A twin UGUA motif directs the balance between gene isoforms through CFIm and the mTORC1 signaling pathway

ABSTRACT: To identify APA changes in Tsc1-cKO mice, cTag-PAPERCLIP was performed on pAAV-Camk2a-iCre injected Tsc1-WT and Tsc1-floxed cTag-PABP mice. To identify CPSF6-dependent PAS, PAPERCLIP was performed on shCPSF6-BE2C cells with/without doxycycline treatment.

cTag-PAPERCLIP Reveals Alternative Polyadenylation Promotes Cell-Type Specific Protein Diversity and Shifts Araf Isoforms with Microglia Activation

Project description:Alternative polyadenylation (APA) is increasingly recognized to regulate gene expression across different cell-types, but obtaining APA maps from individual cell-types typically requires prior purification, a stressful procedure that can itself alter cellular states. Here, we describe a new platform, cTag-PAPERCLIP, that generates APA profiles from single cell populations in intact tissues; cTag-PAPERCLIP requires no tissue dissociation and preserves transcripts in native states. Applying cTag-PAPERCLIP to profile four major cell-types in the mouse brain revealed common APA preferences between excitatory and inhibitory neurons distinct from astrocytes and microglia, regulated in part by neuron-specific RNA-binding proteins NOVA2 and PTBP2. We further identified a role of APA in switching Araf protein isoforms during microglia activation, impacting production of downstream inflammatory cytokines. Our results demonstrate the broad applicability of cTag-PAPERCLIP and a previously undiscovered role of APA in contributing to protein diversity between different cell-types and cellular states within the brain.

Transcriptomic analysis of cortex tissue from neuron-specific Bmal1 KO mice

Project description:The circadian clock protein Bmal1 is critical for maintain circadian transcriptional funciton and rhythms. Global deleiton of Bmal1 renders whole mice behaviorally arrhythmic. However, cell-specific deletion of Bmal1 can reveal specific transcripts regulated by Bmal1 in a cell-specific manner. Here we used a BAC-transgenic Camk2a-iCre line to delete Bmal1 in a pan-neuronal manner. This mouse has previously been shown to have widespread Bmal1 deletion in neurons and to be arrhythmic (PMID: 25525750). We performed bulk RNAseq on cerebral cortex tissue from Camk2a-iCre+;Bmal1(fx/fx) and Cre- control littermates. Appropriate Bmal1 targets were disregulated as expetced in these mice. Pathways analysis revealed transcripts involved in Parkinson Disease and oxidative phosphorylation to be enriched.

Differential 3’ Processing of Specific Transcripts Expands Regulatory and Protein Diversity Across Neuronal Cell Types

Project description:Alternative polyadenylation (APA) regulates mRNA translation, stability, and protein localization. However, it is unclear to what extent APA regulates these processes uniquely in specific cell types. Using a new technique, cTag-PAPERCLIP, we discovered significant differences in APA between the principal types of mouse cerebellar neurons, the Purkinje and granule cells, as well as between proliferating and differentiated granule cells. Transcripts that differed in APA in these comparisons were enriched in key neuronal functions and many differed in coding sequence in addition to 3’UTR length.

The transcriptome-wide CPSF6-induced APA alterations in gastric cancer cells

Project description:In this study, we showed that knockdown of CPSF6 inhibited GC cell growth and promoted apoptosis in vitro and in vivo. In order to understand the underlying mechanisms of CPSF6, we performed an APA profiling analysis in wild-type and CPSF6-knockdown AGS cells, using 3T-seq method.

The transcriptome-wide CPSF6-induced APA alterations in HCC cells

Project description:In this study, we showed that CPSF6 promoted HCC cell growth, migration and metastasis in vitro and in vivo. In order to understand the underlying mechanisms of CPSF6, we aimed to perform a APA profiling analysis in hepatocyte and hepatoma carcinoma cells under different CPSF6 expression conditions using 3T-seq method.

Timecourse of epileptogenesis in an TSC1 inducible mouse model

Project description:To determine how the loss of TSC induces epileptogenesis, we made use of an inducible Tsc1 knock-out mouse model. Tsc1 was homozygously deleted in all CAMK2A positive neurons. Hippocampal tissue was collected at different time points after gene deletion and during epileptogenesis, of mice of both sexes. Also, mice treated with 10mg/kg rapamycin were included in the experiment. Using RNA-seq analysis, we identified differentially expressed genes encoding either ion channel and/or genes belonging to the GO-term ‘action potential’. Of these genes, 50% were already significantly dysregulated before or just around seizure onset, suggesting that these genes could be driver genes of epileptogenesis. Of the genes encoding ion channels or belonging to the Gene Ontology term action potential, 27 were differentially expressed just before seizure onset, suggesting a potential driving role in epileptogenesis. Our data highlight the complex changes driving epileptogenesis in TSC, including the changed expression of multiple ion channels. Our study emphasizes inhibition of the TSC/mTOR signaling pathway as a promising therapeutic approach to target epilepsy in patients with TSC.

PAPERCLIP identifies novel microRNA targets and provides insights into mRNA alternative polyadenylation

Project description:Accurate and precise annotation of the 3â² untranslated regions (3â² UTRs) is critical in understanding how mRNA stability, localization and translational efficiency are regulated by microRNAs (miRNAs) and RNA-binding proteins (RBPs). Here we describe a novel method, PAPERCLIP (Poly(A) binding Protein-mediated mRNA 3Â´End Retrieval by CrossLinking ImmunoPrecipitation), which shows high specificity for the mRNA 3â² ends and compares favorably to existing 3â² end mapping methods including direct RNA sequencing in performance. PAPERCLIP protocol and RNA-Seq on human cell lines and mouse whole brain cortex.
