miRNA-Mediated Viral Attenuation Gives Vaccines a Boost

June 7, 2009

With all the recent talk of swine flu and pandemics, you might be wondering how the development of new flu vaccines is coming along. In an example of impeccable timing, researchers at the Mount Sinai School of Medicine now report that they’ve attenuated, two strains of the influenza A virus, the culprit behind swine, avian, […]

Curing Transposable Elements May Sicken Nearby Coding Genes

June 4, 2009

As in many aspects of life, curing the genome of transposable elements (TEs) may be a trade-off. To stop TEs from bouncing all over the genome, cells often resort to small RNA-mediated methylation. But researchers at UC Irvine have discovered that silencing TEs that settle in close to coding regions can reduce the expression of […]

Measuring Nucleosome Dynamics with CATCH-IT

May 25, 2009

When he’s not running his lab up at the Hutch or co-editing epigenetics’ only open source journal, Epigenetics and Chromatin, Dr. Steve Henikoff tinkers a bit (ok…that might be a bit of an understatement). Credited with inventing a range of useful research methods that have streamlined processes from sequencing to computational prediction tools, the Chicago […]

What is Suppressing The Suppressors?: Modified CTCFs linked to silenced tumor suppressors

May 20, 2009

Looking for exotic enzymes to silence tumor suppressor genes? You might be searching in vain. Maybe try looking for heterochromatin instead. Salk Institute postdoc Michael Witcher was baffled by what made p16INK4a not tick in breast cancer cells. He fed the genetic sequence into some prediction software, but it wasn’t much help. So he did […]

miRNA Discovery: Algorithms, Sequencing and Life Outside miRBase

May 12, 2009

Back in the early days, they were these interesting “genes” with names like “lin” and “let” that appeared highly involved in developmental timing, so much so that they were called small temporal RNAs (stRNAs). A lot more has changed in the field of miRNA discovery than naming mechanisms since those early days when the first […]

miRNAs Driving the Evolution of the Regulatory Cockpit

May 8, 2009

Recent discoveries in the field of epigenetics continue to transform the “light switch” examples of gene regulation with which the 30+ crowd was schooled into something a little more complicated…like an airplane cockpit. We’re not talking your average Cessna either, more like an Airbus A380. Evidence from a number of miRNA studies have added them […]

miRNAs Get Well Deserved Promotion

April 30, 2009

Since we launched EpiGenie, we’ve always considered ourselves big promoters of miRNA. Sure, we cover the big headers in chromatin and DNA methylation too, but it’s hard not to identify with these small, overlooked contributors… (OK enough with our high school sports sob stories). Once again we’ve been humbled by Mother Nature as a novel […]

The Ups and Downs of miR-145 and OCT4 in hESCs

April 30, 2009

Human embryonic stem cells (hESCs) are delicate little creatures. Left to their own devices – especially in culture — they want to differentiate or die. By now you’ve probably heard of the intricate network of factors that allow these cells to retain their stemness – some, like the transcription factors OCT4 and SOX2, prevent differentiation […]

Fine-Tuning mRNA Deliveries with Alternative Polyadenylation

April 28, 2009

The US Post Office tried it a few years back when they added those four extra digits onto our zip codes, allowing advertisers to target us with SPAM with utmost precision. At EpiGenie, we too, are always looking for simpler ways to pass along targeted information (RSS feeds, telepathy etc.,) to an ever-increasing population of […]

Polycomb and Trithorax Proteins Dominating the In Crowd

April 23, 2009

At EpiGenie, we do our best to keep up with the latest research trends in the epigenetics scene so we couldn’t help but notice that lately, the Polycomb (PcG) and Trithorax (TrxG) proteins are grabbing more headlines than Octa-Mom. Deservingly so, when you consider the critical role these developmental switchboards play in maintaining expression patterns […]
