The Mixed Messages of Bivalent Chromatin

June 14, 2016

Navigating the epigenetic landscape is no easy feat. Clear markings and smooth rides through its canals can quickly give way to a hectic hodgepodge of mixed signals and uncertain routes. A great example is bivalent chromatin, which contains marks of both activation and repression. Characterized by Bernstein et al. in 2006, the most studied bivalent […]

Liquid Biopsies Reveal More than Sequence: The Epigenomics of Circulating Cell-Free DNA

May 6, 2016

Every good captain knows that when your ship is in distress, you send out an SOS. Now, two new papers now leave us wondering if that tactic is borrowed from diseased tissues. Many diseases are characterized by cell death that releases circulating cell-free DNA (cfDNA) into the blood stream, which can now be analyzed in […]

Epigenetic Sequencing Woes Overcome by Services Know-how

March 1, 2015

Sequencing technologies have created a dizzying number of opportunities for epigenetic researchers to explore questions that couldn’t be tackled before. Despite the immense power that sequencing delivers, though, the whole process still isn’t quite as simple as pushing a big red button, and watching the groundbreaking discoveries roll in. Even as sequencing becomes faster, easier, […]

Review: Crosslinking-Immunoprecipitation (CLIP) Methods

February 8, 2015

RNA-protein interactions are key to understanding human health and disease. Crosslinking-immunoprecipitation (CLIP) and related technologies are powerful tools for characterizing these interactions. Since their introduction in 2008 (Licatalosi et al., 2008), CLIP-based approaches have been applied to prominent RNA research fields such as HIV and cancer. Recently, Sebla Kutluay and colleagues used CLIP to characterize […]

Keeping Tabs on Off-Target Effects of Genome Editing

February 5, 2015

While the fashion and music tastes of the late 1980’s was rather questionable, it was a time of historic technological and societal change. Between the breakdown of the Soviet Union and the rise of the global computer network that we now call internet, a small group of researchers succeeded for the first time in generating […]

Cellular Transdifferentiation: Meet the 21st Century Alchemists

February 3, 2015

For centuries, some of the world’s leading scholars worked endlessly with one objective, to turn ordinary metals into gold. Now, scientists of the 21st century are trying their hand at another type of alchemy, turning one cell type into another. This process, known as ‘transdifferentiation’ or ‘direct reprogramming’ can create a potentially limitless source of […]

Bacterial Kryptonite Uncovered in the Biological Dark Matter Mines

January 27, 2015

Public health has a looming, if slow-simmering, crisis. Antibiotics, which revolutionized health care in the 20th century, are losing their punch. Evolution, it turns out, is pretty effective at producing things that don’t die. Accordingly, bacteria are evolving resistance to our antibiotic arsenal, and more people are suffering from previously-treatable infections. Meanwhile, the pipeline of […]

Active Demethylation: TET Enzymes, 5hmC, and Company

January 20, 2015

5hmC was originally discovered way back in the 50’s in bacteriophages and was first observed in mammals in the 70’s, but research into this was set back when these studies failed to replicate. And going back to the future, in 2009 two independent research groups, publishing on the same pages in science, found that this “unknown […]

Plotting the Path to Pluripotency Uncovers Key Role of DNA Methylation

December 29, 2014

If you’ve read our recent piece ‘Reprogramming Roadmap Reveals Fuzzy New Stem Cells‘ you’ll already know how “Project Grandiose” [1, 2], the brainchild of Andras Nagy, identified a new pluripotent state (the F-class stem cell). While the discovery of this new class is thrilling, the main purpose of this grand project was to uncover the […]

Genome Editing Timeline

December 18, 2014

Since its inception, the field of genetic engineering has introduced DNA to plenty of nips, tucks, and modifications all in the name of science. The latest evolution of these, genome editing, might be the most promising. Follow our favorite highlights in this rapidly moving application.
