Novel Primate- and Tissue Specific miRNAs with Dr Isidore RigoutsosMarch 17, 2015In this interview Dr Isidore Rigoutsos discusses his recent paper ‘Analysis of 13 cell types reveals evidence for the expression of numerous novel primate- and tissue-specific microRNAs‘ published in PNAS, February 2015. This paper shows the presence of many more miRNAs than previously thought and uncovers that the majority of these are in fact, cell-type […]
Our Favorite Findings from the Epigenomic RoadmapMarch 10, 2015For those of you with a keen eye, you’ll have already noticed the mass of Epigenomic Roadmap Studies published in Nature in February. In order to help you navigate this mountain of results we’ve highlighted some of our favorite findings from this collection of papers. Here’s our Top Five Findings: Enhancer-like Elements Take Center Stage in […]
New Rising STARs of Transcriptional ActivationMarch 9, 2015If you can pronounce CRISPR, you know RNA-mediated gene control has been a rising star in synthetic biology. In principle, RNA regulation allows gene circuits to have many more independent control switches than traditional protein transcription factors. CRISPR has turned out to be a great system for RNA-guided gene repression, but it hasn’t been as […]
A cHi-C Way of Capturing Chromatin ConformationMarch 9, 2015Identifying cancer risk loci is like trying to find a key you lost somewhere in your apartment. You know that it’s there and by combining experience with indistinct recollection you can even narrow it down to a few square meters. Now imagine you not only have to find the key but also map all the […]
Gene Expression Comes Full CircRNAMarch 9, 2015Circular RNAs (circRNAs) are a diverse RNA species that regulate gene expression in some funky ways, like functioning as super absorbent miRNA sponges in mammalian cells. However, they also seem to be particularly relevant to the brain. Recent research adds a new function to this ‘outside of the box’ method of regulating gene expression by observing circRNAs […]
Express Yourself with Light-activatable CRISPR-Cas9February 26, 2015Guess what? It seems that blue light has a lot more to offer than just helping with your winter time blues. It could also be just what your transcriptional activation system needs. Synthetic biology has a lot to offer omics beyond genome editing and recent work from multiple groups is putting Cas9 in a different spotlight. CRISPR/Cas9 […]
m6Ajor New Function for MicroRNAs in RNA MethylationFebruary 20, 2015It’s no secret that microRNAs are pretty busy molecules. A single microRNA can regulate the expression of several, maybe even hundreds, of transcripts. If that wasn’t enough, researchers at the Chinese Academy of Sciences, Beijing now add another function to this packed list of duties: the control of m6A RNA methylation, which is emerging as an […]
Getting started with Chromatin Conformation Capture (3C)February 15, 2015The concept of chromatin contact mapping, or determining the three-dimensional structure conformation and interactions of chromatin domains, is now a reality because of Chromatin Conformation Capture (3C) and subsequent methods born out of that approach. Several new 3C-based techniques have emerged, each with particular strengths and applications, but the sheer variety creates a challenge when […]
New Transcriptional Repressors for Pick ‘N’ Mix Synthetic Gene CircuitsFebruary 15, 2015As a kid there was no greater feeling on a weekend shopping trip than being set loose on the Pick ‘N’ Mix, carefully choosing from the wealth of candy to create the perfect selection. Lucky for you synthetic biology promises the same thrill, by providing a selection of ready-to-roll interchangeable parts to choose from allowing […]
Plant Receptor Re-engineered to Hear “Drought!” From a New SignalFebruary 12, 2015Don’t get me wrong, plants have a lot of things going for them. However, as Groot’s fellow Galaxy Guardians can attest, vocabulary isn’t one of them. It can be hard to communicate with plants, even once you figure out their language. Take the plant abscisic acid (ABA) receptor, PYR1, for example. PYR1 communicates via ABA, […]
