DNA Methylation: The Original Anti-Virus ProgramJanuary 8, 2014Security and anti-virus software is a must-have accessory for the internet age, but it turns out that DNA methylation has been protecting us all from retroviral infections for quite a bit longer than any computer program. A talented research team lead by Richard Meehan from the University of Edinburgh (Scotland) applied HELP-seq analysis and DNA methylation […]
Decrypting Transcription with Dr. Frank GrosveldJanuary 7, 2014Dr. Frank Grosveld points out how little we actually know about the details of transcription and the molecular machinery involved. Transcription Factories We have this loop structure of the genome. And at the same time, we know that every gene that’s being transcribed, that’s active, is part of what we call transcription factories. So […]
Epigenetic Technology: 2013 Editor’s FavoritesDecember 18, 2013In 2013, technology impacted nearly every facet of our lives: from improving Instagram selfies, to squeezing even more knowledge from epigenetics research. Check out some of our favorite Technology features from the past year: Genome Editing We love the potential of Genome Editing. Led by methods like CRISPR-Cas, this emerging field has really boomed this […]
Epigenetics 101: You Can’t Always Blame Your Parents with Alberto PerezDecember 17, 2013EpiGenie reader Dr. Albert Perez lays out some of the basic concepts behind epigenetics, and explains how being a red-head in Spain started him on a path to explore DNA and the epigenome.
Webinar: Covering all the Bases with Genome-Wide 5-mC and 5-hmC SequencingDecember 17, 2013Covering all the Bases with Genome-Wide 5-mC and 5-hmC Sequencing By Dr Keith Booher, PhD. Manager of Epigenetic Services at Zymo Research Abstract: There is an ever-increasing appreciation for the remarkable ability of epigenetic modifications, such as the methylation of cytosines in DNA (5-mC), to respond to environmental cues and influence gene expression in biological […]
Promega SIRT-Glo™ Assays Illuminate the Search for SirtuinsDecember 11, 2013Sirtuins (SIRTs) sure seem to getting around. These energetic class III HDAC enzymes have their fingerprints on everything from Alzheimer’s to Inflammation, generating enough spotlight (and even a little controversy) to make even Kanye West a feel little jealous. Promega’s new SIRT-Glo™ Assays and Screening Systems are the latest tool to help researchers study the […]
Modifying Our View of Histones with Dr. Jerry WorkmanDecember 3, 2013Dr. Jerry Workman discusses the questions surrounding the preservation of histone marks, and the balance between histone turnover and transgenerational inheritance. The Dynamic Histone Code I think one of the most exciting things for me that’s being approached in the field more recently is how are histone marks preserved? We talk about these things carrying […]
The Loose Ends in the Chromatin-Transcription Relationship with Dr. Steven HenikoffDecember 3, 2013Dr. Henikoff discusses some of the gaps in our understanding of transcription and chromatin that still need to be filled in. The Unknowns of RNA Polymerase-Nucleosome Interactions Well, you would think with so much work done on the relationship between transcription and chromatin, the fact that there’s so many meetings on it and all. We […]
Genome Synthesis vs. DNA Methylation: A Battle for One-Carbon with Dr. Patrick StoverNovember 19, 2013Dr. Patrick Stover discusses the competition between genome synthesis and DNA methylation for the use of available folate and one-carbons. The Balancing Act of Folate Metabolism So one of the primary focus of our laboratory is trying to link how changes in metabolism affect specific disease outcomes. And we’re most interested in neural tube defects […]
Methylcytosine Makes its Mark on RNA MethylationNovember 6, 2013Methylcytosine – It’s not just for DNA anymore. Despite being almost exclusively associated with DNA for decades, methylcytosine (5mC) has recently been shown to be an important base modification in RNA as well. Exploding interest in the RNA version of 5mC, what it does, and how it works, has been sparked by a sharp uptick […]
