Just when it seems that scientists are winning the fight against cancer, tumors hit below the belt by developing resistance to chemotherapies. But researchers at the University of Glasgow and TopoTarget Prolifix Ltd. have shown that delivering a 1-2 punch of epigenetic drugs could allow the chemotherapeutic agent cisplatin to knock out resistant tumors. Cisplatin, […]
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.
The lab gloves came off in a recent Nature exchange on the putative role of the transcriptional repressor, REST, in embryonic stem cell pluripotency. In the left corner, Singh and colleagues, conducting experiments out of MD Anderson in the Lone Star State, published data in Nature back in May, 2008 indicating that REST may control […]
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 […]
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, […]
