TAME Trial for the Effects of Metformin in Humans to Proceed this Year
Researchers and advocates have been trying for some years to launch the TAME trial to assess the effects of metformin on aging in humans. This is not with the hope of producing meaningful effects on the progression of aging. Metformin has a small effect size, being one of the less effective interventions that upregulates cellular stress responses, a strategy that in and of itself is weak in long-lived species such as our own. The goal is to push the FDA into accepting clinical trials that target mechanisms of aging rather than a specific named age-related condition. Metformin was chosen because its safety profile, widespre...

In conclusion, our data show how oncogenic and tumor-suppressive drivers of cellular senescence act to regulate surveillance processes that can be circumvented to enable SnCs to elude immune recognition but can be reversed by cell surface-targeted interventions to purge the SnCs that persist in vitro and in patients. Since eliminating SnCs can prevent tumor progression, delay the onset of degenerative diseases, and restore fitness; since NKG2D-Ls are not widely expressed in healthy human tissues and NKG2D-L shedding is an evasion mechanism also employed by tumor cells; and since increasing numbers of B cells express NKG2D ...

Jim Mellon Interviewed by Adam Ford at Undoing Aging 2019
Adam Ford of Science, Technology, and the Future carried out a number of interviews while at Undoing Aging in Berlin earlier this year. The interview materials are steadily being processed and uploaded, and that just recently included this interview with Jim Mellon, billionaire investor and philanthropist, cofounder of Juvenescence, and a very down to earth fellow who is interested in improving the human condition by targeting aging with new biotechnologies. Accordingly, he has used his resources to put himself into a position to talk up the longevity industry, move research forward, and attract a great deal more funding f...

In this study we show, for the first time, significant alterations in cholesterol efflux capacity in adolescents throughout the range of BMI, a relationship between six circulating adipocyte-derived EVs microRNAs targeting ABCA1 and cholesterol efflux capacity, and in vitro alterations of cholesterol efflux in macrophages exposed to visceral adipose tissue adipocyte-derived EVs acquired from human subjects. These results suggest that adipocyte-derived EVs, and their microRNA content, may play a critical role in the early pathological development of ASCVD.

MKSAP: 45-year-old woman with type 2 diabetes mellitus
Test your medicine knowledge with the MKSAP challenge, in partnership with the American College of Physicians. A 45-year-old woman is evaluated for management of type 2 diabetes mellitus diagnosed 3 months ago. She was asymptomatic at diagnosis with an initial HbA1c value of 9.7%. Her initial interventions included lifestyle modifica tions with weight loss and metformin. She is […]Find jobs at Careers by KevinMD.com. Search thousands of physician, PA, NP, and CRNA jobs now.

The Role of mTOR as a Regulator of Lifespan
The mTOR gene is deeply involved in the regulation of cellular activities in response to nutrient sensing. It is also implicated in the many, many changes that occur to slow aging in response to a restricted calorie intake, including processes known to be important to aging such as mitochondrial function and cellular senescence. Given that most research to date on intervention in the aging process has focused on the calorie restriction response and related upregulation of stress response mechanisms, it is no surprise that mTOR has attracted a lot of attention. The first mTOR inhibitor drugs are already going through clinic...

Landmark Results Achieved in Aging and Chronic Disease: Danish Group Extends Disease-free Life by 8 Years
By WILLIAM H. BESTERMANN JR., MD
New Scientific Breakthroughs Can
Provide a Longer Healthier Life
Twenty-one years of follow-up comparing usual care with a protocol-driven team-based intervention in diabetes proved that healthy life in humans can be prolonged by 8 years. These results were achieved at a lower per patient per year cost. Aging researchers have been confident that we will soon be able to prolong healthy life. This landmark study shows this ambitious goal can be achieved now with lifestyle intervention and a few highly effective proven medications. These medications interfere with the core molecular biol...

In this study, a significant (30%) increase in maximum lifespan of mice was found after nonablative transplantation of 100 million nucleated bone marrow (BM) cells from young donors, initiated at the age that is equivalent to 75 years for humans. Moreover, rejuvenation was accompanied by a high degree of BM chimerism for the nonablative approach. Six months after the transplantation, 28% of recipients' BM cells were of donor origin. The relatively high chimerism efficiency that we found is most likely due to the advanced age of our recipients having a depleted BM pool.
In addition to the higher incorporation rates, ...

An Interview with Jim Mellon of Juvenescence at Undoing Aging 2019
The Life Extension Advocacy Foundation was not the only group conducting numerous interviews at the recent Undoing Aging conference in Berlin. Representatives of the German Party for Health Research were also set up with a camera and interviewer. The video here is their interview with billionaire Jim Mellon, one of the founders of Juvenescence. He is notable in our community for being one of the first high net worth individuals to fully and publicly back the SENS view of aging in both word and deed. SENS tells us that aging is caused by molecular damage, and that periodically repairing that damage is the way to produce rej...

The Healthy Longevity Global Grand Challenge at the National Academy of Medicine
The institutions of the world are slowly waking to the potential of treating aging as a medical condition, thereby postponing, reversing, and ultimately entirely preventing age-related disease. The side-effect will be greatly extended lives, lived in good health, in youthful vigor. Aging is the accumulation of cell and tissue damage, and rejuvenation is the periodic repair of this damage. The research and development communities are only just starting on the road of damage repair in medicine. The first rejuvenation therapies, in the form of senolytic treatments to selectively destroy senescent cells, are only now emerging....

This study provides a possible reason why genes carrying health risks have persisted in human populations. The second found evidence for multiple variants in genes related to ageing that exhibited antagonistic pleiotropic effects. They found higher risk allele frequencies with large effect sizes for late-onset diseases (relative to early-onset diseases) and an excess of variants with antagonistic effects expressed through early and late life diseases.
There also exists other recent tangible evidence of antagonistic pleiotropy in specific human genes. The SPATA31 gene has been found under strong positive genomic sele...

SGLT-2 Inhibitors as Calorie Restriction Mimetics
SGLT-2 inhibitors, or gliflozins, are a newer and still expensive class of anti-diabetic drug. They work by interfering in the trafficking of glucose, preventing the kidney from reclaiming glucose and introducing it back into the bloodstream. The glucose is instead excreted. Analogously to metformin, another anti-diabetic drug, it is proposed that inhibition of SGLT-2 in some ways mimic the effects of calorie restriction, triggering beneficial cellular housekeeping mechanisms that usually only turn on during periods of fasting or low calorie intake. Size of effect and degree of side-effects are always the questions in thes...
