Project Abstract Tobacco use remains a high risk factor for oral squamous cell carcinoma (OSCC) resulting from exposure to potent tobacco carcinogens including polycyclic aromatic hydrocarbons (PAHs) such as dibenzo[a,l]pyrene (DB[a,l]P), benzo[a]pyrene (B[a]P) and tobacco-specific nitrosamines (TSNA) such as N’-nitrosonornicotine (NNN). To assess effects of these carcinogens on oral mucosa, we developed a novel OSCC mouse model using DB[a,l]P and its fjord region diol epoxide (DB[a,l]PDE). Importantly, we showed that dietary intervention with freeze-dried black raspberries (BRB) powder inhibited carcinogen-induced DNA damage, mutagenesis and carcinogenesis in the mouse oral cavity. We have…
