    High library diversity for ultra-low inputs

    D-Plex smRNA-seq captures the smRNA complexity of the sample in a sensitive manner. A large number of features is detected for each biotype at a CPM ≥5, as shown above for different species.

    Accurate representation of the smRNA content of a sample

    Accurate identification of PCR duplicates in low-input samples using unique molecular identifiers (UMIs).
    The UMI read deduplication that is embedded in the D-Plex construct is used to avoid over-estimation of transcripts by identifying clones generated during the PCR amplification of the library. Despite limiting starting RNA input, the UMI correction removed technical copies of transcripts, maintaining the initial sample abundance.

    D-Plex (template switching) technology enables recovery of the initial miRNA distribution of the miRXplore Universal Reference (Miltenyi Biotech Inc., Cat. No. 130-093-521). In contrast, ligation-based kits display a strong distortion of the miRNA equimolar distribution initially present in the pool, indicating sample incorporation bias.

    D-Plex smRNA-seq in association with the MGcount analysis correlates strongly (R² > 0.8) with the RT-qPCR analysis, which is considered the gold-standard for accuracy.
    The figures shows a fold-change accuracy of a panel of 20 different small-RNA (figure taken from MGcount publication - Hita et al., BMC bioinformatics, 23-39(2022).

    Maximize information from the regulatory transcriptome using D-Plex small RNA-seq kit and MGcount*

    By analyzing D-Plex dataset with MGcount, more reads are kept during the analysis, which ultimately preserves biological complexity linked to ncRNA expression without decreasing the accuracy of detection.

    The D-Plex technology uses two innovative ligation-free mechanisms, poly(A) tailing and template switching, to produce sequencing libraries from ultra-low input amounts.


    WORKFLOW


    RNA molecules are polyadenylated at the 3’-end and primed with an oligo(dT) primer containing part of the ILMN 3’-adapter sequence. The addition of a template-switching oligonucleotide during cDNA synthesis enables fusion of part of the ILMN 5’-adapter during reverse transcription. After PCR, the library comprises double stranded DNA constructs that are ready for sequencing.



  • データ解析

    A specific bioinformatics pipeline has been developed to process the special sequences present in the D-Plex construct, namely the UMI, the A-tail, and the template switch motif. All guidelines and free softwares are shared in the user manual. Subject to the compatibility of D-Plex constructs, other specific pipelines can be used.

    The counting or expression level calculation is the last step of the processing to generate an expression level matrix. We recommend using MGcount*, a counting tool developed at Diagenode with a suitable annotations file that include the small RNA transcripts that are object of study. MGcount, built on top of featureCounts, employs a flexible quantification approach to deal with datasets containing multiple RNA biotypes such as D-plex libraries. Non-coding RNAs varying in length, biogenesis, and function, may overlap in a genomic region, and are sometimes present in the genome with a high copy number. Consequently, reads may align equally well to more than one position in the reference genome or/and align to a position where more than one annotated transcript is located. MGcount employs two strategies to quantify these reads. Firstly, it assigns reads in rounds prioritizing small-RNAs over long-RNAs ensuring the unbiased read attribution to intergenic and intragenic small RNAs while preventing host-genes transcription over-estimation. Secondly, MGcount collapses loci where reads consistently multi-map into communities of loci with a graph-based approach. The resultant communities are groups of biologically related loci with nearly identical sequence. Subsequently, quantification of reads is performed at the loci-community level, reducing multi-alignments ambiguity at individual locus. Ultimately, this strategy maximizes the transcriptome information analysed and improves the interrogation of non-coding RNAs. MGcount software repository provides annotation files for A. thaliana, H. sapiens, M. musculus and C. elegans. The required input files for MGcount are a .txt file listing the paths to the alignment input files (.bam format) and the annotations file (.gtf format). The output directory path has to be provided as an input as well.

    Example command:

    MGcount -T 2 --gtf Homo_sapiens.GRCh38.gtf --outdir outputs --bam_infiles input_bamfilenames.txt

    MGcount provides the choice to enable/disable the quantification of all RNA biotypes included in the annotation file in the form of "communities" as optional parameters for small-RNA (--ml_flag_small) and long-RNA (--ml_flag_long). Both are enabled by default. The main output of MGcount is the count_matrix.csv file containing an expression matrix that can be imported to R or any other software for downstream analyses.
    A full user guide for MGCount is available here: https://filedn.com/lTnUWxFTA93JTyX3Hvbdn2h/mgcount/UserGuide.html.

    Other standard counting tools such as featureCounts or HTSeq-counts can also be used alternatively. Given the high complexity of D-Plex libraries, we recommend having a clear understanding of the scientific question and the goal of the project before proceeding to the choice of the counting method as this will strongly impact downstream analyses. Diagenode provides bioinformatics support as a service (please, contact us if you need help with data analysis).

    Notice that D-Plex produces forward-stranded data. Stranded libraries have the benefit that reads map to the genome strand where they were originated from. Therefore, when estimating transcript expression, reads aligned to the forward strand should be assigned only to transcript features in the forward strand whereas reads aligned to the reverse strand should be assigned only to transcript features in the reverse strand. For this, make sure you select “stranded mode” in any tool of choice. Stranded mode is selected by default in MGcount.

    Genes with 5′ terminal oligopyrimidine tracts preferentially escape global suppression of translation by the SARS-CoV-2 NSP1 protein
    Shilpa R. et al.
    Viruses rely on the host translation machinery to synthesize their own proteins. Consequently, they have evolved varied mechanisms to co-opt host translation for their survival. SARS-CoV-2 relies on a non-structural protein, NSP1, for shutting down host translation. Despite this, it is currently unknown how viral pr...

    Gylling HM, Gonzalez-Aguilera C, Smith MA, Kaczorowski DC, Groth A, Lund AH
    Non-coding RNA has a proven ability to direct and regulate chromatin modifications by acting as scaffolds between DNA and histone-modifying complexes.

    The ribosomal protein S1-dependent standby site in tisB mRNA consists of a single-stranded region and a 5′ structure element
    Romilly C. et al.
    In bacteria, stable RNA structures that sequester ribosome-binding sites (RBS) impair translation initiation, and thus protein output. In some cases, ribosome standby can overcome inhibition by structure: 30S subunits bind sequence-nonspecifically to a single-stranded region and, on breathing of the inhibitory struc...

    Fehlmann T, Backes C, Pirritano M, Laufer T, Galata V, Kern F, Kahraman M, Gasparoni G, Ludwig N, Lenhof HP, Gregersen HA, Francke R, Meese E, Simon M, Keller A
    The repertoire of small noncoding RNAs (sncRNAs), particularly miRNAs, in animals is considered to be evolutionarily conserved. Studies on sncRNAs are often largely based on homology-based information, relying on genomic sequence similarity and excluding actual expression data. To obtain information on sncRNA expres...
