    Behavioral-state modulation of inhibition is context-dependent and cell type specific in mouse visual cortex

    Janelle MP Pakan et al.
    The three main types of inhibitory neurons in mouse primary visual cortex respond differently to locomotion in darkness and during visual stimulation, revealing context-dependent responses to changes in behavioral state.

    Maternal Gdf3 is an obligatory cofactor in Nodal signaling for embryonic axis formation in zebrafish

    Brent W Bisgrove et al.
    Maternal Gdf3 and Nodal are interdependent obligatory cofactors in the fundamental patterning of the vertebrate embryonic axis of zebrafish.

    Paradoxical response reversal of top-down modulation in cortical circuits with three interneuron types

    Luis Carlos Garcia del Molino et al.
    Computational simulations and mathematical derivations reveal why the response of neural populations to external modulation is sometimes reversed with respect to what intuition would lead to believe in cortical circuits with multiple types of inhibitory neurons.

    Rapid DNA replication origin licensing protects stem cell pluripotency

    Jacob Peter Matson et al.
    The unique cell cycle variations of pluripotent stem cells ensures that the first step in DNA replication is particularly fast and this rapid rate, in turn, restrains early differentiation.

    Local processing in neurites of VGluT3-expressing amacrine cells differentially organizes visual information

    Jen-Chun Hsiang et al.
    Neurite arbors of VGluT3-expressing amacrine cells (VG3-ACs) process visual information locally uniformly detecting object motion while varying in contrast preferences; and in spite of extensive overlap between arbors of neighboring cells population activity in the VG3-AC plexus encodes stimulus positions with subcellular precision.

    CDK-regulated dimerization of M18BP1 on a Mis18 hexamer is necessary for CENP-A loading

    Dongqing Pan et al.
    The stoichiometry and mechanism of interactions of the Mis18 complex with M18BP1 was analysed to unveil the molecular basis of new CENP-A deposition during the G1 phase of the cell cycle.

    LAST, a c-Myc-inducible long noncoding RNA, cooperates with CNBP to promote CCND1 mRNA stability in human cells

    Limian Cao et al.
    A c-Myc-transcribed long noncoding RNA namely LAST (LncRNA-assisted stabilization of transcripts) collaborates with a cellular factor CNBP to promote the stability of CCND1/cyclin D1 mRNA post-transcriptionally, ensuring the proper G1/Sphase transition of the cell cycle.

    Cell cycle constraints on capsulation and bacteriophage susceptibility

    Silvia Ardissone et al.
    A multi-layered and conserved cell cycle mechanism prevents capsulation, long known as a bacterial virulence determinant, in G1-phase and concurrently licenses bacteriophage-mediated genetic exchange prior to entry into S-phase.

    Reliable cell cycle commitment in budding yeast is ensured by signal integration

    Xili Liu et al.
    The decision to commit to cell division-the Start transition-in budding yeast is governed by time integration of G1 cyclin-CDK activity by the transcription factor Whi5.

    An excitatory amacrine cell detects object motion and provides feature-selective input to ganglion cells in the mouse retina

    Tahnbee Kim et al.
    The mouse visual system is able to detect small moving objects due to the activity of VG3-amacrine cells, an unusual type of modulatory cell that uses the transmitter glutamate to activate retinal output cells.
