Pre-miRNA Importin and Exportin Strong As Ever

December 2, 2009

In 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 Sequencing

December 1, 2009

One 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 Experts

December 1, 2009

There’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 Osteoporosis

November 18, 2009

What 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). […]

Sopping Up Regulatory Insights with miRNA Sponges

November 17, 2009

We’ve all seen those household cleaning commercials on the tele that show a super detergent that cuts through grease, whitens whites, and zaps pet odor effortlessly, so when we first got wind of miRNA sponges a few years back (Nature Methods, August 2007), we remember being interested but skeptical. But, if these vector-driven miRNA inhibitors […]

MBD-Sequencing: The Latest Methylation Analysis Cocktail Delivers

November 17, 2009

Add 1 part enriched methylated DNA to 2 parts sequencing lanes, and you have a cocktail that delivers key insights without a data hangover. Last week, a team of Ohio scientists added the latest research recipe that is destined to become a lab fav in Nucleic Acids Research. The crew took the benefits of methylation […]

Stressing Out Over Methylation

November 11, 2009

Traumatic events like getting picked last for Dodgeball in gym class can really mess with your head. And some previous research has shown that really devastating incidents, such as 9-11, can change us, even while still in the womb, as shown in this video clip we posted a while back from the PBS Ghost in […]

The Dark-side of Being a Regulatory Star: miRNA Labeling and Manipulation

November 11, 2009

It wasn’t that long ago when cellular miRNAs lived under the radar. They went to work on their targets each day and hung out with other members of the extended RISC family. Their small size and lack of poly-A tails may have kept them out of the spotlight for decades, but the last few years […]

Comparing Long ncRNAs lincRNAs

November 11, 2009

Despite all of the attention to the non-coding transcriptome lately, our knowledge about what most long intergenic non-coding RNA (lncRNA) transcripts do – if indeed they do anything at all, still has more holes than a Dunkin’ Donut shop. Luckily there are folks out there willing to step in to take on the dirty job […]

Epigenetic Drugs: More Than Hype in the Pipeline

November 5, 2009

It’s 10 p.m. on a Friday night, and you’re still stuck in the lab doing ChIP assays. As the piercing whine of the sonicator frays your last nerve, you ask yourself again, “Why did I go into epigenetics research…why couldn’t I have chosen something simpler and more straightforward (like rocket science)?” At times like these, […]
