Biotech Data Mining 33

Roland Piquepaille writes "In the last ten years, biotech companies have been busy accumulating mountains of data. And it's becoming more and more difficult to find useful information about interactions between genes and proteins for example. It's one of the reasons why the European Union has started the BioGrid project. In Mining biotech's data mother lode, IST Results describes this project. Among current results, the researchers involved in it have delivered a better search engine for PubMed by analyzing over-expressing genes and predicting the protein interactions that are likely occurring. And many of the tools developed by BioGrid are available for public use -- even by yourself. For more information, this overview contains additional details, pictures and references about this project."

    Hopefully this is the last Rololand Picapal article for the rest of the year.

    Lets celebrate by not clicking through to his poorly made blog!

    ... either way I don't win "karma".

    A lot of posts from here on out are implicit or explict observations that it is "New Years" at different times in different time zones all accross the globe. Just ignore them.

    Anyhow, for the on-topic part... the article describes what I think is reasonable follow-up to other research. E.g. Bio-tech is a science just like other, and needs to be confirmed and used as a starting point for further research.

    But that is boring to say.

  • I think these scientists deserve kudos, karma and lots of money. It's men and women that do boring jobs like this that will someday benifit humanity in ways we can't yet understand.
  • They have been accumualting lot of data. Well this is a forgone conclusion in any area of scientific research esepcially on of demand and has a direct relation to economic stability.

    The ability to search data for a highly pertinent area of research also a good idea. Perhaps the best ways to do this is not to establish one effective means of searching, but multiple.

    That being said just predicting results should be sufficient. It should be the means for basing an industry, and has proven to be succseful, in w

    ... and I'm not sure this data is that useful.

    What they're hoping for is to find commonalities among individuals with certain traits, genetic diseases obviously, but also predisposition for certain drug therapies. Medications work for some people and not for others. It would be marvelous if you could do a genetic scan of someone and predict whether a certain drug therapy would work on them. It could also bring drugs to market that aren't already because they don't help some people and are in fact dangerous to others.

    Great idea, but there are serious obstacles. First, the dataset that comes off a DNA sample is enormous. You can currently sample DNA in about 500,000 places, each location represented by letters, those letters representing the type of molecule present in a certain position on the double helix. There are about a half-dozen of those, so what you end up with is half a million of these letters juxtaposed. And it's not as easy as "if there's an n at position 232.922, this drug won't work for you." It's more like "if there's a series of letters in one place, and there's a series of letters in another, then you can either have a series in this place or a series that one, etc.".

    Unfortunately, you don't know how long the series is and you don't know where, you don't know what depends on what. You just don't know. It's a statistical nightmare. You should see the algorithms they throw at those things.

    And of course, environment may play a role in such things, too, so you don't even know if what you're looking for means anything.

    Great idea, hope it works, not holding my breath.

    • Actually, you can 'sample DNA' (I think you mean genotype) at any one of the 3 billion bases in the genome, provided you can develop an assay.

      The 500K you refer to could be from one of the (now standard) affymetrix 500K chips that have a standardized set of variants to test. They exclude a number of other markers, but via indirect evidence (knowledge of haplotype structure in the population), you can test other areas as well, and increase your coverage of the whole genome.

      I'll agree that the statistics are

  • There are a NUMBER of large scale efforts to perform the same in the US. I find it very weird that BioGrid, an European System is being tested on PubMed, a database maintained by the NIH/NCBI in the US. I am finding it weird that the author would choose to quote an obscure project in Europe. The integrated modeling of Biological systems is an extremely complicated problem, with data varying from sequence to microarray to literature to god knows what, and the author makes it look so simple. That is not the c
