Telomere Length and Type 2 Diabetes: What Researchers Observed
Another interesting November research article recently published deals with the shortening of telomeres as the missing link between aging and type 2 Diabetes (AGING, 2010, Vol 2 no 10:650). As stated before telomere shortening, either because there is no telomerase activity or by some other mechanism, have been documented to be associated to diseases of aging. In the present study a group of scientist led by Michael Ristow used mice to establish a link between Diabetes and telomere shortening. In their study, the group utilized mice that had their telomerase enzyme modified in such a way that it was inactivated. This resulted in telomere shortening and reduced replicative capacity of beta-cells (the pancreatic cells that produce insulin). The lack of insulin secretion and the increase of glucose intolerance can therefore be viewed as an aging-associated disorder and method of increasing telomerase activity could result in improvements in this disease.
Frequently Asked Questions About Telomeres and Type 2 Diabetes
Is there a link between telomeres and type 2 diabetes?
A study led by Michael Ristow (AGING, 2010) identified telomere shortening as a missing link between aging and type 2 diabetes in mice.
How did researchers establish the link?
The team inactivated the telomerase enzyme in mice, which resulted in telomere shortening and reduced replicative capacity of beta-cells — the pancreatic cells that produce insulin.
Why do beta-cells matter?
Beta-cells produce insulin. When their replicative capacity falls, insulin secretion drops and glucose intolerance rises — an aging-associated disorder.
Could increasing telomerase activity help?
The researchers note that methods of increasing telomerase activity could result in improvements in this disease, though the findings come from animal research.
Where can I learn about telomerase activation?
RevGenetics covers telomerase-activation science on this blog and carries authentic, independently verified TA-65.
