Two subgroups of mitogen-activated protein kinases, c-jun NH2-terminal kinase (JNK) and extracellular signal-regulated kinase (ERK), are thought to be involved in cultured cardiac myocyte hypertrophy and gene expression. To examine the in vivo activation of these kinases, we measured cardiac JNK and ERK activities in conscious rats subjected to acute or(More)
Endothelin-1 (ET-1) is known to have potent contractile and proliferative effects on vascular smooth muscle cells and is known to induce myocardial cell hypertrophy. We studied the pathophysiological role of endogenous ET-1 in rats with monocrotaline-induced pulmonary hypertension. Four-week-old rats were given a single subcutaneous injection of 60 mg/kg(More)
Vascular smooth muscle cell (VSMC) proliferation is a critical event in the development and progression of vascular diseases, including atherosclerosis. We investigated whether the activation of adenosine monophosphate-activated protein kinase (AMPK) could suppress VSMC proliferation and inhibit cell cycle progression. Treatment of human aortic smooth(More)
BACKGROUND The effect of balloon injury on the arterial signal transduction pathway has not been examined. In vitro studies show that extracellular signal-regulated kinases (ERKs) and c-Jun NH2-terminal kinases (JNKs), belonging to the mitogen-activated protein kinase (MAPK) family, play a critical role in the activation of transcription factor activator(More)
The in vivo signal transduction pathway, responsible for hypertension-induced glomerular injury, remains to be clarified. In this study, the effect of angiotensin II (Ang II)-induced hypertension was examined on glomerular mitogen activated protein kinases (MAPK), including extracellular signal-regulated kinase (ERK) and c-jun NH2-terminal kinase (JNK), and(More)
In this paper, we propose a virtual agent system that introduces the current news on the Webs depending on the user's reactions to the understanding. We focused on the gesture of the user to estimate the user's state of understanding based on the head motion. The goal of the research is the user's under- standing of the news regardless of the knowledge(More)
