p90 ribosomal S6 kinases play a significant role in early gene regulation in the cardiomyocyte response to G(q)-protein-coupled receptor stimuli, endothelin-1 and α(1)-adrenergic receptor agonists.

ERK1/2 (extracellular-signal-regulated kinase 1/2) and their substrates RSKs (p90 ribosomal S6 kinases) phosphorylate different transcription factors, contributing differentially to transcriptomic profiles. In cardiomyocytes ERK1/2 are required for >70% of the transcriptomic response to endothelin-1. In the present study we investigated the role of RSKs in the transcriptomic responses to the G(q)-protein-coupled receptor agonists endothelin-1, phenylephrine (a generic α(1)-adrenergic receptor ag ...[more]

Transcriptional profiling by array to study the effect of adenoviruses encoding the FLAG epitope or full-length antisense sequence to Atf3 on transcriptional regulation in rat cardiac myocytes

Project description:Cardiomyocytes, the terminally-differentiated contractile cells of the heart, undergo hypertrophic growth in response to endothelin-1. This is associated with changes in mRNA expression of immediate early genes (IEGs). Atf3 is a member of the ATF/CREB family transcription factors which bind as dimers to the cAMP response element (CRE). Atf3 mRNA is particularly associated with cell stress responses and is implicated in negative feedback regulation of gene expression. We confirmed that endothelin-1 promotes expression of Atf3 mRNA and protein in cardiomyocytes and that it is an IEG. Atf3 expression was transient and maximal at 0.5-1 h. We used adenoviruses for expression of antisense Atf3 RNA in cardiomyocytes to inhibit upregulation of Atf3 protein in response to endothelin-1. The effects on the cardiomyocyte transcriptome in control cells and cells exposed to endothelin-1 were examined using Affymetrix rat exon 1.0 ST arrays with data analysis using GeneSpring GX11.5. We identified transcripts that were upregulated by endothelin-1 for which antisense Atf3 significantly (FDR<0.05) enhanced or inhibited expression, respectively. The basal levels of other transcripts that are upregulated by endothelin-1 were also increased by antisense Atf3, though antisense Atf3 had no further effect on the response to endothelin-1. The data were validated by quantitative PCR of selected IEG mRNAs examining the effects at different times.

Magoh, Y14, eIF4AIII interactomes by TurboID proximity labelling provide no evidence for a canonical EJC in (almost) intron-less trypanosomatids

Project description:In metazoans, mRNA quality is tightly monitored from transcription to translation. A key role lies with the exon junction complex (EJC) that is placed upstream of the exon-exon junction after splicing. The EJC inner core is composed of Magoh, Y14, eIF4AIII and BTZ and the outer core of proteins involved in mRNA splicing (CWC22), export (Yra1), translation (PYM) and non-sense mediated decay (NMD, UPF1/2/3). The protozoan parasite Trypanosoma brucei encodes only two genes with introns, but all mRNAs are processed by trans-splicing. The presence of the three core EJC proteins and a potential BTZ homologue (Rbp25) in trypanosomes has been suggested as an adaptation of the EJC function to mark trans-spliced mRNAs. Here we explore the interactome of Magoh, Y14, eIF4AIII in T. brucei by TurboID proximity labelling.
