Simulations open a new way to reverse cell aging

Posted by in categories: biotech/medical, engineering, life extension, neuroscience

Simulations that model molecular interactions have identified an enzyme that could be targeted to reverse a called cellular senescence. The findings were validated with laboratory experiments on and equivalent tissues, and published in the Proceedings of the National Academy of Sciences (PNAS).

“Our research opens the door for a new generation that perceives aging as a reversible biological phenomenon,” says Professor Kwang-Hyun Cho of the Department of Bio and Brain engineering at the Korea Advanced Institute of Science and Technology (KAIST), who led the research with colleagues from KAIST and Amorepacific Corporation in Korea.

Cells respond to a variety of factors, such as oxidative stress, DNA damage, and shortening of the telomeres capping the ends of chromosomes, by entering a stable and persistent exit from the . This process, called cellular senescence, is important, as it prevents damaged from proliferating and turning into . But it is also a natural process that contributes to aging and . Recent research has shown that cellular senescence can be reversed. But the laboratory approaches used thus far also impair tissue regeneration or have the potential to trigger malignant transformations.

Innate immune system: Natural killer cells and cancer

Posted by in categories: biotech/medical, life extension

https://www.BetaGlucanShop.com — Natural killer cells (NK cells) are the most aggressive cells of your immune system and kills through apoptosis, also known as programmed cell death. These innate immune cells are key players against viral infections and cancer growth.

Natural killer cells help prevent metastasis by killing abnormal cells and tumour cells. Metastasis is the spread of cancer from one part of the body to another. Beta glucans are used in immunotherapy as they may help (depending on type) the immune system distinguish between healthy and abnormal cells like cancer cells, and thus direct the immune cells to engage cancer cells.

Drug reverses age-related cognitive decline within days

Posted by in categories: biotech/medical, life extension, neuroscience

Just a few doses of an experimental drug can reverse age-related declines in memory and mental flexibility in mice, according to a new study by UC San Francisco scientists. The drug, called ISRIB, has already been shown in laboratory studies to restore memory function months after traumatic brain injury (TBI), reverse cognitive impairments in Down Syndrome, prevent noise-related hearing loss, fight certain types of prostate cancer, and even enhance cognition in healthy animals.

In the new study, published December 1, 2020 in the open-access journal eLife, researchers showed rapid restoration of youthful cognitive abilities in aged mice, accompanied by a rejuvenation of brain and that could help explain improvements in brain function.

“ISRIB’s extremely rapid effects show for the first time that a significant component of age-related cognitive losses may be caused by a kind of reversible physiological “blockage” rather than more permanent degradation,” said Susanna Rosi, Ph.D., Lewis and Ruth Cozen Chair II and professor in the departments of Neurological Surgery and of Physical Therapy and Rehabilitation Science.
