GM Yeast Produces Human Protein

Posted by michael on from the sourdough dept.

Makarand writes "A team of US scientists has been able to genetically modify yeast to produce fully human protein. Human protein chains have specific groups of sugars attached which determine how these proteins will fold and function. The process of attaching these sugars to the protein, called glycoslylation, which has always evaded researchers can now be been carried out in the labaratory using genetically modified yeast. The team removed the yeast's genes that added sugars to the protein in a 'non-human' way and added five new genes to the yeast to add the sugars required by the human protein to fold and function."

    A lot of people seem to think that anything genetically engineered is automatically bad. Obviously we need to be careful when it comes to ecosystems, etc., but the DNA-huggers don't see many of the wonderful things that can come through genetic engineering. The advance described in this article is really amazing.

    Any treatments that involve human proteins will be benefited by this technique, including antibodies and hormones, as mentioned in the article.

    Science can't solve all problems, but it's always exciting to see advances like this which will make a big difference in real people's lives.

    Well, it will largely depend on what those GM yeasts "eat" and how many usefull/useless/harmless/harmfull "byproducts" these GM yeasts make...
    Think about it: a small "bulge" of half a pound yeast culture, eat it once (warning: various antibiotics will kill them, so you'll have to make a "refill")... then eat all sorts of cheap stuff (raw cereals, treebarks, grass or even paper) and never be hungry again: the GM yeast cultures in your digestive tract will take those "useless" (for normal humans) balasts and turn them into a nutritious meal...

      Actually, antibiotics kill bacteria, not yeast. There's a balance within the body of microorganisms, including bacteria and yeast, that keep each other's growth in check.

      So what you could see while taking antibiotics would be a possible overgrowth of yeast within the body. Not so much fun.

      This is a fantastic development, though, and a huge step ahead for new medical therapies.

      While it's an interesting idea, it reminds me with the nutrient pill idea. You know, that in the future there will be this pill and it will be all you need to survive.
      The main problem with this is not just the technology, it's that so many people actually enjoy eating a good meal. It's like a cure for sex. Certain people might think it's a great idea, but most people don't really want it.
      I saw a similar thing about high tech nano fiber clothes where the author said, isn't this great, you could wear the same outfit all year long. I looked over at my wife browsing her fashion magazines and thought, this was clearly written by a man.
      So many of these solutions for the future are answers to problems that aren't really problems across the board.
      But I wonder if these yeast cells can be made to produce growth hormone and human fetal serum. That would be intriguing as all hell.
