A novel ALS-associated variant in UBQLN4 impairs proteasome function and beta-catenin degradation to drive aberrant axon morphogenesis in motor neurons.
Stem cell-derived motor neurons with differential ALS vulnerability identified proteasome activity as a possible mechanism that explains their differential sensitivity.
OptoGranules reveal the function of G3BP1 as a stress granule scaffold and demonstrate that protracted stress granule assembly is sufficient to drive neurodegeneration and the evolution of ALS-FTD pathology.
Computational models and software connect metagenomics to metabolic network reconstruction, assess metabolic complementarity between species, and identify critical species associated to functions of interest.
Motor axons undergo dynamic branch-specific changes for weeks before complete neuronal degeneration in a model of amyotrophic lateral sclerosis, highlighting the importance of peripheral factors, intrinsic and extrinsic to motoneurons.
During evolutionary progression of Alu-exons, repressive U-tracts buffer sudden gains in 3' splice site strength and prevent inclusion of cryptic exons.
Atrophic muscles of patients and animal models developing amyotrophic lateral sclerosis show an upregulation of TAp63 that stimulates the expression of a pro-atrophic ubiquitin ligase.
Zebrafish genetics and cryo-electron tomography reveal distinct roles of all vertebrate PIH family proteins in axonemal dynein assembly and cilia/flagella motions, assigning specific dynein subtypes to each PIH protein.
Reconstruction of great auk population dynamics suggests that hunting pressure alone could have been responsible for their extinction, demonstrating that even abundant, widespread species can be vulnerable to intense exploitation.
