FUS (fused in sarcoma) is a component of the cellular response to topoisomerase I–induced DNA breakage and transcriptional stressThis work shows that the ALS-associated protein FUS is a component of the cellular response to transcriptional stress induced by topoisomerase I–induced DNA breakage, thereby accumulating at sites of nucleolar rRNA synthesis.
Main constraints for RNAi induced by expressed long dsRNA in mouse cellsA systematic survey of dsRNA expression in mouse fibroblasts and embryonic stem cells shows main constraints for RNAi. RNAi activity depends on the initial Dicer cleavage of dsRNA, having implications for the evolution of mammalian RNAi functions.
MiR-146a wild-type 3′ sequence identity is dispensable for proper innate immune function in vivoMice engineered to express an allele of a mammalian microRNA in which the 3′ paring specificity of the mature miRNA is robustly altered are phenotypically indistinguishable from mice with the wild-type allele.
Opposing Roles of apolipoprotein E in aging and neurodegenerationThis study investigates how APOE modulates neuronal function integrity during normal aging and in the context of amyloidosis. This work demonstrates that APOE is a necessary partner of Aβ-dependent neuronal dysfunction and synaptotoxicity but also preserves neuronal network during aging.
An essential role for α4A-tubulin in platelet biogenesisAlpha4A-tubulin is the predominant α-tubulin isotype in platelets. Mutations in α4A-tubulin cause abnormal platelet biogenesis and marginal band formation in mice and in a patient, establishing an essential role of this tubulin isotype.
Mucosa-associated microbiota drives pathogenic functions in IBD-derived intestinal iNKT cellsPro-inflammatory iNKT cells are enriched in IBD patients’ lamina propria. Exposure to the mucosa-associated microbiota drives their activation, inducing pathogenic activities against the epithelium.
Epithelial polarization in 3D matrix requires DDR1 signaling to regulate actomyosin contractilityFor epithelial cells to establish epithelial polarity in a 3D matrix, signaling of a collagen receptor tyrosine kinase, DDR1, plays a crucial role. DDR1 signaling controls actomyosin contractility at the cell–cell junction through suppression of ROCK activity.
Vamorolone targets dual nuclear receptors to treat inflammation and dystrophic cardiomyopathyVamorolone is a first-in-class dissociative drug that selectively targets the glucocorticoid receptor to safely treat chronic inflammation and the mineralocorticoid receptor to treat cardiomyopathy, providing efficacy with improved safety in mouse models of Duchenne muscular dystrophy.
Mitochondrial acetyl-CoA reversibly regulates locus-specific histone acetylation and gene expressionThis study shows that genetic or pharmacological manipulation of the TCA cycle, when mitochondria are dysfunctional, can modulate histone acetylation and gene expression in the nucleus with physiological outcomes.
Centrosome guides spatial activation of Rac to control cell polarization and directed cell migrationThe centrosome acts as a controller by balancing the formation of centrosomal and acentrosomal microtubules, the modulation of focal adhesion signaling and the activation of local Rac1 at the cell front, which then coordinates cell polarization during directed cell migration.
