(Submitter supplied) Advances over the past decade have allowed for increasingly fine-grained labeling and isolation of rare cell samples for transcriptomic analysis, providing new insights into cell function and gene regulation. These samples often contain very little RNA for sequencing, and so have required new techniques to capture and amplify transcripts of interest. However, as new tools are developed, they are often optimized for mammalian samples. more...

(Submitter supplied) In a cross-site study we evaluated the performance of ribosomal RNA removal kits from Illumina, Takara/Clontech, Kapa Biosystems, Lexogen, New England Biolabs and Qiagen on intact and degraded RNA samples. We found that all of the kits were capable of performing significant ribosomal depletion, though there were differences in their ease of use. All kits were able to remove ribosomal RNA to below 20% with intact RNA and identify ~14,000 protein coding genes from the Universal Human Reference RNA sample at >1FPKM. more...

(Submitter supplied) Objectives: The sequencing by the PolyA selection is the most common approach for library preparation. With limited amount or degraded RNA, alternative protocols such as the NuGEN have been developed. However, it is not yet clear how the different library preparations affect the downstream analyses of the broad applications of RNA sequencing. Methods and Materials: Eight human mammary epithelial cell (HMEC) lines with high quality RNA were sequenced by Illumina’s mRNA-Seq PolyA selection and NuGEN ENCORE library preparation. more...

We also assayed the matched samples with Agilent microarray. RNA-seq data was compared on the rRNA-removal efficiency, genome profile, library complexity, coverage uniformity and quantitative cosinstency across protocols and with microarray data. more...

(Submitter supplied) In this study, we present a comprehensive evaluation of four RNA-Seq library preparation methods. We used three standard input protocols, the Illumina TruSeq Stranded Total RNA and TruSeq Stranded mRNA kits, and a modified NuGEN Ovation v2 kit; and an ultra-low-input RNA protocol, the TaKaRa SMARTer Ultra Low RNA Kit v3. Our evaluation of these kits included quality control measures such as overall reproducibility, 5’ and 3’ end-bias, and the identification of DEGs, lncRNAs, and alternatively spliced transcripts. more...

(Submitter supplied) RNA sequencing (RNA-seq) has become a standard method for quantifying gene expression transcriptome-wide. Due to the extremely high proportion of ribosomal RNA (rRNA) in total RNA, sequencing libraries usually incorporate messenger RNA (mRNA) enrichment. Although polyadenylate (poly(A)) tail selection is widely used, many applications require alternate approaches such as rRNA depletion. Recently, selective rRNA digestion, using RNaseH and antisense DNA oligomers that tile the length of target RNAs, has emerged as an easy, cost-effective alternative to commercial rRNA depletion kits. more...

(Submitter supplied) A major challenge for RNA-seq analysis of gene expression is to achieve sufficient coverage of informative non-ribosomal transcripts. In eukaryotic samples, this is typically achieved by selective oligo(dT)-priming of messenger RNAs to exclude ribosomal RNA (rRNA) during cDNA synthesis. However, this strategy is not compatible with prokaryotes in which functional transcripts are generally not polyadenylated. more...

(Submitter supplied) Much of posttranscriptional mRNA regulation occurs through cis-acting sequences in mRNA 3´ untranslated regions (UTRs), which interact with specific proteins and ribonucleoprotein complexes that modulate translation, mRNA stability and subcellular localization. Studies in Caenorhabditis elegans have revealed indispensable roles for 3´UTR-mediated gene regulation, yet most C. elegans genes have lacked annotated 3´UTRs. more...

(Submitter supplied) We tested a number of rRNA removal methods (Illumina RiboZero Plus, NEBNext, NEB Core Depletion Set with custom probes, siTools Panarchaea, siTools RiboPool) on 4 model halophile species: Halobacterium salinarum, Haloferax volcanii, Haloferax meditteranei, Haloarcula hispanica). It was found that methods using custom probes (NEB Core Depletion set with HVO probes, siTools RiboPool with HVO probes) efficiently remove rRNA in species they are targeted to, and that Panarchaea efficiently removes rRNA in all 4 tested species.

(Submitter supplied) The cell fate decisions between plasmablasts (PBs), germinal center B cells (GCBCs) and non-GC-derived early memory B cells (eMBCs) during early B cell activation determine the outcome of the immune responses to pathogens and vaccines. To characterize these poorly understood lineage choices, we dissected the early B cell responses to T-dependent antigen in mice by single-cell RNA-sequencing. Early after immunization, a homogenous population of activated precursors (APs) gave rise to a transient wave of PBs, followed a day later by the emergence of the first GCBCs, with the transcriptomes of both rapidly diverging from that of APs. more...

(Submitter supplied) Background: DNA microarrays provide a powerful method for global analysis of gene expression. The application of this technology to specific cell types and tissues, however, is typically limited by small amounts of available mRNA, thereby necessitating amplification. Here we compare microarray results obtained with two different methods of RNA amplification to profile gene expression in the C. elegans larval nervous system. more...

(Submitter supplied) Caenorhabditis elegans is a major eukaryotic experimental system employed to unravel a broad range of cellular and biological processes. Despite the many advantages of C. elegans, biochemical approaches to study tissue-specific gene expression in postembryonic stages are challenging. Here we report a novel experimental approach that enables the efficient determination of tissue-enriched transcriptomes by rapidly releasing nuclei from major tissues of postembryonic animals followed by fluorescence-activated nuclei sorting (FANS). more...

(Submitter supplied) Single-cell transcriptomics (scRNA-seq) has revolutionized our understanding of cell types and states in various contexts, such as development and disease. Most methodology relies on poly(A) enrichment to selectively capture protein-coding polyadenylated transcripts, intending to exclude ribosomal transcripts that constitute >80% of the transcriptome. However, it is common for ribosomal transcripts to sneak into the library, which can add significant background by flooding libraries with irrelevant sequences. more...

(Submitter supplied) The finding that small non-coding RNAs (sRNAs) can affect cellular processes by regulating gene expression had a significant impact on biology research and clinical diagnosis. Yet, the ability to quantify and profile sRNAs, especially miRNAs, using high-throughput sequencing is especially challenging because of their repetitive nature. We have developed QsRNA-seq a method for preparation of sRNA libraries for high-throughput sequencing that overcomes this difficulty by enabling separation of fragments differing only by 20nt in length and implementing barcode and unique molecular identifiers for multiplexing and accurate quantification. more...
