Now that has spring has sprung, many of us are quickly remembering not only how much we missed the sunshine, but also that we forgot to stock up on aloe vera to soothe that fresh sunburn. Attesting to the utility of a good spot treatment, the lab of Yang Shi at Harvard Medical School reveals […]

m6A Enables XIST’s Repressive Existence
Life can be hard out there for an X chromosome, particularly when faced with a well-known molecular form of sexual discrimination. The key to this repressive environment and resulting existential crisis is X-inactive specific transcript (XIST), a long non-coding (lnc)RNA known to undergo modifications such as cytosine methylation. However, RNA methylation is a rapidly evolving […]
m6A Modification Protects Against Heat Shock
When exposed to high temperatures, cells behave much as we would on a hot summer’s day. Cell division, and most energy-consuming activities, come to a standstill (a bit like the human equivalent of lying perfectly still on a sunbed with a mojito in hand). Yet, despite the general repression of translation, genes encoding protective heat […]
In the Epitranscriptome Clusters of Co-Methylation Define m6A’s Function
Lately, at the EpiGenie HQ, we’ve had our mind on methylation and our money on RNA. Not just limited to DNA or Cytosine, we’ve seen that N6-methyladenosine (m6A) is a highly dynamic mark in RNA that has a critical role in stem cell differentiation. Now researchers from the Northwestern Polytechnical University in China have set out to find how m6A dynamics work on […]
m6A RNA Methylation Modifications Helps Cells to Forget Stem Cell Past
When it comes to post-translational modifications, it’s fair to say that DNA and proteins have taken most of the limelight in epigenetics. RNA modifications have been largely relegated to the role of supporting actor. Not content with nucleosomes taking all the credit, a team of Stanford and Harvard researchers now demonstrate the importance of RNA […]
