Description
Mammalian genomes are promiscuously transcribed, yielding protein-coding and non-coding products. Many transcripts are short-lived due to their nuclear degradation by the ribonucleolytic RNA exosome. Here, we show that abolished nuclear exosome function causes the formation of distinct nuclear foci, containing polyadenylated (pA+) RNA secluded from nucleocytoplasmic export. We asked whether exosome co-factors could serve such nuclear retention. Co-localization studies revealed the enrichment of pA+ RNA foci with 'pA-tail exosome targeting (PAXT) connection' components MTR4, ZFC3H1 and PABPN1, but no overlap with known nuclear structures, such as Cajal bodies, speckles, paraspeckles or nucleoli. Interestingly, ZFC3H1 is required for foci formation, and in its absence selected pA+ RNAs, including coding and non-coding transcripts, are exported to the cytoplasm in a process dependent on the mRNA export factor AlyREF. Our results establish ZFC3H1 as a central nuclear RNA retention factor, counteracting nuclear export activity. Overall design: Nuclear poly(A) selected RNA from HeLa cells was analysed by next generation sequencing upon depletion of EGFP(control) and RNA exosome core factor RRP40

Description
To assay the effect of depletion of the RNA exosome on RNAs shorter than the standard length captured by RNA-seq (>200 nt), we created RNA-seq libraries using fragmented RNA and a linker-ligation-based protocol that does not deplete RNAs shorter than 200 nt. Note: these data relate to Figure 6E in Lubas, Andersen et al., Cell Reports 2014 (accepted) Overall design: These samples constitute RNA-seq libraries prepared to enrich for short RNA fragments such as snRNA and snoRNAs. Three different HeLa cell RNAi experiments were used to generate the RNA samples applied in the library construction: control transfected, hRRP40-depleted and triple-depleted of the known RNA exosome-associated ribonucleases (DIS3, DIS3L and hRRP6 knock-down). By these means the data offers reveal RNA exosome substrates via their up-regulation in the respective knock-downs NOTE: The ''Figure6E_RNAseq_DataTable_PlottedValues.txt'' was generated from total 5 samples, with two additional published samples [SRP031620] and provided to better allow readers to fully replicate the analyses presented in the publication.

We report nuclear receptor Esrrb''s responsive genes with or without Esrrb ligand DY131 in DU145 cells. Using Esrrb-null cells, we used RNA-Seq to find Esrrb responsive genes. In addition, we tested DY131-driven Esrrb-dependent genes to test the ligand dependency of Esrrb in regulating gene expression. Overall design: Control vector transfected cells with vehicle treatment, Esrrb expression vector transfected cell with vehicle treatment, control vector transfected cells with DY131 treatment, Esrrb expression vector transfected cell with DY131 treatment.

Description
The unprecedented magnitude of the 2013-2016 Makona Ebola virus (M-EBOV) epidemic likely resulted from multiple epidemiologic factors that set it apart from previous outbreaks. Nonetheless, genetic adaptations that distinguish M-EBOV from previous isolates may also have contributed to the scale of the epidemic. Of particular interest is a M-EBOV glycoprotein (GP) variant, GP-A82V, that was first detected at the inflection point of the 2013-2016 outbreak - when the number of cases increased exponentially - and which completely supplanted the earlier M-EBOV sequence. We found that, as compared with the earlier strain, GP-A82V increased the ability of M-EBOV to fuse with and infect cells of primate origin, including human blood dendritic cells, without altering innate immune signaling in target cells. Residue 82 is located at the NPC1-binding site on M-EBOV GP and the increased infectivity of GP-A82V was restricted to cells from species in which the NPC1 orthologue bears primate-defining residues at the critical interface. We utilized HIV-derived lentiviral vectors pseudotyped with founder and A82V containing M-EBOV GPs to explore the potential that this modification alters how human monocyte-derived dendritic cells (MDDCs) respond to EBOV GP stimulation. Overall design: We generated stocks of lentiviral vector bearing one the following three M-EBOV GPs: founder, A82V, and A82V/T230A. These viral stocks were used to challenge MDDCs from two healthy, anonymous human donors. Stimulated MDDCs were harvested at 1, 2, 4, and 6 hours after viral addition. Gene expression in M-EBOV GP challenged MDDCs was compared to a unstimulated control.

Description
We had evidence that TRIM5 regulates signal transduction, specifically NFkB and MAPK pathways. To test the role of endogenous TRIM5 we used the myelomonocytic leukemia cell line THP1. These cells were transduced with a lentiviral vector that delivers a miRNA engineered to knockdown TRIM5. The vector also encoded a puromycin-resistance cassette and transduced cells were selected in poold with puromycin. As a control, cells were transduced with a vector targeting luciferase instead of TRIM5.

Description
gd T cells recognize unprocessed or non-peptide antigens, respond rapidly to infection, and localize to mucosal surfaces. We have hypothesized that the innate functions of gd T cells may be more similar to those of cells of the myeloid lineage than to other T cells. To begin to test this assumption, we have analyzed the direct response of cultured human and peripheral blood bovine gd T cells to pathogen associated molecular patterns (PAMPs) in the absence of APCs using microarray, real time RT-PCR, proteome array, and chemotaxis assays. Our results indicate that purified gd T cells respond directly to PAMPs by increasing expression of chemokine and activation related genes. The response was distinct from that to known gd T cell antigens and different from the response of myeloid cells to PAMPs. In addition, we have analyzed the expression of a variety of PAMP receptors in gd T cells. Freshly purified bovine gd T cells responded more robustly to PAMPs than did cultured human cells and expressed measurable mRNA encoding a variety of PAMP receptors. Our results suggest that rapid response to PAMPs through the expression of PAMP receptors may be another innate role of gd T cells.
