There’s CoREST for the Wicked: An Epigenetic Switch for Social Behavior in Worker AntsNovember 23, 2019“All work and no play” is the norm for carpenter ants, where epigenetically distinct workers spend their days toiling away for their genetically identical colony-mates. The two classes of worker ants, minor workers who forage for food and major workers who protect the colony, differ in their size and appearance, but new research suggests that […]
Inside Job: dCas9 Hijacks Endogenous Chromatin Machinery to Modulate Gene ExpressionNovember 22, 2019In the newest spy movie hitting theaters this month, undercover agents sneak inside the innermost sanctum of fortress walls to hijack nuclear weapons…err nuclear machinery to upregulate gene expression. Spoiler alert, we’ll even reveal the agents’ identities: it’s catalytically dead Cas9 (dCas9) with a small molecule associate, teaming up to complete the mission. While other […]
Deciphering the Warburg Effect: The Metabolic By-product Lactate Modifies HistonesNovember 14, 2019Like the energy drink cans and protein bar wrappers that litter the table after an epic writing session, by-products generally represent undesirable items created during the generation of a more desirable object. Recycling can put some writing by-products to further use, and studies have now highlighted that biological by-products derived from cellular metabolism can also […]
Histone Hangover: Alcohol Metabolism Actively Alters Acetylation in the BrainNovember 4, 2019We’ve all been warned — from our teachers, our parents, or from outrageous college movies — if you overindulge with booze you may not remember much the next morning. Now, exciting new research shows that an alcohol metabolite can alter our brain’s histone acetylation and can mix up memories at the molecular level. Neurons make […]
Studying TAD Boundary Issues Through Epigenome Editing of CTCF MotifsOctober 19, 2019So, your therapist says you have boundary issues? Well you’re not alone; CTCF is known to play a critical role in setting the boundaries of topologically associating domains (TADs), but there’s been no therapist to uncover their definitive impact. Thankfully, new research from the lab of Bradley Bernstein at the Harvard Medical School (Boston, USA) […]
It’s a Bear, It’s a Pig, it’s a Tardigrade! Superhero Dsup Protein Protects Chromatin from HarmOctober 19, 2019Some superheroes wear flashy costumes and capes that you can’t help but notice, but then there’s the unassuming tardigrade; the microscopic wonder beast with the astounding ability to survive extreme temperatures, radiation, and the vacuum of space! With multiple secret identities, including “water bear” and “moss piglet”, the discrete invertebrate has kept the key to […]
Gut Microorganisms Make Epithelial HDAC3 Work to their RhythmOctober 7, 2019While many of us prefer the sound of silence, others feel the need to inject a little rhythm into their everyday lives; but how do you do it? Spinning a few records at home, moving to the beat at Samba lessons, or do you use the microorganism-mediated activity of Hdac3 in your gut?! While researchers […]
Webinar: The Epigenetics of the Exposome and Aging – Paul G. ShielsOctober 2, 2019Don’t miss this great webinar detailing some of the latest discoveries about the role of epigenetics in aging. Aging results in a gradual and progressive loss of physiological functions and physical abilities over time. Overcoming the growing burden of age-related issues is one of the greatest challenges facing modern society. These issues are leading to […]
Sherlock Genomes: Stimulation Leaves Epigenetic Evidence Behind in NeuronsSeptember 30, 2019Even the most careful criminals leave some kind of evidence; a fingerprint or a strand of hair can be enough for a clever investigator to link them to the scene of the crime. Although it’s far from an open and shut case, new research in mice shows that the epigenome of neurons contains chromatin clues […]
The Tn5 Transposase Takes Single-cell ChIP-Seq to the Next LevelSeptember 18, 2019It’s never good to see someone lagging behind the rest, but while stepwise developments to single-cell chromatin immunoprecipitation and subsequent parallel sequencing techniques (ChIP-seq) have led to gradually improved yields and increased sensitivity with reduced numbers of cells since the first report of a single-cell ChIP protocol, we still lack widely-applicable and low-cost methods to […]
