Accumulating evidence suggests that many brain diseases are associated with defects in neuronal migration, suggesting that this step of neurogenesis is critical for brain organization. However, the molecular mechanisms underlying neuronal migration remain largely unknown. Here, we identified the zinc-finger transcriptional repressor RP58 as a key regulator(More)
Dendritic trafficking and translation of brain-derived neurotrophic factor (BDNF) transcripts play a key role in mediating synaptic plasticity. Recently, we demonstrated that siRNA-mediated knockdown of translin, an RNA-binding protein, impairs KCl-induced dendritic trafficking of BDNF mRNA in cultured hippocampal neurons. We have now assessed whether(More)
The neocortex and the hippocampus comprise several specific layers containing distinct neurons that originate from progenitors at specific development times, under the control of an adequate cell-division patterning mechanism. Although many molecules are known to regulate this cell-division patterning process, its details are not well understood. Here, we(More)
The zinc finger transcription factor RP58 (also known as ZNF238) regulates neurogenesis of the mouse neocortex and cerebellum (Okado et al. 2009; Xiang et al. 2011; Baubet et al. 2012; Ohtaka-Maruyama et al. 2013), but its mechanism of action remains unclear. In this study, we report a cell-autonomous function for RP58 during the differentiation of(More)
RP58, a novel zinc finger protein containing a POZ domain, is a sequence-specific transcriptional repressor. To understand the role of this protein, we examined RP58 gene expression in the developing mouse brain by quantitative polymerase chain reaction (PCR) and in situ hybridization. RP58 mRNA expression was detected at embryonic day (E) 10 in the(More)
The recent emergence of severe acute respiratory syndrome (SARS) was caused by a novel coronavirus, SARS-CoV. It spread rapidly to many countries and developing a SARS vaccine is now urgently required. In order to study the immunogenicity of UV-inactivated purified SARS-CoV virion as a vaccine candidate, we subcutaneously immunized mice with UV-inactivated(More)
Normal human thymuses at various ages were immunohistologically examined in order to determine whether adult or aged thymus maintained the microenvironment for the T cell development and thymopoiesis was really ongoing. To analyze the thymic microenvironment, two monoclonal antibodies (MoAb) were employed. One is MoAb to IL-1 receptor (IL-1R) recognizing(More)
