Epigenetics Alone Can Drive Cancer—No Mutations Needed

May 13, 2024

Epigenetics has moved into the driver’s seat. In a first-of-its-kind study, a talented team show that knocking down polycomb group proteins in Drosophila causes tumors to form, and bringing the proteins back doesn’t fix it. The finding demonstrates that transient epigenetic changes can irreversibly drive cancer—without genetic mutations. Although we’ve suspected that epigenetic mechanisms could take […]

The Force is Strong with Histone H1.0: How Extracellular Stress Regulates Cell Mechanics through Chromatin Structure

May 6, 2024

Scientists have longed to use “The Force” – provided by intracellular entities known as midichlorians – to help around the lab; now, an epigenetic alliance reports that an intracellular fibroblast component – Histone H1.0 – uses The Force and orchestrates cell mechanics when facing Sith-like evils such as physical/chemical stressors. The force is strong with […]

Pregnancy Epigenetically Ages Mothers – But Breastfeeding May Reverse It

April 22, 2024

Our mothers might be onto something when they jokingly blame us for their gray hair and wrinkles. In two recent studies, DNA methylation-based epigenetic clocks show that pregnancy, with its far-ranging emotional and physical changes, increases the biological ages of mothers. On the bright side, the effects were reversible in those who breastfed, according to […]

This is Your Epigenetic Wake Up Call! Don’t Sleep on NAP-seq When Searching for ncRNAs

April 21, 2024

Has searching for ncRNAs left you needing forty winks? Maybe take a short rest and dream-a-little-dream, but don’t sleep on a brand new technique known as napRNA sequencing or NAP-seq, which represents a wake-up call to the epigenetics field by providing the ability to describe novel classes of human regulatory non-coding or ncRNAs! Wakey-wakey! RNA […]

A Selfish, Poisonous Element Could Set the Evolutionary Stage for Genomic Imprinting

April 15, 2024

A selfish toddler might throw a tantrum to get their way, but in worms, a “selfish” piece of DNA known as a toxin-antidote (TA) element uses something more sinister—poison. Researchers have just discovered a parent-of-origin effect with this nematode element that could be an evolutionary precursor of genomic imprinting. Led by Alejandro Burga (Institute of Molecular […]

EvoETR Epigenome Editor Helps Maintain Cholesterol Levels by Silencing Pcsk9

March 25, 2024

Ever wanted to cut a bad thing out of your life? Well, perhaps the secret to success doesn’t involve any cutting (of your DNA). In some people, a mutant PCSK9 gene interferes with the liver’s job to get rid of LDL, aka “bad” cholesterol. Now, researchers have developed an all-in-one “evolved engineered transcriptional repressor” (EvoETR) […]

No Epigenetic Modification is an Island: How Reader Proteins Functionally Interpret Complex Chromatin States

March 25, 2024

Like no man is an island and instead relies on those surrounding them, single epigenetic modifications generally do not function in solitary. Now, an absorbing new study from a synergistic epigenomics squad reports how epigenetic reader proteins functionally interpret chromatin states made up of complex combinations of disparate epigenetic modifications. A highly collaborative team guided […]

Gut Microbiota Uses the Histone Code to Make Intestinal Cells Speak Their Language

March 19, 2024

A growling stomach represents a clear sign that you must eat something tasty; however, sometimes, your digestive system is where the message needs to go! An exciting epigenetics study reveals that our gut microbiota employs a histone code via histone acylations to influence gene expression in intestinal cells, forcing these cells to speak their language! […]

reChIP Doubles Down on Low-input Profiling of Bivalent Chromatin

March 5, 2024

Sometimes, when you’re dealt the right hand, doubling down is a sound strategy. Although it can be a risky move in blackjack, a new ChIP-seq method makes it a sure thing when you’re dealing with bivalent chromatin. The strategy, which includes important preparation steps and two rounds of chromatin immunoprecipitation (ChIP), provides sensitive genome-wide profiles […]

Updated cfDNA Nucleosomics Technology Upgrades our Epigenetic Clocks

March 4, 2024

A new style, novel functionalities, and a better overall product; we always want our smartwatches to employ the latest technology, and why not?! Now, a well-timed update involving cell-free DNA (cfDNA) nucleosomics-based technology provides for a significantly upgraded epigenetic clock, which may boost aging-based research. A punctual team led by Vladimir B. Teif (University of […]
