    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.

    Reassessment of weak parent-of-origin expression bias shows it rarely exists outside of known imprinted regions

    Carol A Edwards, William MD Watkinson ... Anne C Ferguson-Smith
    Genes with parent-of-origin specific expression are not as numerous as previously reported and validated parentally-biased expressed genes tend to be peripheral to known imprinted domains indicating shared regional control.

    IgM and IgD B cell receptors differentially respond to endogenous antigens and control B cell fate

    Mark Noviski, James L Mueller ... Julie Zikherman
    Self-reactive B cells downregulate the IgM but not the IgD B cell receptor, and this serves as a critical tolerance mechanism because IgD is less sensitive to bona fide endogenous antigens than IgM.

    Inherent regulatory asymmetry emanating from network architecture in a prevalent autoregulatory motif

    Md Zulfikar Ali, Vinuselvi Parisutham ... Robert C Brewster
    Network architecture and physiological features of the cell dictate asymmetric gene regulation between a negative autoregulatory TF gene and its target gene.

    Natural ITD statistics predict human auditory spatial perception

    Rodrigo Pavão, Elyse S Sussman ... José L Peña
    Human brain has incorporated natural statistics of spatial cues to the neural code supporting perception of sound location.

    Fetal and neonatal hematopoietic progenitors are functionally and transcriptionally resistant to Flt3-ITD mutations

    Shaina N Porter, Andrew S Cluster ... Jeffrey A Magee
    Age-specific transcriptional responses to Flt3-ITD and cooperating Flt3/Runx1 mutations cause hematopoietic stem cell depletion and myeloid progenitor expansion during adult, but not fetal/neonatal, stages of development.

    The role of the NMD factor UPF3B in olfactory sensory neurons

    Kun Tan, Samantha H Jones ... Miles F Wilkinson
    The nonsense-mediated RNA decay (NMD) branch-specific factor UPF3B influences olfactory sensory neuron cell populations, the olfactory receptor repertoire, and antimicrobial gene expression.

    Loss of full-length dystrophin expression results in major cell-autonomous abnormalities in proliferating myoblasts

    Maxime RF Gosselin, Virginie Mournetas ... Dariusz C Gorecki
    Loss of full-length dystrophin expression causes significant molecular and functional defects in human and mouse myoblast, thus closing the vicious cycle of DMD pathology.

    Imp/IGF2BP levels modulate individual neural stem cell growth and division through myc mRNA stability

    Tamsin J Samuels, Aino I Järvelin ... Ilan Davis
    Single molecule mRNA imaging uncovers post-transcriptional regulation of myc mRNA, via a cell-intrinsic mechanism allowing individualised control of neural stem cell proliferation during Drosophila brain development.

    RAB23 coordinates early osteogenesis by repressing FGF10-pERK1/2 and GLI1

    Md Rakibul Hasan, Maarit Takatalo ... David PC Rice
    RAB23 regulates calvarial bone and suture development both independently through, and by cross-talk between, Hedgehog and fibroblast growth factor signaling.
