    Drosophila medulla neuroblast termination via apoptosis, differentiation, and gliogenic switch is scheduled by the depletion of the neuroepithelial stem cell pool

    Phuong-Khanh Nguyen, Louise Y Cheng
    The termination of medulla neuroblasts is specified by the depletion of the neuroepithelium and mediated by apoptosis, differentiation, and gliogenic switch.

    Neuroblast-specific open chromatin allows the temporal transcription factor, Hunchback, to bind neuroblast-specific loci

    Sonia Q Sen, Sachin Chanchani ... Chris Q Doe
    Spatial factors generate neuroblast-specific open chromatin, thereby biasing the subsequent binding of transcription factors to produce neuroblast-specific neurons.

    Differences in size and number of embryonic type II neuroblast lineages correlate with divergent timing of central complex development between beetle and fly

    Simon Rethemeier, Sonja Fritzsche ... Vera S Hunnekuhl
    Genetic labeling and molecular analyses characterize the dynamics of embryonic central complex-forming type II neuroblast lineages in Tribolium castaneum.

    Single nuclei RNA-sequencing of adult brain neurons derived from type 2 neuroblasts reveals transcriptional complexity in the insect central complex

    Derek G Epiney, Gonzalo Morales Chaya ... Chris Q Doe
    The central complex of the adult Drosophila brain, required for sensorimotor integration, is transcriptionally complex as detected by single-cell transcriptome analysis.

    Delta-dependent Notch activation closes the early neuroblast temporal program to promote lineage progression and neurogenesis termination in Drosophila

    Chhavi Sood, Md Ausrafuggaman Nahid ... Sarah E Siegrist
    Notch signaling regulates the neuroblast intrinsic temporal program to determine when neuroblasts terminate their cell divisions during development.

    Vibrator and PI4KIIIα govern neuroblast polarity by anchoring non-muscle myosin II

    Chwee Tat Koe, Ye Sing Tan ... Hongyan Wang
    Vibrator and PI4KIIIα that stimulate the synthesis of PI(4)P anchor non-muscle myosin II RLC (Sqh) to the plasma membrane and conversely Sqh associates with PI(4)P and facilitates its membrane localization during asymmetric division of neuroblasts.

    The Brm-HDAC3-Erm repressor complex suppresses dedifferentiation in Drosophila type II neuroblast lineages

    Chwee Tat Koe, Song Li ... Hongyan Wang
    A novel complex composed of various components of a chromatin remodeling complex, a chromatin remodeling factor and a transcription factor suppresses the dedifferentiation of intermediate neural progenitors back into neuroblasts in Drosophila.

    Steroid hormone induction of temporal gene expression in Drosophila brain neuroblasts generates neuronal and glial diversity

    Mubarak Hussain Syed, Brandon Mark, Chris Q Doe
    A steroid hormone acts directly on brain neural progenitors to coordinately alter gene expression and specify neuronal and glial cell types.

    A CDK1 phosphorylation site on Drosophila PAR-3 regulates neuroblast polarisation and sensory organ formation

    Nicolas Loyer, Elizabeth KJ Hogg ... Jens Januschke
    PAR-3/Baz function is regulated by CDK1 in asymmetrically dividing cells in the central and peripheral nervous system of Drosophila revealing direct regulation of cell polarity by the cell cycle machinery in the context of cell fate specification.
