Microfluidic qRT-PCR Unlocks Single Cell miRNA SecretsAugust 12, 2011Recent headlines tell us that the average American lives in a household of 2.62 people, chows down too many potato chips, and thinks that the “Dirty Dancing” remake is a bad idea. But averaging over populations obscures the often highly variable characteristics of individuals, and the same is true for cells. To get a better […]
EpiGenie Stem Cell Epigenetics ReviewAugust 4, 2011We’re big fans of stem cell research, the vast potential it represents and the close connection it has to epigenetics. Apparently we aren’t alone either, judging by the avalanche of top-notch papers that regularly cross our monitors. We’ve even give serious consideration to launching another site just to be able cover the area properly (StemGenie, […]
miR-103 Takes the Sting Out of Chronic PainAugust 3, 2011Simple aches pains send us scrambling for the ibuprofen, so we can only imagine how hard it is to deal with chronic pain. Following up on the role that microRNAs play in some neurological processes, researchers found that miR-103 regulates certain pain channels, and may one day be the a key to chronic pain relief. […]
Regulation of RNA Splicing and Histone Methylation a Two-Way StreetJuly 28, 2011The evidence that chromatin is involved in regulating splicing is piling up. But is that just a one-way street? No, says an international team of researchers who now report loads of data suggesting that splicing can return the favor and contribute to histone methylation. Looking at ChIP experiments in mouse and human genomes, the researchers […]
IsomiRs, 3′ variants May Shine Light on miRNA FunctionJuly 15, 2011As next-generation sequencing continues to explode in popularity, researchers are finding out that nucleic acids are a lot more complex than they ever imagined. One miRNA gene = one miRNA? Nah, that would be too simple. Instead, just like their protein-coding counterparts, miRNA genes can give rise to multiple variants, or isomiRs. Now researchers in […]
EpiGenie Environmental Epigenetics ReviewJuly 6, 2011Thanks to growing interest from the general public, environmental epigenetics is a red-hot topic with no signs of cooling off anytime soon. We’ve certainly covered our fair share of research with an environmental slant to it, so if you want to review, research, or just plain get up to speed on the subject, these articles […]
Hitting the (Hair Dye) Bottle May Alter DNA MethylomeJuly 6, 2011If you change your hair color more frequently than Lady Gaga, you may be affecting your DNA methylation patterns, according to a new study in the journal Epigenetics. To gain a better understanding of the “normal” human methylome, researchers used BeadChip arrays to analyze the methylation of 26,486 CpG loci in the blood of 205 […]
Decoding the Epigenetic Role of Non-coding RNAsMay 18, 2011About 90% of our genome is transcribed, but only 1-2% of the transcripts encode proteins. So what are all of those non-coding RNAs (ncRNAs) doing? A better question might be: what aren’t they doing? In addition to regulating gene expression at the transcriptional and post-transcriptional levels, ncRNAs play a big part in the control of […]
RNA Immunoprecipitation Comes Of AgeMay 17, 2011RNA Immunoprecipitation (RIP) is growing up. After suffering through some awkward adolescent years, RIP has evolved from its humble beginnings in a few hardcore labs and is now stepping out shadow of its more famous cousin, Chromatin Immunoprecipitation (ChIP). The more mature RIP has been steadily building its fan base too with curious researchers seeking […]
miRNAs: Masters of the Tumor MicroenvironmentMay 3, 2011We’ve all heard the slogans about how to lessen our impact on the environment: Reduce, Reuse, Recycle. But, what about the impact of microenvironments on us? Scientists have known for years that tumor growth is supported by the surrounding microenvironment, and now a group of Italian researchers have identified miRNAs as the masters that control […]
