Twins Team Up to Help Unravel DNA Methylation in SchizophreniaMay 12, 2015While they can’t see through lead or stop bullets with their chest, twins do have a superpower of their own – when it comes to unraveling the complex genomic and epigenomic changes underlying diseases and disorders. In their latest adventure monozygotic twins are helping to understand the DNA methylation changes associated with schizophrenia. The epigenomics of […]
A TET-à-TET Between SIRT6 and 5hmC Controls Embryonic Stem Cell FateMay 12, 2015With many political parties fighting it out for influence in the UK general election last week, it is nice to see the spirit of cooperation alive and well in embryonic stem cells. In their latest study, Raul Mostoslavsky and colleagues show that two giants of epigenetic regulation, histone acetylation and DNA hydroxymethylation, team up to […]
6mA Makes the Grade as a Eukaryotic Epigenetic MarkMay 12, 2015There’s no denying that we love DNA methylation, so we are delighted to learn of another form of DNA methylation that has come on the scene as an epigenetic mark. N6-Methyladenosine (6mA or m6A) refers to the methylation of adenosine at its nitrogen-6 position, as opposed to 5mC and related oxidative marks (5hmC, 5fC, 5caC) that occur on […]
Upcycling the Epigenome in the Brain Help Neurons Stay in TouchMay 5, 2015Upcycling is the latest of many green crazes where people keep hold of old furniture and instead of throwing it away, they repurpose it to give new life. It seems that the brain might be doing the same for methylation. It’s been a long held belief that DNA methylation is fixed in differentiated cells, yet there is […]
None Shall Pass! Genome Editing Stops Heritable Diseases in Their TracksMay 4, 2015The scientific world is still reeling from the news of the first genome editing of human embryos to treat genetic disease, as we have reported previously here on Epigenie. Unfortunately, the paper suggested that this strategy may need huge improvement or may never be applicable. However, another recently published study, from the laboratory of Juan Carlos […]
Spray Your Way Free of Cystic Fibrosis with a Gene Editing Nasal SprayMay 1, 2015With allergy season around the corner, you might be turning to nasal sprays to relieve the symptoms. But now Marie Egan’s lab at Yale University have developed a very different type of nasal spray that helps overcome a disorder much more devastating: Cystic Fibrosis. Earlier attempts to correct the F508del CFTR mutation have been undertaken using CRISPRs in […]
Catching RNA Polymerases in Action: New NETs for Higher ResolutionMay 1, 2015For a long time RNA polymerases did not get the credit they actually deserve. They have been viewed as muscle-cars at a drag race: Waiting for a start signal to race along the gene only stopping for the finish line. This view, however, has markedly changed with the development of high-throughput sequencing techniques such as […]
Cas9 Gets an Illuminating Upgrade: Light-activatable Genome EditingApril 30, 2015While dead Cas9 (dCas9) has been coupled to optogenetic systems to enable on the fly effector domain action, the not so dead Cas9 has just gotten a very different form of light induction that works with genome editing. The designer genome editing system, developed by a talented team from the University of Pittsburgh and the University of North Carolina at Chapel Hill, […]
Get in the Loop of Antisense Mediated Transcriptional RegulationApril 30, 2015Long non-coding RNA research isn’t just a load of HOTAIR; since their initial discovery long non-coding RNAs have revealed their importance in regulating the genome. One such insight is the observation that lncRNA express antisense transcripts, which are abundantly found either partially or completely overlapping with transcripts from the opposite strand. These have been shown […]
Finding Epimutations in the Genome HaystackApril 30, 2015Trying to identify DNA methylation mutations with current technologies usually requires a lot of cells, making it a lot like hunting for a needle in a haystack. Getting down to looking at single cells is becoming possible, but requires you to look at the whole genome, making the hunt for epimutations difficult. Recent work from Silvia […]
