Post-transcriptional regulation of Ribosome Biogenesis during differentiation [SLAM-seq]

ABSTRACT: The regulation of ribosome biogenesis is a critical component of cell differentiation. Although ribosome biogenesis is well known to be regulated at the transcriptional level, its post-transcriptional regulation is less well understood. A key component of RNA post-transcriptional regulation is transcript decay rate which, together with the rate of synthesis, defines the abundance of the transcripts. Here we measured the stability of the whole transcriptome of P19 cells before differentiation (D0) and six days after the onset of differentiation (D6). We found that while global decay rates dropped during differentiation, the stability of transcripts encoding for ribosomal proteins remains significantly high throughout the differentiation process. These results indicate a strong and specific post-transcriptional regulation of ribosome biogenesis transcripts that is sustained during cell differentiation.

Post-transcriptional regulation of Ribosome Biogenesis during differentiation [dRNA-seq]

Project description:Ribosome biogenesis is a critical component of cell differentiation. Ribosome synthesis has been previously reported to be highly regulated at the transcriptional level, but less is known about its post-transcriptional regulation. Poly(A) tail length regulation is a hallmark of post-transcriptional regulation associated with transcript stability. Here we monitor poly(A) tail length changes at a transcriptome level during P19 differentiation. We found that poly(A) tail shortening occurs during cell differentiation only for transcript encoding for ribosomal proteins. These findings suggest a strong post-transcriptional regulation of ribosome biogenesis during differentiation.

Post-transcriptional regulation of Ribosome Biogenesis upon treatment with MHY1485

Project description:Ribosome biogenesis is a critical aspect of cell differentiation. Ribosome synthesis has been previously reported to be regulated at the transcriptional and post-transcriptional levels. Poly(A) tail-length processing is a hallmark of post-transcriptional regulation associated with different steps of transcript metabolism. Here we monitor the contribution of mTOR pathway activation upon treatment with the agonist MHY1485 in shaping the poly(A) tail profile of undifferentiated P19 cells. We found that transcripts with a 5' terminal oligopyrimidine (TOP) motif, including those encoding for ribosomal proteins, specifically accumulate with poly(A) tails ~60 nucleotides long upon mTOR activation.

Post-transcriptional regulation of Ribosome Biogenesis in Larp1-deficient cells

Project description:Ribosome biogenesis is a critical aspect of cell differentiation. Ribosome synthesis has been previously reported to be regulated at the transcriptional and post-transcriptional levels. Poly(A) tail-length processing is a hallmark of post-transcriptional regulation associated with different steps of transcript metabolism. Here we monitor the contribution of the RNA-binding protein Larp1 in shaping the poly(A) tail profile of undifferentiated P19 cells. We found that Larp1 prevents the widespread shortening of poly(A) tails below 30 nucleotides and confers additional protection to transcripts containing a 5' terminal oligopyrimidine (TOP) motif, such as those encoding for ribosomal proteins.

Inflammation-Induced Stabilization of mRNA in Rheumatoid Arthritis

Project description:<p>During rheumatoid arthritis (RA), TNF activates fibroblast-like synoviocytes (FLS) inducing in a temporal order a constellation of genes, which perpetuate synovial inflammation. Although the molecular mechanisms regulating TNF-induced transcription are well characterized, little is known about the impact of mRNA stability on gene expression and the impact of TNF on decay rates of mRNA transcripts in FLS. To address these issues we performed RNA sequencing and genome-wide analysis of the mRNA stabilome in RA FLS. We found that TNF induces a biphasic gene expression program: initially, the inducible transcriptome consists primarily of unstable transcripts but progressively switches and becomes dominated by very stable transcripts. This temporal switch is due to: a) TNF-induced prolonged stabilization of previously unstable transcripts that enables progressive transcript accumulation over days and b) sustained expression and late induction of very stable transcripts. TNF- induced mRNA stabilization in RA FLS occurs during the late phase of TNF response, is MAPK-dependent, and involves several genes with pathogenic potential such as IL6, CXCL1, CXCL3, CXCL8/IL8, CCL2, and PTGS2. These results provide the first insights into genome-wide regulation of mRNA stability in RA FLS and highlight the potential contribution of dynamic regulation of the mRNA stabilome by TNF to chronic synovitis.</p>

