Research has shed new light on genetic processes that may one day lead to the development of therapies that can slow, or even reverse, how our cells age.

A study led by the University of Exeter Medical School has found that certain genes and pathways that regulate splicing factors – a group of proteins in our body that tell our genes how to behave—play a key role in the ageing process. Significantly, the team found that disrupting these genetic processes could reverse signs of ageing in cells.

The study, published in the FASEB Journal, was conducted in human cells in laboratories. Aged, or senescent, cells are thought to represent a driver of the ageing process and other groups have shown that if such cells are removed in animal models, many features of ageing can be corrected. This new work from the Exeter team found that stopping the activity of the pathways ERK and AKT, which communicate signals from outside the cell to the genes, reduced the number of senescent cells in in cultures grown in the laboratory. Furthermore, they found the same effects from knocking out the activity of just two genes controlled by these pathways—FOX01 and ETV6.

A wonderfully written, very friendly essay on the discoveries, carrier and life of Prof Dr David Sinclair and of course on sirtuins, the epigenetic theory of aging, resveratrol, nicotinamide dinucleotide NAD+ and healthy aging.

Since my recent visit to the Harvard Medical School laboratory run by Australian geneticist David Sinclair, I’ve been struggling with a shamefully greedy impulse. How can I get my hands on the wonder molecules that Sinclair is trialling to amazing effect in mice, not only slowing down their ageing but reversing it? My fear of missing out has flared up since I learnt from Sinclair that he estimates at least a third of his scientific colleagues are taking some version of these “anti-ageing” molecules, just as he does, in the belief it will increase their health spans by as much as 10 years. This means not just having a chance at living an extra decade, but living it in good health, avoiding the age-related diseases and general frailty that can make those years harrowing.

It becomes difficult to remain impartial when a respected scientist tells you he will soon turn 50, does not have a single grey hair and, according to regular blood and genetic tests, has the biological age of 31.4, even though he’s a workaholic and doesn’t exercise much. Or that he likes to think his mother prolonged her life – post lung cancer, with only one lung – for 20 years by taking the molecules he gave her, and that his 79-year-old father, who has taken several different kinds of them for years, currently lists whitewater rafting and mountaineering among his hobbies. Sinclair’s wife, Sandra Luikenhuis, even gives these molecules to the family dogs. (Luikenhuis, who has a PhD in genetics from Massachusetts Institute of Technology, only began taking the molecules herself after she noticed the irrefutably positive effect they’d had on their pets.)

It has recently been suggested that humans could live to 150 by 2020 simply by taking a certain supplement.

A wide panel discussion on the anti aging biotechnology is taking place now. I will mention only the important lecture on senescent cells, aging and drugs given this afternoon by Dr Judith Campisi (Buck Institute for research on Aging), the small big woman scientist!

Here in beautiful Basel, Switzerland we open the section Aging and Drug Discovery, actually an intersection of AI, longevity and drug discovery in the Innovation Forums of Basel Life Conference 2018. Dr Alex Zhavoronkov (InSilico Medicine) and Dr Morten Scheibye-Knudsen (University Copenhagen) welcomed us. Dr Jay Olshansky (University of Illinois at Chicago) gave the first lecture. Some examples for age face recognition were shown, emphasising the importance of wrinkles from smoking or others and suggesting that looking younger means living longer! After the wonderful lecture I immediately went to correct my make-up!

Β-hydroxybutyrate seems to prevent senescence of vascular tissue.

According to a study by Georgia State University scientists, a molecule called β-hydroxybutyrate has anti-aging effects on the vascular system; more specifically, the molecule appears to prevent senescence of vascular cells by promoting cellular quiescence instead [1].

Descartes once described the human body as a “fleshy machine” and today’s transhumanists would likely agree.

Philosopher Nick Bostrom writes that as we seek to peer farther into posthumanity our ability to concretely imagine what it might be like trails offend that the very essence of posthumanity is to be able to have thoughts and experiences that we cannot readily think or experience with our current capacities.

ATLANTA—A molecule produced during fasting or calorie restriction has anti-aging effects on the vascular system, which could reduce the occurrence and severity of human diseases related to blood vessels, such as cardiovascular disease, according to a study led by Georgia State University.

“As people become older, they are more susceptible to disease, like cancer, cardiovascular disease and Alzheimer’s disease,” said Dr. Ming-Hui Zou, senior author of the study, director of the Center for Molecular and Translational Medicine at Georgia State and a Georgia Research Alliance Eminent Scholar in Molecular Medicine. “Age is the most important so-called risk factor for human disease. How to actually delay aging is a major pathway to reducing the incident and severity of human disease.

”The most important part of aging is vascular aging. When people become older, the vessels that supply different organs are the most sensitive and more subject to aging damage, so studying vascular aging is very important. This study is focused on vascular aging, and in old age, what kind of changes happen and how to prevent vascular aging.”
