GM Yeast Produces Human Protein

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.

      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.

    Fact: *BSD is dying

    It is common knowledge that *BSD is dying, that ever hapless *BSD is mired in an irrecoverable and mortifying tangle of fatal trouble. It is perhaps anybody's guess as to which *BSD is the worst off of an admittedly suffering *BSD community. The numbers continue to decline for *BSD but FreeBSD may be hurting the most. Look at the numbers. The loss of user base for FreeBSD continues in a head spinning downward spiral.

    OpenBSD leader Theo states that there are 7000 users of OpenBSD. How many users of BSD are there? Let's see. The number of OpenBSD versus NetBSD posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 NetBSD users. BSD/OS posts on Usenet are about half of the volume of NetBSD posts. Therefore there are about 700 users of BSD/OS. A recent article put FreeBSD at about 80 percent of the *BSD market. Therefore there are (7000+1400+700)*4 = 36400 FreeBSD users. This is consistent with the number of FreeBSD Usenet posts.

    Due to the troubles of Walnut Creek, abysmal sales and so on, FreeBSD went out of business and was taken over by BSDI who sell another troubled OS. Now BSDI is also dead, its corpse turned over to yet another charnel house.

    All major marketing surveys show that *BSD has steadily declined in market share. *BSD is extremely sick and its long term survival prospects are very dim. If *BSD is to survive at all it will be among hobbyist dilettante dabblers. In truth, for all practical purposes *BSD is already dead. It is a dead man walking.
