Triggering muscle development — a therapeutic cure for muscle wastage?

Muscle tissueScientists in the UK and Denmark have shown that if elderly men were given growth hormone and exercised their legs showed an appreciable muscle mass increase. Dr. Geoff Goldspink (Royal Free and University College Medical School, UK) says: “This raises the question: Can age-related loss of muscle strength and increased fragility be ameliorated by the therapeutic application of mechano growth factor (MGF)?”. There is hope that MGF can also help sufferers of diseases such as muscular dystrophy, ALS, renal disease or cancer, for whom intensive exercise is not an option. It may even prove useful to ameliorate muscle loss resulting from long periods in zero-gravity conditions during space travel. Dr. Mark Lewis (University College London, UK) will present their latest results on how MGF exerts its effects during his talk at the Society of Experimental Biology Annual Meeting in Glasgow on Wednesday 1st July 2009.
