A C/EBPα–Wnt connection in gut homeostasis and carcinogenesisThis research reveals an antagonism between C/EBPα expression and activated Wnt signaling in the human and mouse gut and suggests a tumor suppressor function of C/EBPα in human and murine intestinal cancer.
Polycomb and Notch signaling regulate cell proliferation potential during Caenorhabditis elegans life cycleCaenorhabditis elegans lineage is invariant between animals. By challenging cell fate in differentiated worms, an unexpected role of Polycomb and Notch signaling in the control of cell proliferation was uncovered, suggesting that the lineage is more flexible than believed.
Mechanistic aspects of maltotriose-conjugate translocation to the Gram-negative bacteria cytoplasmA maltotriose-conjugate can deliver molecules into the cytoplasmic space of Gram-negative bacteria by parasitizing the maltose uptake pathway.
Evolution of gene expression levels in the male reproductive organs of Anopheles mosquitoesExpression patterns of transcripts in reproductive tissues reveal the phylogeny of the An. gambiae complex and are indicative of molecular function, transcription regulatory networks, and protein–protein interaction networks.
Rab1b and ARF5 are novel RNA-binding proteins involved in FMDV IRES–driven RNA localizationIntegration of proteomic data with functional and imaging analysis revealed that Rab1b and ARF5, two ER-Golgi members, are RNA-binding proteins that colocalize with picornavirus IRES-RNA reporters in human cells.
KIF18A's neck linker permits navigation of microtubule-bound obstacles within the mitotic spindleThe length of KIF18A's neck linker permits navigation of obstacles along K-fibers within the mitotic spindle and is required for the timely alignment and segregation of mitotic chromosomes.
A junction coverage compatibility score to quantify the reliability of transcript abundance estimates and annotation catalogsComparison of observed exon–exon junction counts to those predicted from estimated transcript abundances can identify genes with misannotated or misquantified transcripts.
Folding–function relationship of the most common cystic fibrosis–causing CFTR conductance mutantsThe tight correlation between folding and function in cystic fibrosis patients with CFTR mutations of the altered-conductance CFTR class provides an attractive paradigm for characterizing mode of action of novel therapeutics.
d-amino acid oxidase promotes cellular senescence via the production of reactive oxygen speciesThis study reveals a novel role of d-amino acid oxidase in promoting cellular senescence induced by genotoxic stresses via enzymatic generation of reactive oxygen species.
Viperin controls chikungunya virus–specific pathogenic T cell IFNγ Th1 stimulation in miceThis study shows that Viperin controls the microenvironment pro-inflammatory response and CD4 T cell–mediated pathogenesis during anti-chikungunya virus immune response in mice.
Loss of miR-210 leads to progressive retinal degeneration in Drosophila melanogasterDepletion of miRNA-210 disrupts photoreceptor integrity and visual function in Drosophila melanogaster.
Mitochondrial stress response triggered by defects in protein synthesis quality controlQuality control defects of mitochondrial nascent chain synthesis trigger a sequential stress response characterized by OMA1 activation and ribosome decay, determining mitochondrial form and function.
Reciprocal regulation of STING and TCR signaling by mTORC1 for T-cell activation and functionCostimulation of T cells through both TCR and STING induces growth inhibition by partially blocking the mTORC1 signals, and leads to IFN-I production through sustained activation of IRF3 and mTORC1 activation.
Redundant and nonredundant organismal functions of EPS15 and EPS15L1This study unveils a redundant function for the endocytic proteins Eps15 and Eps15L1 in mouse embryo development and erythropoiesis, and a unique nonredundant role for Eps15L1 in the nervous system.
Chromosome alignment maintenance requires the MAP RECQL4, mutated in the Rothmund–Thomson syndromeRECQL4, which is mutated in the Rothmund–Thomson syndrome characterized by premature aging and cancer susceptibility, is a microtubule-associated protein required for mitotic chromosome alignment.
DPP8/DPP9 inhibition elicits canonical Nlrp1b inflammasome hallmarks in murine macrophagesThis study shows that caspase-1 autocleavage, ASC speck assembly, and mature IL-1β and IL-18 secretion accompany rapid DPP8/DPP9-regulated pyroptosis induction in macrophages expressing a LeTx-responsive Nlrp1b allele.
Somatic recombination underlies frequent revertant mosaicism in loricrin keratodermaWe demonstrate that revertant mosaicism frequently occurs in loricrin keratoderma and that somatic recombination is the major mechanism underlying this therapeutically important phenomenon.
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.
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.
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.
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.
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.
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.
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.
