Can We Reverse Anti-Aging With Research From The Academy Of Medicine?

At GettingOlderNews, we help people who want to learn more about aging and anti-aging.

Modern medicine provides some modest increases to human lifespan but is far from providing life-extending technologies. The new Academy hopes to become the focal point for research on lengthening health plans and combatting age-related illnesses.
O’Rourke and her colleagues suspected that one key to increasing longevity among worms might lie in activating autophagy – a process for recycling old or broken cells – but were uncertain of its role.

Can the Percec Anti-Aging Lab Unlock the Secrets of Youth?

Percec Anti-Aging Lab’s focus lies on anti-aging research and life extension therapies while creating induced pluripotent stem cells as a potential way to reverse aging-related diseases.
Research of this nature remains very experimental, but could have significant improvements on people’s quality of life. Reprogramming human stem cells has been found to reverse aging processes and extend mice lifespan by 30%; furthermore it reduces cancer cells within the body while helping protect against neurodegenerative disorders such as Alzheimer’s.
Scientists have also recently made the remarkable discovery that reprogrammed stem cells can rejuvenate older cells by resettling the cellular clock and decreasing oxidative stress – two major contributors to cell aging. This breakthrough opens the way for anti-ageing medicine with this unique approach.
At present, one of the best ways to fight aging is through physical activity and exercise, specifically targeted at improving muscle function, metabolism and digestive health – and possibly mental wellbeing as well. Another good strategy to combat aging would be maintaining a healthy diet with regular supplement intake such as vitamins.
Another method for combatting anti-aging is receiving regular health checkups that include tests for blood pressure, hormone levels, sensory function and free radical and antioxidant balance in your body. Doing so can help avoid age-related diseases as well as equipping patients with the knowledge they need to live longer, healthier lives.
Although the Fountain of Youth may only exist as a myth, scientists are hard at work looking for an anti-aging cure. One recent breakthrough comes from Babraham Institute researchers in the UK. Through genetic modification, they were able to regress 53-year-old skin cells by 30 years in a petri dish, making them look and behave as younger skin cells should do – therefore providing hope of treating conditions associated with aging such as premature skin aging.

Can the Yamanaka Factors Unlock the Secret to Eternal Youth?

Shinya Yamanaka discovered in 2006 that four proteins (Oct3/4, Sox2, Klf4, and c-Myc) could reverse highly specified cells, such as skin cells, back into stem cells via “epigenetic reprogramming,” earning him the 2012 Nobel Prize for Physiology or Medicine. When administered appropriately, epigenetic reprogramming can rejuvenate aging cells throughout the body while improving various signs of aging in mice.
Multiple research groups have discovered that epigenetic reprogramming may help reverse certain signs of human aging; however, its exact mechanism remains unknown and whether this reversal can occur without inducing pluripotency and giving rise to cancerous tumors.
Yuancheng Lu of Sinclair Lab Genetics sought to determine this. To do this, he genetically fused three of the four Yamanaka factors with a harmless virus and then injected this mixture into the retina of an aged mouse, where rejuvenated cells not only rebuilt damaged retinal ganglion neurons but even produced new axons that send signals between eye and brain.
Results were stunning: rejuvenated mice had younger-looking eyes and lived longer lives, and cells showed patterns of DNA methylation that were more typical of younger cells. Sinclair and his team now plan to use Yamanaka’s method of reprogramming to combat other signs of aging symptoms.
One drawback of this approach is that Yamanaka factors cause various types of cancer in laboratory mice; thus researchers would like to create a safer and more selective therapy using this approach. In order to do so, they must understand how epigenetic reprogramming occurs within human cells.
Research findings may lead to treatments that slow the progress of aging by targeting specific age-related diseases such as Alzheimer’s or diabetes, or lifestyle interventions which affect aging processes such as exercise or calorie restriction; intermittently pulsing Yamanaka factors could make lifestyle interventions even more effective, creating next-generation regenerative therapy which could become available within less than a decade.

