CXCR4 is the receptor of stromal cell-derived factor (SDF-1) and is expressed in many types of cancer cells. It also plays an important role in metastasis of malignant disease. In this study, we detected the expression of CXCR4 in 81 patients with myelodysplastic syndrome (MDS) by flow cytometry. We categorized MDS patients into the high-expression group(More)
Pseudolaric acid B (PAB), a natural diterpene acid present in the traditional Chinese medicinal herb Tu-Jin-Pi, exerted anticancer effects on various cancer cells. However, the effect of PAB on DU145 cells, an in vitro model of hormone-refractory prostate cancer (HRPC), has not been reported previously. In the study, PAB significantly suppressed(More)
Hypoxia-inducible factor 1α (HIF-1α) is a master regulator of cellular adaptation to hypoxia and has been proposed as a potent therapeutic target for cerebral ischemia. However, research on the expression and effects of HIF-1α in subarachnoid hemorrhage (SAH) is limited. The aim of the present study was to investigate the expression of HIF-1α in the(More)
Matrine, a alkaloid of the root of Sophora flavescens, has multiple protective effects on the cardiovascular system including cardiac arrhythmias. However, the molecular and ionic mechanisms of matrine have not been well investigated. Our study aimed at to shed a light on the issue to investigate the antiarrhythmic effects of matrine by using ouabain to(More)
Acute myeloid leukemia (AML) is a malignant and aggressive disease not sensitive to chemotherapy. The dynamic interaction between AML cells and bone marrow (BM) microenvironment plays a critical role in response of this disease to chemotherapy. It is reported that mesenchymal stromal cells (MSC) are essential component of bone marrow microenvironment which(More)
This study assessed the preparedness of school health personnel to develop and deliver HIV/AIDS prevention education programmes for young people in China. A survey of 653 personnel working in secondary schools in 14 cities was conducted. More than 90% had basic knowledge of ways in which HIV can be transmitted, but knowledge of ways in which the virus is(More)
NYGGF4 is a recently discovered gene that is involved in obesity-associated insulin resistance. In this study, an Hi-Line Brown chicken homolog of the NYGGF4 gene was cloned, sequenced, and characterized. The NYGGF4 full-length coding sequence (CDS) consists of 654 bp and encodes 217 amino acids with a molecular mass of 25,00 kD. The phosphotyrosine binding(More)
Cardiac fibrosis is a major cause of heart failure. MicroRNAs (miRs) are important epigenetic regulators of cardiac function and cardiovascular diseases, including cardiac fibrosis. This study aimed to explore the role of miR-503 and its mechanisms in regulating cardiac fibrosis. miR-503 was found up-regulated in the mouse LV tissues subjected to transverse(More)
Enterovirus 71 (EV71) and Coxsackievirus A16 (CVA16) have caused severe epidemics of hand, foot and mouth disease (HFMD) in the Asia Pacific in recent years, particularly in infants and young children. This disease has become a serious public health problem, as no vaccines or antiviral drugs have been approved for EV71 and CA16 infections. In this study, we(More)
A disintegrin and metalloprotease 17 (ADAM17) is a transmembrane protein that can cleave membrane anchored proteins to release soluble factors and regulate important biological phenomena in cancers. In the present study, we evaluated the effects of ADAM17 on the proliferation and on the cell cycle distribution of human prostate cancer cells. Experiments(More)
