Context Is Key for miRNA Target SitesNovember 4, 2009If your boss were to tell you that you’re acting like a real ass, you’d probably start packing your desk, unless you’re auditioning for Eeyore in that upcoming Winnie the Pooh play in which case you’d be stoked. So much in life is all about the context…and miRNA regulation is no exception. A recent report […]
miRNA Target Prediction Program Round-upOctober 21, 2009As miRNA discovery continues to skyrocket, the obvious question is: What are these miRNAs targeting? Lately, that topic seems to be as hot as any “Jon & Kate Plus 8” gossip. Several programs have been created to get at that question, and predict targets for miRNAs, but it’s hard to know which ones are really […]
How Low Can They Go: Unusually Small RNAOctober 21, 2009Let’s all do the ncRNA limbo! They may not be as festive as the dance at the office holiday party, but non-coding RNAs are really getting down…in size anyway! It seems every few months, we’re learning about a new class of RNAs that’s even shorter than before. Recent work from Bino John’s group at the […]
Non-Coding (RNA) Doesn’t Have to Mean Non-SenseOctober 14, 2009Our understanding of non-coding RNAs has ramped up like a quarter pipe at the X Games over the last several years and, if recent publications are any indication, we’ve only scratched the surface. The realization that just a sliver of our vast transcriptomes is protein-coding, much of it is churned out in both directions, and […]
The Emerging Players in the Epigenetics of HypoxiaOctober 14, 2009Even beyond its most obvious consequence – death — oxygen deprivation has profound effects on cells and tissues. A couple of recent papers highlight some connections between epigenetics and hypoxia. Anaerobic respiration is great for brewing beer. But add O2 and the yeasty beasties stop fermenting. It’s the same principle – only in reverse – […]
Putting Epigenetics on the MapOctober 12, 2009Between the mapping centers, generating enormous quantities of data for the NIH Roadmap Epigenomics Initiative, and the NCBI that is archiving and distributing it, lies the Epigenomics Data Analysis and Coordination Center. Aleksandar Milosavljevic and co-PI Arthur Beaudet won the 5-year, $7+ million U01 grant last year to set up and run the EDACC informatics […]
Small RNA Sequencing Adds Color(Space) to miRNA Dynamics in Stem Cell RegulationOctober 1, 2009For the last few years, stem cell researchers have been intrigued by miRNAs’ Houdini-esqe disappearing act as stem cells embrace their fate. Add in evidence showing how knocking out endogenous miRNA machinery like Ago2 can really add a few kinks to proper neural development and you get a stem cell community that’s fired up to […]
miRNA Regulatory Documentary Bonus Footage: Featuring XRN-2September 10, 2009Most miRNA plots we follow share a similar climactic ending: miRNA inhibits this, in this condition, in response to this. Don’t get us wrong. We can read about miRNA regulation all day, which is good because we often do, but do you ever wonder what happens to miRNAs after they’ve locked their target, and put […]
Getting RIPped: miRNA Target ID Workout DeliversSeptember 9, 2009As former bodybuilder turned California Governator, Arnold Schwarzenegger, once said, “Great abs are made in the kitchen…” That may be, but when it comes to epigenetics research, great abs are made by great labs and suppliers, and they’re put to work in immunoprecipitation applications like RIP Chip. Recently, Anke van den Berg and colleagues at […]
Rinse and Spit: The Future of Cancer TestingAugust 25, 2009Gather round the spittoon, partners, there’s a new Ome in town. The miRome has joined the proteome and transcriptome as the “third diagnostic alphabet in saliva,” extols UCLA dental prof David Wong. For the past seven years or so the NIH (in particular the National Institute of Dental and CranioFacial Research) has been pushing saliva […]
