Vascular endothelial growth factor-A (VEGF-A) is one of the major angiogenic factors, and its actions are primarily mediated through its two membrane receptors, VEGFR-1 and VEGFR-2. A soluble form of VEGFR-1 (sVEGFR-1) sequesters the free form of VEGF-A, and acts as a potent anti-angiogenic factor. While sVEGFR-1 is synthesized as a splice variant of(More)
In severely hypoxic condition, HIF-1α-mediated induction of Pdk1 was found to regulate glucose oxidation by preventing the entry of pyruvate into the tricarboxylic cycle. Monocyte-derived macrophages, however, encounter a gradual decrease in oxygen availability during its migration process in inflammatory areas. Here we show that HIF-1α-PDK1-mediated(More)
A 49-year-old man presenting with ST-elevated myocardial infarction was brought to our emergency department with AL amyloidosis. Baseline coronary angiography showed no significant stenosis of the epicardial coronary arteries, however, coronary artery angiography in response to acetylcholine and coronary flow reserve in response to papaverine were abnormal,(More)
Mitral and aortic valve regurgitation is commonly found in osteogenesis imperfecta (OI) patients, however, little is known about the myocardial involvement in this disorder. An 82-year-old man with OI developed heart failure and was admitted to our hospital. Echocardiogram revealed severe mitral regurgitation without left ventricular (LV) dilatation, but(More)
Left ventricular outflow tract obstruction (LVOTO) is commonly observed in patients with hypertrophic cardiomyopathy (HCM) or left ventricular hypertrophy (LVH). While some patients develop LVOTO at rest, it can also be provoked by physical exertion, and hence termed latent LVOTO (L-LVOTO). Recent reports demonstrated that L-LVOTO develops not only in LVH(More)
