  • Finding motifs in 5' of genes

    Hi,

    I have a list of differentially expressed genes that I would like to search for a 5' utr motif in them.
    What tool would you suggest to use or is there some kind of pipeline?

    Thanks in advance,
    Tamari

    I guess our workflow for this would be to use BioMart to pull out the UTR sequences and then use xxmotif to do the motif detection.

    You'll need to be careful about what you use as a control set of sequences for this analysis. We'd probably use a set of 5'UTRs from genes which were reasonably well expressed in your experimental system but which didn't change. Just doing a blind motif detection will likely find many spurious matches.

      Extract 5' UTR of your genes and there are several tools you can use:
      I usually use MEME but there are plenty more, see this Biostar discussion: Motif Finding / Biostar

        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...
