This Is How Scientists Have Bypassed The Aging Process

Over the years, your body loses the ability to prevent diseases. The aging process is a key factor for this condition. However, is it always so?

A team of researchers from UCLA, led by David Walker, has identified a gene that can bypass the aging process. They found a way to affect one part of the body, which will cause a reaction on the gene on a different part of the body. The results of this research were published in Cell Reports.

AMP – activated protein kinase (AMPK) is an enzyme in eukaryotic organisms that help in regulating cellular energy levels. Low energy activates AMPK, which synthesizes ATP and by fatty acids increases the level of glucose. Fruit flies that own this gene live 30% longer. This gene extends their lifespan by an average of 6 to 8 weeks. It improves the quality of their life also. The Walker’s team discovered that fruit flies that live longer, were healthier.

If similar effect occurred in humans, it would mean slowing down the aging process and extending the lifespan for 24 years.

Delay of the Aging Process.

This finding is the basis for further intervention on the delay of the aging process and beginning of many human diseases, such as Parkinson’s disease, Alzheimer’s disease, cancer, stroke, diabetes, cardiovascular diseases and others. More researches are needed to prove this, but the goal is realistic – to promote healthy aging in humans.

Microautophagy is the key to this process. For example, if cells in the brain have damaged or old pieces and those cells stay there, they can cause Alzheimer’s or Parkinson’s disease. Clearing this mess avoids the negative effects of the aging process in other parts of the body.

Previous research has shown that AMPK can activate autophagy and this latest research shows that it can be strengthened. In fact, they found that when this gene is activated in the nervous system of fruit flies, there is an increase in autophagy in the stomach. Furthermore, activation of AMPK in the intestines causes autophagy in the brain.

Aging Process - AutophagyFruit flies are the first great step for genetic experiments, because they own 75% of the genes that cause human diseases. Although researchers during the survey studied more than 100,000 fruit flies, the real result will come when they experiment on animals whose physiology is closer to human.

Indeed, the connection between AMPK and the early signs of Alzheimer’s disease were described in the study published on April 10, 2013. Therefore, we should wait for a while to see how this approach will work in complex organisms.
