  • Exon capture and RNA-seq

    Apologies if this has been covered before but I am new to this great forum.

    I want to combine exon capture which I have done on DNA with RNA seq.

    If anyone can point me to any pertinent literature or make any constructive comments, these would be welcomed.

    Maybe you could first explain to us why you would want to do this? It is a rather unusual suggestion, after all.

      Pathway specific RNA-Seq

      I am just wanting to look at certain pathways,
      This should then bring the cost persample down

        If, by "exon capture", you mean capturing all exons, you can get this easier by just pulling out polyadenylated RNA. This is what is usually done.

        Capture adds all the usual biases one knows from microarrays, and hence, RNA-Seq after capture will only give you what you would have gotten easier and cheaper with expression microarrays, unless you want to study sequence changes (RNA-editing, coding SNPs, or the like).

        If you are only interested in a few genes, would not qPCR (analysed e.g. with HTqPCR package) or NanoStrings be cheaper, simpler and more accurate than capture and HTS?

          We are interested in the range of 200-500 genes.

          Because of their restricted dynamic range, arrays are not suitable.

          We have a limited amount of material, which precludes RT-qPCR.

          Nanostring would be appropriate but we do not have access to this methodology.

            Exploring the Dynamics of the Tumor Microenvironment
            by seqadmin




            The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

            Exploring Human Diversity Through Large-Scale Omics
            by seqadmin


            In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
