Can Engineering Chromodomains Take Histone Methylation to “Affinity” and Beyond!?December 4, 2022The troupe of “toys” we use to explore the world of histone methylation just gained a new friend thanks to a playful team of epigenetic engineers who have taken histone modification-reading chromodomains to “affinity” and beyond! Researchers led by Gianluca Veggiani (Louisiana State University, USA) and Sachdev Sidhu (University of Waterloo, Canada) knew that histone-modification […]
Can New RNA Modification Profiling Tools Help in Your Epitranscriptomic Bid for Glory?November 21, 2022Two new sequencing methods may just make your day if you happen to be bidding for glorious insights into the epitranscriptome. Inspired by the bisulfite conversion used to assay DNA methylation, BID-seq and GLORI now enable single-nucleotide transcriptome-wide profiling of two crucial RNA modifications – N6-methyladenosine (m6A) and pseudouridine (the C5-glycoside isomer of uridine). RNA […]
An Inflammatory Microclimate Seeds a Super-enhancer That Drives TumorigenesisNovember 7, 2022While microclimates shape environments along coastlines and urban jungles, this phenomenon isn’t restricted to macroscopic landscapes; now, a new study provides evidence that inflammatory signaling from the tumor microenvironment (TME) alters the epigenetic landscape by inducing the formation of a super-enhancer (SE) that drives tumorigenesis. An environmentally-friendly team led by Ramon E. Parsons (Icahn School […]
An Eerie Epigenetic Disguise Helps SARS-CoV-2 Avoid Anti-viral ResponsesOctober 25, 2022Every avid trick-or-treater aspires to have the perfect Halloween costume; now, a spooky study has revealed how an unwanted guest – SARS-CoV-2 – dons an epigenetic disguise to help this virus trick its way past host defenses to infect human cells! A fearless team led by Erica Korb (University of Pennsylvania, USA) knew that SARS-CoV-2 […]
RT&Tag Maps the Fleeting World of Chromatin-associated RNAsOctober 25, 2022Between the vast lands of DNA and proteins lies the ephemeral and dynamic world of chromatin-associated RNAs, a less-explored but utterly critical domain of the eukaryotic nucleus. Thankfully, RNA-focused researchers can now turn to a tagmentation-based profiling technique (“RT&Tag”) to map the landscape of regulatory chromatin-associated RNAs to aid this quest. In their fascinating study, […]
Single-Cell Spatial and Multimodal Upgrades to ATAC-Seq Speed Up Your Chromatin InsightsOctober 9, 2022Need to get swiftly up to date with recent advances to the assay for transposase-accessible chromatin with high-throughput sequencing (ATAC-Seq) technique? Well, slow down and read on for the latest single-cell spatial and multimodal updates to your chromatin toolbox! Our first study gives us a quick lowdown on Spatial-ATAC-seq, a technique to capture spatial chromatin […]
RNA Methylation and DNA Demethylation Teamwork Make the Transcriptional Dream WorkSeptember 25, 2022Dream teams come in all shapes and sizes, from the 1970 Brazil football team to the Mercedes F1 team of the 2010s. A new epigenetic alliance formed between RNA methylation and DNA demethylation recently made its competitive debut and now shows how teamwork makes the dream work! A synergistic team led by Dongxin Lin, Jian […]
eBook: Epigenetics of COVID-19September 22, 2022COVID-19 has been one of the biggest public health issues in recent history and has changed the daily lives of almost everyone on the planet. Many researchers, biotechnology and pharmaceutical companies have been working around the clock since the novel coronavirus outbreak started to try to develop new tools to test for and treat the […]
Brain Cells Choose Cilia Over Social Media to Make Exciting New Connections!September 19, 2022When was the last time you made an exciting new connection? At an international conference, the coffee shop, or social media? A welcoming new study now provides evidence that brain cells don’t go to these lengths or even have to take a standard synaptic approach; instead, they use a connection – an axo-ciliary synapse – […]
Keeping Aging in LINE by Stabilizing HeterochromatinSeptember 11, 2022Like many aspects of our lives, epigenetic processes can get out of control during aging. Now, exciting new findings have revealed that the secret to keeping our aging epigenomes “in line” is removing LINE-1 RNA from cells, which stabilizes heterochromatin and reverses signs of aging! Previous studies have shown how age-associated heterochromatin loss associates with […]
