Bisulfite Sequencing the “Other” Nucleic Acid: Methylated RNADecember 16, 2008What’s good for the goose is good for the gander, so why shouldn’t bisulfite sequencing be used to study RNA cytosine methylation? Until recently, the harsh reaction conditions required for bisulfite deamination were considered detrimental to RNA stability. However, Matthias Schaefer and colleagues developed an RNA bisulfite sequencing procedure that reproducibly and quantitatively detected cytosine […]
To Code or Not to Code…Is that the Question?December 10, 2008In the past few years, ncRNAs have progressed from interesting anomalies to what some researchers think constitute the majority of the mammalian transcriptome. However, as reviewed by John Mattick and coworkers at the University of Queensland and the Ludwig Institute for Cancer Research (both in Australia), it’s increasingly difficult to distinguish coding from noncoding RNAs […]
Let It SnoDecember 2, 2008It’s December, the time of year when much of the States is blanketed in a frosty mantle of the white stuff. But as recently reported in Molecular Cell, the ACA45 RNA appears to have pulled the ultimate snow job. Nikolaus Rajewsky, Gunter Meister, and colleagues revealed that ACA45, which was previously thought to function exclusively […]
miRNA Fights Cancer-Promoting Histone MethyltransferaseNovember 23, 2008What makes some tumors as gentle as purring kittens and others of the same cancer type as ferocious as saber-toothed tigers? A miRNA (miR-101) was recently shown to take a bite out of cancer by inhibiting the EZH2 histone methyltransferase. The study by Arul Chinnaiyan and co-workers at the University of Michigan Medical School, the […]
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 […]
