How to Change Your (Mini) Mind: 5hmC’s Role in Neurodevelopment and Alzheimer’s DiseaseJune 13, 2021Although it may seem like neurodevelopment and neurodegeneration don’t have much in common, exciting new results on the dynamics of 5hmC in forebrain organoids may just change your mind. 5hmC is enriched in the brain, important in neurodevelopment, and suspected to be relevant to Alzheimer’s Disease (AD) progression. However, due to a lack of human samples and appropriate disease models it has been difficult to study how 5hmC distribution changes during early brain development and AD. In […]
An Inclusive EWAS Filters Through the Trans-ethnic and Ethnic-specific DNA Methylation Profiles of Kidney FunctionJune 11, 2021Diversity and inclusion are important components of our modern society, and epigenomics is no exception. To build on our knowledge of ethnic differences and similarities, an inclusive epigenome-wide association study (EWAS) of kidney function has come forth to filter the hits. A group led by Charles Breeze (National Cancer Institute) and Nora Franceschini (University of North Carolina) conducted […]
Caffeine Fix Showdown: The Impact of Coffee and Tea on DNA Methylation and Disease RiskMay 27, 2021While a mug of dark roasted coffee can jump-start your day and a cup of fragrant tea may soothe frayed nerves after a grueling session in the lab, a highly-caffeinated new study now shows that these hot beverages also impact human health by influencing DNA methylation. Previous caffeine-fueled studies have provided contrasting views on how […]
Where’s the Cancer Driver? MethSig Cuts Through the Background Noise to Identify Oncogenic Promoter HypermethylationMay 26, 2021As any TikTokker, Zoom presenter, or amateur photographer worth their salt can tell you, sometimes a good background is all you need to make your content really pop. It turns out that the same principle applies when trying to figure out which promoter DNA hypermethylation events drive tumor growth. MethSig, a new algorithm developed by Heng Pan in Dan Landau’s group at Weill Cornell Medicine, improves […]
Timing is Everything – Even for Maintaining the Global Epigenetic State of Human Cells!May 17, 2021They say that timing is everything – from the perfect golf shot to the most cutting joke – and now, a well-timed study establishes that DNA replication timing is everything when it comes to maintaining the global epigenetic state of human cells! Studies had previously described a link between the temporal order of DNA replication […]
scCUT&Tag: The Cutting Edge of Single-Cell Histone Modification ProfilingMay 11, 2021While we’re usually fans of shortcuts that make our lives easier, this exciting combination of accessible methods to profile single-cell chromatin modifications has our attention, no matter how you slice it. Chromatin profiling using cleavage under targets and tagmentation (CUT&Tag) allows you to investigate histone post-translational modifications and transcription factor occupancy, particularly when limited by […]
Fortune Telling with EPICOVID – A Novel DNA Methylation Signature that Predicts COVID-19 SeverityMay 9, 2021DNA methylation signatures can function somewhat like a fortune teller’s crystal ball – foretelling those patients with poor prognosis and helping to choose the optimal treatment strategy. By gazing into the crystal ball of the COVID-19 methylome, a fortune-telling team led by Manel Esteller (Josep Carreras Leukaemia Research Institute, Barcelona, Spain) and Aurora Pujol (Bellvitge […]
PANDORA-seq Opens a Pandora’s Box of sncRNAsMay 2, 2021The opening of Pandora’s box is said to have cursed the ancient Greek world with sickness, death, and innumerable other evils. Thankfully, a modern-day technique called “PANDORA-seq” brings forth new hope for removing these ancient afflictions on our epigenomes by identifying previously undetectable small non-coding RNAs (sncRNAs). A hopeful handful of researchers led by Qi […]
DNA Methylation Signature Defines a Second Neurodevelopmental Disorder Associated with SRCAPApril 27, 2021Sometimes the only way to tell who’s who is with their signatures. It turns out that epigenetic signatures can tell one disorder from another, and even help find new ones. Chromatin remodelers play important roles in neurodevelopmental disorders (NDDs). Pathogenic genetic variants in many of these genes cause specific NDDs. These are often associated with […]
QSER1 Teams up with TET to Protect the Developmental Secrets of DNA Methylation ValleysApril 23, 2021Believers in the Sasquatch say deep mountain valleys are where they may be hiding. When it comes to our genomes, DNA methylation valleys hold secrets yet to be discovered too. How DNA methylation is coordinated at multiple CpGs sites across regulatory regions in early development is still poorly understood. Bivalent promoters are one system used […]
