The secrets of a key gene that helps us to live longer and fight disease have been unlocked by University of Birmingham researchers. They works to develop a drug based on the gene, which makes it a real possibility for cutting down the ageing process of the body.

Dr Robin May who led the research says that there is a definite potential to develop drugs slowing down the ageing process, though stopping ageing may not happen.

The higher levels of the gene called DAF-16, is directly linked with the longer life. It is strongly involved in determining ageing and average lifespan of laboratory worms. This genes also have effects on other traits including immunity. If the gene is more, the possibility to live longer will be high. Exposing the worms to a short burst of higher temperature, a quick bit of stress, increased the activity of this gene.

Scientists say that their experiment gave the idea that some moderate level of stress or challenge will be sufficient for us to live longer.

The study has been published in the journal Plus One.
