Cancer Cells Get in Shape Using Circular Extrachromosomal DNA with Highly Accessible ChromatinDecember 3, 2019Cancer cells run rings around their normal counterparts in terms of proliferation, survival, migration, and aggressivity to devastating effect, but how do cancer cells get themselves “in shape” to allow for these strenuous activities? Previously, researchers led by Howard Y. Chang (Stanford University), Bing Ren, Vineet Bafna, and Paul S. Mischel (University of California at […]
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 […]
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 […]
Single Cell Analyses Reveal How Epigenetic Drift Makes Stem Cells Age Badly!October 28, 2019While cheese and wine (and whisky!) all get better with age, the human body fares less well! Although partaking in too many culinary delights hardly helps, studies have established the reduced number and activity of stem cells as a cause for the age-related deterioration of various tissue types. With this in mind, a talented team […]
Foretelling Future Hippocampal Transcription and Disease Risk with Early DNA Methylation ProfilesOctober 27, 2019Will it rain tomorrow? Will I ever win the lottery? Will our new paper finally be accepted!? Unfortunately, we have yet to come up with a sturdy means to predict our fates far in the future; however, new research by Hadad and colleagues now suggests that DNA methylation profiles in young cells accurately foretell changes […]
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 […]
DNA Methylation Analysis Puts a Face to a Very Ancient NameOctober 1, 2019A long, long time ago, in a land far, far away (2014 at the Hebrew University of Jerusalem, Israel actually!) a team of researchers banded together under the leadership of Liran Carmel and David Gokhman. Rather than inventing the wheel or devising a strategy to capture wooly mammoth, the team developed a way to reconstruct […]
