Canonical poly(A) polymerase activity promotes the decay of a wide variety of mammalian nuclear RNAs
  • organism-icon Homo sapiens
  • sample-icon 10 Downloadable Samples
  • Technology Badge IconIlluminaHiSeq2500

Description

The human nuclear poly(A)-binding protein PABPN1 has been implicated in the decay of nuclear noncoding RNAs (ncRNAs). In addition, PABPN1 stimulates hyperadenylation by poly(A) polymerase, and this activity is thought to be required for decay. Here, we inactivated hyperadenylation by two distinct mechanisms and examined changes in gene expression in HEK293 cells by RNAseq. We observed the upregulation of various ncRNAs, including snoRNA host genes, primary miRNA transcripts, and upstream antisense RNAs, confirming that hyperadenylation is broadly required for the degradation of PABPN1-targets. In addition, we found that mRNAs with retained introns are susceptible to PABPN1 and PAPa/?-mediated decay (PPD). Transcripts are targeted for degradation due to inefficient export, which is a consequence of reduced intron number or incomplete splicing. We conclude that PPD is an important mammalian nuclear RNA decay pathway for the removal of poorly spliced and nuclear-retained transcripts. Overall design: Poly(A)+ RNA from HEK293 cells was analyzed by next generation sequencing following depletion of PAPa and PAP? or expression of a dominant negative allele of PABPN1 (LALA) designed to inhibit polyadenylation. For each condition, we collected both total RNA and a nuclear-enriched sample. Each sample was collected in duplicate.

Gene expression in human endometrial cancer tissues and serous papillary endometrial cancer cell line, SPAC-1L, treated by STAT1-siRNA and/or IFN-gamma
  • organism-icon Homo sapiens
  • sample-icon 71 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

Endometrial cancer is one of the most common gynecologic malignancies, and patients with high grade disease, especially serous papillary subtype (SPEC) are often related to the poor outcomes. Recent genome-wide analyses have revealed that SPEC exhibits gene expression profiles that are distinct from the endometrioid histologic subtype; therefore, it is important to identify the SPEC driver genes or pathways responsible for the inherently aggressive phenotypes and to develop SPEC-specific therapies to target these driver genes or pathways.

STAT1 drives tumor progression in serous papillary endometrial cancer.

Tween 20 inducible genes
  • organism-icon Arabidopsis thaliana
  • sample-icon 6 Downloadable Samples
  • Technology Badge Icon Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)

Description

Polyethylene glycol sorbitan monoacylates (Tween) are detergents of widespread use in plant sciences. We show them, notably Tween 20, to cause a rapid and complex change in transcript abundance which bears all characteristics of a PAMP / elicitor-induced defense response, and they do so at concentrations which cause no detectable deleterious effects on plant cellular integrity. The activity does not reside in the intact Tween molecule itself, but is caused by medium-chain fatty acids, notably lauric acid (LA), which are efficiently released from the Tween-backbone by the plant. The Tween / LA-response is independent of the jasmonate signalling system. Medium-chain fatty acids are thus novel elicitors/regulators of plant pathogen defense. The results also have several practical implications: (i) The use of Tweens and, as we show, several other detergents, as solvating/wetting agents on intact plants causes profound physiological changes which may mask actual effects of test compounds; (ii) Tweens by themselves can be regarded (and probably used) as economical, non-toxic, and safe-to-apply elicitors of inducible plant immunity against pathogens.

