Astrocyte microRNAs Welcome Metastatic Cancer Cells to the BrainNovember 12, 2015If asked what to bring on a fishing trip in winter, your answer probably wouldn’t be a bathing suit and sunblock. Likewise, when cancer cells metastasize, they need the right equipment to reside in unfamiliar organs; in other words, they must adapt their expression programs to accommodate their new microenvironment. How they do this is […]
Sperm miRNA Drives Intergenerational Stress ResponseOctober 30, 2015Stress is something that we’re all too familiar with, but its impact across generations has remained controversial. The distinction between intergenerational effect and transgenerational inheritance is particularly important to understand the differences between a direct effect on exposed gametes or indirect transmission to unexposed gametes. However, the molecular mechanisms behind both phenomena have received much […]
Small Molecule Targeting RNA Heralds Comeback for Antibiotic DiscoveryOctober 23, 2015Although many readers may have been excited about the release of the new Prince album last month, the biggest comeback story of this year was over at Nature. The antibiotic field has reported only covers or remixes since the 1980s, but now researchers from Merck pharmaceuticals have discovered a potential new antibiotic that works by […]
MicroRNA Isoforms Distinguish Between Breast Cancer SubtypesOctober 6, 2015Much like the early explorers who set out to find a new trade route to Asia and accidentally stumbled across the Americas, researchers mapping the transcriptome have come across some big surprises. Recently, Isidore Rigoutsos’s lab showed that the expression of microRNA isoforms (called ‘isomiRs’) and tRNAs depends on sex, population, and race. Now, this […]
CombiGEM Takes Combinatorial miRNA Analysis to the Next LevelSeptember 7, 2015Single gene-focused research can sometimes be like the Indian story of the blind men and the elephant. The blind men, having never seen an elephant before, decide to touch one and feel it for themselves, to determine its shape. However, since they all grab different parts of the elephant, each can only describe what they feel, […]
DNA Methyltransferase Teams Up with Long Non-Coding RNA to Police Colon Cancer CellsSeptember 5, 2015Mulder and Scully. Holmes and Watson. If TV and books are anything to go by, then unconventional pairings between the hot-headed detective and their calm and collected partner get results. Now it seems that another unlikely duo work together in the fight against crime of a biological nature. A new study reports that a DNA […]
Race, Gender and Non-Coding RNA: tRNAs Don’t Play it Politically CorrectJuly 17, 2015Human genetics just got a whole lot more complicated with a report published last week by Isidore Rigoutsos’ team in Oncotarget. As if differences in expression profiles between cells, tissues and differentiation stages weren’t already enough, it seems that race and gender also affect genomic output. Specifically, the team focused on transfer RNAs (tRNAs). tRNAs […]
CRISPR-Display: For the lncRNA Enthusiast that has EverythingJuly 6, 2015From wall hung TVs to the latest wearable; displays have been a key technology differentiator for years. Now we’d like to introduce you to CRISPR-Display, one of the latest applications of CRISPR technology for the lncRNA lover that wants to elevate their functional game. Interest in lncRNAs continues to surge, but like other uncharted areas […]
miRNA-Switches Makes Stem Cell Selection Pure and SimpleMay 28, 2015As any sports coach, hopeful lottery winner, or child in a candy store will tell you, an effective selection strategy is vitally important to a successful outcome. Selection is also an important concept for scientists and clinicians hoping to take advantage of the ability that human pluripotent stem cells (hPSCs) have to differentiate into multiple […]
Get in the Loop of Antisense Mediated Transcriptional RegulationApril 30, 2015Long non-coding RNA research isn’t just a load of HOTAIR; since their initial discovery long non-coding RNAs have revealed their importance in regulating the genome. One such insight is the observation that lncRNA express antisense transcripts, which are abundantly found either partially or completely overlapping with transcripts from the opposite strand. These have been shown […]
