Dr. Schwartz develops various oral cancer models to understand and quantify the earliest genetic and molecular events that change a normal cell to a cancer cell following exposure to virus or chemical carcinogen. First, in laboratory models Dr. Schwartz studies viral and chemical oral carcinogenesis using normal, transformed premalignant and malignant cells. Second, in animals such as, hamster, rat, and mouse, he validates laboratory findings and further assesses genetic and molecular progression as he changes a normal cell to a cancer cell. His approach also involves non-invasive screening of this process using oral cytology samples and RNA microarray. This method is unique because he harvests from the identical animal samples throughout the process of oral carcinogenesis. An identical approach is translated to clinical human populations to validate findings, to study early prevention or to monitor various therapies to improve the quality of life for the oral cancer patient.
