Take a Look: NCBI Epigenomics Sample BrowserOctober 26, 2010Our friends at the NCBI clued us in to one of their newest free tools that should prove to be a big help to anyone wanting to sort through next-gen sequencing data from epigenomic studies. NCBI’s new Sample Browser, located on its Epigenomics page, lets users search, access and analyze sequencing data from various publicly […]
Comparative Epigenomics Branches OutOctober 19, 2010When you’re comparing epigenomes, it’s easy to miss the forest for the trees. Because the epigenetic “fruit” on each nucleotide can vary with factors like cell type, differentiation state, and the environment, it’s often tricky to spot patterns on the epigenome-wide scale. In a recent Nature Biotechnology commentary, Aleksandar Milosavlijevic of the NIH Epigenomics Roadmap […]
How to Tame the MethylomeOctober 18, 2010So many ways to analyze genomic DNA methylation, so little time (and money). With so many choices available these days it’s not easy to figure out the best method to use for methylome studies. A new survey of two Nature Biotechnology papers by Stephan Beck from the UK’s University College London puts together the vital […]
Who Says Dnmt1 is Only a Maintenance Methyltransferase?October 5, 2010While investigating the in vitro activity of DNA methyltransferases on annealed oligonucleotide substrates, Australian researchers recently found that murine DNA methyltransferase I will quite happily methylate non-CpG sites in DNA bubbles. Jason Ross and Peter Molloy from the CSIRO, in collaboration with Japanese researchers from the Institute for Protein Research in Osaka, observed a high […]
Do Transcription Factors Occupy All their Binding Motifs in the Genome? Not quite.October 4, 2010A British team of researchers recently decided to take closer look at the role of DNA methylation in conserved consensus motifs. Dr. Roger Foo from the Department of Medicine, University of Cambridge was nice enough to share a bit about their approach that recently published in BMC Genomics (Sept 2010) last week. Transcription factors recognise […]
