Oral squamous cell carcinoma (OSCC) is the most common subsite of head and neck cancer, with a 5-year survival rate of only 50%. There is a pressing need for animal models that recapitulate the human disease to understand the factors driving OSCC carcinogenesis. Many laboratories have used the chemical carcinogen 4-nitroquinoline-1-oxide (4NQO) to investigate OSCC formation.
