From RNA to full-length transcripts: The PacBio Iso-Seq method for transcriptome analysis and genome annotation

A single gene may encode a surprising number of proteins, each with a distinct biological function. This is especially true in complex eukaryotes. Short- read RNA sequencing (RNA-seq) works by physically shearing transcript isoforms into smaller pieces and bioinformatically reassembling them, leaving opportunity for misassembly or incomplete capture of the full diversity of isoforms from genes of interest. The PacBio Isoform Sequencing (Iso-Seq™) method employs long reads to sequence transcript isoforms from the 5’ end to their poly-A tails, eliminating the need for transcript reconstruction and inference. These long reads result in complete, unambiguous information about alternatively spliced exons, transcriptional…

Full-length transcript profiling with the Iso-Seq method for improved genome annotations

Incomplete annotation of genomes represents a major impediment to understanding biological processes, functional differences between species, and evolutionary mechanisms. Often, genes that are large, embedded within duplicated genomic regions, or associated with repeats are difficult to study by short-read expression profiling and assembly. In addition, most genes in eukaryotic organisms produce alternatively spliced isoforms, broadening the diversity of proteins encoded by the genome, which are difficult to resolve with short-read methods. Short-read RNA sequencing (RNA-seq) works by physically shearing transcript isoforms into smaller pieces and bioinformatically reassembling them, leaving opportunity for misassembly or incomplete capture of the full diversity of…

Single cell isoform sequencing (scIso-Seq) identifies novel full-length mRNAs and cell type-specific expression

Single cell RNA-seq (scRNA-seq) is an emerging field for characterizing cell heterogeneity in complex tissues. However, most scRNA-seq methodologies are limited to gene count information due to short read lengths. Here, we combine the microfluidics scRNA-seq technique, Drop-Seq, with PacBio Single Molecule, Real-Time (SMRT) Sequencing to generate full-length transcript isoforms that can be confidently assigned to individual cells. We generated single cell Iso-Seq (scIso-Seq) libraries for chimp and human cerebral organoid samples on the Dolomite Nadia platform and sequenced each library with two SMRT Cells 8M on the PacBio Sequel II System. We developed a bioinformatics pipeline to identify, classify,…

AGBT Virtual Poster: Using the PacBio Iso-Seq method to search for novel colorectal cancer biomarkers

Early detection of colorectal cancer (CRC) and its precursor lesions (adenomas) is crucial to reduce mortality rates. The fecal immunochemical test (FIT) is a non-invasive CRC screening test that detects the blood-derived protein hemoglobin. However, FIT sensitivity is suboptimal especially in detection of CRC precursor lesions. As adenoma-to-carcinoma progression is accompanied by alternative splicing, tumor-specific proteins derived from alternatively spliced RNA transcripts might serve as candidate biomarkers for CRC detection.

Webinar: Chasing alternative splicing in cancer: Simplified full-length isoform sequencing

Tremendous flexibility is maintained in the human proteome via alternative splicing, and cancer genomes often subvert this flexibility to promote survival. Identification and annotation of cancer-specific mRNA isoforms is critical to understanding how mutations in the genome affect the biology of cancer cells. While microarrays and other NGS-based methods have become useful for studying transcriptomes, these technologies yield short, fragmented transcripts that remain a challenge for accurate, complete reconstruction of splice variants. The Iso-Seq method developed at PacBio offers the only solution for direct sequencing of full-length, single-molecule cDNA sequences needed to discover biomarkers for early detection and cancer stratification,…

User Group Meeting: Application of genome assembly in Bovinae species

In this PacBio User Group Meeting presentation, Tim Smith of the USDA’s Agricultural Research Service describes efforts to generate reference-grade genome assemblies for various bovine species and analyze them to understand factors such as how selective breeding has affected certain breeds. Genome assemblies he presents span cattle, water buffalo, and gaur. Smith shows data for each assembly, noting that as data production shifted to the Sequel System, long-read PacBio data became even better at producing highly contiguous assemblies.

User Group Meeting: The trials and tribulations of high quality human genome assembly

In this PacBio User Group Meeting presentation, Tina Graves-Lindsay of the McDonnell Genome Institute and the Genome Reference Consortium speaks about the importance of phasing human reference genomes. Her team is now working on its fifteenth human genome assembly — part of a major effort to improve genomic representation of ethnic diversity — with a pipeline that generates 60-fold PacBio coverage for a de novo assembly, followed by scaffolding with other technologies. They are also using FALCON-Unzip to separate haplotypes, leading to reference-grade diploid assemblies. This approach has already helped resolve errors seen in other genomes and even the gold-standard…

User Group Meeting: Development, validation, and applications of a high-fidelity, species-specific, eubacterial pan-domain microbiome assay on the PacBio System

In this PacBio User Group Meeting presentation, Garth Ehrlich of Drexel University College of Medicine shares his work on developing a microbiome assay that uses SMRT Sequencing to provide high-quality coverage of the 16S bacterial rRNA for species identification. The microbiome analysis pipeline, MCSMRT, takes advantage of PacBio circular consensus sequencing (CCS) technology and second-generation pathway analysis system for generating extremely high-fidelity sequences that provide the user with ultra-high-confidence species-level microbiome data.
