Reactive Oxygen and Nitrogen Species in the Development of Pulmonary Hypertension
Pulmonary arterial hypertension (PAH) is a progressive disease of the lung vasculature that involves the loss of endothelial function together with inappropriate smooth muscle cell growth, inflammation, and fibrosis. These changes underlie a progressive remodeling of blood vessels that alters flow and increases pulmonary blood pressure. Elevated pressures in the pulmonary artery imparts a chron...
متن کاملReactive oxygen species as therapeutic targets in pulmonary hypertension.
Pulmonary hypertension (PH) is characterized by a progressive elevation of pulmonary arterial pressure due to alterations of both pulmonary vascular structure and function. This disease is rare but life-threatening, leading to the development of right heart failure. Current PH treatments, designed to target altered pulmonary vascular reactivity, include vasodilating prostanoids, phosphodiestera...
متن کاملBioimaging Probes for Reactive Oxygen Species and Reactive Nitrogen Species
Reactive oxygen species (ROS) play key roles in many pathogenic processes, including carcinogenesis, inflammation, ischemia-reperfusion injury and signal transduction. Also, reactive nitrogen species (RNS) cause various biological events such as neurodegenerative disorders. Sensitive and specific detection methods for ROS and RNS in biological samples should be useful for elucidation of biologi...
متن کاملBiochemistry of Reactive Oxygen and Nitrogen Species
Reactive species or free radicals include reactive oxygen and nitrogen species that are called reactive oxygen nitrogen species. Reactive oxygen species are formed as a natural by-product of the normal metabolism of oxygen and have significant roles in cell signaling and homeostasis. The reactive oxygen species are generated as a byproduct of biochemical reactions, in mitochondria, peroxisomes,...
متن کاملReactive oxygen species, NADPH oxidases, and hypertension.
Reactive oxygen species (ROS) produced in the neuronal, renal, and vascular systems not only influence cardiovascular physiology but are also strongly implicated in pathological signaling leading to hypertension. Different sources of ROS have been identified, ranging from xanthinexanthine oxidase and mitochondria to NADPH oxidase (Nox) enzymes. Of 7 Nox family members, Nox1, Nox2, and Nox4 (and...
