LNA miR-122 Inhibitors Put HCV in Lockdown in vivoDecember 3, 2009miR-122 is a talented regulator. Sure it can negatively regulate gene expression by binding 3’ UTRs of target mRNAs, but it’s also shown that it can bind 5’ UTRs in the HCV genome just as well, and act as a positive regulator, giving the virus a hand with replicating its genome. Facilitating viral replication? Well, […]
Pre-miRNA Importin and Exportin Strong As EverDecember 2, 2009In today’s global economy, imports and exports can ebb and flow dramatically depending on economic conditions. But in the fine-tuned cellular economy, where supply-demand runs the show, miRNA Importin and Exportin operate with consistency that would have most economists envious. When pre-miRNAs are shipped from the nucleus to the cytoplasm. Exportin-5 escorts the ~65 nt […]
ChIPing Away at Small Samples with Direct SequencingDecember 1, 2009One rarely hears mention of deep sequencing without “more” being dropped into the sentence. More coverage, more depth,…more sample? That’s right. As valuable as next generation sequencing platforms have become, those library construction protocols demand a fair amount of sample. Often more than can be coaxed out of a biopsy, or other small cell population. […]
Bulletproof Your Bisulfite Conversion: Key Considerations from the ExpertsDecember 1, 2009There’s a lot of talk out there about bisulfite conversion, how useful it is, how it’s the “Gold Standard,” how laborious it is, how rough it is on your samples, but the reality of it is that there probably isn’t any better way to prep your samples for single nucleotide resolution methylation profiling, so don’t […]
Got miR-2861? Novel miRNA Is Linked to OsteoporosisNovember 18, 2009What can you do to keep your bones healthy and strong? In addition to sporting the ever-trendy milk mustache, you might want to avoid mutations in miR-2861, a newly discovered miRNA involved in osteoblast differentiation. A team of Chinese researchers identified miR-2861 by cloning miRNAs from primary mouse osteoblasts (the cells responsible for bone formation). […]
