Scientists aren't stopping in their attempts to try and unlock the secrets of aging so we can live healthier lives for longer.
so we can live healthier lives for longer. Now research into 'jumping genes' has revealed a crucial role they play in the way our bodies get older.If DNA is like a biological blueprint for our bodies, then TEs are bits of this blueprint that can move around within the genome – it's a natural process in humans and other animals, but if it's not carefully controlled, it can cause problems.
But until now, it hasn't been clear whether cellular aging influenced TE activity, or whether TE activity influenced cellular aging. With this-adenine methylation within TE segments – a type of shift in gene activity which increases TE activity – as the worms aged, with the implication being that TEs get busier as we get older.
These are all fascinating findings, and further down the line, we may be able to modify and influence this TE behavior so cellsas they otherwise might. We probably won't ever become immortal jellyfish, but we might be able to ensure that our elderly populations have fewer problems with diseases and ailments.
"This epigenetic modification may pave the way for a method to determine age from DNA, providing an accurate biological clock,"
