astragaloside iv/hypoxia

BACKGROUND Astragaloside IV (As-IV) exerts beneficial effects on hypoxia/reoxygenation (H/R)-induced cardiomyocyte injury, possibly through normalization of sarcoplasmic reticulum Ca(2+) ATPase (SERCA2a) function. The exact mechanisms remain unknown. This study was designed to investigate the role

Astragaloside IV (ASI), a traditional Chinese medicine, is a main active ingredient of Astragalus membranaceus. Many clinical studies have found that ASI protects cardiomyocytes in cardiovascular diseases, but the underlying mechanisms remain obscure. The aim of this study was to investigate the

BACKGROUND Astragalus membranaceus has been clinically used in cerebral ischemia treatment in China and its main component, Astragaloside IV (Ast IV) shows anti-hypoxia activity, but the underlying mechanism has not been clearly clarified. This study was aimed to investigate the effects of Ast IV on

Astragaloside IV (AS/IV) is one of the extracted components from the traditional Chinese medicine Astragalus which has been demonstrated to have potential capacity for anti-inflammation activity and for treating cardiovascular disease. Our purpose was to determine the function and underlying

Astragaloside IV is the major active constituent of Astragalus membranaceus, which has been widely used for the treatment of cardiovascular diseases in China. The aim of this study was to determine the angiogenic effect of astragaloside IV and its underlying mechanism. We used the

BACKGROUND Herbal medicines including Tanshinone IIA (TanIIA) and Astragaloside IV (AsIV) are widely used in Asia as therapeutic agents for cardiovascular diseases, due to their complementary roles and shared properties based on the theory of traditional Chinese medicine and pharmacological

OBJECTIVE Astragaloside IV (AS-IV), a traditional Chinese medicine isolated from Astragalus membranaceus, has been shown to exert cardioprotective effect previously. This study aimed to reveal the effects of AS-IV on hypoxia-injured cardiomyocyte. METHODS H9c2 cells were treated with various doses

Although astragaloside IV, a saponin isolated from Astragalus membranaceus, has been shown to protect the myocardium against ischemia/reperfusion injury, its effect on the status of sarcoplasmic reticulum (SR) Ca2+ transport in the injured myocardium remains largely unknown. In this study, we

Astragaloside IV (AS-IV) is one of the main pharmacologically active compounds found in Astragalus membranaceus. AS-IV has protective effects against ischemia-reperfusion injury (IRI), but its mechanism of action has not yet been determined. This study aims to investigate the effect of AS-IV on IRI

Obstructive sleep apnea syndrome (OSAS) is an important consequence of chronic intermittent hypoxia (CIH). Astragaloside IV (AS-IV) exerts multiple protective effects in diverse diseases. However, whether AS-IV can attenuate CIH-induced myocardial injury is unclear. In this study, rats exposed to

1. Astragaloside IV (AST-IV) is purified from a natural plant product. Previous studies have shown that AST-IV has anti-oxidant activity. In the present study, we investigated the effect and mechanism of action AST-IV on rat cardiomyocytes subjected to hypoxic conditions (up to 12 h). 2.

Our previous studies showed that Astragaloside IV derivative (LS-102) exhibited potent protective function against ischemia reperfusion (I/R) injury, but little is known about the mechanisms. Mitochondrial fission regulated by dynamin-related protein1 (Drp1) is a newly recognized determinant of
