Peptide Hormones

• EPO is a hormone naturally produced by the kidney

• Its major function is to promote the development of red blood cells and to initiate the production of haemoglobin (the molecule within red cells that transports oxygen)

• EPO has been much misused as a performance-enhancing drug in endurance athletes including some cyclists (in the Tour de France), long-distance runners, speed skaters, and Nordic (cross-country) skiers

• This can be dangerous as it leads to dehydration which can cause strokes and heart attacks

Erythropoietin (EPO)
