A fibrillin-related protein, FBN-1, is a key component of the apical extracellular matrix and prevents epidermal cell deformation by biomechanical forces during morphogenesis of the C. elegans embryo.
APPPS1 microglia express disease-associated proteomic signatures of Alzheimer's disease earlier, compared to the APP-KI, and these differences correlate with the levels of fibrillar Aβ and impaired microglial phagocytic function.
Atomic structures of hIAPP fibrillar segments, determined using the cryo electron microscopy method MicroED, reveal that strong, stable intermolecular interactions are important features of cytotoxic amyloid proteins.
Integrative structural biology reveals a conformational equilibrium in the Box C/D methylation enzyme that regulates the extent of site-specific 2'-O-rRNA methylation in dependence of the RNA sequence.
Aβ inhibitors effectively block its aggregation, while also reducing seeding of tau aggregation from Aβ, tau, and AD derived fibrils, suggesting the two share a structurally related disease relevant interface.
Single molecule FISH analysis defines the behavior of centromere-derived alpha-satellite transcripts in intact human cells and reveals a critical role for centromere-nucleolar contacts in repressing alpha-satellite transcription.
Calcium channel blockers accelerate aortic aneurysm and cause premature aortic rupture in a mouse model of Marfan syndrome through protein kinase C-mediated activation of extracellular signal-regulated kinase.
