Natural Antisense Transcripts within Pseudogenes

October 20, 2012

EpiGenie recently reviewed the epigenetic text Non-Coding RNAs and Epigenetic Regulation of Gene Expression by Kevin Morris. To give you a little taste of the material covered in the book, here is a summary of one of the chapters: Natural Antisense Transcripts within Pseudogenes: An EST Survey by Enrique M. Muro and Miguel A. Andrade-Navarro […]

Epigenetic Regulators (miRNAs, lncRNAs) Get Regulated Epigenetically

October 20, 2012

With Halloween coming up, perhaps it is fitting that the authors of two recent papers describe a “tangled web” of epigenetic regulations. In one paper, researchers suggest that DNA methylation and perhaps other epigenetic modifications disrupt long non-coding RNA (lncRNA) activity. In the other paper, a different team shows that DNAm messes with the miRNA […]

DNA Hypermethylation of CpG Islands Doesn’t Contribute to Cancer Progression?

October 9, 2012

And in another example of turning conventional wisdom on its head, researchers from Scotland report that aberrant DNA hypermethylation of CpG island (CGI) promoters does not contribute to cancer development via silencing. Generally, those genes are already repressed before cancer even starts. Researchers have noticed for a long time that many genes’ CGI promoters are […]

Histone Variant H2A.Z Plays in Active and Repressive Elements

October 9, 2012

In this election season, few people are on the fence about their choice for U.S. president. But histone H2A.Z seemingly votes on both sides of the transcription —hanging out at active regulatory elements and at repressive ones. Researchers in Boston figured out how H2A.Z does this, and it may have to do with the different […]

DNA Methylation Spreads its Wings…Rarely

October 9, 2012

Transposable elements are a common mover and shaker in our genomes. Much like your obnoxious friend that you have to keep close tabs on at dinner parties, they’re usually kept under wraps by fancy host silencing mechanisms like DNA methylation. There’s been some evidence that suggests that the DNA methylation that silences transposable elements can […]

Hypomethylated DNA Repeats Surface in Damaged Hearts

October 9, 2012

Repetition may help the brain learn, but it can be rough on the heart. Researchers in Cambridge, U.K. have found that DNA repeats in damaged hearts are hypomethylated, and that’s associated with increased transcription. In research they published last year, the team did the first whole-genome analysis of differential DNA methylation in so-called “end-stage cardiomyopathic […]

Conserved DNA Methylation Changes from Early Childhood Experiences

October 9, 2012

Our brains might not recall our early years, but increasing evidence supports that our methylomes just might. A few studies have shown that cuddles from mama rats—or a lack thereof—are known to affect their offspring’s long-term health and behavior by changing the brain’s DNA methylation patterns over a large scale. Now, a Canadian research effort […]

New Apps: Interactive Epigenomic Data Browser and DNAm Data Toolkits

October 4, 2012

Apple may have bombed their latest Maps integration, but the Epigenome mapping consortia out there are making it look easy by pumping out datasets by the server full. So it only makes sense that there needs to be robust software to help researchers make sense of it all. Two new papers in Genome Biology offer […]

Webinar: Early Life Determinants of Mental Health – Epigenomic Mechanisms with Dr. Patrick McGowan

October 3, 2012

Dr. Patrick McGowan discusses the impact early-life events can have on our epigenomes in this recorded webinar. This webinar is brought to you with support from Porvair Filtration Group. Check out their line of innovative ChIP kits and reagents at chromatrap.com Abstract Human epidemiological studies and studies of animal models provide many examples by which […]

Webinar: Epigenetics of Autism – The Interface Between Genetic and Environmental Risks with Dr. Janine LaSalle

Dr. Janine LaSalle discusses some of the potential epigenetics mechanisms involved in autism spectrum disorders in this recorded webinar. This webinar is brought to you with support from Porvair Filtration Group. Check out their line of innovative ChIP kits and reagents at chromatrap.com Epigenetics of Autism Autism is an increasingly common disorder of complex etiology, […]
