activated into the carcinogenic benzo[a]pyrene diol-epoxide (BPDE) by the CYP1 family of cytochrome P450 enzymes. BaP is a ligand for the aryl hydrocarbon receptor (AhR) which activates CYP1 gene transcription. Polymorphisms in these genes affect enzyme activity and therefore BaP bioactivation.
