One-Carbon, One Long Life: Methyl Donors Linked to LongevityNovember 22, 2017While manipulating DNA methylation has taken up most of our lifespans, the manipulation of methyl donors critical to this process may just be the key to making up for the lost time. During one-carbon metabolism, the essential amino acid methionine is metabolized into S-adenosylmethionine (SAM), a methyl donor responsible for DNA and histone methylation. Donation of […]
Visualizing CRISPR-Cas9 Genome Editing: Seeing is Believing!November 22, 2017Many studies have put their faith in CRISPR-Cas9 as a means to edit genes in human embryos, to fight HIV, and to explore epigenetic regulation. However, if you are someone who really needs to see CRISPR-Cas9 in action to believe it, an epic new study has you covered! So, cast away those doubts and qualms, […]
dCas9 Shoots Down Microsatellite Repeat ExpansionNovember 22, 2017Dealing with microsatellite disorders has been as difficult as shooting down actual satellites, but thanks to dCas9 its gotten a lot easier. The CRISPR/Cas9 system has proven to be much more than just a pair of scissors. For instance, CRISPR interference (CRISPRi) uses deactivated Cas9 (dCas9) to create site-specific steric hinderance to perturb gene expression. […]
An endosiRNA Trap Shoots Down the Transposable Element Rebellion of Embryonic DevelopmentNovember 12, 2017During early embryonic development, our genome lets down its DNA methylation defenses and becomes vulnerable to rebellious transposable elements (TEs). However, those rebel scum are quickly met with a barrage of endogenous short interfering RNAs (endosiRNAs), all before they realize even realize that “It’s A Trap!” The mechanism of this cunning tactic employed by our […]
Base Resolution Profiling Details the Intricacies of the m1A RNA ModificationNovember 4, 2017Insurance contracts, loan agreements, and scientific studies; while it’s easy to pretend that we know what´s going on after a quick skim, we often require a detailed interpretation of the complex combinations of letters, numbers, symbols, and accents to gain a fuller comprehension of the matter at hand. In the realm of our epitranscriptomic language, […]
