    All Human Non Coding RNA Foldings - Youtube Video

    While studying the results of sequencing tumor samples in various cancers, I noticed

    1) that there was strange transcription going on in "the middle of nowhere" and
    2) that there are often mutations in "long intergenic non-protein coding" RNAs, sometimes called "lincRNAs" or "Long ncRNAs".

    This small project deals with trying to figure out what these RNAs do. The initial focus us on lincRNAs. They are a subset of what is labeled as "miscellaneous rnas" (or "misRNAs").

    If you find a non-silent mutation in a protein encoding gene you might be able to deduce its impact by noting the gene's function and figuring out it's SIFT or polyphen score. You could fold the resulting protein and eye the damage. You could check what the gene's protein binds to or what network it's in.

    With non-coding RNA, your path to enlightenment is not well lit. There are new insights suggesting that some are involved in transcription, post-transcriptional modifications and epigenetic control. But many non coding RNAs are poorly understood. Mystery remains.

    Because little is known; I decided to "fold" all the "miscRNAs" in refseq and make them into a movie. These include lincRNAs, pseudogenes, anti-sense RNAs, and many "uncharacterized" RNA transcripts. The resulting video is ordered by these groups and gene name.

    The quick idea: use the human brain to see patterns. Are there motifs that can be tied to some meaning? Later, perhaps, I could use image processing techniques to subset the images, extract recurrent patterns and annotate these genes. Maybe an unknown gene might have a pattern that occurs in a better understood gene thus giving us a clue. For now, this is a just a first pass at trying to understand just what these RNAs do. Regardless, I just wanted a broad overview of the landscape ahead.

    The data was gathered from genbank flat files and processed using Vienna RNAfold, Gimp, Imagemacick and ffmpeg. All tools are available for Linux systems.

    Though the plot is thin, and the characters are one dimesional (well ... actually two dimesional) the videos are here ...

    The data for RNA folding of all refseq "miscRNAs" non-coding RNAs is from January 2013. There are 3996 RNAs in the series of videos.

    I hope there's some meaning to get from viewing all the foldings. I welcome any comments, even "dumb" ones. Sometimes they're not so dumb.

    Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
    by SEQadmin2



    Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

    Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

    New Genomics Technologies Take Aim at Long-Standing Limits
    by SEQadmin2


    Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

    We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
