Forscher schlagen einen neuen Rahmen zur Verzögerung der Seneszenz vor, indem sie mithilfe von CRISPR eine unsterbliche „Hydra-ähnliche“ Genexpression in komplexe alternde Organismen einführen.

The freshwater organism Hydra is famous for its biological immortality, it continuously undergoes stem cell renewal and shows virtually zero signs of aging over time.

Conversely, rotifers are microscopic multicellular creatures that experience rapid, predictable biological decline.

A new study published in Aging-US presents a testable genetic roadmap to close this gap by introducing Hydra-like gene expression patterns into rotifers using CRISPR gene editing.
​Rather than attempting a full-scale overhaul, the framework isolates highly conserved molecular pathways, specifically focusing on the FoxO transcription factor and essential stemness markers to enhance internal cellular maintenance, stress resistance, and proteostasis within adult cells.

This research provides a stepwise experimental template for translating negligible senescence from simple organisms into complex ones, acting as a crucial, low-risk stepping stone to prioritize pathways for future mammalian and human validation.

Vectoring is always going to be the issue in these cases. The „best“ way I can think of of dealing with that would be to just try and insert a whole plasmid that we can then vector at will. It’s a more difficult thing to do at the beginning, but then you are priming for the future AND you don’t run the risk of slicing something important. Basically a whole new chromosome.

Imagine when the billionaires forget about AI and start dumping their money into this to become immortal

I look forward to growing my third or fourth head as I reach 240 years old…
