Paried-Tag Pairs Up ChIP-Seq and RNA-Seq for Single-Cell MultiomicsMarch 2, 2021With Valentines day just behind us, a new genome-wide assay has reinforced the perks of pairing up for single-cells. While multiomic methods have been gaining momentum, it has been tricky for researchers to play matchmaker with ChIP-seq at the single-cell level. To meet this challenge, the lab of Bing Ren at the University of California […]
dCas9-dMSK1 Provides the Potent Power of Programmable Histone PhosphorylationFebruary 20, 2021Time to move over histone methylation, the potent activating power of programmable histone phosphorylation joins the dCas9 epigenome editing toolbox and shows how it takes histone acetylation along for the ride. A rather active team of researchers led by Isaac B. Hilton (Rice University, Houston, TX, USA) knew that phosphorylation represents one of the most […]
It Takes Two to Tango: Histone Serotonylation Partners with H3K4me3 to Regulate Gene ExpressionFebruary 15, 2021While epigenetic research has often linked single histone modifications to transcriptional outputs, new research in neurons now shows that “it takes two to tango” and a little serotonin, classically known as a neurotransmitter, keeps the transcriptional tango going strong. Specifically, a free-stepping study that discovered histone serotonylation previously associated an adjacent enrichment of the lysine […]
Big Things Come in Small Packages: Nanobodies Enter the Epigenetic Editing RingFebruary 4, 2021While we have seen many contenders for the title of heavyweight champion in the epigenetic editing ring, the adage “big things come in small packages” has taken on a new meaning. Nanobodies, or single-domain antibodies, demonstrate that featherweights can pack an explosive epigenetic editing punch by using their opponents’ momentum against them. Researchers led by […]
EpiGo-KRAB: A New, Live-action Tool to Edit and Visualize Heterochromatin Formation in Living ColorJanuary 26, 2021Like any live-action remake, vibrant colors are essential for a new epigenetic editing tool that simultaneously introduces H3K9me3 at hundreds of targeted loci while also allowing for HD visualization of the heterochromatic results. Now, let’s meet the stars of this show that were cast by a team led by Hanhui Ma from ShanghaiTech University. H3K9me3 […]
Sperm Throw “Three-pointers” to Ensure Transgenerational Epigenetic InheritanceJanuary 26, 2021In the game of transgenerational epigenetic inheritance, many labs have been searching for a slam dunk. Now, in a game-changing new article, ballers from the laboratory of Michael K. Skinner (Washington State University, Pullman, WA, USA) provide a play-by-play of how teamwork between non-coding RNA expression, DNA methylation, and histone modifications allows rat sperm to […]
NanoNOMe Combines Nanopore and NOMe-seq to Mine the Allele-specific EpigenomeJanuary 18, 2021Gnomes are small magical creatures that mine for treasures, so you might wonder if a nanoNOMe is an even tinier being. Well actually it’s a new molecular technique, but its applications are nothing short of magical. Several methods have been developed to probe DNA methylation, transcription factors, and chromatin state simultaneously. Many are based on […]
Reprogramming Helps to “Turn Back Time” on the Epigenetic Clock and Restore Lost VisionDecember 14, 2020Back in the days of big hair and masses of leather, Cher wanted to “turn back time” if she could find a way! Well, get your stockings and suspenders ready and head for the docks, as her eighties “vision” may be on the cusp of coming true with the help of epigenetic reprogramming! Specifically, resear-Cher-s […]
Blame the Brain on Cocaine: DNA Methylation Alters 3D Chromatin TerrainDecember 8, 2020Although studies of DNA methylation and its impact on chromatin architecture leave us with quite the buzz, this latest one adds a bit of cocaine to the mix to give it an extra kick. This stimulating study found cocaine use reduced DNA methylation at a key gene to change CTCF binding and alter 3D chromatin […]
Epigenetic Silencing of the Y-chromosome Controls the Extent of Male ToxicityDecember 7, 2020While “toxic masculinity” may seem intimately linked to the human species, the fruit fly Drosophila has come to show us that their Y-chromosome acts as a source of genomic male “toxicity” that epigenetic silencing keeps in check. Specifically, we know that the formation of silent heterochromatin domains during development represses the activity of transposable elements […]
