A Good Friend is Forever: DNMTs and Histone ComplexesJanuary 26, 2015It’s not always easy to find good friends, but recent work has found that the de novo DNA methyltransferases DNMT3A2 and DNMT3B1 are far from socially awkward. Baubec et al. from the Swiss team lead by Dirk Schübeler uncovered some companions of these DNMTs by profiling their binding in embryonic stem cells (ESCs) through streptavidin […]
Intergenerational Epigenetic Effects of Dad’s DietJanuary 23, 2015The effect of epigenetic marks across generations has helped bring epigenetics to the public eye like never before. The health implications are enormous and so is the contribution to basic science, particularly evolution. However, one important distinction is whether it is a true form of molecular inheritance, known as transgenerational epigenetic inheritance, or the shared effect […]
Webinar: A Step-by-Step Guide to ChIP-Seq Data AnalysisJanuary 12, 2015In this webinar, Dr. Xi Chen takes publicly available real ChIP-seq data sets to show you how to perform ChIP-seq routine analysis using a combination of different online tools available. This provides an opportunity for bioinformatics beginners and wet-lab biologists who do not have much experience with unix operating systems to have an idea about […]
Sperm-Derived Histone Modifications Orchestrate Human Paternal Heterochromatin FormationJanuary 11, 2015Humans have developed elaborate systems such as script, books, computers and virtual networks to ensure that knowledge is preserved throughout multiple generations. Researchers led by Ester Baart at Erasmus MC in the Netherlands wanted to understand and uncover other mechanisms – in particular those developed by cells to preserve their epigenetic knowledge over generations. Owing to […]
Hi-C Captures KNOT: A Chromatin Conformation for all ChromosomesJanuary 1, 2015Putting a modern twist on the holiday spirit, researchers from the University of Zurich (Switzerland) gift a new piece of chromatin architecture that welcomes each and every chromosome to its party. And it comes from a surprisingly festive plant; Arabidopsis. On a Hi-C run surveying chromatin architecture, the touring researchers encountered a number of landmarks. At first they came across the standard sights: […]
A “Grandiose” Project Provides a Fuzzy New Future for iPSC ResearchDecember 17, 2014Induced pluripotent stem cell (iPSCs) research burst on to the scene in 2006 with a paper which has since spawned thousands of studies and has proved to be a quantum leap for regenerative medicine. This reached a crescendo this year when a Japanese patient became the first recipient of retinal cells generated from iPSCs made […]
Histone H2A.Z Subunit Exchange Controls MemoryDecember 17, 2014Memory is one fancy cellular function that seems to be the niche of the epigenome. Through it a cell can remember its identity and past exposures. But what about that other type of memory? Ya know, neuroepigenetic memory. We’ve already seen that histone methylation has a role in long-term memories and altered histone acetylation (H4K12) is involved […]
Alpha-ketoglutarate: Small Metabolite With Big Influence on Stem Cell PluripotencyDecember 15, 2014Many of us go through the morning ritual of picking up store-brewed coffee, although we could just as easily make it ourselves. Most mammalian cells feel the same about glutamine, which they require in abundance, even though glutamine is a non-essential amino acid. Now, stem cell researchers from Memorial Sloan Kettering Cancer Center show that glutamine […]
Epigenetic Exploitation of Host Cells by VirusesDecember 14, 2014Exploitation is a common theme in all fields of biology and viruses are no exception. But now it seems that viruses are up to some creative tricks when it comes to keeping a low profile in preparation for their full attack and sneaking out a few infections, a process known as viral latency. While DNA methylation may function as […]
Epigenetics Mediates Immortality of Adult Stem CellsDecember 13, 2014What would you do to ensure your immortality? Drink a potion? Cast a spell? Or even set out on an expedition to find the fountain of youth? Researchers from the Adult Stem Cell Technology Centre in Boston, USA have discovered that adult stem cells in the mouse have another more intricate strategy towards living forever […]
