NANOG’s Prion-like Behavior Builds Bridges to PluripotencyMay 11, 2022In both the literal and figurative sense, building bridges can really get you places! Knowing this, genome engineers and epigenetic architects recently created a blueprint demonstrating how a pioneer transcription factor – NANOG – uses prion-like behavior to form gel-like protein condensates that create interstrand DNA “bridges” to reorganize chromatin and clear a rapid path […]
EPIC Technique Infers Gene Expression from Cell-free DNA FragmentationMay 9, 2022It’s time to put down that well-thumbed copy of Homer’s Odyssey, as there is a new epic in town. Now, the “epigenetic expression inference from cell-free (cf)DNA-sequencing” (EPIC-seq) technique heroically enables gene expression analysis using a process known as “fragmentomics.” Circulating cfDNA comes as nucleosome-associated fragments that reflect the chromatin configuration in the cell of […]
Battling Against the Clock: Epigenetic Age Acceleration Impacts COVID-19 SeverityMay 2, 2022Timing is crucial for many aspects of life, and now, a rather timely study demonstrates that the acceleration of our epigenetic clocks after SARS-CoV-2 infection significantly impacts our risk of suffering severe COVID-19 and post-COVID-19 syndrome (“long COVID”). Previous research has described how older patients suffer from a higher risk of developing severe COVID-19 (independent […]
Rixosomes Take Out RNA to Keep Silent Polycomb-target Genes Quiet!May 2, 2022Some pesky Polycomb-target genes know too much about genome-wide goings-on, and while these nervous sections of DNA might keep silent for now, how can we ensure that our cells maintain this code of silence? It turns out that human cells, just as in yeast, possess an enforcer that mercilessly chops up RNA messages produced from […]
EpiDamID Contains a Flood of Histone Modification Findings from Single Cells!May 2, 2022Lately, we’ve been faced with a veritable torrent of awesome single-cell epigenomics methods; thankfully, the development of a new technique – EpiDamID – promises to easily contain the floods of findings regarding histone modification and gene expression patterns coming from single cells! Previously, a talented team from the lab of Jop Kind (Hubrecht Institute, Utrecht, […]
Cell Surface Protein Profiling Gives Single-cell CUT&Tag a Pro UpgradeApril 25, 2022Nothing beats a Pro upgrade, and lately, researchers have given CUT&Tag the deluxe treatment. This chromatin profiling method received its first improvements with the releases of scCUT&Tag and then Spatial-CUT&Tag; now, we’ve been treated to a view of the cell surface protein profile in its latest form. A pro team of single-cell explorers from the […]
Single-cell Based DNA Methylation Deconvolution Method Scores Another Goal for EpigeneticsApril 25, 2022You might think you know the leading players in the field of computational epigenetics; however, each new season brings forward a squad of exciting new players eager to prove their worth. Recently, one of these players EpiSCORE-d the goal of extending in silico cell-type deconvolution of human epigenomic data to many tissues. While reference-based cell-type […]
APOE Tips Heterochromatin Balance Towards Stem Cell Senescence and AgingApril 11, 2022Like a healthy balance between work and play can enhance our day-to-day lives, a new study suggests that stem cells require a healthy epigenetic balance between silent and active chromatin domains to support their ongoing normal functions. More specifically, researchers headed by the well-balanced quartet of Moshi Song, Weiqi Zhang, Jing Qu, and Guang-Hui Liu […]
Has Cannabis Gone Up in Smoke? – Study Links Use to Accelerated Epigenetic AgingMarch 31, 2022Like there is no smoke without fire, another study has linked cannabis use to unwanted epigenetic alterations. We’ve seen that cannabis exposure alters DNA methylation in prenatal mouse brains (influencing subsequent behavior), the sperm of rats and humans (priming an autism spectrum disorder-like profile), and human adult brains (impacting brain function), and now epigenetic aging […]
DNA Methylation Provides New Insight into the Missing Heritability of ALSMarch 31, 2022The devastating and fatal neurodegenerative disease amyotrophic lateral sclerosis (ALS) has an estimated heritability rate of around 50%, suggesting that a considerable portion of disease risk derives from environmental and lifestyle risk factors that can leave their mark on the epigenome. Can DNA methylation analysis provide new insight into the missing heritability of ALS? In […]
