A team of researchers affiliated with a host of institutions across Japan has found that inhibiting kidney-type glutaminase-dependent glutaminolysis in mice can lead to elimination of senescent cells. In their paper published in the journal Science, the group describes using RNA interference to look for enzymes that are required for senescent cell survival and subsequently inducing them to die. Christopher Pan and Jason Locasale, with the Duke University School of Medicine, have published a Perspectives piece in the same journal issue outlining research into glutamine and the role it played in the work done by the team in this new effort.

Cells are described as senescent when they lose the ability to divide. Prior research has found that cells can reach senescence due to exposure to stress, which can include mitochondrial, replicative or oxidative stress. In all cases, the cells live and continue to function, but can no longer divide. Prior research has found evidence suggesting that senescent cells play a role in the development of some aging-related diseases such as arteriosclerosis and muscle degeneration. For that reason, scientists have been looking for ways to eliminate them. In this new effort, the researchers have found a way to rid test mice of senescent cells by removing a pathway necessary for their continued survival.

The work involved a screening effort using RNA interference to look for enzymes that senescent cells need to survive. This led them to look closer at glutamine metabolism, specifically glutaminase 1. Testing showed it to be critical to survival for senescent cells. The team then inhibited the glutaminase 1 pathway in test mice. After allowing time for the changes to take effect, the researchers found that inhibiting the pathway led to the deaths of senescent cells. In the longer term, they found that it also reduced age-related organ problems and also health issues related to obesity.

“By contemplating the full spectrum of scenarios of the coming technological singularities, many can place their bets in favor of the Cybernetic Singularity which is the surest path to cybernetic immortality and engineered godhood as opposed to the AI Singularity when Homo sapiens is hastily retired as a senescent parent. This meta-system transition from the networked Global Brain to the Gaian Mind is all about evolution of our own individual minds; it’s all about our own Self-Transcendence.”-Alex M.

The many things you should know about the field of cryonics. The Cryonics Symposium International takes place Saturday in Hollywood, Fla.

It can be done. And it can be done sooner than many realise…even within YOUR lifetime. Imagine… Reaching triple digits with the health, fitness and body of an athletic 30 year old… It is entirely within reach now, it may be even less than a decade away. All we need to do is repair the damage that living and our metabolism create, it is slowly accumulating, which is why it takes 7 or 8 decades to rear its ugly head in most people, so one treatment should keep things under control for many years, and by then science will have advanced immeasurably, improving the treatments to whole new levels… Then you can dream of reaching 4 digits…then 5…then 6… BUT You need to stay in good enough shape to last long enough to see the treatments perfected and available. So watch your diet, your mental and physical health, your weight, and look to use occasional fasting, and time restricted eating, along with saunas and cold showers (or any hot/cold therapy), etc., to keep yourself at your optimum until that days arrives. If you want to know more, then this video breaks it down into even more detail. Have a great day and enjoy your journey into the future…

Summary: Scientists have long marveled at the rejuvenating effects of heterochronic parabiosis. When you mix the blood of a young mouse and an old mouse by joining their circulatory systems, the older animal recovers some features of youth, while the young animal becomes functionally older. While many have assumed that these effects were driven by the infusion of pro-youth factors from the young parabiont into the older one, an alternative “Dilution Solution” hypothesis is possible: that the young blood is instead diluting pro-aging factors from the old animal’s blood, as well as allowing the young animal’s livers and kidneys to filter out metabolic toxins through the young animals’ livers and kidneys.

In heterochronic parabiosis, joining the circulatory systems of young and old mice causes the older animal to recover some features of youth. The effect has been widely assumed to be driven by pro-youth factors in younger blood, but an alternative hypothesis is possible: that the procedure is instead diluting pro-aging factors in the older partner.

“In their work, Hamiliton’s team found that the Dunkin Hartley guinea pig was a good candidate for a muscle aging model due to the animal’s tendency to develop osteoarthritis (OA) at a young age.”

There are many components to aging, both mental and physical. When it comes to the infrastructure of the human body—the musculoskeletal system that includes muscles, bones, tendons and cartilage—age-associated decline is inevitable, and the rate of that decline increases the older we get. The loss of muscle function—and often muscle mass—is scientifically known as sarcopenia or dynapenia.

UC San Francisco scientists have discovered a new way to control the immune system’s “natural killer” (NK) cells, a finding with implications for novel cell therapies and tissue implants that can evade immune rejection. The findings could also be used to enhance the ability of cancer immunotherapies to detect and destroy lurking tumors.

The study, published today (January 82021) in the Journal of Experimental Medicine, addresses a major challenge for the field of regenerative medicine, said lead author Tobias Deuse, MD, the Julien I.E. Hoffman, MD, Endowed Chair in Cardiac Surgery in the UCSF Department of Surgery.

“As a cardiac surgeon, I would love to put myself out of business by being able to implant healthy cardiac cells to repair heart disease,” said Deuse, who is interim chair and director of minimally invasive cardiac surgery in the Division of Adult Cardiothoracic Surgery. “And there are tremendous hopes to one day have the ability to implant insulin-producing cells in patients with diabetes or to inject cancer patients with immune cells engineered to seek and destroy tumors. The major obstacle is how to do this in a way that avoids immediate rejection by the immune system.”
