Prostaglandin plays an important role in the pathogenesis of hepatic encephalopathy. This study investigated the therapeutic effects of selective cyclooxygenase (COX) inhibitor on hepatic encephalopathy in thioacetamide-induced fulminant hepatic failure (FHF) rats. The selective COX-1 inhibitor (SC-560), COX-2 inhibitor (NS-398) or distilled water (control)(More)
BACKGROUND Aliskiren is a direct renin inhibitor used in the treatment for arterial hypertension. It can also augment nitric oxide (NO) production, which plays a crucial role in the pathogenesis of portal hypertension and modulation of porto-systemic collaterals. This study investigated the effects of aliskiren on portal pressure and porto-systemic(More)
UNLABELLED AMP-activated protein kinase (AMPK) is a metabolic master switch maintaining the energy homeostasis in cells and thought to modulate cellular response to stresses. Adenine as well as a pharmacological AMPK activator, 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR), induced the phosphorylation of AMPK and acetyl-CoA carboxylase in NIH/3T3(More)
The AMP-activated protein kinase (AMPK) signaling system plays a key role in cellular stress by repressing the inflammatory responses induced by the nuclear factor-kappa B (NF-κB) system. Previous studies suggest that the anti-inflammatory role of AMPK involves activation by adenine, but the mechanism that allows adenine to produce these effects has not yet(More)
