Gilas Aid Research into Diabetes

The Gila lizard is another creature assisting the cause of human medicine.
The Gila hails from Arizona, but are popular zoo exhibits, being spectacularly eye-catching with their:

  • red and black or
  • yellow and black
pigmentation. Glasgow Zoopark is one of the places to breed them regularly in Europe. The Gila's venom contains the compound "Exendin" which is being turned into a new drug to fight Type 2 diabetes. Type 2 diabetes is suffered by approximately 1.2 million people in Britain.

Exendin is similar to a natural hormone called GLP1 and has the power to control the secretion of the body's own insulin. It also influences the speed the stomach empties, and regulates appetite.

Doctors hope it will reduce the death rate from the complications of diabetes, which include strokes and heart attacks.
