You can't squeeze blood from a turnip, but it might be possible to extract it from rice. Blood protein, at least. Genetically modified brown rice seeds can produce a cost-effective and easily stored supply of human serum albumin, researchers in China report.
HSA is important for treatment of a wide array of maladies, including severe burns, liver cirrhosis and hemorrhagic shock, and it's a key ingredient in drug and vaccine tests. But its primary source is donated human plasma, so it is in short supply around the world — not least in China, which even saw reports of fake albumin for sale after a price spike four years ago. Hoping to come up with an artificial supply, previous researchers have attempted to draw human blood protein from potatoes, tobacco leaves and genetically engineered mouse milk. But grains would be more efficient, according to researchers led by Yang He and Daichang Yang at Wuhan University in China.
Rice will keep in storage for long periods, it's easy to grow and maintain, and it is also particularly good at accumulating DNA from other organisms, the researchers write in the Proceedings of the National Academy of Sciences.
To make the transgenic rice, the team introduced recombinant HSA protein promoters into brown rice plants using Agrobacterium. (Click here to read our prior coverage of how plant genetic modification works.) They wound up with 25 transgenic plants, nine of which were able to breed. They checked the plant seeds and confirmed the presence of the rice HSA, which they call Oryza sativa recombinant HSA or OsrHSA. Compared to regular rice, the transgenic seeds were nearly transparent, as seen below.
Then the team figured out how to purify the protein, yielding about 2.75 grams per 2.2 pounds of rice. The team conducted several assays to determine the molecular mass and amino acid sequence of their transgenic protein, ensuring it has the same structure as the plasma-derived HSA. Then they tested the protein on some rats with liver disease, and confirmed the transgenic protein improved their liver function.
Clinical use of HSA requires pretty hefty doses, so producing enough OsrHSA would require growing lots of transgenic rice, the researchers note. This raises several environmental safety questions, but the team notes that rice is largely a self-pollinating crop, and initial tests showed very little (less than 1 percent) transgenic gene transfer via pollination. But this would obviously need to be further studied.
"Our results suggest that a rice seed bioreactor produces cost-effective recombinant HSA that is safe and can help to satisfy an increasing worldwide demand for human serum albumin," the authors say.
I have to say it...
you are what you eat.
I would eat it....
dont forget that the mutations are positive too...
(or there would be no adaptation/evolution)
so what they did it in the lab? antibiotics are made in lab too...
It works the same way as music... i dont care about the genre if its WELL MADE!!!
bored? lets go mine the stars... ^^
I really like to know, what are the health risk or health benefits of eating this rice long term?
Also, why stop at blood. Why not make a muscle\meat type rice and get more protein in your diet as well?
Say, lets just make a rice human and... oh, nevermind.
LOL ^^ you well understood the principals of genetical engeneering ^^
the more the better ^^
bored? lets go mine the stars... ^^
Didn't making bio-fuels with corn dramatically raise prices of food everywhere?
Potential history repeat?
WOW I NOW MAKE a gazillion dollars an hour jerking off and reading popsci articles..
Fuck off jimmy and every other spammer here
Xalar- bio fuels didn't raise the gas prices...As demonstrated by greedy oil seekers recently in a news broadcast. "demand has gone down for gas, so because of this the price rises. thats how economics works"
This was repeated on each network. and many news articles...
Bio-fuels are not made all from corn, and can be made from any organic material. You can make it yourself. If laws permit you -.-
If supply far exceeds demand, as it has for a while. the price should fall.
Add in some speculations, a war or 2 or 3, maybe four. Even though the first thing we secured was an oil pipeline, these people raise the price.
Rice could make excellent bio fuel xD
Rice with stuff our body says it can use as blood. Awesome. If it's safe. We don't need more public experimentation =c
Why isn't there a digital guinea pig?
