Description
Escherichia coli release Extracellular Vesicles (EVs) which carry diverse molecular cargo. Pathogenic E.coli EVs contain virulence factors which assist during infection in the host in different mechanisms.The RNA cargo of E.coli EVs has not been assessed in their effect in the host. We used microarray data to asses and compare the global response of bladder cells to EV-RNA from pathogenic E.coli (Uropathogenic UPEC 536) and non-pathogenic E. coli (probiotic Nissle 1917)

Description
Microglia are brain immune cells that constantly survey their environment to maintain homeostasis. Enhanced microglial reactivity and proliferation are typical hallmarks of neurodegenerative diseases. Whether specific disease-linked microglial subsets exist during the entire course of neurodegeneration, including the recovery phase, is currently unclear. Taking a single-cell RNA-sequencing approach in a susceptibility gene-free model of nerve injury, we identified a microglial subpopulation that upon acute neurodegeneration shares a conserved gene regulatory profile compared to previously reported chronic and destructive neurodegeneration transgenic mouse models. Our data also revealed rapid shifts in gene regulation that defined microglial subsets at peak and resolution of neurodegeneration. Finally, our discovery of a unique transient microglial subpopulation at the onset of recovery may provide novel targets for modulating microglia-mediated restoration of brain health. Overall design: scRNA-Seq was performed on microglial cells isolated from the ipsilateral and contralateral ventral pons of CX3CR1GFP/wt mice that underwent unilateral facial nerve axotomy at 12 weeks of age. The contralateral ventral pons of un-operated 12-week-old CX3CR1GFP/wt was used as baseline control (Day 0 post nerve transection) for the analysis. Three replicates were used per time point (Day 0, 7 and 30 post axotomy). mCEL-Seq2 protocol was used for single cell sequencing (Hashimshony et al. 2016, Herman et al. 2018).

Description
Recent research hints at an underappreciated complexity in pre-miRNA processing and regulation. Global profiling of pre-miRNA and its potential to increase understanding of the pre-miRNA landscape is impeded by overlap with highly-expressed classes of other non-coding RNA. Here we present a dataset excluding these RNA before sequencing through locked nucleic acids (LNA), greatly increasing pre-miRNA sequence counts with no discernable effects on pre-miRNA or mature miRNA sequencing. Analysis of profiles generated in total, nuclear, and cytoplasmic cell fractions reveals pre-miRNAs are subject to a wide range of regulatory processes involving loci-specific 3'- and 5'-end variation entailing complex cleavage patterns with co-occurring polyuridylation. Additionally, examination of nuclear-enriched flanking sequences of pre-miRNA, particularly those derived from polycistronic miRNA transcripts, provides insight into miRNA and miRNA-offset (moRNA) production. Our findings point to particularly intricate regulation of the let-7 family, introduce novel and unify known forms of pre-miRNA regulation and processing, and shed new light on the byproducts of miRNA processing pathways. none provided

Description
Mechanosensory hair cells (HCs) are the primary receptors of our senses of hearing and balance. However, very little is known about the transcriptional regulators involved in HC fate determination and differentiation. In this paper, we show that expression of three HC lineage-specific transcription factors: Gfi1, Pou4f3 and Atoh1, can induce a direct commitment towards HC fate during in vitro embryonic stem cell (ESC) differentiation. Induced HCs (iHCs) express numerous HC-specific genes and exhibit polarized membrane protusions reminiscent of stereociliary bundles.

Description
Unr (upstream of N-ras) is a cytoplasmic RNA-binding protein with cold shock domains, involved in regulation of messenger RNA stability and translation. To address the biological role of Unr, we inactivated the unr gene by homologous recombination in mice and embryonic stem (ES) cells. Embryos deficient for Unr die at mid-gestation, and the main phenotypic defects observed, growth deficiency and absence of neural tube closure, suggest a role of Unr in the balance proliferation/differentiation during early development. Here, we report that in Unr-null ES cell cultures, we observed a greater proportion of partially differentiated colonies, together with dispersed, refractile cells with stellate morphology, reminiscent of primitive endoderm (PrE) cells. DNA microarray, immunostaining, and RNA analyses revealed that Unr-null ES cells express a set of PrE markers, including the GATA6 transcription factor, a key inducer of PrE. Although Unr-deficient cells did not downregulate the pluripotency regulators Oct4, Nanog and Sox2, they grew more slowly than the wild-type lines, and their clonogenicity was lower. Silencing of Unr by RNA interference in ES E14 (129 genetic background) resulted in similar phenotypic and molecular changes as those observed in unr-/- ES cells (C57Bl/6 background). Finally, we show that ectopic expression of Unr in unr-/- ES cells partially reverses the endoderm-specific gene expression and the differentiation phenotype.

Description
The mammalian target of rapamycin (mTOR) is a central regulator of cell proliferation. Inhibitors of mTOR are being evaluated as anti-tumor agents. Given the emerging role of microRNAs (miRNAs) in tumorgenesis we hypothesized that miRNAs could play important roles in the response of tumors to mTOR inhibitors. Rapamycin resistant myogenic cells developed by long-term rapamycin treatment showed extensive reprogramming of miRNAs expression, characterized by up-regulation of the mir-17~92 and related clusters and down-regulation of tumor-suppressor miRNAs. Antagonists of oncogenic miRNA families and mimics of tumor suppressor miRNAs (let-7) restored rapamycin sensitivity in resistant tumor cells. This study identified miRNAs as new downstream components of the mTOR-signaling pathway, which may determine the response of tumors to mTOR inhibitors.
