DNA Methylation Addiction Keeps Cancer Cells AliveJune 13, 2012Addictions are so strong that some people think they can’t live without them. For cancer cells, that’s actually the case. Cancer cells’ DNA methylation addiction actually keeps them alive, according to a group of California researchers. Altered DNA methylation is just one of many changes that go down when a cell becomes cancerous. The researchers […]
EZH2, PRC2 Get a Little Guidance From Intronic RNAs to Find Target GenesJune 7, 2012When touring an unfamiliar city or museum, it often helps to have a good guide if you want to see the best sights. Researchers in Spain now report that intronic RNAs, like a well trained herding dog, usher the repressive polycomb complex right to the specific chromatin regions they need to target in order to […]
Epigenetics Book Reviews and Chapter SummariesJune 6, 2012Over the last year EpiGenie has reviewed a couple of the latest epigenetics textbooks for the site. As good citizens of the earth, we of course looked for ways to recycle the books (and the knowledge inside of them) once our writers were done with them. So, we sent our copies out to readers and […]
Variable Methylation Regions and Missing Heritability with Dr. Andrew FeinbergMay 10, 2012Dr. Andrew Feinberg discusses how epigenetics might be related to missing heritability of disease via variable methylation regions. This interview was shot on campus at Johns Hopkins University. Variable Methylation Regions and Missing Heritability So a conundrum in modern human genetics is how epigenetics might be related to missing heritability of disease, what’s commonly […]
HPV Integration Brings Cancerous Changes to the DNA MethylomeMay 9, 2012Vaccination against human papillomavirus (HPV) can protect against many forms of the virus, which can cause cervical cancer. But not everyone gets vaccinated, and there’s still a risk of becoming infected with an HPV type that the vaccination doesn’t cover. Early epigenetic events associated with HPV infection are still mysterious, so researchers in the United […]
Pregnancy-linked miRNA Cluster in Exosomes May Spark AdenomasMay 9, 2012We’ve all had things come back and haunt us—like our high school yearbook picture (the horror!). Now, researchers in Germany say they hypothesize that the same thing could happen with a chromosome 19 miRNA cluster. These miRNAs appear to dampen a mother’s immune response to a developing fetus, but the researchers think that this “immunomodulatory” […]
Colon Cancer Signs on the Dotted Line with Epigenomic Enhancer SignatureApril 16, 2012Handwriting experts say that someone’s signature reveals a lot about their personality. Whether these analyses are “scientific” is debatable, but researchers in Ohio and New Hampshire have evidence that they’ve identified a signature of enhancer histone modifications that points to colon cancer. Mono- and dimethylated H3K4 marks many classes of enhancers, so the team did […]
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, […]
Valproic Acid Derivatives and Cisplatin: Better TogetherJanuary 10, 2012Like PB&J or Brangelina, some things are just better together. Now a new study suggests that combining derivatives of the histone deacetylase (HDAC) inhibitor valproic acid with the chemotherapy drug cisplatin may kill human lung cancer cells better than either drug alone. HDAC inhibitors such as valproic acid show great promise as treatments for a […]
EpiGenie Review: Non-coding RNAs and miRNAs in CancerDecember 9, 2011Based on the latest research, the cancer::non-coding RNA conncection is undeniable. It’s just all the specifics around things like miRNA regulation that are still left to be understood. While dedicated epigenetics investigators are hard at work solving those mechanistic riddles, we’ve decided to take a look back at what’s been learned so far. Here are […]
