We’re all asking ourselves these days, “But who regulates the regulators?” For miRNA, the answer may just be a consortium of genes both living and dead. A group of Toronto researchers exogenously expressed versican 3’UTR (a potential target for miR-199a*) hooked up to a reporter construct. While expression of the luciferase or GFP reporter was […]
Ever get that feeling that you forgot something? Well maybe you did, but it doesn't have to be recent epigenetics research if you scope out our Headlines each week.
As crafty as its animal namesake, the cell-type-specific RNA splicing regulator FOX2 slips in and out of the transcriptome, causing the inclusion of one exon here or the exclusion of another there, with no apparent rhyme or reason. However, researchers at the Salk Institute and the University of California, San Diego recently outsmarted FOX2 by […]
To methylate, or not to methylate? That is the question. Whether ’tis nobler in the genome to suffer the onslaughts and diversions of oncogenic DNA viruses or, by inactivating, disguise them (from immune surveillance). When researchers used bisulfite sequencing to examine the methylomes of three double-stranded DNA viruses (Human Papilloma Viruses (HPV) 16 and 18, […]
Did your behavior at the lab holiday party elicit whispered comments, furtive glances, and snide snickers from co-workers the next day? Although we don’t know exactly what possessed you to dance on the boss’s coffee table wearing your DNA necktie as a headband, researchers have shown that some physiological and pathological behaviors result from epigenetic […]
February 17th, 2009. Even in evolution there can be too much of a good thing. What if a transposon broke free and replicated whenever it wanted to, and integrated wherever it wanted to, unchecked? How long would the host be around? Such may have happened to Alu repeats in primates about 40 million years ago. […]
