The findings could lead to a new drug to control Type 2 Diabetes which now affects millions and the number continues to grow.

The drug is also being tested on 130 patients in a Phase 2 study in combination with metformin, a drug therapy for Type 2 Diabetes, and results are expected later this year. Any anti-ageing effects have yet to be established.
