We all want to live longer and thanks to medical technologies our life expectancies have dramatically increased. Which would be handy if we could actually enjoy the extra years. Unfortunately a study of long-lived mutant C. elegans by scientists shows that the genetically altered worms spend a greater portion of their life in a frail state and exhibit less activity as they age than typical nematodes. These findings suggest that genes that increase longevity may not significantly increase healthy lifespan and point to the need to measure health as part of aging studies going forward.
The fountain of youth might be just right around the corner, I know here at the labs we’ve reported several different ways to get to that fabled place, but now we have one more. New research shows that seniors received a significant boost to their immune systems when given a drug that targets a genetic signaling pathway linked to aging and immune function.
Want to live longer and healthier? Of course you do, well science may just have the answer! Scientists have discovered an on-and-off “switch” in cells that may hold the key to healthy aging. This switch points to a way to encourage healthy cells to keep dividing and generating, for example, new lung or liver tissue, even in old age. Getting cells to divide might not be that hard (or even very useful), but that isn’t all, it gets better!
I’m sure you can all relate, you go to fix the sink and in the process you build a new kitchen on accident. Anyone… no? Well that is sort of what happened to researchers recently, while developing a new cancer drug, they discovered that mice lacking a specific protein live longer lives with fewer age-related illnesses. The mice, which were bred to lack the TRAP-1 protein, demonstrated less age related tissue degeneration, obesity, and spontaneous tumor formation when compared to normal mice. Pretty awesome if you think about the fact that the findings could change how scientists view the metabolic networks within cells.
Recently on Lunatic Laboratories we reported on a new path to the fountain of youth that had been found [at least for mice]. Well today, we are happy to announce that another road to the fountain of youth has been potentially discovered. This time the discovery was made by Harvard Stem Cell Institute [HSCI] and Stanford researchers.
Being the over achievers they are, they released not one, not two, but three studies showing that substances in the blood of young mice rejuvenate the brain and muscles of aging mice. Two of those three studies, by Harvard researchers were released early online just yesterday, but won’t be published until later this week in the journal Science. The two are similar to the third [albeit not connected], Stanford study that suggests the same reversal of aging also happens to their hearts.
The fountain of youth, as it turns out, isn’t so much a fountain, it’s a new drug. There has been countless dollars thrown at anti-aging research, some producing better results than others. So when scientists at northwestern medicine in collaboration with Tohoku University in Japan, released a new study I am sure there was more than one happy person seeing the results.
The team, building on previous research, have managed to extend the life of accelerated aging mice more than four times longer than the control group. All thanks to an experimental drug — not only did it extend the life, it also protected the lungs and cardiovascular system from aging.
