The future cost of producing cancer drugs may have dropped in price with the laying of eggs from genetically-modified chickens.

Roslin Institute scientists have announced the successful creation of five generations of chickens that can lay eggs containing a specific protein needed to manufacture drugs used in the treatment of cancer. The Roslin Institute is the same research facility that cloned the Finn Dorset lamb named Dolly.

According to the BBC News report that states, "the work at Roslin shows it is now possible to use chickens as biofactories," more than one genetically-modified animal is being used as just such a factory for complex proteins needed to produce drugs.

It will be five-to-ten years before the drugs made from the protein of eggs from these genetically-modified chickens can be safely used, if clinical trials show favorable outcomes.

Remember Dolly the first successfully cloned sheep? In 1997, a scientist named Ian Wilmut stunned the world when he announced he had successfully cloned a sheep from an adult cell. With a new book, After Dolly, set for release on June 12, Wilmut is suggesting that we should seriously consider cloning babies to put an end to genetic disease. But Wilmut says he is not suggesting the practice of genetic enhancement to create designer babies. It certainly sounds like that is what he is saying when he suggests that parents, with the assistance of scientists, be allowed to combine the cloning of human embryos with genetic modification to eliminate hereditary disease. The process of creating designer babies is the same, the intent of purpose separated by a thin veil. Regardless of what he says he is or is not saying -- what he is describing is the eventuality of designer humans.

Wilmut states, "The use of genetic and reproductive technologies is not a step backward into darkness, but a step forward into the light." But in following Wilmut into his light, will our eventual fate be that of Icarus, who soared toward the sun on wax wings? I don't want to go all Luddite, but I am very uneasy about the ethics and where this all leads. And to take it to the next level, will there one day in the future be two races of humans? The genetically perfect designer human, and the genetically-imperfect unmodified human. How will it work? Who will decide? What do you think? 

In 2003, University of Idaho and Utah State University researchers cloned three mules. The success of the cloning came about by manipulating calcium levels. Calcium affects how quickly cells divide. The researchers are hoping that calcium levels and function might explain why horses and mules develop cancer at much lower rates than humans. Because of these cloning facts and findings, they base a possible hypothesis for discovering a key to cancer on the fact that calcium imbalances are indicators of human prostate cancer and diabetes. According to a news report aired on KBCI News in Boise, Idaho, no male horse or mule has ever been diagnosed with prostate cancer and melanoma does not metastasize in their bodies.

Two of the three healthy cloned mules, Idaho Star and Idaho Gem, are preparing to race in Winnemucca, Nevada at the Mule Races and Draft Horse Challenge. The cloned mules will gain worldwide attention next week when they become the first cloned mules to participate in a sporting competition. Perhaps one day, cloned mules will help win the race in a cure for cancer.
