A multiomics framework for high-throughput lncRNA characterization uncovers major immune regulators

ABSTRACT: Long noncoding RNAs (lncRNAs) play crucial roles in eukaryotic biology, yet their functions in the immune system are not fully understood. This study presents a comprehensive resource on the regulation, pathway dependencies, subcellular localizations, and protein interactomes of lncRNAs in immune cells exposed to pathogens. We developed GRADR, a methodology combining gradient profiling and RNA-bound proteome analysis, to map interactomes for all expressed RNAs in a single experiment. Using GRADR and targeted CRISPR multiomics, we identified a network of lncRNAs, including LINC01215, AC022816, and LINC01268 (ROCKI), that influence immunity, mainly through interactions with splicing factors. Our data are compiled into SMyLR, a web interface providing access to our lncRNA regulation and interactome atlas. This resource is expected to significantly advance research into RNA regulation in immunity.

CAP1-KO E18.5 mouCAP1-KO E18.5 mouse cerebral cortices LC-MSMS

Project description:Serum response factor (SRF) is a ubiquitously expressed transcription factor that is essential for brain development and function. SRF activity is controlled by two competing classes of coactivators, myocardin-related transcription factors (MRTF) and ternary complex factors, which introduce specificity into gene expression programs. Here, we explored the MRTF-mediated regulatory mechanism in mouse cortical neurons. Using gene-reporter assays and pharmacological and genetic approaches in isolated mouse cortical neurons, we found that cyclase-associated protein 1 (CAP1) repressed neuronal MRTF-SRF activity. CAP1 promoted cytosolic retention of MRTF by controlling cytosolic G-actin levels that required its helical folded domain and its CARP domain. This function of CAP1 was not redundant with that of its homolog CAP2 and was independent of cofilin1 and actin-depolymerizing factor. Deep RNA sequencing and mass spectrometry in cerebral cortex lysates from CAP1 knockout (CAP1-KO) mice supported the in vivo relevance for the CAP1-actin-MRTF-SRF signalling axis. Our study identified CAP1 as a repressor of neuronal gene expression and led to the identification of likely MRTF-SRF target genes in the developing cerebral cortex, whose dysregulation may contribute to impaired formation of neuronal networks in CAP1-KO mice. Together with our previous studies that implicated CAP1 in actin dynamics in axonal growth cones or excitatory synapses, we established CAP1 as a crucial actin regulator in neurons.

One-shot analysis of translated mammalian lncRNAs with AHARIBO

Project description:A vast portion of the mammalian genome is transcribed as long non-coding RNAs (lncRNAs) acting in the cytoplasm with largely unknown functions. Surprisingly, lncRNAs have been shown to interact with ribosomes, encode uncharacterized proteins, or act as ribosome sponges. These functions still remain mostly undetected and understudied owing to the lack of efficient tools for genome-wide simultaneous identification of ribosome-associated lncRNAs and peptide-producing lncRNAs. Here we present AHARIBO, a method for the detection of lncRNAs either untranslated, but associated with ribosomes, or encoding small peptides. Using AHARIBO in mouse embryonic stem cells during neuronal differentiation, we isolated ribosome-protected RNA fragments, translated RNAs and corresponding de novo synthesized polypeptides. Besides identifying mRNAs under active translation and associated ribosomes, we found and distinguished lncRNAs acting as ribosome sponges or encoding micropeptides, laying the ground for a better functional understanding of hundreds lncRNAs.

Conserved protein Pir2ARS2 mediates gene repression through cryptic introns in lncRNAs

Project description:Long non-coding RNAs (lncRNAs) are components of epigenetic control mechanisms that ensure appropriate and timely gene expression. The functions of lncRNAs are often mediated through associated gene regulatory activities, but how lncRNAs are distinguished from other RNAs and recruit effector complexes is unclear. Here we utilize the fission yeast Schizosaccharomyces pombe to investigate how lncRNAs engage silencing activities to regulate gene expression in cis. We find that invasion of lncRNA transcription into the downstream gene body incorporates a cryptic intron required for repression of that gene. Our analyses show that lncRNAs containing cryptic introns are targeted by the conserved Pir2ARS2 protein in association with splicing factors, which recruit RNA processing and chromatin modifying activities involved in gene silencing. Pir2 and splicing machinery are broadly required for gene repression. Our finding that human ARS2 also interacts with splicing factors suggests a conserved mechanism mediates gene repression through cryptic introns within lncRNAs.

Stress-induced lncRNA LAS3 fosters fitness of cancer cells by regulating SART3-mediated spliceosome recycling

