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.

Ein DNA-Pantoffelheld
Pantoffeltierchen haben einen ganz besonderen Trick entwickelt, um die Zellmaschinerie auch in scheinbar unmöglichen Situationen noch nutzen zu können. Forschende des Nationalen Forschungsschwerpunkts «RNA & Disease – Die Rolle von RNS in Krankheitsmechanismen» von der Universität Bern haben zum ersten Mal einen Mechanismus beschrieben, wie «Junk»-DNA noch ausgelesen statt gleich abgebaut wird – und dieser ist von erstaunlicher Raffinesse.

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.

Ein «Delete-Knopf» für die DNA
Forschende unter der Leitung des Molekularbiologen Rory Johnson der Universität Bern haben eine Software entwickelt, mit der Teile der menschlichen DNA rasch und einfach aus lebenden Zellen gelöscht werden können. Die Software wird zu einem besseren Verständnis der «Dunklen Materie» unserer DNA führen, der sogenannten nicht-codierenden DNA, und könnte die Suche nach krankheitsverursachenden Genen sowie neuen Therapien erleichtern.

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.

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.

Forscher finden «Krebssignatur» in Proteinen
Das Team von Prof. Mihaela Zavolan vom Biozentrum der Universität Basel hat die Herstellung ribosomaler Proteine in unterschiedlichsten Geweben untersucht und entdeckt, dass verschiedene Krebsarten eine spezifische «Signatur» aufweisen. Wie die Forscher in «Genome Biology» berichten, eignet sich diese «Krebssignatur» auch zur Prognose des Krankheitsverlaufs.

The team led by Prof. Mihaela Zavolan at the Biozentrum, University of Basel, has investigated the expression of ribosomal proteins in a wide range of human tissues including tumors, and discovered a cancer type specific “signature“. As the researchers report in “Genome Biology“, this “cancer signature” could potentially be used to predict the progression of the disease.

New Insights into NMD

Author: System Administrator - Published At: 2016-11-29 15:25 - (445 Reads)


The Mühlemann lab of the University of Bern published a high-confidence set of endogenous transcripts that are targeted by nonsense-mediated mRNA decay (NMD) in HeLa cells. These NMD targets were identified by conducting a meta-analysis of transcript level changes under knockdown and rescue conditions of three NMD factors (UPF1, SMG6 and SMG7) followed by high throughput transcriptome sequencing at the NGS technology platform in Bern. This study revealed that the SMG6 and SMG7 degradation pathways are highly redundant regarding the RNAs they target. Moreover, it identified a substantial fraction of transcripts annotated as “non-coding” in the database as NMD substrates, indicating that in fact they are translated. The authors also confirmed that introns located more than 50 nucleotides downstream of the stop codon, upstream ORFs and long 3’ UTRs are features enriched among NMD targets.

Erkältungsviren haben ihren Ursprung in Kamelen – genau wie MERS

Vier menschliche Coronaviren sind auf der ganzen Welt verbreitet und neben den bekannteren Rhinoviren verantwortlich für Erkältungen. Meist verlaufen diese Infektionen für den Menschen harmlos. Für eines der vier menschlichen Erkältungs-Coronaviren «HCoV-229E» haben Virologen aus Bern und Bonn nun den Ursprung gefunden – es stammt ebenso aus Kamelen wie das gefürchtete MERS-Virus.

Genetischer Code: «Stop» heisst nicht immer «Stop» / Genetic code: Stop does not always mean stop

Bisher galt der genetische Code, mit dem Erbinformationen vermittelt werden, seit der Entstehung des Lebens als unverändert. Nun haben Berner Zellbiologen in Wimpertierchen einen Baustein der genetischen Kommunikation entdeckt, bei dem mehrere «Interpretationsmöglichkeiten» bestehen. Darin zeigt sich ein bisher unbekanntes Zwischenstadium der Evolution.

The genetic code is believed to be strongly conserved through evolution – from the earliest bacteria until today. But researchers from the Institute of Cell Biology of the University of Bern have now found two ciliate species where nature probably can be seen experimenting with the meaning of a codon, the building blocks of genetic communication.

Genetic Codes with No Dedicated Stop Codon: Context-Dependent Translation Termination

The group of Prof. Mariusz Nowacki at University of Bern discovered new genetic codes in which surprisingly all 64 codons encode standard amino acids. In the current issue of Cell, Nowacki et. al. provide evidence for a role of mRNA 3’ ends in distinguishing stop from sense in the ambiguous ciliate “stop” codons. In the proposed model, translation is the default recognition mode for “stop” codons, while termination occurs via context-specific influences located in the 3’ends of transcripts. The authors suggest that competition between tRNAs and eRF1, which is affected by the proximity of poly (A)-binding proteins (PABPs), decides over translation or termination at ambiguous “stop” codons.
