A survey on identification and quantification of alternative polyadenylation sites from RNA-seq data

Abstract: Alternative polyadenylation (APA) has been implicated to play an important role in post-transcriptional regulation by regulating mRNA abundance, stability, localization and translation, which contributes considerably to transcriptome diversity and gene expression regulation. RNA-seq has become a routine approach for transcriptome profiling, generating unprecedented data that could be used to identify and quantify APA site usage. A number of computational approaches for identifying APA sites and/or dynamic APA … Show more

“…Future work will involve adding APA sites from more species and more diverse cell/tissue types upon the availability of new 39 seq data. Recently, a wide range of computational tools for identifying APA sites from RNA-seq data have continued to emerge, and an increasing number of APA sites have been found beyond annotated sites from 39 seq data (Chen et al, 2019). APA sites were also found from single-molecule sequencing (Wang et al, 2017(Wang et al, , 2018a.…”

“…Extensive bioinformatics efforts have been made to identify poly(A) sites or mRNA 3 tails using RNA-seq data. These previous bioinformatic tools have been classified into four groups based on their principles of the algorithms (Chen et al, 2020). Some of the programs have been compared using benchmarking datasets from model species (i.e., human, mouse, and Arabidopsis).…”

“…In particular, PolyA-Tag sequencing has been extensively used for genome-wide APA studies in higher plants, including Arabidopsis (Shen et al, 2011;Wu et al, 2011Wu et al, , 2016bHong et al, 2018), Chlamydomonas reinhardtii (Bell et al, 2016), rice (Fu et al, 2016;Ye et al, 2019;Zhou et al, 2019), and Medicago (Wu et al, 2014). In contrast to the experimental approaches targeting poly(A) tails and/or 3 UTRs, many bioinformatic methods and pipelines have been developed to identify poly(A) sites and/or detect differential APA usage between regular RNA-seq samples [reviewed by Chen et al (2020)]. These bioinformatics tools fall into four major types: type 1 tools include QAPA (Ha et al, 2018) and PAQR (Gruber et al, 2018) and rely on a pre-existed annotation of poly(A) sites, such as PolyA_DB (Lee et al, 2007), Polysite (Gruber et al, 2016), APASdb (You et al, 2014), and…”

“…Among multiple methods for bulk RNA-Seq data, we employ the approaches of DaPars 14 due to the following reasons. First, DaPars maintains highest sensitivity and specificity compared to other methods in benchmark tests on biological and simulation data 15 . Second, DaPars identifies APA genes without any assumption on the RNA-Seq signal density by determining 3'UTR isoforms such that the difference between the sum of the isoforms and the input RNA-Seq signal density is minimized (step 2 in Fig.…”
