Maternal circulating miRNAs that predict infant FASD outcomes influence placental maturationMaternal gestational circulating microRNAs, predictive of adverse infant outcomes, including growth deficits, following prenatal alcohol exposure, contribute to placental pathology by impairing the EMT pathway in trophoblasts.
Assessment and site-specific manipulation of DNA (hydroxy-)methylation during mouse corticogenesisThis work describes the dynamics of DNA modifications in specific cell types of the developing mammalian cortex. By providing a new method to manipulate this process in vivo, it is shown how this process can influence brain formation.
Worldwide genetic variation of the IGHV and TRBV immune receptor gene families in humansThis article presents a comprehensive study of the IGHV and TRBV gene families in a globally diverse sample of humans and shows that the two gene families exhibit starkly different patterns of variation.
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.
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.
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.
