A team of scientists at the University of Liverpool has found a new method to detect proteins associated with longevity. This study has all in it to enlighten mankind on the major puzzle of biology as to why some animals live longer than others?
More than 30 mammalian species’ genomes were searched to identify the proteins connected with longevity. It was found that in longer living species, an important protein evolves and changes in a non-random way which responds to DNA damage.
A similar pattern was identified in proteins associated with metabolism and cholesterol. They also found that proteins associated with the degradation of damaged proteins were linked with the evolution of longevity in mammals.
The research by Dr. Joao Pedro Magalhaes and Yang Li could be seen as useful in anti-ageing interventions. According to Dr. Magalhaes, the proteins they detected were found changing in a particular pattern.
That means evolution of these proteins was not accidental. It is designed to cope with the biological processes impacted by ageing such as DNA damage. These proteins help in body repair and keep ageing process at bay.
If scientists prove themselves successful in identifying the proteins that allow some species to live longer than others, it could help improve human health and slowdown the ageing process. The research findings have been published in the American Aging Association‘s journal AGE.