1 A post-transcriptional regulatory code for mRNA stability dur-ing the maternal-to-zygotic transition

Project description:Post-transcriptional regulation is crucial to shape gene expression. During the Maternal-to-Zygotic transition (MZT), thousands of maternal transcripts are regulated upon fertili-zation and genome activation. Transcript stability can be influenced by cis-elements and trans-factors, but how these inputs are integrated to determine the overall mRNA stability is unclear. Here, we show that most transcripts are under combinatorial regulation by multiple decay pathways. Characterization of the cis-regulatory motifs revealed that nu-cleotide composition bias characteristic of 3’-UTRs poly-U is associated with mRNA stability. In contrast, miR-430, CCUC, CUGC, elements appeared as the main destabiliz-ing motifs, with miR-430 and UAUUUAU (ARE) sequences causing mRNA deadenyla-tion depending on the activation of the genome. We comprehensively identify RNA-protein interactions across the transcriptome during MZT, and their associated regulatory activity. We find that poly-U binding proteins are preferentially associated with 3’-UTR sequences and stabilizing motifs. Analysis of differentially regulated regions revealed antagonistic sequence contexts for poly-C and poly-U binding proteins that shape protein binding and magnitude of regulation across the transcriptome. Finally, we integrate these regulatory motifs into a machine learning model, able to predict the stability of mRNA reporters in vivo. Our findings reveal how mechanisms of post-transcriptional regulation are coordinated to direct changes in mRNA stability within the early embryo.

Low RNA stability signifies increased post-transcriptional regulation of cell identity genes

Project description:Cell identity genes are distinct from other genes with respect to the epigenetic mechanisms to activate their transcription, e.g., by super-enhancers and Broad H3K4me3 domains. However, it remains unclear whether their post-transcriptional regulation is also unique. We performed a systematic analysis of transcriptome-wide RNA stability in nine cell types and found that unstable transcripts were enriched in cell identity-related pathways while stable transcripts were enriched in housekeeping pathways. Joint analyses of RNA stability and chromatin state revealed that significant enrichment of super-enhancers and broad H3K4me3 domains at the gene loci of unstable transcripts. Intriguingly, the RNA m6A methyltransferase, METTL3, preferentially binds to chromatin at super-enhancers, broad H3K4me3 domains, and their associated genes. METTL3 binding intensity is positively correlated with RNA m6A methylation and negatively correlated with RNA stability of cell identity genes, likely due to co-transcriptional m6A modifications promoting RNA decay. Nanopore direct RNA-seq showed that METTL3 knockdown has a stronger effect on RNA m6A and mRNA stability for cell identity genes. Our data suggest a run and brake model, where cell identity genes undergo both frequent transcription and fast RNA decay to achieve precise regulation of RNA expression.

Low RNA stability signifies strong expression regulatability of tumor suppressors

Project description:RNA expression of a gene is determined by not only transcriptional regulation, but also post-transcriptional regulation of RNA decay. The precise regulation of RNA stability in the cell plays an important role in normal development. Dysregulation of RNA stability can lead to diseases such as cancer. Here we found tumor suppressor RNAs tended to decay fast in normal cell types when compared with other RNAs. Consistent with a negative effect of m6A modification on RNA stability, we observed preferential deposition of m6A on tumor suppressor RNAs. Moreover, abundant m6A and fast decay of tumor suppressor RNAs both tended to be further enhanced in prostate cancer cells relative to normal prostate epithelial cells. Further, knockdown of m6A methyltransferase METTL3 and reader YTHDF2 in prostate cancer cells both posed stronger effect on tumor suppressor RNAs than on other RNAs. These results indicated a strong post transcriptional expression regulatability mediated by abundant m6A modification on tumor suppressor RNAs.

Pseudouridine-dependent ribosome biogenesis selectively regulates translation of polyglutamine proteins during Drosophila oogenesis [pulldown]

Project description:Stem cells in many systems, including Drosophila germline stem cells (GSCs), have increased ribosome biogenesis and translation during terminal differentiation. Here, we show that pseudouridylation of ribosomal RNA (rRNA) mediated by the H/ACA box is required for ribosome biogenesis and oocyte specification. Reducing ribosome levels during differentiation decreased the translation of a subset of mRNAs that are enriched for CAG repeats and encodes polyglutamine-containing proteins, including differentiation factors such as RNA-binding Fox protein 1. Moreover, ribosomes were enriched at CAG repeats within transcripts during oogenesis. Increasing TOR activity to elevate ribosome levels in H/ACA box-depleted germlines suppressed the GSC differentiation defects, whereas germlines treated with the TOR inhibitor rapamycin had reduced levels of polyglutamine-containing proteins. Thus, ribosome biogenesis and ribosome levels can control stem cell differentiation via selective translation of CAG repeat-containing transcripts.

Global RNA stability profiling reveals stabilization of P-body-enriched transcripts in the absence of human Dcp2

Project description:Multiple RNA decapping enzymes coexist in mammalian cells to regulate decay of distinct subsets of cellular transcripts, but their specificity remains incompletely defined to date. Here we present a global profile of RNA stability changes in human Dcp2 knockout cells via TimeLapse-seq. We demonstrate that P-body enrichment is the strongest correlate of Dcp2-dependent RNA decay, and that post-transcriptional modifications such as m6A present additive effect for Dcp2 targeting. Importantly, our data support a model in which P-bodies are sites that sort translationally repressed transcripts for cytoplasmic decay through additional molecular marks.
