Yeast reveals secrets to extending longevity
Yeast genes in cells and humans are controlled by certain gene sets and a study done in Concordia is the first to present experimental scientific evidence that generic mechanisms exist that control longevity. For the studies, yeast was exposed to lithocholic acid, which delayed the aging process and so they lived five times longer than normal, earning them the name, “yeast centenarians.”
Their mitochondria utilized more oxygen and produced more energy making them more resistant to oxidative damage.
Professor Vladimir Titorenko explains that lithocholic acid can be used to force evolutionary change for increased lifespan. The two commonly held beliefs about aging are - programmed vs non-programmed, where one believes that lifespan is genetically limited for an evolutionary purpose while the other believes such a mechanism wouldn't be able to exist.
According to Titorenko however, this finding proves the programmed belief true as active genetic mechanisms were found to control the yeast's lifespan.
Age reversal is of big interest these days, and this is a very positive finding, because it proves that there are pre-programmed genetic limits set in place, and that they can be altered using natural molecules to increase longevity. I see the potential in this, there are many studies showing how certain compounds can contribute to extending lifespan, but there's still work to be done. However, this provides a foundation, and a positive direction in achieving longer life expectancy in human.
I can see someday in the future, it will be normal for people to live several hundred years if not more once mankind masters human biology.
