Levels of biological markers of nitric oxide in serum of patients with squamous cell carcinoma of the oral cavity
An evaluation of the levels of nitric oxide (NO) and two markers of NO activity in the blood of people with oral cancer highlights possible roles for these compounds in cancer progression. Wioletta Ratajczak-Wrona and colleagues at the Medical University of Bialystok, Poland, measured the levels of NO and the markers — malonyldialdehyde and nitrotyrosine — in 24 people with squamous cell carcinoma of the oral cavity, before and after surgical removal of a tumor. Concentrations of NO were greatest in individuals with advanced disease, consistent with the body mounting an immune attack. Following treatment, these concentrations dropped, suggesting a role for tumor cells in the secretion of this molecule. Malonyldialdehyde and nitrotyrosine levels followed different patterns, indicating that their production may not depend entirely on NO concentration. These compounds might also affect tumor development in different ways.
