Could a new discovery hold the key to controlling diabetes?

Many people are surprised to find out that the duck-billed platypus is venomous. But they may be more shocked to learn that this venom may hold the key that unlocks new treatments for Type 2 diabetes in humans, according to a new study.

Australian researchers found that the same hormone that regulates the animal’s blood sugar is produced in their venom. This hormone, glucagon-like peptide-1 (GLP-1), is normally secreted in the gut of both people and animals and causes the body to release insulin and lower blood sugar levels.

In people, the GLP-1 hormone typically breaks down within minutes. In people with type 2 diabetes, the short life span of the hormone isn’t enough to maintain the right insulin-blood sugar balance.

But researchers discovered that platypuses and their monotreme (egg-laying mammals) Australian cousins, the spiny ant eater (echidna), have evolved changes in GLP-1 that resist this rapid deterioration. This stability makes the platypus-version of the hormone a possible starting point for developing new medications that could help diabetics.

“Obviously this is very preliminary research, but it certainly points in a promising direction for people who have diabetes,” says Dr. Varsha Bhan, an internal medicine physician on staff at Advocate South Suburban Hospital in Hazel Crest, Ill. “GLP-1 plays a significant role in insulin release and regulation, so any advances in that area could make a big difference.”

The Centers for Disease Control and Prevention reports that 29.1 million people in the U.S. have diabetes and more than 8 million are undiagnosed. According to Dr. Bhan, people develop diabetes because their pancreas doesn’t produce enough insulin or it doesn’t recognize the insulin the body makes.

“For many people, diabetes can be prevented or managed through a sensible diet and regular exercise,” she says. “But any and all help is welcome as we all work to minimize the effects of this potentially very dangerous chronic disease.”

  1. Interesting developments but disappointed that you refer to people with diabetes as “diabetics”. “In alignment with the American Diabetes Association’s (ADA’s) position that diabetes does not define people, the word “diabetic” will no longer be used when referring to individuals with diabetes in the “Standards of Medical Care in Diabetes.” The ADA will continue to use the term “diabetic” as an adjective for complications related to diabetes (e.g., diabetic retinopathy).”

  2. Thank you very much for the clarification. Absolutely no disrespect was intended. I was not aware of the ADA’s position and language recommendation. But, I am actively working on my “people first” language and this should have come into play in this instance. I have forwarded your note to our editors so that they may be able to use this information to educate other authors about this important point. I appreciate you taking the time to comment.

  3. I don’t feel the answer should come at the expense of any animal.

  4. I would be more interested in a study showing the relationship between the introduction of both “fortified whole grains” and the current love affair in GMO grains n the increase of type 2 diabetes in the population as a whole.

  5. How is it that is venom is a new found key to control diabetes, and not one to cure it? It seems that making a new medicine is always the goal in these new discoveries, but finding a cure should be the objective.
