Astrocyte microRNAs Welcome Metastatic Cancer Cells to the BrainNovember 12, 2015If asked what to bring on a fishing trip in winter, your answer probably wouldn’t be a bathing suit and sunblock. Likewise, when cancer cells metastasize, they need the right equipment to reside in unfamiliar organs; in other words, they must adapt their expression programs to accommodate their new microenvironment. How they do this is […]
Resistance is Futile: Epigenetic Therapy Makes Cancer Cells DefenselessJuly 9, 2015A team of American scientists have shown that an epigenetic therapy might hold promise for combatting drug resistance in cancer. Cancer cells are masters of drug evasion and adept at using alternative pathways to give them an edge during treatment, complicating many therapeutic approaches. Overcoming drug resistance in cancer cells, would save millions of lives […]
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 […]
Our Favorite Findings from the Epigenomic RoadmapMarch 10, 2015For those of you with a keen eye, you’ll have already noticed the mass of Epigenomic Roadmap Studies published in Nature in February. In order to help you navigate this mountain of results we’ve highlighted some of our favorite findings from this collection of papers. Here’s our Top Five Findings: Enhancer-like Elements Take Center Stage in […]
A cHi-C Way of Capturing Chromatin ConformationMarch 9, 2015Identifying cancer risk loci is like trying to find a key you lost somewhere in your apartment. You know that it’s there and by combining experience with indistinct recollection you can even narrow it down to a few square meters. Now imagine you not only have to find the key but also map all the […]
Active Demethylation: TET Enzymes, 5hmC, and CompanyJanuary 20, 20155hmC 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 […]
Unwinding the Chromatin–Cancer ConnectionDecember 4, 2014There’s no denying that epigenetics and cancer are intimately intertwined, and that untangling this connection is vitally important in expanding our understanding of cancer initiation and development. Epigenetic signals are reversible regulators of gene expression and as such, make compelling targets in the study and treatment of cancer. As high-throughput data analysis becomes the norm, entire panels […]
Embryonic Stem Cell Model Highlights Importance of Histone Mutation in Childhood TumorigenesisNovember 26, 2014Childhood cancers are truly devastating diseases; they cause major loss of young lives due to the distinct lack of treatment options stemming from the limited access to tumor tissues. Hopefully, a promising new study published in Science will change this. Researchers from the laboratory Viviane Tabar at the Memorial Sloan-Kettering Cancer Center, New York, USA […]
Are LncRNAs the Future of Non-Invasive Prostate Cancer Testing?October 9, 2014Prostate cancer is the leading cause of mortality in North-American men and as a result many are forced to the clinic for some rather invasive biopsies, but thanks to some cool epigenetics involving lncRNAs, those once dreaded trips to the doctor’s office may soon be replaced a much less invasive urine test. Ranjan Perera and crew […]
Tumors Go Minimalist with DNA Methylation BlocksAugust 26, 2014It seems that cancer is joining the minimalist trend, and has recently been caught sporting a universal and distinct DNA methylation signature. A talented team from John Hopkins lead by epi-gurus Andrew Feinberg and Rafael Irizarry show that large hypomethylated blocks are a defining feature in a number of different human solid tumors. These hypomethylated blocks also […]
