Validating GWAS with Epigenome EditingOctober 10, 2015GWASs (genome-wide association studies) have found a lot of genetic variants associated with various traits and diseases. But GWASs suffer from that old weakness, the mantra of every good scientist: correlation does not imply causation. The problem gets even worse when you find out most GWAS variants are in non-coding regions of DNA, meaning they […]
New Reporter System Captures DNA Methylation in Real TimeOctober 1, 2015If a picture is worth a thousand words then surely a video must be worth more? So far, our knowledge about DNA methylation has been limited to a comic strip of static images at different stages. That may all be about to change with a new tool reported by the lab of Rudolf Jaenisch, which […]
A Polymerase Evolved for Your Bisulfite Converted DNASeptember 11, 2015Bisulfite conversion can be used in so many different applications that it’s not so surprisingly referred to as the gold standard for DNA methylation analysis. But getting to the gold can create some problems for DNA. The process of converting methylated DNA (5mC) to Uracil and then finally a Thymine is harsh as it involves […]
DNA Methyltransferase Teams Up with Long Non-Coding RNA to Police Colon Cancer CellsSeptember 5, 2015Mulder and Scully. Holmes and Watson. If TV and books are anything to go by, then unconventional pairings between the hot-headed detective and their calm and collected partner get results. Now it seems that another unlikely duo work together in the fight against crime of a biological nature. A new study reports that a DNA […]
New Insights into Puzzling Placental DNA Methylation DomainsAugust 14, 2015The human placental methylome was the first normal tissue where partially methylated domains (PMDs) were characterized, found to be developmentally dynamic, and distinct from highly methylated domains (HMDs, methylation >70%). PMDs are a large scale genomic feature with DNA methylation levels that are less than 70% but nowhere near 0% and tend to harbour neuron […]
