First Whole Cancer Genome Sequenced 115

Posted by timothy from the gee-gnome-sounds-like-a-good-open-source-project dept.
dooling writes "A paper detailing the sequencing of the first human cancer genome will be published in the 6 November 2008 issue of Nature. This is not only the first cancer genome published, it is the first female genome as well. You can read the paper's abstract, DNA sequencing of a cytogenetically normal acute myeloid leukaemia genome, or the story in Science News. This issue of Nature also has articles on the sequencing of the first African and Asian genomes. The sequencing in all three articles was done using the Illumina Genome Analyzer, one of the massively parallel, next-generation genome sequencing platforms."

          On that note, countries with long lives tend to need to support a fair amount of old people, which makes kids expensive, and keeps birth rates down.

          Countries where birth rates are high and where life spans are short have a strong correlation. And they keep growing.

Every time they do divide, there is a small chance for mutation, and a small chance of that mutation to be deleterious to our health. Apparently, genetics and lifestyle effect how often and to what extent these mutations occur. This is why I don't think cancer will ever be 'cured'; it's a disease we can only delay.

        Basically (my total layman interpretation, go read the wikipedia article and others) the cell division is limited by the shortening telomere.

      I'm also concerned that these might be mutations in the hematopoietic stem cell that don't "drive" the disease. The lengthy points at the end debunking this possibility aren't convincing to me. Here are the 1st two (FTA):

      1) "genetic instability does not seem to be a general feature of AML genomes."

      Are they on crack? Perhaps I don't fully understand the context of this statement; genetic instability and evolution are seen in most cases of AML.

      2) "Alternatively, all may have occurred simultaneously in the same leukaemia-initiating cell, but only a subset of the mutations (or an as-yet undetected mutation) is truly important for pathogenesis (that is, disease 'drivers' versus passengers). Although we suggest that the latter hypothesis is very unlikely on the basis of our current understanding of tumour progression"

      Simultaneously occurring? Again, this flies in the face of common knowledge. The theory is the hematopoietic stem cell is extremely long lived and only divides once a year and so has plenty of time to accumulate genetic mutations. This explains both the average relapse time of one year and also the genetic homogeneity of the leukemic clone. Thus many of their new found eight mutations may be accidental and not disease causing.

        Maybe they could do the same thing that EA suggests - just keep trying random data at the end until it all works.

    • It should. The next step, I think, would be to sequence more people with AML M1 because the genetics heterogeneous. Then we can compare genes to normal controls and within the specific types to find the genes in common, if any, and maybe direct treatments against those genes/gene products.

    All the lab has to do now is patent the gene sequence and then sue mother nature for everything she's worth every time someone expresses this gene!

  • Ok, I'm going to lose major Karma for this.... but what the hell..

    This is not only the first cancer genome published, it is the first female genome as well.

    Wait, wait, wait.... you mean they're different?

    • I was thinking the exact same thing. I didn't realize that men and women have different genomes. According to this page [wellcome.ac.uk]

      "Surprisingly, a male genome is not the same as a female genome â" and it even appears that genomes may be engaged in a genetic 'tug of war' within a developing embryo."

      It continues saying

      "An example is the insulin-like growth factor system, which has a strong influence on the size of a baby. The logic is that the paternal genome works to maximise the growth of the offspring, to g

    I'm pretty sleepy but at first glance I thought the first whole Cancer Gnome sounded pretty scary!

    • So, is she hot?

      well they published her genome, so you can make your own and find out.
      The source code is a little buggy though.
