Abstract | Background: High levels of testosterone (Testo) are associated with cardiovascular risk by increasing reactive oxygen species (ROS) formation. NADPH oxidases (NOX) are the major source of ROS in the vasculature in cardiovascular diseases. NOX4 is a unique isotype, which produces hydrogen peroxide (H Methods: Human Mesenteric Vascular Endothelial Cells (HMEC) and Human Umbilical Vein Endothelial Cells (HUVEC) were treated with Testo (10 Results: Testo increased mRNA and protein levels of NOX4 in HMEC and HUVEC. Testo increased superoxide anion (O Conclusion: These data indicate that supraphysiological levels of Testo increase the endothelial expression and activity of NOX4 to counterbalance the deleterious effects caused by Testo in endothelial function. |
