Comment on Moderna’s mRNA cancer vaccine works even better than thought
xor@sh.itjust.works 5 months agotelomeres are cells’ biological clock… they get shorter with each division, and is the general cause of your body breaking down, round the 80’s.
telomerase and other chemicals can reset those telomeres, but also cause the body’s existing precancerous cells to go malignant. (telomeres also limit cancer cell growth, and creating telomerase is one of the mutations required for full on cancer)
so, if we can regrow cells telomeres without causing cancer… we have a youth serum.
but there’s already other telomerase gene therapy in development anyways…

This is the step where a heavy [citation needed] comes along. There are a lot of complex processes involved in aging, we have no idea if simply "make the telomeres longer!" is going to solve all of that. Frankly it seems unlikely that that's all there is to it.
Don't get me wrong, I'm an optimist when it comes to longevity research. I think aging is a problem that will eventually be solved. But there's not going to be just one "cure for aging", there's a lot of things that go wrong over time and we're probably going to have to find ways to fix each of them as they come along.

Right. You would have to look at alzheimers, osteoporosis, arthritis, liver failure, heart failure, gut microbe health, and a million other things that can go wrong in old age. It’s a tall claim to say “all this can be solved by telemerase”. In fact, having one thing claiming to solve a million different issues is a big red flag for quack medicine.

A good rule of thumb in medicine is “anything that does everything probably does nothing”.
