Genetically Modified Chickens Lay Eggs Containing Anti-Cancer Drug,Cancer Biotechnology

Genetically Modified Chickens That Lay Anti-Cancer Loaded Eggs



In the future, doctors might prescribe these “Special Eggs” to patients suffering from Cancer & arthritis. Researchers at Roslin Institute, University of Edinburgh have genetically modified chicken to lay eggs loaded with drugs for treating some types of cancers & arthritis. It can prove to be a highly cost-effective method of producing cancer drugs, maybe 100 times cheaper.

Currently, Eggs are already used as a source to cultivate viruses for use in vaccines. Animals such as goats have also been genetically modified earlier to enhance protein containing milk production.

Chicken/Egg Problem



The eggs laid by a group of “pampered” hens in the U.K. contain something special in their whites.
After researchers from the University of Edinburgh spliced a human gene into the chickens’ DNA, the animals began laying eggs boasting a significant amount of two proteins used to treat diseases including cancer in humans — and the process, they say, is far cheaper than current methods of protein production.
“Production from chickens can cost anywhere from 10 to 100 times less than the factories,” researcher Lissa Herron told the BBC. “So hopefully we’ll be looking at at least 10 times lower overall manufacturing cost.”

Protein Packed

The human body naturally produces the proteins found in the new hen eggs — IFNalpha2a and macrophage-CSF, if you’re wondering — and they each play an important role in the immune system. Drugs containing both proteins are widely used by doctors to treat cancers and other diseases, but producing the proteins in the lab is difficult and expensive.
For their study, published in the journal BMC Biotechnology, the Edinburgh researchers inserted the gene that produces the proteins in humans into the part of the chickens’ DNA that handles the production of the white in its eggs. When they tested the hens’ eggs, they found that just three eggs contained a dose-worth of the proteins.
The genetically modified chickens, which live “pampered” lives in large pens, are none the wiser either, according to Herron. “As far as the chicken knows, it’s just laying a normal egg,” she told the BBC. “It doesn’t affect its health in any way, it’s just chugging away, laying eggs as normal.”

Multiple Baskets

Though their research yielded promising results, the team believes it’d take between 10 and 20 years before regulatory agencies would approve for human use any drugs developed from their genetically modified chickens. But the proteins in the animals’ eggs could serve a purpose in the interim.
“We are not yet producing medicines for people,” researcher Helen Sang told the BBC, “but this study shows that chickens are commercially viable for producing proteins suitable for drug discovery studies and other applications in biotechnology.”

Beer production

Brewing  is the production of  beer  by steeping  a  starch  source (commonly cereal  grains, the most popular of which is  barley ) [1]  in water and  fermenting  the resulting sweet liquid with  yeast . It may be done in a  brewery  by a commercial brewer, at home by a  homebrewer , or by a variety of traditional methods such as communally by the  indigenous peoples in Brazil  when making  cauim . [2]  Brewing has taken place since around the 6th millennium BC, and archaeological evidence suggests that emerging civilizations including  ancient Egypt [3] and  Mesopotamia  brewed beer. [4]  Since the nineteenth century the  brewing industry  has been part of most western economies. The basic ingredients of beer are water and a  fermentable  starch source such as  malted barley . Most beer is fermented with a  brewer's yeast  and fl...

When to see a doctor If you can't ๐Ÿ˜ดsleep In over night or traveld sleep.you may be suffring from inosomia know more about inosomia

What is Insomnia? If you can't sleep, you may be wondering if you have insomnia. Insomnia is a complicated condition. What is the definition of insomnia? According to guidelines from a physician group,  insomnia  is difficulty falling asleep or staying asleep, even when a person has the chance to do so. People with insomnia can feel dissatisfied with their sleep and usually experience one or more of the following symptoms : fatigue, low energy, difficulty concentrating, mood disturbances, and decreased performance in work or at school. How long does insomnia last? Insomnia may be characterized based on its duration.  Acute insomnia  is brief and often happens because of life circumstances (for example, when you can't fall asleep the night before an exam, or after receiving stressful or bad news). Many people may have experienced this type of passing sleep disruption, and it tends to resolve without any treatment. Chronic insomnia  is d...

Ethanol fermentation

Ethanol fermentation Read in another language Watch this page Edit In ethanol fermentation, (1) one glucose molecule breaks down into two pyruvates. The energy from this exothermic reaction is used to bind the inorganic phosphates to ADP and convert NAD+ to NADH. (2) The two pyruvates are then broken down into two acetaldehydes and give off two CO2 as a by-product. (3) The two acetaldehydes are then converted to two ethanol by using the H- ions from NADH, converting NADH back intoNAD+.                     Ethanol fermentation , also called alcoholic fermentation , is a   biological process   which converts   sugars   such as glucose ,   fructose , and   sucrose   into cellular energy , producing   ethanol   and carbon dioxide   as by-products. Because yeasts   perform this conversion in the absence of   oxygen , alcoholic fermentation   is conside...
