Dr. Norton’s research investigates the mechanisms by which smooth muscle and endothelial cells can be protected from conditions of acute oxidative stress such as stroke. Remarkably, advanced age and western style diet (conditions of chronic oxidative stress) increase the resilience of cells exposed to acute oxidative stress. Furthermore, arteries from females are less susceptible to acute oxidative stress than males. By understanding how to target these protective mechanisms, new strategies can be developed for maintaining blood flow control following ischemic injury.
Dr. Norton’s secondary research interest centers on understanding mechanisms of pulmonary hypertension. Pulmonary fibrosis has a strong correlation between the development of pulmonary hypertension and patient mortality. Therefore, this research seeks to identify signaling mechanisms unique to pulmonary fibrosis-induced pulmonary hypertension.
