7th & 8th Bases Found On the Road to DemethylationJuly 25, 2011Just how many DNA bases can there possibly be? It was a pretty big deal when the 6th base, 5-hydroxymethylcytosine (5-hmC) was found in 2009, and now the same University of North Carolina team has discovered two more cytosine analogs to bring the total to eight…for now. In the uproar over 5-hmC, researchers were sent […]
ENCODE and Roadmap Epigenomics Antibody Validation DatabaseJuly 19, 2011Many epigenetics techniques and projects rely on high-quality antibodies, but not all commercial antibodies perform well enough to get the job done. On top of that, there’s no uniform standard, or easy steps to fully validate a good antibody. With help of the Park lab at Harvard Medical School, there is now a place that […]
DNA Methylation Shifts in Early Immune DevelopmentJuly 19, 2011How can you know if something’s changed, if you didn’t see what it looked like to start with? That was the idea behind a new study that profiled DNA methylation in the immune development of youngsters. With more and more focus on environmental causes of immune diseases, and their epigenetic links, Australian researchers decided to […]
Different Strokes For DNA Methylation Patterns in Stem Cell LinesJuly 15, 2011Although we often think of human embryonic stem cell (hESC) lines as being pretty much the same (kind of like the Kardashian sisters), they really are different according to a report by UCLA researchers. Even though they usually can differentiate into the same cell types, hESCs have different methylation patterns—and that may affect gene expression. […]
IsomiRs, 3′ variants May Shine Light on miRNA FunctionJuly 15, 2011As next-generation sequencing continues to explode in popularity, researchers are finding out that nucleic acids are a lot more complex than they ever imagined. One miRNA gene = one miRNA? Nah, that would be too simple. Instead, just like their protein-coding counterparts, miRNA genes can give rise to multiple variants, or isomiRs. Now researchers in […]
