CapTrap-Seq: A platform-agnostic and quantitative approach for high-fidelity full-length RNA transcript sequencing

ABSTRACT: Here we describe CapTrap-Seq, an experimental workflow designed to address the problem of reduced transcript end detection by long-read RNA sequencing methods, especially at the 5' ends. We apply CapTrap-Seq to profile transcriptomes of the human heart and brain and we compared the obtained results with other library preparation approaches. CapTrap-Seq is a platform-agnostic method and here tested the method by using 3 different long-read sequencing platforms: MinION (ONT), Sequel (PacBaio) and Sequel II (PacBio).

INSTRUMENT(S): Illumina HiSeq 2500, MinION, Sequel, Sequel II

Identification of tens of thousands of novel gene loci in the human and mouse genomes through targeted full-length long-read RNA sequencing

Project description:The GENCODE project is a long-term international effort to produce a comprehensive and accurate map of genes and transcripts for the human and mouse genomes. While the annotation of protein-coding genes is nearly complete, long non-coding RNAs (lncRNAs) remain poorly characterized, with existing catalogs lacking consistency and experimental support. To address this, GENCODE used a targeted RNA sequencing approach to capture RNA from various human and mouse tissues, employing advanced sequencing technologies (ONT, PacBio, and Illumina). This resulted in the prediction of around half a million transcript models for both species. GENCODE then re-engineered its curation pipeline to handle this data, leading to the annotation of 16,817 new human genes (132,049 transcripts) and 22,210 new mouse genes (131,546 transcripts)—a significant increase in lncRNA annotations. The newly identified genes and transcripts have similar features to previously annotated lncRNAs and are linked to human phenotypes through GWAS and evolutionary conservation. Furthermore, the project has expanded the map of lncRNA orthology between humans and mice, especially for disease-associated lncRNAs. These updates enhance the functional interpretation of the human genome, connecting millions of previously unassigned omics data points (e.g., CAGE tags, ChIP-Seq peaks, genetic variants) to specific transcriptional units and regulatory regions. This marks a significant advancement toward a complete lncRNA catalog for human and mouse genomes.

Combining transcriptome and proteome analysis to identify and characterize the RpoS regulon in Pseudomonas fluorescens

Project description:Background: Microorganisms are the major cause of food spoilage during storage, processing and distribution. Pseudomonas fluorescens is a typical spoilage bacterium that contributes to a large extent to the spoilage process of proteinaceous food. RpoS is considered an important global regulator involved in stress survival and virulence in many pathogens. Our previous work revealed that RpoS contributed to the spoilage activities of P. fluorescens by regulating resistance to different stress conditions, extracellular acylated homoserine lactone (AHL) levels, extracellular protease and total volatile basic nitrogen (TVB-N) production. However, RpoS-dependent genes in P. fluorescens remained undefined. Results: RNA-seq transcriptomics analysis combined with quantitative proteomics analysis basing on multiplexed isobaric tandem mass tag (TMT) labeling was performed for the P. fluorescens wild-type strain UK4 and its derivative carrying a rpoS mutation. A total of 375 differentially expressed genes (DEGs) and 212 differentially expressed proteins (DEPs) were identified in these two backgrounds. The DGEs were further verified by qRT-PCR tests, and the genes directly regulated by RpoS were confirmed by 5’-RACE-PCR sequencing. The combining transcriptome and proteome analysis revealed a role of this regulator in several cellular processes, including polysaccharide metabolism, intracellular secretion and extracellular structures, cell well biogenesis, stress responses, ammonia and biogenic amine production, which may contribute to biofilm formation, stress resistance and spoilage activities of P. fluorescens. Moreover, in this work we indeed observed that RpoS contributed to the production of the macrocolony biofilm’s matrix.

Snapshot and temporal scRNA-seq of progenitor cells to dissect human embryonic stem cells entry into endoderm progenitors

Project description:Human pluripotent stem cells (hPSCs) offer a unique cellular model to study lineage specifications of the primary germ layers during human development. We profiled single-cell RNA-seq (scRNA-seq) on four lineage-specific progenitor cells derived from hESCs. Our scRNA-seq analyses revealed each type of progenitors display various extend of heterogeneity. Specifically, definitive endoderm cells (DECs) not only show a greater degree of heterogeneity, but are also enriched in metabolic signatures. Followed by detailed temporal scRNA-seq profiling along DEC differentiation, we reconstructed a differentiation trajectory using a novel statistical pipeline named Wave-Crest. Wave-Crest further identifies candidate regulators during the transitioning phase from Brachyury (T)+ mesendoderm towards CXCR4+ DEC state. To functionally test identified novel regulators; we generated a live cell monitoring system, a T-2A-EGFP knock-in reporter cell line via CRISPR/CAS9. We demonstrated that, among the top candidate genes, KLF8 plays a pivotal role modulating mesendoderm to DEC differentiation. In this submission, 1810 raw fastq files are provided; 212 are re-analysis from GSE64016. Four expected count matrices are provided - 1) 1018 single cells from snapshot progenitors; 2) 758 single cells from time couse profiling; 3) 19 bulk RNA-seq sample from snapshot progenitors; 4) 15 bulk RNA-seq sample from time course profiling. Total 1018 single cells from snapshot progenitors and 758 single cells from time couse profiling. Matchd population bulk RNA-seq samples for both the progenitors snapshot (19 samples) and time course profiling (15 samples) also included in this submission. These data set are used to detect the transitioning phase from mesendoderm to definitive endoderm.

Cappable-seq of Sinorhizobium meliloti ECF/anti-σ-free free strains overexpressing heterologous ecf genes compared to an empty vector control strain

Project description:Bacterial σ factors are dissociable subunits of the core RNA polymerase and important for promoter recognition and transcription initiation. Extracytoplasmic function (ECF) σ factors (σs) represent the most minimalistic and diverse group of alternative σs within the σ70 protein family. It has been shown that heterologous ECF σs hold great potential as context independent regulators in a variety of bacterial species and we implemented a core set of 12 heterologous ECF σs and their cognate promoters in Sinorhizobium meliloti. To analyze if heterologous ECF σs affect transcription from the host genome, we overexpressed the ecf02_2817 gene encoding σE from E. coli and the ecf11_0987 gene from Vibrio parahaemolyticus from ~20 copy number plasmid in RFF625c, a S. meliloti Rm1021 strain deleted for all native ECF/anti-σ genes (Lang et al. 2018, DOI: 10.1128/mSphereDirect.00454-18) . We employed Cappable-Seq to globally determine transcription start sites (TSS) in theses strains and compared it to the TSS profile of an empty vector control strain.
