Spotlight on Emerging RNA Methylation Analysis TechniquesDecember 9, 2013Taking cues from ultra-talented entertainers like Justin Timberlake, methylation is out to prove it’s possible to be successful in more than just one medium. Recent research has found that methylation can pull off its’ gene expression regulatory magic at the level of RNA too. And no, we’re not talking about other RNA modifications, like 6-methyladenosine […]
Long Intergenic Non-Coding RNAs, One of Life’s Bare EssentialsDecember 4, 2013If you were forced to choose a few bare essentials for a lengthy stay on a deserted island, most of us would choose items like some great tunes, a favorite book, or a loved one, but some new research points out that lincRNAs ought to be considered too, since a clever crew at Harvard has recently […]
lncRNA Gets Classy: Chromatin Signatures Distinguish SpeciesDecember 4, 2013Everyone wants to be judged based on their own merits, and not just what group they happen to be a part of. With the help of a talented crew from the University of Oxford, lncRNAs have just been given a wonderful holiday gift to help them break free of their one-size-fits-all stereotype; two distinct classes […]
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 […]
Epigenetics & Cancer & Gene Networks …Oh Me(thylation)!November 15, 2013Now that we’ve landed smack dab in the middle of the age of big data, some interesting techniques have emerged to interrogate the mind-boggling amounts of information from our (epi)genome. Dr. Ranjan Perera and team at the Sanford-Burnham Medical Research Institute (Florida) applied some of that new analysis wizardry to learn more about the complexity of […]
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 […]
Natural (Epi)genetic Variation: A Role for Lineage Determining Transcription FactorsOctober 25, 2013The intimate tango between epigenome and evolution has just taken an interesting spin. With 88% of candidate loci from GWAS (genome wide association studies) pointing toward non-coding regions, the potential for acquired epigenetic marks to explain missing heritability, cross generations, and add variety to populations, offers huge potential for understanding natural variation and evolution, which […]
Enhancer Transcribed RNAs No Longer Just Second Banana to PromotersOctober 24, 2013Enhancer regions are starting to come into their own as important members of the epigenome – way more than just add-ons that increase promoter transcription. A new study shows us that the RNA world just won’t stop expanding. Drs. Rao and Yuan from the Blood Center of Wisconsin and Harvard, along with a talented team […]
DNMT1-interacting RNAs (DiRs): DIY Methylation for the Locus that has EverythingOctober 18, 2013The holidays are just around the corner, but the gifts are arriving early as a talented crew of epigenetics enthusiasts published some great work in Nature last week that suggests some RNA transcripts have more self control than a Jedi. Look out Luke, these under appreciated RNAs fit DNMT1 like a glove, and block local DNA methylation. […]
