One of the biggest breakthroughs in biology in the last few decades has been the discovery of epigenetics. Rather than changing the genes themselves, epigenetics change how genes are expressed, allowing our cells to differentiate between their various types. However, the epigenetics of our cells change over time. There is some debate over how much…

A new publication highlights how the complex interaction of NAD+ and cellular senescence pathways may complicate proposed anti-aging therapies that boost NAD+ using precursors. What are epigenetic alterations? One of the proposed reasons we age is the changes to gene expression that our cells experience as we get older; these are commonly called epigenetic alterations….

The researchers of a new publication take a look at the effects of obesity on aging and consider its impact in the context of the Hallmarks of Aging, a popular theory that breaks down aging into nine distinct processes. The case for obesity accelerating aging Being overweight and carrying excessive amounts of visceral fat, a…

At the Undoing Aging 2019 conference, we had the opportunity to interview Yuri Deigin, the CEO of Youthereum Genetics. His company is developing therapies that focus on OSKM, the Yamanaka factors known for turning cells back into a pluripotent state. By partially reprogramming cells using a single component of OSKM, Oct4, the company hopes to…

We have talked about the potential of partial cellular reprogramming in previous articles, and today, we want to draw attention to a new paper that promises to further refine reversal of epigenetic aging in cells. As we age, our cells experience alterations to their epigenetic markers, and this changes gene expression, which is proposed to…

The role of epigenetics, which determine how your genes are expressed, is being increasingly implicated in aging, as is the potential of therapies that revert epigenetics back to those of a younger person. What are epigenetic alterations? The DNA in each of our cells is identical, with only some small variations, so why do our…

Researchers at the Harvard T.H. Chan School of Public Health have discovered a new aging clock that can accurately determine both chronological and biological age in a wide variety of species. Aging and the nucleolus There are two kinds of age: chronological age, which is strictly the number of years that something has lived, and…

For the June edition of Journal Club, we will be taking a look at the recent paper entitled “Changes at the nuclear lamina alter binding of pioneer factor Foxa2 in aged liver“. We summarized the research in an article earlier this month. Summary Increasing evidence suggests that regulation of heterochromatin at the nuclear envelope underlies…

Researchers at the University of Virginia School of Medicine have discovered that as we age, our cells’ nuclear membranes become misshapen, which stops our genes from working properly. Nuclear membranes become distorted with age The DNA in all our cells is the same; however, the cells in our body show a great range of variation…

The Undoing Aging conference, a joint effort between the SENS Research Foundation and Michael Greve’s Forever Healthy Foundation, took place on March 15-17 in Berlin, gathering many aging researchers, advocates, investors, and other important members of the longevity community in one place. As we invited one of the best Russian journalists at educating the public…