Predominance of interferon-related responses in the brain during murine malaria as identified by microarray analysis.
  • organism-icon Mus musculus
  • sample-icon 4 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Genome 430 2.0 Array (mouse4302)

Description

Cerebral malaria (CM) can be a fatal manifestation of Plasmodium falciparum infection. We examined global gene expression patterns by microarray during fatal murine CM (FMCM) and non-cerebral malaria (NCM). There was differential expression of a number of genes, including some not yet characterized in the pathogenesis of FMCM. Some gene induction was observed during Plasmodium infection regardless of the development of CM and there was a predominance of genes linked to IFN responses, even in NCM. However, upon real-time PCR validation and quantitation, these genes were much more highly expressed in FMCM than in NCM. The observed changes included genes belonging to pathways such as interferon (IFN) signaling, MHC processing and presentation, apoptosis, immunomodulatory and anti-microbial processes. We further characterized differentially expressed genes by examining the cellular source of their expression as well as their temporal expression patterns during the course of malaria infection. These data identify a number of novel genes that represent interesting candidates for further investigation in FMCM.

Multiple Arkadia/RNF111 structures coordinate its Polycomb body association and transcriptional control
  • organism-icon Mus musculus
  • sample-icon 16 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2500

Description

The RING domain protein Arkadia/RNF111 is a ubiquitin ligase in the transforming growth factor beta (TGFß) pathway. We previously identified Arkadia as a small ubiquitin-like modifier (SUMO)-binding protein with clustered SUMO-interacting motifs (SIMs) that together form a SUMO-binding domain (SBD). However, precisely how SUMO interaction contributes to the function of Arkadia was not resolved. Through analytical molecular and cell biology, we found that the SIMs share redundant function with Arkadia''s M domain, a region distinguishing Arkadia from its paralogs ARKL1/ARKL2 and the prototypical SUMO-targeted ubiquitin ligase (STUbL) RNF4. The SIMs and M domain together promote both Arkadia''s colocalization with CBX4/Pc2, a component of Polycomb bodies, and the activation of a TGFbeta pathway transcription reporter. Transcriptome profiling through RNA sequencing showed that Arkadia can both promote and inhibit gene expression, indicating that Arkadia''s activity in transcriptional control may depend on the epigenetic context, defined by Polycomb repressive complexes and DNA methylation [Sun, Liu, and Hunter (2014) Mol Cell Biol 34(16):2981-2995]. Overall design: To determine the role of Arkadia in TGFß signaling at the transcriptome level, the profiles of TGFß-stimulated gene expression were examined in Ark+/+ (Ark_WT), Ark-/- (Ark_null), and Arkadia (WT and sim mutant)-reconstituted Ark-/- MEFs. RNA sequencing was carried out using poly(A)-enriched RNA samples from unstimulated cells and cells treated with TGFß for 1h, 4h, or 16h as indicated. Two batches of sequencing data for a total of 16 independent samples were submitted.

The DAXX co-repressor is directly recruited to active regulatory elements genome-wide to regulate autophagy programs in a model of human prostate cancer (RNA-seq)
  • organism-icon Homo sapiens
  • sample-icon 4 Downloadable Samples
  • Technology Badge IconIlluminaHiSeq2500

Description

This study was aimed at understanding the genome-wide binding and regulatory role of the DAXX transcriptional repressor, recently implicated in PCa. ChIP-Seq analysis of genome-wide distribution of DAXX in PC3 cells revealed over 59,000 DAXX binding sites, found at regulatory enhancers and promoters. ChIP-Seq analysis of DNA methyltransferase 1 (DNMT1), which is a key epigenetic partner for DAXX repression, revealed that DNMT1 binding was restricted to a small number of DAXX sites. DNMT1 and DAXX bound close to transcriptional activator motifs. DNMT1 sites were found to be dependent on DAXX for recruitment by analyzing DNMT1 ChIP-Seq following DAXX knockdown (K/D), corroborating previous findings that DAXX recruits DNMT1 to repress its target genes. Massively parallel RNA sequencing (RNA-Seq) was used to compare the transcriptomes of WT and DAXX K/D PC3 cells. Genes induced by DAXX K/D included those involved in autophagy, and DAXX ChIP-Seq peaks were found close to the transcription start sites (TSS) of autophagy genes, implying they are more likely to be regulated by DAXX. Overall design: Determine changes in gene expression levels between WT and DAXX K/D prostate cancer cells by RNA-Seq (PC3 Cells).
