Cytokines, nitric oxide (NO) and reactive oxygen species (ROS) are well known for their pathogenic effects in development of cardiovascular diseases. Interleukin-1beta (IL-1beta) is known to induce NO generation, however it is not well established if IL-1beta or NO regulate production of ROS, such as superoxide anion. Therefore, the main objective of this study was to evaluate the effect of IL-1beta or NO on enzyme activity of NADPH oxidase (NOX), a superoxide-generating system recently documented to participate in a variety of vascular functions.
