The segregation of neural and epidermal progenitors in Drosophila requires the activity of transcription factors encoded by the proneural genes and the genes of the E(SPL)-C. Persistent expression of two genes of the E(SPL)-C suppresses neural development. Embryos exhibit conspicuous central neural hypoplasia and lack sensory organs; imaginal sensory organs(More)
The first step in the development of the Drosophila optic medullar primordia is the expansion of symmetrically dividing neuroepithelial cells (NEs); this step is then followed by the appearance of asymmetrically dividing neuroblasts (NBs). However, the mechanisms responsible for the change from NEs to NBs remain unclear. Here, we performed detailed analyses(More)
Notch1 plays various important roles including the maintenance of the stem cell state as well as the promotion of glial fates in mammalian CNS development. However, because of the very low amount of the activated form of Notch1 present in vivo, its precise activation pattern has remained unknown. In this study, we mapped the active state of this signaling(More)
Notch signaling plays various key roles in cell fate determination during CNS development in a context-dependent fashion. However, its precise physiological role and the localization of its target cells remain unclear. To address this issue, we developed a new reporter system for assessing the RBP-J-mediated activation of Notch signaling target genes in(More)
This paper describes a system called ComicDiary that automatically creates a personal diary in a comics style. ComicDiary is built as a subsystem of our ongoing project (C-MAP) to develop a personal guidance system for exhibition touring at museums, trade shows, academic conferences, cities, and so on. The aim of the C-MAP system is to provide users with(More)
Inflammatory cytokines cause tissue dysfunction. We previously reported that retinal inflammation down-regulates rhodopsin expression and impairs visual function by an unknown mechanism. Here, we demonstrate that rhodopsin levels were preserved by suppressor of cytokine signaling 3 (SOCS3), a negative feedback regulator of STAT3 activation. SOCS3 was(More)
Ciliary neurotrophic factor (CNTF) has been known to inhibit the differentiation of presumptive rod photoreceptor cells; however, the underlying mechanisms have remained to be elucidated. We demonstrated that STAT3 activation, but not SHP2 activation, is responsible for the CNTF/gp130 signaling that inhibits expression of Rhodopsin and its upstream(More)
Starting from the days of the Musical Telegraph, the first electronic instrument, the majority of synthesizers today are still equipped with keyboards, often using the traditional layout of acoustic pianos. The question that many researchers attempt to answer is that of improvement. In this paper we present an Augmented Groove, a novel musical instrument(More)
Mammalian Numb (mNumb) has multiple functions and plays important roles in the regulation of neural development, including maintenance of neural progenitor cells and promotion of neuronal differentiation in the central nervous system (CNS). However, the molecular bases underlying the distinct functions of Numb have not yet been elucidated. mNumb, which has(More)
Mutations in the Autism susceptibility candidate 2 gene (AUTS2), whose protein is believed to act in neuronal cell nuclei, have been associated with multiple psychiatric illnesses, including autism spectrum disorders, intellectual disability, and schizophrenia. Here we show that cytoplasmic AUTS2 is involved in the regulation of the cytoskeleton and neural(More)
