eBook: Aging and EpigeneticsJune 8, 2018This eBook explores various levels at which aging and epigenetics are related. Assembled are summaries of studies exploring specific questions regarding the epigenetic basis of aging and aging-related conditions. They are divided into four chapters: 1. DNA Methylation Epigenetic Clock 2. Anti-aging 3. Alzheimer’s Disease 4. Stem Cells
EpiTOF Histone Modification Analysis Reveals How Aging Cells Grow Apart!May 9, 2018Some say that all babies look the same – small, warm bags of tears and mayhem – with significant differences only appearing as we grow older and grow apart from our newborn brethren (and sistren!). Our burgeoning epigenome may react to aging in a very similar manner, with age-related losses and gains of DNA methylation combining […]
TERRA lncRNA Tailors a Trimethylation Trio at TelomeresApril 27, 2018A good tailor will make any scientist look presentable in an expensive suit or a glitzy dress (when we escape the confines of a lab coat) and now, the group of Maria A. Blasco (CNIO, Madrid, Spain) describes how long non-coding RNAs (lncRNAs) tailor our telomeric DNA with just enough trimethylated histones to suit any […]
If You Snooze, You Lose: DNA Methylation Loss at Late Replicating Regions Tracks Cellular AgingApril 13, 2018“Early to bed and early to rise makes a man healthy, wealthy, and wise!” While many night owls happily ignore this sage advice and enjoy a few extra hours in bed in the mornings, a new study regarding DNA methylation dynamics in normal and cancer cells gives credence to the old axiom “If you snooze, […]
A Long non-coding RNA Superhero is GUARDIN our Genome from DNA Damage!April 4, 2018Batman swoops through Gotham, Supergirl flies over National City, and the Black Panther keeps his keen eyes on Wakanda; every superhero acts as a guardian of the beloved place they call home, protecting from any number of devious and dastardly threats. Now, researchers from the laboratory of Xu Dong Zhang and Mian Wu (Henan Provincial […]
Embrace Your Age! Age-related H4K16ac Gains Protect Your Brain from Developing Alzheimer’s DiseaseMarch 19, 2018In our quest for the fountain of youth, we often find ourselves attracted to anything that will fight off the signs of aging. But now, the first genome-wide analysis of a specific histone modification in the brains of human patients affected by Alzheimer’s disease (AD) demonstrates that we should embrace the epigenetic changes that come […]
Cutting Through the Epigenetic Complexities Linking Aging and TumorigenesisMarch 16, 2018Writing your first grant proposal? Optimizing that tricky Western blot? Programming an old PCR machine? Only a few things are more complex than our current understanding of the epigenetic links between aging and tumorigenesis, but this has not stopped a few valiant labs from doubling down and busting a few paradigms while they are at […]
Old Fathers Pass on an Unwanted Aging DNA Methylation Profile to the Next GenerationMarch 1, 2018Great looks, a well-worn leather jacket, and a wide-ranging collection of old vinyl records represent great examples of inheritances that fathers happily pass on to their grateful children. However, new findings from the lab of Dan Ehninger (German Center for Neurodegenerative Diseases, Bonn, Germany) show that older dads can also pass on an intergenerational effect […]
Epigenetic Aging Analysis Suggests That TERT Isn´t the Anti-aging Target You Are Looking For!February 13, 2018This isn’t some sort of Jedi mind trick, we promise, but TERT may not be the anti-aging target you are looking for! TERT, or telomerase reverse transcriptase, plays an essential role in the elongation and maintenance of telomeres and as telomeres shorten with age, many surmise that activation of TERT represents an exciting approach to […]
Like a Fine Wine, Histone Variant H2A.Z Represses Memories and Accumulates with Age!February 6, 2018While aging works wonders for the taste of our ever-accumulating wine collection, the passage of the years is not as kind to our memories! To fully decipher the processes underlying learning and memory differences in the aging brain, the lab of Iva Zovkic at the University of Toronto Mississauga (Canada) recently expanded on past work […]
