Tracking cancer’s immortality factor

Posted by in categories: biotech/medical, life extension

Canadian scientists have achieved a first in the study of telomerase, an essential enzyme implicated in aging and cancer.

In today’s edition of the prestigious journal Molecular Cell, scientists from Université de Montréal used advanced microscopy techniques to see single molecules of telomerase in living .

A flaw in the replication of chromosomes means that they get shorter with each . If nothing is done to correct this error, replication stops and cells go into a state called senescence, a hallmark of aging. Normally, telomerase adds extra DNA to the ends of chromosomes to prevent this problem, but as we age our bodies produce fewer of them.

Best DNA Tests for Health and Longevity

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

Has anyone here done a DNA test for longevity? I’m curious if you have any experiences with specific companies you can share. I researched 7 different big ones and am trying to decide which to go with.


Note: This is the second in our series of posts about the best DNA tests for health and longevity. To better understand the basics of DNA and the different types of DNA tests on the market please go back and read the first piece on The Benefits of Genetic Testing for Longevity.

Seeing the Future: Longevity Research and Glaucoma (Video)

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

Dr David Sinclair (Harvard) : “I want to mention one thing that nobody except the insiders would know, is that I was at a conference a couple weeks ago with all 15 of us talking about this reprogramming work, and a lot of it is not published yet. I’ve seen things that make my head spin, the ability to turn back aging in a whole animal,…”


On October 27, 2020, Glaucoma Research Foundation presented the 2020 Weston Lecture featuring a talk by world-renowned Harvard Medical School genetics researcher and best-selling author David Sinclair, PhD, AO discussing longevity research and glaucoma.

Senotherapeutic peptide reduces skin biological age and improves skin health markers

Posted by in categories: biotech/medical, life extension

Hi everybody. Today, it was published a paper in which it’s described the research that led to the identification and testing of a peptide that reduces the amount of senescent cells in the skin, and that peptide is being used in the first product in the whole world (as far as I know) that is already in the market and reduces the amount of senescent cells in humans (in this case, in the skin). The paper can be found in I don’t think it’s an ordinary thing that a product that reduces the amount of senescent cells is being sold in the market. After many years watching Aubrey de Grey’s talks, and reading news about promising researches about senescent cells, and about the formation of many companies to research how to reduce the amount of senescent cells, finally there is something that reached the public. This paper is very important as it allows that the rejuvenation field analyzes it and be prepared to seize this opportunity to show to the world, in practice, that the theoretical base of the rejuvenation therapies can be translated to practice and rejuvenate the human body — in this case, the skin. As some of you already know, the company which organized this research and launched the product is OneSkin, and its CEO, Carolina Reis, has been presenting their research in several conferences in the rejuvenation field in the last months. OneSkin is a company with its interests, of course, but at the same time is a representative of the rejuvenation field which is opening a path for all the other companies.


Skin aging has been primarily related to aesthetics and beauty. Therefore, interventions have focused on reestablishing skin appearance, but not necessarily skin health, function, and resilience. Recently, cellular senescence was shown to play a role in age-related skin function deterioration and influence organismal health and, potentially, longevity. In the present study, a two-step screening was performed to identify peptides capable of reducing cellular senescence in human dermal fibroblasts (HDF) from Hutchinson-Gilford Progeria (HGPS) patients. From the top four peptides of the first round of screening, we built a 764-peptide library using amino acid scanning, of which the second screen led to the identification of peptide 14. Peptide 14 effectively decreased HDF senescence induced by HGPS, chronological aging, ultraviolet-B radiation, and etoposide treatment, without inducing significant cell death, and likely by modulating longevity and senescence pathways. We further validated the effectiveness of peptide 14 using human skin equivalents and skin biopsies, where peptide 14 promoted skin health and reduced senescent cell markers, as well as the biological age of samples, according to the Skin-Specific DNA methylation clock, MolClock. Topical application of peptide 14 outperformed Retinol treatment, the current gold-standard in anti-aging skincare. Finally, we determined that peptide 14 is safe for long-term applications and also significantly extends both the lifespan and healthspan of C. elegans worms tested in two independent testings. This highlights the potential for geroprotective applications of the senotherapeutic compounds identified using our screening platform beyond the skin.

Scientists have reversed some signs of aging in a study on mice

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

Mice who ate a diet high in fat and cholesterol were more likely to see their hair turn from black to white and experience hair loss. The diet also appeared to cause inflammation of the skin.

In the first stage of the study, the researchers genetically modified mice to develop atherosclerosis, a condition in which fat deposits form in the arteries.

They then fed mice either a Western diet high in fat and cholesterol or untreated rat chow from the age of 12 to 20 weeks. As expected, the mice who consumed the Western diet saw their hair turn white and fall out, and develop skin lesions. And the longer the mice ate the diet, the worse their symptoms became. By week 36, three quarters of the animals had skin lesions.

Slower Biological Aging In People On A Calorie Restricted Diet

Posted by in categories: biological, food, life extension

Here’s my latest video!


Calorie restriction (CR) is well known to extend average and maximal lifespan in a variety of animal models, but what about in people? In this video, I present evidence showing that CR slows biological aging, which suggests that CR will positively affect lifespan in people.
