A game-changing study that has examined 15,000 tissue samples from 348 mammal species has revealed a potential key to unlocking the mysteries of living longer. The research goes deep into the world of epigenetics and sheds light on the prospect of extending lifespans, not just for animals, but for humans as well.
A team led Steve Horvath at Altos Labs in Cambridge, UK spent seven years focused on the presence of epigenetic markers, specifically CpG methylation, within the genome. These markers, like biological labels, dictate gene activity without altering the underlying genetic sequence.
The study suggests the possibility of predicting maximum lifespan, gestation time, and age at sexual maturity in diverse mammalian species based on these epigenetic markers. This predictive power has massive implications for understanding species longevity.
However, this method encounters limitations, especially in predicting the maximum lifespan for humans. It also highlights the potential natural advantage of females over males when it comes to longevity, but it fails to take into account lifestyle factors like caloric restriction or body weight.
While the study is a huge leap forward in understanding species longevity, it fails to discern variations in individual lifespans within the same species. It also underscores the unique nature of epigenetic signatures as intrinsic determinants of maximum lifespan.
In essence, the groundbreaking study offers a glimpse into the potential link between epigenetic markers and species longevity. However, it also highlights the need for further exploration, particularly in understanding individual variations within species and the causal relationship between these markers and lifespan changes.
