Hunt for human genes involved in cell division under way

13.07.2005


A systematic search through human genes has begun at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany. Working within the MitoCheck consortium that includes 10 other institutes throughout Europe, the EMBL scientists will silence all human genes, one-by-one, to find those involved in cell division (mitosis) and to answer fundamental questions of how cell division is regulated.



The scientists will use a method called ‘RNA interference (RNAi)’ where chemically synthesized RNA molecules are used to target and silence each human gene. About 22,000 genes will be suppressed and their impact on cell division monitored by live cell microscopy to understand each gene’s role in cell division.

“To our knowledge, we are the first group to take on this systematic search through the genome in live cells. We will use the most potent RNAi reagent for this study, which is usually out of reach for academic labs because of the enormous cost and the ever-changing annotation of the human genome. But being part of the large EU project MitoCheck allowed us to work with one of the leading suppliers of siRNAs, Ambion Europe, Ltd., to produce a genome-wide library for this project,” says Dr. Jan Ellenberg, EMBL Group Leader and co-initiator of the MitoCheck project.


Undertaking such a large project required tens of thousands of siRNA molecules, as two to three molecules are targeted specifically against each human gene. EMBL chose Ambion as a supplier of the siRNA library because its library could be tailored to the most up-to-date list of human target genes – a list provided by the Wellcome Trust Sanger Institute, the MitoCheck bioinformatics partner. Also, Ambion’s siRNA libraries utilize a siRNA design algorithm developed by Cenix BioScience GmbH (an EMBL spin-off company), leading to high efficacy of the siRNAs.

“We are happy to work with Ambion and Cenix BioScience on this ambitious project. This represents the first use of a genome-wide library of chemically synthesized siRNAs in academic research and these partners have provided us with the tools to carry out this search,” says Ellenberg. “Thousands of genes have been tested in the initial phase of the project and the results are very promising.”

The systematic search and analysis of the screen is set to be completed by the end of 2005.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
