A pilot study has been designed to determine (primary objective) if three brief interventions with three oral BSE regimens will alter mRNA biomarkers of Nrf2 pathway signaling, including NQO1, GSTs and AKRs, in the oral mucosa of healthy subjects. Quantitative distribution data and preliminary effect size for specific Nrf2 targets, as measured in serial buccal cell scrapings, will be determined during the course of 3-day exposures to three BSE regimens. These data will inform the design of a randomized, phase II chemoprevention trial in patients with HPV-negative HNSCC. Ten healthy volunteers will be recruited for this pilot study, Age ≥ 18 years, both male and female: 1) The non-cancer population presenting to the University of Pittsburgh Eye and Ear Institute or the Hillman Cancer Center. This may include patients with benign disease or their friends/family members, or friends/family members of patients with cancer; 2) Professionals, staff, or students at the University of Pittsburgh.
