Can Antidiabetic Medications Affect Telomere Length in Patients with Type 2 Diabetes? A Mini-Review

Abstract:
The fight against aging is an eternal pursuit of humankind. The aging rate of patients with type 2 diabetes mellitus (T2DM) is higher than that of healthy individuals. Reducing the aging rate of patients with T2DM and extending their life expectancy are challenges that endocrinologists are eager to overcome. Many studies have shown that antidiabetic medications have potent anti-aging potential. Telomeres are repetitive DNA sequences located at the ends of chromosomes, and telomere shortening is a hallmark of aging. This review summarizes clinical trials that have explored the association between antidiabetic medications and telomere length (TL) in patients with T2DM and explore the mystery of delaying aging in patients with T2DM from the perspective of telomeres. Various antidiabetic medications may have different effects on TL in patients with T2DM. Metformin and sitagliptin may protect telomeres in patients with T2DM, while exogenous insulin may promote telomere shortening in patients with T2DM. The effect of acarbose and glyburide on TL in patients with T2DM is still uncertain due to the absence of evidence from longitudinal studies.
Insights
Certain antidiabetic drugs may slow aging in type 2 diabetes mellitus (T2DM) patients by affecting telomere length. Metformin and sitagliptin show protective effects, while insulin may accelerate aging.
Area of Science:
- Endocrinology
- Gerontology
- Molecular Biology
Background:
- Aging is accelerated in type 2 diabetes mellitus (T2DM) patients.
- Telomere shortening is a key indicator of biological aging.
- Antidiabetic medications are being investigated for their anti-aging properties.
Purpose of the Study:
- To review clinical trials on the association between antidiabetic drugs and telomere length (TL) in T2DM patients.
- To explore how antidiabetic medications influence aging through telomere dynamics.
Main Methods:
- Systematic review of clinical trials.
- Analysis of studies investigating telomere length in T2DM patients treated with various antidiabetic medications.
Main Results:
- Metformin and sitagliptin may preserve telomere length in T2DM patients.
- Exogenous insulin use appears to be associated with accelerated telomere shortening.
- Evidence regarding acarbose and glyburide's effect on TL in T2DM is inconclusive due to limited longitudinal data.
Conclusions:
- Antidiabetic medications differentially impact telomere length in T2DM.
- Metformin and sitagliptin show potential for anti-aging effects by protecting telomeres.
- Further research is needed to clarify the role of other antidiabetic agents in T2DM aging.
