Suppressed Report Shows Cancer Link to GM Potatoes

Doc Ruby writes "After an 8-year-long court battle, Welsh activists have finally been allowed to released a Russian study showing an increased cancer risk linked to eating genetically modified potatoes. While the victory of the Welsh Greenpeace members in the courtroom would seem to vindicate the work of the Russian scientists that did the original research, there are still serious questions to be answered. The trials involved rats being fed several types of potatoes as feed. The rats who were fed GM potatoes suffered much more extensive damage to their organs than with any other type; just the same, serious questions remain about the validity of the findings. The Welsh group wants to use this information to stop the testing of GM crops in the UK, tests currently slated for the spring of this year."

This is done over several generations until no seeds are produced. Think Gregor Mendel and a Punnett square. It's the manipulation of pre-existing genetic information to achieve some desired end.

    Genetic Modification is inserting (or deleting) pieces from the genome (DNA) of a certain whatever. Introducing pieces of new genetic material is certainly different from what you're talking about.

    Someone needs to explain to the general populace that GM food is still just food. If the genetic changes are bad, and cause the food to produce something dangerous, or more of something dangerous, that's one thing (and we should be weary of that of course). But there's nothing inherently dangerous about genetic alterations. I'm tired of the belief that the GM somehow gets into the food and makes it evil, explanation unneccassary. It's like people being convinced that irradiated food is radioactive or something. Sigh.

    Breeding grapes until there is a variety that is seedless isone thing, taking DNA from a fish and splicing it into is another.
    Bunk. No GM foods contain any animal protein. If you're talking about just transplanting a minor gene, then so what? The same gene that's present in that fish is probably present in 20,000 other animal species, and at least a few dozen plant species. You're just trying to use word-play to induce frightening images of frankenplants in peoples minds. In reality, DNA modification is no different than selective breeding and cross breeding, it just works a hell of a lot faster.

    That was my point. What many of the people replying don't get is that selective breeding is genetic manipulation. What you're talking about is the same thing with a new technological twist, and there's no reason why you should be afraid of it simply because we're better at it.

    Genetic Modification is inserting (or deleting) pieces from the genome (DNA) of a certain whatever.

    Ok, no argument with your definition. In the past, that was done through selective breeding. Today we have more efficient methods to do the same thing quicker for more dramatic results. The end result is still the same. You get a breed with qualities that you want.

    Introducing pieces of new genetic material is certainly different from what you're talking about.

    In what way? When you manipulate "pre-existing genetic information", you can do that because different plants of the same species have different qualities. They have different qualities because of random mutations and gene crossover combinations. Instead of waiting for random mutations, we add designed mutations to the mix. Usually purposefully damaging a gene that is responsible for undesired qualities. It's the same thing but now we have technology, so it's dangerous!

    I don't dismiss the fact that it's possible to end up with something that causes ill effects through genetic manipulation, but treat those problems in a case-by-case basis. My problem with the grandparent was his "you have to be stupid to eat GM foods" tirade. That's a ridiculous attitude with no merit whatsoever. Mostly we just end up with better foods because we added features we want and removed features we don't.

  31. Terminator gene useful by Lars512 · · Score: 5, Insightful

    Most of the GM foods being pushed have nothing to do with starving people - it's all about increasing corporate profits, as usual. The "terminator gene" was being pushed to prevent poor third-world farmers from saving their own seed after buying grain crops once.

    There's two sides to the terminator gene, as I understand it, one of which you're overlooking. Suppose you engineer a crop which grows extremely well, much better than in its original form. This crop might spread wildly, and become a form of a weed, overcoming native plants and even other useful crops. The terminator gene is useful here because it prevents the crop from spreading into the wild. In this way it's a safeguard.

    Suppose there is some series of studies confirming that a particular crop is statistically more correlated with the occurrence of some medical problem in humans who eat it. If that crop has already spread in the wild, and perhaps merged with non GM crops, then we'll still be eating it whether we like it or not. We need safeguards like the terminator gene.

