Identification of sleep and circadian alternative polyadenylation sites associated with APA-linked human brain disorders

ABSTRACT: Disruption of sleep and circadian rhythms are a comorbid feature of many pathologies, and can negatively influence many health conditions, including degenerative disease, metabolic illness, cancer, and various neurological disorders. Genetic association studies linking sleep and circadian disturbances with disease susceptibility have mainly focused on changes in gene expression due to mutations, such as single-nucleotide polymorphisms. The interaction between sleep and/or circadian rhythms with the use of Alternative Polyadenylation (APA) has been largely undescribed, particularly in the context of other disorders. APA is a process that generates various transcript isoforms of the same gene affecting its mRNA translation, stability, localization, and subsequent function. Here we identified unique polyadenylation sites (PASs) expressed in rat brain over time-of-day, immediately following sleep deprivation, and the subsequent recovery period. From these data, we performed a meta-analysis of sleep- or circadian-associated PASs with recently described APA-linked brain disorder susceptibility genes.

QuantSeq FWD and QuantSeq REV using RNA samples from mouse NIH3T3 cells

Project description:Most eukaryotic genes harbor multiple cleavage and polyadenylation sites (PASs), leading to expression of alternative polyadenylation (APA) isoforms. APA regulation has been implicated in a diverse array of physiological and pathological conditions. While RNA sequencing tools that generate reads containing the PAS, named onSite reads, have been instrumental in identifying PASs, they have not been widely used. By contrast, a growing number of methods generate reads that are close to the PAS, named nearSite reads, including the 3’ end counting strategy commonly used in single cell analysis. How these nearSite reads can be used for APA analysis, however, is poorly studied. Here, we present a computational method, named model-based analysis of alternative polyadenylation using 3’ end-linked reads (MAAPER), to examine APA using nearSite reads. MAAPER uses a probabilistic model to predict PASs for nearSite reads with high accuracy and sensitivity, and examines different types of APA events, including those in 3’UTRs and introns, with robust statistics. We show usability of MAAPER with data from bulk RNA and single cell samples. Our result also highlights the importance of using well annotated PASs for nearSite read analysis.

A compendium of conserved cleavage and polyadenylation events in mammalian genes

Project description:Cleavage and polyadenylation is essential for 3’ end processing of almost all eukaryotic mRNAs. Recent studies have shown widespread alternative cleavage and polyadenylation (APA) events leading to mRNA isoforms with different 3’UTRs and/or coding sequences. Here we present a compendium of conserved cleavage and polyadenylation sites (PASs) in mammalian genes, based on ~1.2 billion 3’ end sequencing reads from over 360 human, mouse and rat samples. We show that ~80% of mammalian mRNA genes contain at least one conserved PAS, and ~50% have conserved APA events. PAS conservation generally reduces promiscuous 3’ end processing, stabling gene expression levels across species. Conservation of APA correlates with gene age, gene expression features, and gene functions. Genes with certain functions, such as cell morphology, cell proliferation, and mRNA metabolism, are particularly enriched with APA events. While tissue-specific genes typically have a low APA rate, brain-specific genes tend to evolve APA. We show enrichment of mRNA destabilizing motifs in alternative 3’UTR sequences, leading to substantial differences in mRNA stability between 3’UTR APA isoforms. Using conserved PASs, we reveal sequence motifs surrounding APA sites and a preference of adenosine at the cleavage site. Mutations of the U-rich motif around the PAS often accompany APA profile changes between species. Analysis of lncRNA PASs indicates a mechanism of PAS fixation involving evolution of A-rich motifs. Taken together, our results present a comprehensive view of PAS evolution in mammals, and a phylogenic understanding of APA functions.

Circadian Proteomics Landscape of Mouse Livers Organized by Time-restricted Feeding: Proteomics

Project description:Meal timing is essential in synchronization of circadian rhythms in different organ systems through clock-dependent and -independent mechanisms. The liver is a critical metabolic organ whose circadian clock and transcriptome can be readily reset by meal timing. However, it remains largely unexplored how circadian rhythms in the liver are organized in time-restricted feeding that intervenes meal timing. Here, we applied data-independent acquisition proteomics to characterize circadian features associated with day/sleep- (DRF) and night/wake (NRF)-time restricted feeding in nocturnal female mice. The transcriptomics and metabolomics datasets are public (see www.circametdb.org.cn).

The transcriptional terminator XRN2 and the RNA binding protein Sam68 link alternative polyadenylation to cell cycle progression in prostate cancer

Project description:Alternative cleavage and polyadenylation (APA) of pre-mRNAs yields multiple transcripts differing in their 3' end and its regulation is often aberrant in human cancers, including prostate cancer (PC). In this study, we have uncovered a novel mechanism of APA regulation which impinges on the functional interaction between the 5'-3' exonuclease XRN2 and the A/U-rich motif RNA binding protein Sam68 in PC cells. XRN2 promotes recruitment of Sam68 to its target transcripts, where it competes with the cleavage and polyadenylation specificity factor (CPSF) for the recognition of the AAUAAA core polyadenylation signal (PAS) motif. In particular, the Sam68/XRN2 complex suppresses the usage of strong canonical PASs at distal ends of genes and, consequently, promotes the usage of suboptimal proximal PASs.

Transcription profiling of mouse prefrontal cortex of C57Bl/6J mice at Zeitgeber Time (ZT) 3, 9, 15, and 21.

Project description:Background: The prefrontal cortex is important in regulating sleep and mood. Diurnally regulated genes in the prefrontal cortex may be controlled by the circadian system, by the sleep-wake states, or by cellular metabolism or environmental responses. Bioinformatics analysis of these genes will provide insights into a wide-range of pathways that are involved in the pathophysiology of sleep disorders and psychiatric disorders with sleep disturbances. Results: We examined gene expression in the mouse prefrontal cortex at four time points during the 24-hour (12-hour light:12-hour dark) cycle by microarrays, and identified 3,890 transcripts corresponding to 2,927 genes with diurnally regulated expression patterns. We show that 16% of the genes identified in our study are orthologs of identified clock, clock controlled or sleep/wakefulness induced genes in the mouse liver and SCN, rat cortex and cerebellum, or Drosophila head. The diurnal expression patterns were confirmed in 16 out of 18 genes in an independent set of RNA samples. The diurnal genes fall into eight temporal categories with distinct functional attributes, as assessed by the Gene Ontology classification and by the analysis of enriched transcription factor binding sites. Conclusions: Our analysis demonstrates that ~10% of transcripts have diurnally regulated expression patterns in the mouse prefrontal cortex. Functional annotation of these genes will be important for the selection of candidate genes for behavioural mutants in the mouse and for genetic studies of disorders associated with anomalies in the sleep:wake cycle and circadian rhythms. Experiment Overall Design: Prefrontal cortex from 3 biological replicates of C57BL/6J mice at four Zeitgeber Times (ZT 3, 9, 15, and 21) were analyzed
