MicroRNAs (miRNAs) are thought to modulate a variety of cellular events. Several studies have revealed the functions of miR-223 in granulopoiesis. Here we analysed miR-223 expression in various human tissues, blood and leukaemia cells, and focused on its role in K562 erythroid and megakaryocytic differentiation. MiR-223 was detected not only in granulocytes(More)
Hypoxia-inducible factor promotes erythropoiesis through coordinated cell type-specific hypoxia responses. GATA1 is essential to normal erythropoiesis and plays a crucial role in erythroid differentiation. In this study, we show that hypoxia-induced GATA1 expression is mediated by HIF1 in erythroid cells. Under hypoxic conditions, significantly increased(More)
To better understand the transcriptional program that accompanies orderly lineage-specific hematopoietic differentiation, we analyzed expression changes during the lineage-specific differentiation of human hematopoietic stem cells (HSC; CD34+/CD38-/CD33-); HSC and multipotent myeloid progenitors (MMP; CD34+/CD38-/CD33+) were isolated from the bone marrow of(More)
BACKGROUND Tau protein is implicated in the pathogenesis of neurodegenerative disorders such as tauopathies including Alzheimer disease, and Tau fibrillization is thought to be related to neuronal toxicity. Physiological inhibitors of Tau fibrillization hold promise for developing new strategies for treatment of Alzheimer disease. Because protein disulfide(More)
BACKGROUND The misfolding of amyloidogenic proteins including human Tau protein, human prion protein, and human α-synuclein is involved in neurodegenerative diseases such as Alzheimer disease, prion disease, and Parkinson disease. Although a lot of research on such amyloidogenic proteins has been done, we do not know the determinants that drive these(More)
Pentylenetetrazole (PTZ) is a widely-used convulsant used in studies of epilepsy; its subcutaneous injection generates an animal model with stable seizures. Here, we compared the ability of PTZ via the intravenous and subcutaneous routes to evoke progressive epileptiform activity in the hippocampal CA1 neurons of anesthetized rats. The involvement of the(More)
FOXL2 is a member of the forkhead box family, a transcription factor essential for the early regulation of ovarian development that is expressed in a sexually dimorphic manner in vertebrates. However, data on this gene in invertebrates are rare. In this study, we cloned a full-length cDNA sequence of foxl2 from the scallop Chlamys farreri, an important(More)
In the title compound, C(18)H(15)N(3)O(3)·0.5CH(2)Cl(2), the fused ring benzofuro[2,3-d]pyrimidine system is essentially planar [maximum deviation 0.029 (1) Å]. The planes of the pyrimidinone and phenyl rings are nearly perpendicular [dihedral angle = 87.50 (14)°]. The packing of the mol-ecules in the crystal structure is governed mainly by inter-molecular(More)
The purpose of this study was to describe microsurgical anatomy of the dorsal root entry zone (DREZ) and provide an anatomic basis for the approach of DREZ lesion in treating radiculopathy of brachial plexus avulsion injuries. We studied 100 dorsal cervical roots and DREZ/posterior horn complexes in 20 adult cadavers. At each root level the following data(More)
