    Mutant huntingtin impairs PNKP and ATXN3, disrupting DNA repair and transcription

    Rui Gao et al.
    Polyglutamine expansion in mutant huntingtin disrupts a novel transcription-coupled DNA repair complex, providing an undescribed mechanism of neuronal toxicity and degeneration in Huntington's disease.

    Reciprocal regulation of ARPP-16 by PKA and MAST3 kinases provides a cAMP-regulated switch in protein phosphatase 2A inhibition

    Veronica Musante et al.
    A complex interplay between MAST3 and PKA protein kinases and the regulatory protein ARPP-16 allows cAMP to control the activity of protein phosphatase 2A.

    Combined ALK and MDM2 inhibition increases antitumor activity and overcomes resistance in human ALK mutant neuroblastoma cell lines and xenograft models

    Hui Qin Wang et al.
    The combination of ceritinib with CGM097 demonstrates remarkable antitumor activity in TP53 wild-type neuroblastoma models with ALK aberrations and is able to overcome the resistance acquired during ceritinib treatment.

    A mutant with bilateral whisker to barrel inputs unveils somatosensory mapping rules in the cerebral cortex

    Nicolas Renier et al.
    The somatosensory cortex doesn't integrate mixed bilateral inputs, as partially uncrossing projections from the whiskers duplicates their representation by segregating lateralized inputs from each side of the head.

    A calcium transport mechanism for atrial fibrillation in Tbx5-mutant mice

    Wenli Dai et al.
    TBX5-loss associated cardiomyocyte ectopy and atrial fibrillation is prevented by augmentation of SERCA2 activity, establishing a mechanism underlying the genetic basis for a Ca2+-dependent pathway for AF risk.

    Harbouring public good mutants within a pathogen population can increase both fitness and virulence

    Richard J Lindsay et al.
    Cooperation theory and a novel synthetic infection system provides a mechanistic understanding of why a seemingly successful disease management strategy can have devastating consequences for infected hosts.

    The small molecule ISRIB rescues the stability and activity of Vanishing White Matter Disease eIF2B mutant complexes

    Yao Liang Wong et al.
    Vanishing White Matter Disease mutations compromise the function of the essential translation initiation factor eIF2B by destabilizing the holoenzyme, and the small molecule ISRIB reverses their pathogenic effect by promoting complex formation.

    Compensation for PKMζ in long-term potentiation and spatial long-term memory in mutant mice

    Panayiotis Tsokas et al.
    The enzyme PKMzeta is crucial for the maintenance of long-term memories, but a closely related enzyme provides a back-up should PKMzeta fail, thus explaining the controversy over why deleting the gene for PKMzeta may not appear to impair memory.
