Metformin is a drug commonly used to treat type 2 diabetes. But new research published in the Proceedings of the National Academy of Sciences (PNAS) finds the medication may also slow the aging process and increase lifespan.
Metformin belongs to a class of drugs known as biguanides. dieu tri dau nua dau For patients with type 2 diabetes, it helps control blood sugar by reducing the amount of glucose absorbed from food and the levels of glucose produced by the liver. It also increases the body's natural response to insulin.
But studies have suggested that the health benefits of metformin may reach further than type 2 diabetes. In 2010, Medical News Today reported on two studies that suggested metformin may protect against lung cancer in smokers. A 2012 study also found that the drug may show promise in treating patients with pancreatic cancer.
Now, a research team led by Wouter De Haes of the Katholieke Universiteit Leuven (KU Leuven) in Belgium finds that metformin may be useful for halting the aging process.
Testing metformin in roundworms
To reach their findings, the team conducted a series of experiments in the roundworm Caenorhabditis elegans - a model they say is ideal for studying the aging process as it only has a 3-week lifespan.
The team found that metformin increased the number of toxic molecules released in the worms' cells, which they were surprised to find boosted their long-term strength and longevity.
Roundworm model for metformin
On testing metformin in the roundworm C. elegans, the researchers found the worms showed no wrinkling, aged slower and stayed healthier for longer.

"As they age, the worms get smaller, wrinkle up and become less mobile. But worms treated with metformin show very limited size loss and no wrinkling. They not only age slower, but they also stay healthier longer," says Haes.
But how does metformin work? The team explains that our body's cells get their energy from mitochondria - the "powerhouses" in each cell that trigger small electric currents. coenzyme q10 This process can generate highly reactive oxygen molecules.
These molecules can be harmful to the body. They can damage proteins and DNA and interfere with normal cell functioning. But the tea
