    Dbx1 precursor cells are a source of inspiratory XII premotoneurons

    Ann L Revill et al.
    Building on previous work (Wang et al., 2014), we use a combination of genetic, electrophysiology and laser ablation approaches to identify a developmentally defined population of neurons that are a significant source of clinically relevant inspiratory drive to XII motoneurons.

    Purinergic regulation of vascular tone in the retrotrapezoid nucleus is specialized to support the drive to breathe

    Virginia E Hawkins et al.
    CO2/H+-dependent purinergic signaling by astrocytes provides specialized control of vascular tone in a brainstem respiratory center in a manner that contributes to respiratory behavior.

    Laser ablation of Dbx1 neurons in the pre-Bötzinger complex stops inspiratory rhythm and impairs output in neonatal mice

    Xueying Wang et al.
    Laser-ablating neurons of a single genetic class reveals that Dbx1-derived interneurons comprise core respiratory rhythmogenic and premotor circuits and provides quantitative cellular parameters that govern network functionality

    Motor control of Drosophila feeding behavior

    Olivia Schwarz et al.
    The neuroanatomical and functional analysis of genetically-identified motoneurons controlling all major steps of Drosophila proboscis extension provides new insights into the architecture of a motor circuitry controlling a reaching-like behavior.

    Operon mRNAs are organized into ORF-centric structures that predict translation efficiency

    David H Burkhardt et al.
    Operonic mRNAs in bacteria are comprised of ORF (open reading frame)-wide units of secondary structure, which are intrinsically distinct between adjacent ORFs and encode a rough blueprint for ORF-specific translation efficiency.

    The ribosomal protein Asc1/RACK1 is required for efficient translation of short mRNAs

    Mary K Thompson et al.
    Asc1/RACK1 promotes the translation of mRNAs associated with the translational closed loop complex, which have short open reading frames and encode proteins required for core metabolic processes.
