Single-cell polyadenylation sequencing (scPolyA-seq) reveals the dynamic of polyA site usage during cell cycles in tumor cell lines [C1]

ABSTRACT: Alternative polyadenylation (APA) plays an important role in post-transcriptional gene regulation. But how genes' APA usages are influenced by cell cycle remains largely unknown. Here we developed single cell polyadenylation sequencing (scPolyA-seq), a strand-specific approach for sequencing 3’ end of transcripts which can get very deep sequencing level around polyA site for each cell, to investigate the landscape of APA at single cell level, based on Fluidigm C1. We compared APA changes before and after thymidine double blocking (TdR) synchronization of HeLa cells. We then identify 6 gene clusters whose distal polyA site usages fluctuate during cell cycle.

DNA Methylation Regulates Alternative Polyadenylation via CTCF and the Cohesin Complex

Project description:Alternative cleavage and polyadenylation (APA) is a form of transcriptional regulation via shifts in how frequently multiple polyadenylation (polyA) sites within genes are used across biological conditions. APA can result in transcripts with varying length and information content, and has been linked to gene regulation in both cancer and development. While trans-acting regulatory factors can cause changes in APA, the process of cleavage and polyadenylation is often co-transcriptional. We hypothesized that epigenetic changes, such as DNA methylation, may regulate APA co-transcriptionally. To identify genes where DNA methylation may regulate APA, we performed a genome-wide quantification of polyA site usage using a next generation sequencing technique. By priming the polyA-tails of an RNA library, we mapped cleavage sites and abundances with base-pair resolution across the genomes of two cell lines. The HCT116 cell line is derived from colon cancer, and contains cancer-associated DNA hypermethylation. The DKO cell line is derived from the parental HCT116 line, but has a near-complete depletion of DNA methylation due to mutations in DNA methyltransferase enzymes. Previous studies have used this sytem to detect genes where promoter DNA methylation regulates the gene expression of tumor suppressors. Analogously, detecting APA between HCT116 and DKO reveals candidate genes where DNA methylation may regulate the process of APA. Mechanistic experiments can further interrogate cross-talk between DNA methylation and APA at these loci, and contribute to the understanding of the function of non-promoter differentially methylated regions.

CPSF controls PAS selection and epidermal differentiation

Project description:Alternative polyadenylation (APA) is a regulatory mechanism that controls gene expression level and function through the usage of different transcription termination sites, but how APA is regulated to influence epidermal tissue differentiation remains under-characterized. Leveraging 3’READS+, we identified prevalent APA in keratinocytes. We further identified a high-confidence list of genes that alters their usages of polyadenylation site (PAS) during keratinocyte differentiation. To begin to understand the mechanisms that modulates PAS selection within a given gene, we identified that the expression of the Cleavage and Polyadenylation Specificity Factor (CPSF) complex is down regulated during keratinocyte differentiation. Suppression of CPSF using RNAi or CRISPRi strongly impaired epidermal regeneration with upregulation of terminal differentiation marker gene expression. Mechanistically, we identified that CPSF suppression decreased the usage of the GRHL3 proximal PAS and upregulated full-length GRHL3 mRNA production. Knockdown of GRHL3 in the context of CPSFi partially restored differentiation marker gene expression. We also found CPSF interacts with RNA-binding proteins to control PAS usage. Thus, our data suggest a model where CPSF binding preference and PAS choices regulate epidermal terminal differentiation.

Alternative cleavage and polyadenylation analysis in an isoform-resolved way by Second- and Third-Generation Sequencing technologies

Project description:Alternative cleavage and polyadenylation (APA) is emerging as an important mechanism of gene regulation in eukaryotes and plays important regulatory roles in human development and diseases. Despite the widespread application of Second Generation Sequencing (SGS) technology for polyadenylation site identification, matching each identified polyadenylation site within a gene to its derived isoform remains a major challenge. To achieve the isoform-resolved APA analysis, we developed a tool termed “IDP-APA” that constructs truly expressed isoforms and identifies polyadenylation sites by integrating the respective strengths of Third Generation Sequencing (TGS) long reads and SGS short reads. Compared to existing tools, IDP-APA demonstrated superior performance in both isoform reconstruction and polyadenylation site identification. Applications to human embryonic stem cells, breast cancer cells and brain tissue from a patient with Alzheimer’s disease revealed prevalent APA events and cell-/tissue-specific APA patterns, especially in an isoform-resolved way.

Activation and inhibition of nonsense-mediated mRNA decay control the abundance of alternative polyadenylation products

Project description:Alternative polyadenylation (APA) produces transcript 3’ untranslated regions (3’UTRs) with distinct sequences, lengths, stability, and functions. We show here that APA products include a class of cryptic nonsense-mediated mRNA decay (NMD) substrates with extended 3’UTRs that gene- or transcript-level analyses of NMD often fail to detect. Transcriptome-wide, the core NMD factor UPF1 preferentially recognizes long 3’UTR products of APA, leading to their systematic downregulation. Further, we find that many APA events consistently observed in multiple tumor types are controlled by NMD. Additionally, PTBP1, previously implicated in direct modulation of co-transcriptional polyA site choice, regulates the balance of short and long 3’UTR isoforms by inhibiting NMD. Our data suggest that PTBP1 binding near polyA sites can drive production of long 3’UTR APA products in the nucleus and/or protect them from decay in the cytoplasm. Together, our findings reveal a widespread role for NMD in shaping the outcomes of APA.

RNA polyadenylation landscape in human and mouse cells

Project description:Alternative polyadenylation (APA) of mRNAs has emerged as an important mechanism for post-transcriptional gene regulation in higher eukaryotes. Although microarrays have recently been used to characterize APA globally, they have a number of serious limitations that prevents comprehensive and highly quantitative analysis. To better characterize APA and its regulation, we have developed a deep sequencing-based method called Poly(A) Site Sequencing (PAS-Seq) for quantitatively profiling RNA polyadenylation at the transcriptome level. PAS-Seq not only accurately and comprehensively identifies poly(A) junctions in mRNAs and noncoding RNAs, but also provides quantitative information on the relative abundance of polyadenylated RNAs. We first analyzed HeLa cell transcriptome using PAS-Seq to demonstrate that PAS-Seq not only accurately and comprehensively identifies poly(A) junctions, but also provide quantitative information on the relativel abundance of APA isoforms. Next we analyzed the mouse embryonic stem cells, neural stem/progenitor cells, and neurons by PAS-Seq to characterize the dynamic changes of mRNA polyadenylation during stem cell differentiation.

Alternative Polyadenylation by Sequential Activation of Distal and Proximal PolyA Sites

Project description:Analogous to alternative splicing, alternative polyadenylation (APA) has long been thought to result from competition between proximal and distal polyA sites. By Fractionation-seq, we unexpectedly identified several hundred APA genes where their distal polyA isoforms are retained in chromatin/nuclear matrix and proximal polyA isoforms released into the cytoplasm. Global metabolic PAS-seq and Nanopore long-read RNA-seq provided further evidence that the strong distal polyA sites are first processed and the resulting transcripts are anchored in chromatin/nuclear matrix for further processing at proximal polyA sites and removal of certain slowly spliced introns. By engineering an autocleavable ribozyme between the proximal and distal polyA sites, we demonstrated that the distal polyA isoform is indeed the precursor to the proximal polyA isoform. Therefore, unlike alternative splicing, APA sites are recognized independently, rather than competitively, and in many cases, in a sequential manner. This provides a versatile strategy to regulate gene expression in mammalian cells.
