ncRNAs on the BrainNovember 17, 2008Do you remember the name of your fourth-grade teacher? How about what you had for lunch last Thursday? Highschool Prom date? Yeah, we went stag too, but if you’re having a hard time remebering key events, ncRNAs may be to blame! The human brain expresses high numbers of ncRNAs, and mounting evidence indicates important contributions […]
Chromatin Context Tip(60)s the Transcriptional Balance in ESCsNovember 12, 2008Unfortunately, the KISS principle (‘keep it simple, stupid’) doesn’t apply to chromatin. Although we’d like to think that certain histone modifications are always “good” for gene transcription and others are invariably “bad,” Barbara Panning and co-workers at the University of California San Francisco have found that in embryonic stem cells (ESCs), the transcriptional outcome of […]
Silencing Is in the AirNovember 12, 2008Everywhere you look, be it Science or Nature, US Weekly (OK, not quite), silencing by ncRNAs is making headlines. But the targets and mechanisms of this silencing are not always clear. A recent report by Peter Fraser and co-workers at The Babraham Institute (UK) and several other universities and centers in Japan and Europe has […]
Epigenetic Changes in a Hard-to-Treat Childhood CancerNovember 5, 2008A very difficult-to-treat childhood leukemia may benefit from the discovery of a small but potent epigenetic change that launches the cancer but could potentially be reversed relatively easily, preventing cancer-promoting genes from being turned on. Children with the subtype of acute lymphoblastic leukemia (ALL) known as MLL-AF4 have a cure rate of just under 50 […]
New Method HITS RNA-Protein Interaction SitesNovember 5, 2008DNA, it has turned out, isn’t all it was wound up to be. In recent years we learned that the molecule of life, the discovery of the 20th century, did not-could not-by itself explain the huge differences in complexity between a human and a worm. Forced to look elsewhere, scientists turned to RNA; however, methodological […]
