CRISPR-Cas9 Embryo Editing…….Of Mice and Men!September 27, 2017Presumably after a day spent in a local tavern instead of writing and editing verse, the famous Scottish poet Robert Burns noted that “The best laid schemes of mice and men, Often go awry”. However, a new study of genome editing in the embryos of mice and men led by Kathy K. Niakan (Francis Crick […]
LINE-1 Retrotransposons Keep Early Embryonic Chromatin in LineSeptember 10, 2017While cocktails and embryonic development usually don’t mix well, a cocktail of three transcription-activator-like effectors (TALEs) has just shaken up our understanding of the role LINE-1 retrotransposons during early embryonic development. LINE-1 activation had been considered a consequence of developmental processes, but now a talented team from the lab of Maria-Elena Torres-Padilla at the German […]
Genome Protection in the Embryo: A Big Role for Small RNAs!July 27, 2017It’s not how big it is, it’s what you do with it that counts. Here at Epigenie, we don’t think that size matters, as evidenced by our excitement over studies showing that small RNAs in sperm can mediate huge intergenerational effects related to paternal exercise and diet! Now, a fascinating study from the lab of […]
Exploring the TERRA Incognita of Long Non-Coding RNAs!July 14, 2017Decades of diligent exploration in the mammalian genome has led to the discovery that while only around 2% of this base-pair jungle represents protein-coding sequence, over 90% of our genome gets transcribed into RNA species such as long non-coding RNAs (lncRNAs). However, our knowledge base on many lncRNAs remains in “terra incognita” with scant details […]
Genome Architecture of Single Cells May Shape Reprogramming to TotipotencyApril 5, 2017The soaring Eiffel Tower in Paris, the tumultuous Guggenheim in Bilbao, or the intricate genome structure of a single cell; which architectural marvel impresses you the most? For the labs of Leonid A. Mirny and Kikuë Tachibana-Konwalski, the latter looms above any such extravagant edifice, but the available analytical tools lacked the resolution required for […]
CLEVER Technique Maps the 5-Formylcytosine Landscape during DNA DemethyationMarch 31, 2017Mapping an undulating, dynamic, and partially hidden landscape represents a vexing problem to say the least, especially when the landmarks of interest are rare DNA demethylation by-products in a single cell! This is the task faced by those intrepid explorers hoping to map the genome-wide location of 5-formylcytosine (5fC), a fleetingly rare oxidized form of […]
Gene Body DNA Methylation Keeps Cells Fit and HealthyMarch 9, 2017Boots, check! Helmet, check! DNA Methylation, check? Any active individual will tell you that protecting your body is an integral part of keeping fit and healthy while enjoying your sport of choice. In the über-competitive world of DNA, a study from the teams of Francesco Neri and Salvatore Oliviero has proposed that DNA methylation on […]
Optogenetic Epigenetic Editing of DNA Methylation Puts You in Control of Stem Cell FateFebruary 16, 2017In Greek mythology, the fates forge the strings of life that control our lives and choose the moment of its end. We mere mortals yearn for such powers and we are now one step closer to the light thanks to an optogenetic epigenome editing system that lets you write and erase DNA methylation to control […]
Histone Modification Imaging Pr-EDICTS Stem Cell FateJanuary 27, 2017Will it rain? Will my team win? Will I get that grant? There are instances where a glance into a fortune-teller’s crystal ball could definitely give you the upper hand. Although the crystal ball is a myth, researchers from the lab of Prabhas V. Moghe (Rutgers University, New Jersey, USA) have recently developed a means […]
Mapping mRNA Methylation in the Mouse: From ESCs to the BrainJanuary 23, 2017As Ptolemy and other noteworthy cartographers will tell you, a detailed and up-to-date map is always useful. This navigational tool has guided many intrepid explorers from familiar regions towards the unknown with the promise of discovery and adventure! In the linear world of ribonucleic acid (RNA), intrepid researchers have mapped the locations of the N6-methyladenosine […]
