most feared by Olympic

Muscle atrophy is a muscle disorder problem that is being solved by gene therapy right now. by using an adeno-associated virus (AAV) scientists have modified it with a gene that could produce IGF-I proteins. Once the DNA that could produce the IGF-I protein is integrated into the muscle’s DNA, the gene would allow skeletal muscles to regenerate and strengthen, thus providing muscles with more endurance and power. This process have been proven very effective with mice and cows; in mice testing, the over all muscles grew 15-30% more than before, showing a significant change in muscle size.
This can help the elderly especially, could be benefited from this type of gene therapy; their muscles have been weakening with age, thus if we could introduce the DNA that could create IGF-I proteins, think of how much better we could make their lives?
this is also one of the most feared researches by Olympic supporters.
