Doxorubicin (DOX) is a classic anti-tumor chemotherapeutic used to treat a wide range of tumors. One major downfall of DOX treatment is it can induce fatal cardiotoxicity. Astragaloside IV (AS-IV) is one of the primary active ingredients that can be isolated from the traditional Chinese herbal medicine, Astragalus membranaceus. This study uses both in vitro and in vivo tools to investigate whether AS-IV alleviates DOX induced cardiomyopathy. We found that AS-IV supplementation alleviates body weight loss, myocardial injury, apoptosis of cardiomyocytes, cardiac fibrosis and cardiac dysfunction in DOX-treated mice. Also, DOX-induced cardiomyocyte injury and apoptosis were effectively improved by AS-IV treatment in vitro. NADPH oxidase (NOX) plays an important role in the progress of the oxidative signal transduction and DOX-induced cardiomyopathy. In this study, we found that AS-IV treatment relieves DOX-induced NOX2 and NOX4 expression and oxidative stress in cardiomyocytes. In conclusion, AS-IV, an antioxidant, attenuates DOX-induced cardiomyopathy through the suppression of NOX2 and NOX4.

The purpose of this study is to identify patients at risk for future heart failure using novel markers of early cardiac damage and determine if exercise training can improve these emerging...
An NADPH oxidase that is expressed by PHAGOCYTES where it transfers electrons across the plasma membrane from cytosolic NADPH to molecular oxygen on the exterior. It regulates proton (H+) flux into resting phagocytes to control intracellular pH. Mutations in the CYBB gene are associated with X-LINKED CHRONIC GRANULOMATOUS DISEASE.
A flavoprotein enzyme that catalyzes the univalent reduction of OXYGEN using NADPH as an electron donor to create SUPEROXIDE ANION. The enzyme is dependent on a variety of CYTOCHROMES. Defects in the production of superoxide ions by enzymes such as NADPH oxidase result in GRANULOMATOUS DISEASE, CHRONIC.
An NADPH oxidase that functions as a voltage-gated proton channel expressed by PHAGOCYTES, especially in the colon. It regulates intracellular pH, generates SUPEROXIDES upon activation by PHAGOCYTOSIS, and may play a role in INNATE IMMUNITY.
An NADPH oxidase that is strongly expressed in the kidney. It forms a complex with CYBA-P22PHOX and produces intracellular SUPEROXIDES that may regulate cellular signaling in APOPTOSIS; BONE RESORPTION; and NF-KAPPA B activation.
An NADPH oxidase that contains four EF HANDS and is expressed primarily by SPERMATOCYTES and LYMPHOCYTES, as well as by endothelial cells. It functions as a calcium-dependent proton channel to generate SUPEROXIDES that regulate cell growth, APOPTOSIS; and PHYSIOLOGIC ANGIOGENESIS.
Stress is caused by your perception of situations around you and then the reaction of your body to them. The automatic stress response to unexpected events is known as 'fight or flight'. Discovered by Walter Cannon in 1932, it is the release of h...

Alternative medicine are whole medical systems that did not fit with conventional medicine as they have completely different philosophies and ideas on the causes of disease, methods of diagnosis and approaches to treatment. Although often overlapping, co...