Project description:Long non-coding RNAs (lncRNAs) represent a novel class of anti-cancer therapeutic targets. Hypoxia-induced lncRNAs are associated with the aggressive tumor phenotypes and might serve as putative drug targets. Here, we unraveled lncRNAs whose expression is upregulated in hypoxic breast tumors. One of the hypoxia-induced lncRNA, LAS3 (LncRNA Associated to SART3), is commonly upregulated not only in all breast cancer subtypes, but also in several types of epithelial cancers. LAS3 expression is driven by the stress-induced JNK/c-JUN pathway, which is frequently activated in human cancer. By pull down of LAS3 coupled to mass spectrometry-based proteomics, we identified SART3, a component of the splicing machinery, as a LAS3-interacting partner. In a second proteomics experiment, pull down of SART3-containing complexes from MCF10A cells treated with either scramble, or LAS3-specific GapmeRs showed that LAS3 regulates splicing efficiency by triggering SART3 dissociation from the U4/U6 snRNP during the recycling phase of the spliceosome cycle. Finally, differential shotgun analysis of MDA-MB-231/tet-shLAS3 cells allowed us to quantify expression of 2,940 proteins. Here, genes with significant intron retention showed decreased protein expression levels, indicating that widespread LAS3-mediated intron retention disrupts open reading frame integrity leading to stochastic decrease of protein expression and decreased fitness of cancer cells. Together, our data show that LAS3 is essential for growth of LAS3-positive triple negative breast tumors and indicate that LAS3 inhibition might be a suitable therapeutic approach for breast cancer treatment.

Transcription profiling of developmental time series for 10 different mutants with a combination of single and double mutants in 6 genes

Project description:We analyzed a developmental time course of ten different mutants with a combination of single and double mutants in 6 genes. The samples were collected at the following time points following starvation: 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22 and 24 hours. Dissimilarities between mutant time courses were measured by calculating both Euclidean distances and Pearson's correlation based distances between the scaled mutant time courses.

Long noncoding RNAs are spatially correlated with transcription factors and regulate lung development

Project description:To identify potential biological functions for three lncRNAs (NANCI, LL12, and LL34) we used shRNAs to knockdown expression of lncRNAs in MLE12 cells, a cell resembling type two lung epithelial cells. This data set contains the microarrays looking at gene expression. We used biological triplicate for each shRNA treatment and each treatment group was compared to a biological triplicate of MLE12 cells treated with a scrambled shRNA.

Writing and erasing O-GlcNAc on casein kinase 2 alpha alters the phosphoproteome

Project description:O-GlcNAc is an essential carbohydrate modification that intersects with phosphorylation signaling pathways via crosstalk on protein substrates or by direct modification of the kinases that write the phosphate modification. Casein kinase 2 alpha (CK2), the catalytic subunit of the ubiquitously expressed and constitutively active kinase CK2, is modified by O-GlcNAc, but the effect of this modification on the phosphoproteome in cells is unknown. Here, we apply complementary targeted O-GlcNAc editors, nanobody-OGT and -splitOGA, to selectively write and erase O-GlcNAc from a tagged CK2 to measure the effects on the phosphoproteome in cells. These tools effectively and selectively edit the S347 glycosite on CK2. Using quantitative phosphoproteomics, we report 51 proteins whose enrichment changes as a function of editing O-GlcNAc on CK2, including HDAC1, HDAC2, ENSA, SMARCAD1, and PABPN1. Specific phosphosites on HDAC1 S393 and HDAC2 S394, both reported CK2 substrates, are significantly enhanced by O-GlcNAcylation of CK2. These data will propel future studies on the crosstalk between O-GlcNAc and phosphorylation.

A conserved long intergenic non-coding RNA containing snoRNA sequences, lncCOBRA1, affects Arabidopsis germination and development

Project description:Long non-coding RNAs (lncRNAs) are an increasingly studied group of non-protein coding transcripts with a wide variety of molecular functions gaining attention for their roles in numerous biological processes. Nearly 6,000 lncRNAs have been identified in Arabidopsis thaliana but many have yet to be studied. Here, we examine a class of previously uncharacterized lncRNAs termed CONSERVED IN BRASSICA RAPA (lncCOBRA) transcripts that were previously identified for their high level of sequence conservation in the related crop species Brassica rapa, their nuclear-localization and protein-bound nature. In particular, we focus on lncCOBRA1 and demonstrate that its abundance is highly tissue and developmental specific, with particularly high levels early in germination. lncCOBRA1 contains two snoRNAs domains within it, making it the first sno-lincRNA example in a non-mammalian system. However, we find that it is processed differently than its mammalian counterparts. We further show that plants lacking lncCOBRA1 display patterns of delayed gemination and are overall smaller than wild-type plants. Lastly, we identify the proteins that interact with lncCOBRA1 and propose a novel mechanism of lincRNA action in which it may act as a scaffold with the RACK1A protein to regulate germination and development, possibly through a role in ribosome biogenesis.

Inhibiting coronavirus replication by chemical ER stress, including SARS-CoV-2 and MERS-CoV

Project description:Coronaviruses (CoVs) are important human pathogens for which no specific treatment is available. Here, we provide evidence that pharmacological reprogramming of ER stress pathways can be exploited to suppress CoV replication. We found that the ER stress inducer thapsigargin efficiently inhibits coronavirus (HCoV-229E, MERS-CoV, SARS-CoV-2) replication in different cell types, (partially) restores the virus-induced translational shut-down, and counteracts the CoV-mediated downregulation of IRE1α and the ER chaperone BiP. Proteome-wide data sets revealed specific pathways, protein networks and components that likely mediate the thapsigargin-induced antiviral state, including HERPUD1, an essential factor of ER quality control, and ER-associated protein degradation complexes. The data show that thapsigargin hits a central mechanism required for CoV replication, suggesting that thapsigargin (or derivatives thereof) may be developed into broad-spectrum anti-CoV drugs.
