Artificial Chromosome Inheritance

Posted by Hemos on from the passing-it-down-the-lhe-line dept.

Socramon writes "There's been a lot of discussion (and flaming) lately about genetic experimentation. For those who aren't sick of hearing about it already, there's an article on New Scientist about a Canadian company, Chromos, which has created an artificial chromosome that has (so far) been passed down through three generations of mice. The company's homepage, www.chromos.com is, unfortunately, "Under Construction"."

      It could be argued that people's ethical ideas usually boil down to their gut feeling; "Reason is, and should be, the slave of the passions," as Hume said. But it would be more useful to examine your gut feelings to determine a basis of your morality, and deduce from there. For instance, do you believe that the consequences determine the morality of an action, or are actions categorically right or wrong? How do you define, "good" and "bad"? Without making such evaluations, your ideas about particular issues will be ill-founded.

      In any case, since I don't understand where you're coming from, I suspect my presenting arguments might not do you much good. "I've been raised under the notion" suggests, perhaps, a religious upbringing... religions tend not to replace the answers to basic philosophical questions, but rather to give them interesting twists.

      Anyway, as regards cloning in particular: do you think identical twins are wrong? If so, what should be done about the scoundrels? If not, is it because they were unintentional, or is there another reason? Or are you simply worried about the effects of widespread cloning?

      For my part, I say, "cool beans", and look forward to raising myself just as soon as it becomes affordable. Whether cloning is a good practice for society at large I would evaluate based on the effects it turns out to have upon society and the gene pool. It should certainly be legal, IMHO, but then I'm a libertarian looney, and not wholly to be trusted. :-)

  54. Artificial chromosomes are not new by Alik · · Score: 2

    Biologists have been making bacterial artificial chromosomes, or BACs, for years. BACs were a key component of the Human Genome project. They're conceptually quite simple; you take any ordinary chromosome and yank out the regions that actually code for stuff.

    The new thing here is putting one in and having it stick around between generations. I suspect, although they don't say for sure, that this was done by breeding modified mice to modified mice, so that every newborn had two copies of the artificial chromosome. I say this because otherwise, with every cell division only one of the daughter cells would have the added chromosome. This means that in each mating, only three-fourths of the kids would have a copy; if you mate these offspring two more times, you're going to lose a significant number of your artificial chromosomes.

    The idea that one can insert genes into a "safe" spot instead of having them integrate into the main genome is a good one. However, I'd be a bit worried about just inserting a gene without any promoter/represser elements and then amplifying that gene's function simply by adding more copies. The nucleus is not going to like having a large number of extra chromosomes floating around.
    IMHO, if you really want to do gene therapy to affect the descendants, you want to cut out the existing gene copy and put the new gene in exactly the same place. (Yes, if you wanted to add a totally new gene, these chromosomes would be a good place for it. Personally, I would not accept a new gene anytime soon, because I don't have faith in humanity's ability to get any technology right on the first pass.)

(Such a thing is not unheard of; it happens in certain cancers, although it's usually not a whole chromosome being amplified.) On reparse, I think you're right; it's more a matter of them inserting extra copies. IMHO, that's not the right solution; you can't regulate that very well. I'd say it'd be a better idea to insert strong promoter elements along with the new genes if you wanted them to be hyperproductive. (That way, if the gene temporarily needs to be turned down, you can administer a compound which inhibits the activator protein (although that may have issues depending on what other genes share that promoter).)

  57. Not so grave as people may think by infinite8s · · Score: 2

    For people not sure what this means, here is a little background:

    Biologists have been using artificial chromosomes for years now, except that they have only been able to engineer them for less complex organisms such as bacteria and yeast. Artificial chromosomes are useful carriers for genes that produce proteins that are medically and academically useful without disrupting natural chromosomal function. Also, when cells reproduce they replicate the articifial chromosome along with all the natural chromosomes, so that it is transfered from generation to generation (of cells, or if the chromosome is inserted into the germline, then organism to organism).

    However, the major problem with using bacterial artificial chromosomes (BACs) and yeast artificial chromosomes (YACs) is that there are some proteins that bacteria and yeast can't successfully produce (since they are simpler organisms, they lack the proper cellular machinery to manufacture and correctly fold larger proteins). So basically, these researchers have just extended a usefull technique to mice. Now it is possible to manufacture a greater range of useful proteins. Getting the protein from the mouse is a little messier than getting is from bacteria or yeast, however :(

    The main reason this is cool is that the machinery to replicate a mouse chromosome is (obviously) more complicated (and the chromosome itself is bigger) than a bacteria or yeast, so constructing a chromosome that has only the necessary scaffolding to ensure that it is replicated is pretty difficult. Unfortunately for the average non-biologist lay person, this New Scientist article was a bit vague (and exagerated) in describing the potential of this technique. At the end, they mention using mouse artificial chromosomes that contain a protein that can help ease the symptoms of rheumatoid arthritis, and that if the system works in rats trials will could begin in people. However, the human trials they are talking about have to do with testing the manufactured protein in people, not injecting humans with artificial chromosomes. That will be a long time coming (however, the Human Genome Project will certainly speed the development of human artificial chromosomes).

This is unneccesary and makes inheritance from base objects hard to trace.
