Protein plays a very important role in the human body. Protein is most commonly known for building muscle. While there are many types of proteins in the body that have their own specific responsibilities. Myostatin or growth differentiation factor 8, GDF8, is just another protein in the human body, its responsibility however is to inhibit the growth and definition of muscle. In a very rare genetic mutation called myostatin-related muscle hypertrophy, a person is born with low myostatin causing little fat and strong muscles. Myostatin was discovered in 1997 by researchers and scientists. They found this protein in many animals the most common tested were mice and the Belgian blue cattle. It was not known to be in humans until the birth of a German baby. There was a baby born in Germany in 1999 with this myostatin deficiency. He was born with low levels of myostatin causing his muscles to be twice as strong as the other kids around him. Another exam ple was a child born in Michigan, Liam Hoekstra. He was born with normal levels of myostatin but they were not reacting properly. With the myostatin not reacting like it should, it caused him to have super strength. Liam was able to stand on day two with support and could do a pull up at 8 months. With these recent findings it means so much for the future in the development for treatments of muscle wasting diseases. Muscular dystrophy is the weakening and loss of muscle tissue, this disease effects nearly 100,000 people every year. With no known cures for the disease there could be. If scientists can recreate a drug that has the same effects as the rare myostatin-related muscle hypertrophy then we might have the first cure for muscular dystrophy. A drug of this kind would be able to slow down the loss of muscle tissue and possibly even reverse it and grow the muscle tissue back. Although if they can figure out a way to take out any horrible side effects then there is room for abuse of the drug. If a drug like this is invented athletes would be all over it trying to make it a performance enhancer. Some companies have already started. Biotest, Cytodyne, and Pinnacle are three companies all in the sport supplements field, already working and spending a lot of time and money to create a myostatin neutralizer. This find in genetic mutation can have its ups and downs, but hopefully the pros will out way the cons.