    Also, using it doesn't mean choosing the new business models it allows. They could sell seed to the same farmers at close to cost price for repeat customers, making it closer to the existing business models.

    The new leaf potato which the fuss was put in production 8 years ago, eaten by many people, was found not to be profitable and is now defunct.

    I think the point is that this is FUD - no-one knows what it means, but it scares people. If you look at Microsoft press releases about Linux you might spot a similar pattern.

    Raising questions won't change the fact that such foods do have very harmful effects. Would any amount of evidence change your opinion that these foods have harmful effects, or is it more of a faith thing?

From the independant article "Greenpeace said the Russian trials were also badly flawed. Half of the rats in the trial died, and results were taken from those that survived, in breach of normal scientific practice". Basically this russian group abused/neglected a large group of rats, and gathered data attempting to link their unfortunate conditions to a pretty charged topic. The worst thing about these kinds of reports and pseudoscience is that it takes away from serious studies to determine the health benefits of GM, or in fact any foods.

    If you want to know more about GM food, go ahead and read this book, seriously. It is an eye-opener to me, as someone who knows next to nothing about farming and thinks there might be some good reasons for NGOs to oppose GM food so vehemently.

    A few juicy points from the book (not in the order as they appear in the book, just the order it came out from my memory), though I knows too little to judge if their validity:
    • In the book it mentioned one similar experiment with potatoes and mice (not sure if this is the same one), however, the experiment is so poorly controlled (e.g. the GM potato contains less vital nutrients compared to the "normal" potatoes) that the mice are more likely damaged through malnutrition than any effect of GM food. Other experiments that accounts for all the intake value of different nutrients showed no harmful effects for GM food.
    • Agriculture in its current form (with pesticides, fertilizers, etc) is already the most destruction thing human does routinely to nature. Any additional "damage" to the environment due to planting GM crops won't make much a difference anyway.
    • Corn farmers already have to buy seed every year from dealers, no terminator gene needed! Why? Because modern corn are usually hybrid breeds that give great yield but do not generate viable seeds. But you don't see NGOs screaming at seed dealers. This shows that farmer don't mind buying seed constantly as long as the yield difference is worth the price.
    • People has been making genetically new variants of plants for centuries already (i.e. through selective breeding). Needless to say, none of these new variants are subjected to as much scrutiny as GM foods has gone through (yet some still think them "unsafe").
    • Before GM, there were already other means (e.g. soaking in chemicals, radiation, etc) to cause genetic mutation in plants, which can also result in new variants of plants. These crops, however, are not called "GM" and can be sold with as much testing as variants obtained through breeding (i.e. no testing at all).
    • In some cases, the use of GM crops can and do reduce the use of pesticides, so it is not all bad.
    • Furthermore, one of the famous GM linked pesticide (Roundup), has the advantage of naturally decaying in matter of weeks. Thus using Roundup linked crop with Roundup do leave less harmful chemicals around in the environment.

    It's rare to find so much misinformation at Slashdot, and that's saying something.

    Humans and chimpanzee DNA are very similar, there are apparently about 40 million differences (out of about 3 billion positions) between chimp and human DNA; in protein coding regions, the number of differences is much smaller.

    Humans and mice, on the other hand are far more evolutionarily distant (80 million years since the last common ancestor, compared with 5 million, or less for chimps). In protein coding regions, mouse and human DNA sequences are about 80% identical, on average, but outside protein coding regions, the level of sequence similarity is no higher than would be expected by chance. (This large difference was one of the reasons the mouse genome was sequenced after the human genome - sequences that were more similar than chance were expected to have a function.)

    While plants and animals (and bacteria) share a large number of proteins that do similar things, their DNA sequences do not share any significant similarity except in protein coding regions for very highly conserved proteins.

    What all of this has to do with unpublished Russian studies on genetically modified plants, I cannot imagine.
