We often wonder what is in the top chromatin researchers iPod playlists. What gets them through those late night, seemingly countless ChIP assays. Although we hope Vanilla Ice’s “Ice Ice Baby,” or Young MC’s “Bust a Move,” are represented, we know each of us has our own Greatest Hits. Recently, a team at Johns Hopkins […]

Chromatin Maps Conserved Missing linc-RNA
Researchers in Boston figured that maybe they could find something interesting in all the non-protein, non-miRNA, non-siRNA genes. They did…linc-RNAs. Through a massive sequencing of ChIP data they uncovered a chromatin “signature” for actively transcribed regions between known protein coding genes, and used this signature to identify about 1700 previously un-annotated stretches of the genome at […]
Summitting With PeakSeq.It’s About Mappability
ChIP-seq continues to assault bioinformatics teams with avalanches of data, but the upside of using this powerful approach brings some challenges along with it. Modeling background accurately requires a few tweaks, so before you get all excited about the double black diamond peaks that you’re seeing in regulatory motifs, you might want to factor in […]
Susan Clark: Leading Ladies in Epigenetics Research
A native of Australia, Susan J. Clark obtained her PhD in 1982 from the University of Adelaide. For the next 8 years, Dr. Clark worked in the biotech industry before returning to basic research where she was instrumental in developing the bisulphite sequencing method for DNA methylation analysis in the early 90s. Dr. Clark is […]
DNA Methylation Detection Goes Small Time
A sensitive new nanotechnology assay might represent a “quantum leap” in DNA methylation detection. The technique, which was developed by Vasudev Bailey and co-workers at The Johns Hopkins University School of Medicine, uses quantum dots-fluorescent nanocrystals of a semiconductor material-to selectivel detect and quantify minute amounts of methylated DNA. As in methylation-specific PCR (MSP), sample […]
