PS: I Remember that had previously written about Yamanaka factors. Rapamycin is a mTOR inhibitor. It was isolated in 1972 from a bacterium found on Easter Island, aka Rapa Nui – hence the name. For many years it was an obscure transplant drug but in the early 2000s was found to significantly extend the lifespan of worms, yeast, flies and mice. It has been widely tested in animals.
The mTOR signaling pathway is also associated with cancer, arthritis, insulin resistance, osteoporosis, and other diseases. Also mTOR signaling pathway is a hot target in anti-tumor therapy research.
