Preserving the active chromatin state

If cellular identity is to be maintained, it is important that actively transcribed chromatin stretches remain in a loose configuration as long as these genes are needed. Marc Bühler and his group have uncovered a novel positive feedback loop – crucially involving the histone acetyltransferase Mst2 – which ensures that (transcriptionally active) euchromatin cannot be easily converted into (inactive) heterochromatin. Because some of the players in this feedback loop have been implicated in cancer, these findings are relevant to our understanding of human diseases.

RNA lifespan determination during transcription

Control of RNA lifespan is vital for the proper functioning of our cells. Marc Bühler's group at the Friedrich Miescher Institute for Biomedical Research (FMI) has discovered a novel mechanism determining the fate of RNA in mammalian cells: two proteins involved in RNA interference - Dgcr8 and Drosha - together with a methyltransferase, Mettl3, mark nascent RNAs for degradation as they are transcribed. This mechanism allows RNA transcripts to "remember" the conditions under which they were synthesized.

Investigation of the role of water molecules in protein RNA-recognition

Author: System Administrator - Published At: 2017-05-24 11:52 - (115 Reads)
The Allain lab (ETH Zurich)(external link) together with the Sponer group (CEITEC & Masaryk University, Brno, Czech Republic)(external link) has published a paper describing the role of water molecules in the RNA recognition by the RNA recognition motif (RRM) of the Fox-1 protein, which is a regulator of alternative splicing. Its RRM binds to a hexanucleotide RNA target sequence with high affinity and the structure of this complex was determined previously by the Allain lab using Nuclear Magnetic Resonance Spectroscopy (NMR) (Auweter S.D. et. al., (2006) EMBO Journal)(external link). This structure together with a high-resolution X-ray structure of the unbound RRM revealing bound water molecules provided the starting point for molecular dynamics (MD) simulations to further structurally study the role of water in RNA RRM recognition. Based on the results of the MD analyses two selected water binding sites were subsequently studied by NMR, affinity measurements and free-energy calculations. For one of the sites, which is evolutionarily conserved in RRMs, a quantitative agreement between the computational and experimental approaches was found demonstrating the value of MD analyses to analyze hydration patterns involved in RNA-protein recognition.

Cut the long story short – and stitch it back together
A species of unicellular ciliate has found a special trick to make use of the cellular machinery in seemingly impossible ways. Researchers of the NCCR «RNA & Disease – The Role of RNA Biology in Disease Mechanisms» of the University of Bern have for the first time described a mechanism in detail how so called «junk»-DNA is transcribed before being degraded – and this mechanism is remarkably clever.

Genome Editing: Pressing the «Delete» Button on DNA
Until recently, genomics was a «read-only» science. But scientists led by Rory Johnson at the University of Bern and the Centre for Genomic Regulation in Barcelona, have now developed a tool for quick and easy deletion of DNA in living cells. This software will boost efforts to understand the vast regions of non-coding DNA, or «Dark Matter», in our DNA and may lead to discovery of new disease-causing genes and potential new drugs.

Cell fate regulation by LIN41: activity determined by binding location

Helge Großhans and his group at the Friedrich Miescher Institute for Biomedical Research (FMI) have elucidated the mode of action of the RNA-binding protein and stem cell factor LIN41. In an animal model, they showed that LIN41 silences four specific mRNAs, by two distinct mechanisms. They found that the choice of mechanism is determined by where on the mRNA LIN41 binds. As the proteins whose production LIN41 inhibits are responsible for cell maturation, these new findings could be relevant for future stem cell therapies.

How complex cells originated
Mitochondria are the “power plants” of complex cells. In order to provide the cell with energy they need protein building blocks, which are imported from the outside. Over billions of years the “protein import machines” necessary for this process have developed differently than previously assumed, as biochemists in Bern have discovered. This also casts a new light on the evolution of complex cells.

Mitochondrien sind die «Kraftwerke» komplexer Zellen und versorgen diese mit Energie. Dazu brauchen sie Protein-Bausteine, die von aussen importiert werden.

Dies wirft auch ein neues Licht auf die Evolution komplexer Zellen.

Small RNAs interact with newly synthesized transcripts to silence chromatin

Yukiko Shimada, Fabio Mohn, and Marc Bühler at the FMI elucidated an important mechanistic detail of small RNA mediated chromatin silencing. They showed in fission yeast that the small RNA in the RNA induced silencing complex (RISC) interacts with nascent transcripts and not with complementary DNA to induce heterochromatin formation. In addition, both the transcription rate and transcript processing have an impact on the silencing process.
