Uncontrolled release of Ca(2+) from the sarcoplasmic reticulum (SR) contributes to the reperfusion-induced cardiomyocyte injury, e.g. hypercontracture and necrosis. To find out the underlying cellular mechanisms of this phenomenon, we investigated whether the opening of mitochondrial permeability transition pores (MPTP), resulting in ATP depletion and(More)
Experimental and clinical studies demonstrated that postconditioning confers protection against myocardial ischemia/reperfusion injury. However the underlying cellular mechanisms responsible for the beneficial effect of postconditioning are still poorly understood. The aim of the present study was to examine the role of cytosolic and mitochondrial(More)
AIMS Since adenine nucleotide translocase 1 (ANT1) overexpression improved cardiac function in rats with activated renin-angiotensin system (RAS) and angiotensin II is known to enhance transforming growth factor β (TGFβ) signaling in cardiomyocytes, we assumed that ANT1 might modulate the classical TGFβ/SMAD pathway. We therefore investigated whether the(More)
Bronchopulmonary dysplasia is a chronic lung disease of preterm infants. It is caused by the disturbance of physiologic lung development mainly in the saccular stage with lifelong restrictions of pulmonary function and an increased risk of abnormal somatic and psychomotor development. The contributors to this disease's entity are multifactorial with pre-(More)
BACKGROUND Calcium (Ca2+) is a cofactor of multiple cellular processes. The mechanisms that lead to elevated cytosolic Ca2+ concentration are unclear. OBJECTIVE To illuminate how bloody cerebrospinal fluid (bCSF) from patients with intraventricular hemorrhage causes cell death of cultured human astrocytes. METHODS Cultured astrocytes were incubated with(More)