Can Detoxifying Glycerol and Glyceraldehyde Reverse Aging?

Glycerol and glyceraldehyde are toxic by-products of fat metabolism that accumulate over time in our cells. Previous aging research on mice, worms and human cells led to researchers believing that autophagy (renewing broken and old parts of the cell) was essential to increasing longevity; however, UVA scientists discovered that simply stimulating one gene, adh-1, led it to produce more alcohol dehydrogenase which helped combat toxic by-products such as glycerol and indirectly glyceraldehyde; this resulted in improved health and lifespan by 50%!
Glyceraldehyde can be broken down via three distinct pathways in humans. First, triokinase converts it to GAP which then enters the glycolytic pathway; alcohol dehydrogenase then converts this D-glyceraldehyde back to D-glyceraldehyde that eventually is converted to triglycerides via gluconeogenesis; or alternatively it can be directly transformed to glycerol by Glycerol-3-phosphate dehydrogenase which bypasses both steps altogether.
As these pathways can contribute to toxicity, it’s vital that their levels remain as low as possible – one of the primary goals of enzymatic detoxification of glycerol and glyceraldehyde. This process relies on various enzymes like glycerol kinase, triokinase, cytosolic glycerol-3-phosphate deshydrogenase, mitochondrial glycerol-3-phosphate dihydrogenase as well as aldehyde reductase (also known as NADP-dependent alcohol dehydrogenase).
Glycerol produced using this process has superior storage properties over that produced through other processes, containing minimal amounts of glyceraldehyde and dihydroxyacetone and lasting for up to eight weeks at 40deg C storage temperatures. Furthermore, this method enables production of high purity glycerol that can be used in pharmaceutical and cosmetic production.
The UVA team is researching the role of this gene in aging, hoping to test whether activating it extends mouse lifespan. After conducting in vitro experiments on human cells to see if activation reduces or delays the onset of markers of cellular aging, they plan on looking into developing drugs targeting this gene to treat age-related diseases if their findings prove promising. O’Rourke suggests this could either be taken as a comprehensive anti-aging measure or focused on each disease individually.

Can Embryonic Stem Cells Unlock the Secret to Eternal Youth?

Embryonic stem cells (ESCs) are pluripotent cells, meaning they can differentiate into any cell type within the body. As such, ESCs provide the “raw material” from which more specialized cell types such as those responsible for organs and tissues like bone, muscle, skin, blood liver pancreas are created. ESCs can be found within an embryo’s inner cell mass for four days after fertilization before reaching blastocyst stage and begin their transformation process.
Researchers have developed techniques for manipulating cells into specific types, like heart cells. Unfortunately, however, no way has yet been discovered to ensure these newly formed cells will be safe and effective when transplanted into humans; additionally these cells tend to proliferate irregularly and specialize spontaneously, making large-scale production more challenging.
Human embryonic stem cells provide valuable insight into the molecular mechanisms behind various diseases and may help contribute to their prevention or cure. Furthermore, using embryonic stem cells allows researchers to test drug compounds safely within human bodies to identify any side effects or assess whether or not they could potentially be dangerous.
These cells can also be used to study the development of human bodies, specifically to detect and prevent congenital diseases and birth defects. Embryonic stem cells may be obtained through donated embryos from fertility clinics or created using somatic nuclear transfer, a technique that involves cloning living organisms. Some may object to using human embryonic stem cells due to beliefs that life begins at conception.
Adult stem cells are generally uncontroversial as they occur naturally within adult tissue, such as bone marrow, fat (adipose tissue), peripheral blood, and dental pulp. Adult stem cells can help repair damaged cells caused by diseases like multiple sclerosis, spinal cord injuries and diabetes as well as age-related conditions like osteoarthritis. Scientists have begun coaxing adult cells back into pluripotency; once perfected this could eliminate the need to create embryos through SCNT research and reduce or eliminate ethical concerns surrounding such research.
