University of Ulster Online Postgraduate Certificate in Stem Cell BiologyJuly 31, 2012The University of Ulster just wrapped up a successful inaugural year of their Postgraduate Certificate in Stem Cell Biology with 17 students coming on board, 12 of whom have just graduated successfully and another 5 transferring to upgrade to a Postgraduate Diploma.The course is completed fully online by distance learning and will get you up to date […]
DNMTs Determine Radiation Sensitivity of Cancer Stem CellsJune 27, 2012Radiation therapy usually works well against cancer, but some cells that survive the blast can divide and become unstable (cancerous) much later on, causing a relapse. Researchers initially thought that DNA hypomethylation was to blame for “delayed radiation-induced genomic instability,” but a new study in Epigenetics, August 2012 shows that, at least for embryonic stem […]
Enhancers Set the Stage for Stem Cell Differentiation during EmbryogenesisMay 23, 2012It’s amazing to think that we all started out as one cell with DNA from our parents inside. Now, researchers in Spain and the Netherlands say that they have a better idea of how development happens—and enhancers are showing them the way by pointing out active genes. The researchers knew that active enhancers are marked […]
DNA Methylation qPCR Panels Keep Stem Cells in CheckMay 8, 2012Every day, in labs all over the world, stem cells are changing. Sure they may lack (lineage) commitment, but these ultra-promising cellular blank canvases aren’t living sedentary epigenetic lifestyles. DNA methylation in stem cells is on the move with age and passages and you might not even know it. Sequencing still isn’t quite feasible for […]
BrdU Kicks Out DNA Methylation and Kicks Off Stem Cell DifferentiationMarch 7, 2012For many things in life, convenience comes at a cost. Like living in a great city with everything at your doorstep, but the rents are sky-high. A new report says that the use of BrdU, a popular tool for detecting replicating cells (such as neural stem cells in the brain), also comes with a cost, […]
5-hmC Stability a Mixed Bag in Neural Development and AgingJanuary 25, 2012Just like tweets about the U.S. Presidential race, updates on the function of 5-hydroxymethylcytosine (5-hmC) keep pouring in. For a while, no one really knew what the mod did, but new reports find that while some 5-hmC marks are stable, and others are dynamic, both may be critical for neural development right after birth and […]
Born to Lose: Histone Mods Tag Stem Cells for DNA Methylation of miRNA Loci in CancerOctober 12, 2011It’s usually not hard to spot when things seem like they’re destined for failure. Like you ne’er do well cousin, or an American car from the 80’s. Other times, closer examination is required to find the seeds of a problem. That’s what it took for scientists to uncover how some harmless embryonic stem cells (ESCs) […]
EpiGenie Stem Cell Epigenetics ReviewAugust 4, 2011We’re big fans of stem cell research, the vast potential it represents and the close connection it has to epigenetics. Apparently we aren’t alone either, judging by the avalanche of top-notch papers that regularly cross our monitors. We’ve even give serious consideration to launching another site just to be able cover the area properly (StemGenie, […]
Different Strokes For DNA Methylation Patterns in Stem Cell LinesJuly 15, 2011Although we often think of human embryonic stem cell (hESC) lines as being pretty much the same (kind of like the Kardashian sisters), they really are different according to a report by UCLA researchers. Even though they usually can differentiate into the same cell types, hESCs have different methylation patterns—and that may affect gene expression. […]
DNA and Histone H3K9 Methylation Often Work AloneJune 14, 2011Nature is a master of using specific tools for specific jobs, so it’s not too surprising that DNA methylation and SETDB1/H3K9 methylation work on different sets of genes, as University of British Columbia researchers report. But occasionally those tools are more like a Swiss Army knife, like SETDB1, which also methylates H3K9s near endogenous retroviruses […]
