Scientists discover longevity genes. Here's how it can extend lifespan of humans

For generations, humans have tried to find the elixir which can extend their lives beyond their natural limit and deceive death.

Now, scientists have made a discovery of a gene which has brought humanity very close to this impossible target of achieving longevity.

The gene has been found to possess the capability of promoting cellular repair and reducing the effects of ageing. This discovery has taken the scientific community close to finding methods for extending not just long but healthy lives.

Scientists are now understanding the mechanisms behind this particular longevity gene to find new strategies which can bring significant change in human ageing and lifespan.

The study was carried out by theUniversity of Rochester's team of scientists which comprised Doris Johns Cherry Professor of Biology and Medicine Vera Gorbunova and Professor of Biology Andrei Seluanov.

The Rochester researchers made the dramatic discovery after making a stunning observation of the naked mole rats.

Scientists found that these critters have long lifespans and are able to resist age-related diseases.These rodents are able to survive for nearly 41 years, which is almost a decade longer in comparison to the lives of rodents of their size.

What can this longevity gene do in the human body?

In the experiments carried out by the researchers, this specific gene was transferred into the bodies of mice.

This gene produces high molecular weighthyaluronic acid or HMW-HA which led to significant improvement inthe health of the mice and also increased their lifespan by around 4.4 per cent.

HMW-HA is a sort of mechanism which has a stunning effect on ageing and diseases.

HMW-HA is ten times more in the naked mole rats in comparison to the mice and humans. When the scientists removed it from the naked mole rat cells, the cells had more chances of forming tumours.

HMW-HA has the ability to fend off cancer. It was observed that the modified mice were able to protect themselves from spontaneous tumours as well as chemically induced skin cancer.

It was also noted that they suffered less inflammation, which is a sign of ageing, and had a healthier gut.

This discovery has now brought humans to the threshold of improving lifespan and healthwhile reducing inflammation-related diseases in them.
