Classically activated macrophages (M1) or alternatively activated macrophages (M2) have different functions during helminth infections including Trichinella spiralis (T. spiralis). The excretory/secretory antigens (ESA) of T. spiralis can inhibit macrophage pro-inflammatory cytokines production. However, the specific molecules of ESA that regulate(More)
The hypoxia-inducible factor 1α (HIF-1α) regulates transcriptional genes involved in cell proliferation, survival, and differentiation. Under normoxia, HIF-1α has a short half-life (t ½ ≈ 5 min) and low transcriptional activity. An HIF-1α mutant, produced by substitution of alanine (Ala) for proline (Pro) at position 564 and asparagine (Asp) at position(More)
Identification of endogenous angiogenesis inhibitors has led to development of an increasingly attractive strategy for cancer therapy and other angiogenesis-driven diseases. Vascular endothelial growth inhibitor (VEGI), a potent and relatively nontoxic endogenous angiogenesis inhibitor, has been intensively studied, and this work shed new light on(More)
INTRODUCTION The function of the repolarization reserve in the prevention of ventricular arrhythmias during cardiac ischemia/reperfusion and the impact of ischemia on slowly activated delayed rectifier potassium current (I(Ks)) channel subunit expression are not well understood. METHODS AND RESULTS The responses of monophasic action potential duration(More)
Kv1.5 potassium channel represents a promising target for atrial fibrillation (AF) therapy. During AF, the renin-angiotensin system is markedly activated. Recent evidence indicates that angiotensin II (Ang II) can upregulate Kv1.5 channel, but the mechanism remains unknown. In this study, we report that Ang II-mediated transforming growth factor-beta1(More)
Our previous study demonstrated that angiotensin II (Ang II) upregulates the expression of Kv1.5, a promising target for atrial fibrillation (AF) therapy, by activating ROS-dependent P-Smad2/3 and P-ERK 1/2. A recent study showed that hydrogen sulfide (H2S) may modulate the effects of angiotensin II (Ang II) by inhibiting the NADPH oxidase 4 (Nox4)-ROS(More)
Bone marrow derived stromal cells (MSCs) can prevent the apoptosis of ischemic cardiomyocytes (CMCs). This anti-apoptosis activity may be related to an activation of the HIF-1alpha signal pathway in MSCs. Therefore, we investigated protective effects of an adenovirus (Ad)-mediated active form of HIF-1alpha (HIF-1alpha-Ala564-Ala803) modified MSCs on CMCs(More)
Adenovirus-mediated expression of hypoxia-inducible factor 1α double mutant (pAd-HIF-1α-Ala564-Ala803) can be effectively transfected into bone marrow stem cells (MSCs) in the MSCs and cardiomyocytes co-culture system at normoxia to regulate the expression of downstream target genes of hypoxia-inducible factor 1α (HIF-1α), which in turn can promote MSC(More)
High glucose‑induced endothelial cell apoptosis is considered to be the initiator of diabetes‑associated vascular complications. Experiments in vivo and in vitro have demonstrated that high glucose levels contribute to the apoptosis of endothelial cells by mediating cellular dysfunction and metabolic disorder via the production of various cytokines. As the(More)
INTRODUCTION Whole lung lavage is the most effective method to treat pulmonary alveolar proteinosis (PAP), and most potential complications occur often during the lavage process, but few happen after lavage. Theoretically, pulmonary edema would be more common after whole lung lavage. However, no such case was reported in the literature. CASE DESCRIPTION A(More)
