    Death Signal for Brain Tumor Cells

    A protein which acts as a danger signal in the body causes an unknown form of cell death in malignant brain tumors. This process is characterized by the formation of giant mitochondria in the dying cells. This has been discovered by scientists of the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) and the Institute of Pathology of Heidelberg University. Healthy brain cells, by contrast, are resistant to this form of cell…

    EMBL scientists identify proteins that ensure iron balance

    Most organisms need iron to survive, but too much iron is toxic, and can cause fatal organ failure. The same is true inside cells, where iron balance must also be maintained. In a study published today in Cell Metabolism, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have discovered that a group of proteins named IRPs ensure that this iron balance is kept and as such are essential for cell survival. More…

  • Article - 15/07/2010 The photo shows computer models of two structurally different classes of transmembrane proteins: α-helical and β-barred-shaped ones.

    A special focus on intercellular mediators

    Transmembrane proteins constitute around one third of all cellular proteins. Around half of all drugs that are currently on the market target the function of a specific class of transmembrane proteins, i.e. the G-protein coupled receptors. However, little is yet known about how transmembrane proteins are integrated into the membranes and how they are folded. Dr. Jörg H. Kleinschmidt hopes to shed light into the mechanisms of membrane protein…

    Membrane proteins

    Around thirty per cent of all cellular proteins are located in or on a biological membrane. Numerous diseases are associated with defects in these proteins. It is estimated that around 50 per cent of all drugs developed by the pharmaceutical industry in the future will target the different membranes of cells. However it is quite difficult to biochemically investigate biological membranes. These are the many reasons why many research groups and…

  • Press release - 10/07/2010 The mitochondrial complex I is a huge complex consisting of 40 proteins located in the inner membrane of the cellular powerhouses.

    Nanomachines in the powerhouses of the cell

    Scientists from the University of Freiburg and the University of Frankfurt have elucidated the architecture of the biggest protein complex of the cellular respiratory chain. They discovered in this molecular complex a previously unknown energy conversion mechanism, which is essential for the cell to be able to utilise the energy contained in food.

  • Article - 10/07/2010 The schematic shows the two mitochondrial membranes and the protein import and sorting machinery in and around them.

    Membrane proteins and the import business of mitochondria

    The powerhouses of cells are surprisingly dependent on external help. More than ninety per cent of all proteins required by the mitochondria are produced outside the outer mitochondrial membrane. How are these proteins transported across the membrane and how do they find their way into the mitochondria? A group of researchers led by Prof. Dr. Chris Meisinger at the University of Freiburg has been investigating the role of large protein complexes…

  • Article - 05/11/2009 The photo shows three transparent worms against a grey background; certain areas in the worms give off a neon green colour.

    Does stress increase the lifespan of worms?

    It is known that vital oxygen can also turn into so-called free radicals in the body, thus damaging important molecules. Some scientists believe that the accumulation of such damage causes organisms to age. Dr. Ekkehard Schulze and his team at the University of Freiburg are investigating a previously unknown signalling network that reacts to oxidative stress in the cells of the threadworm Caenorhabditis elegans. The worm serves as a model for…

    On the track of fascinating diatoms

    Diatoms make a considerable contribution to the production of oxygen and biomass in the worlds oceans and aquatic ecosystems. However up until now little is known about the molecular biology and chemistry of these eukaryotic algae. Prof. Peter Kroth and his team at the University of Constance are hoping to shed more light on these algae. The team has recently been involved in the deciphering of the Phaeodactylum tricornutum genome research that…

    A kiss of death for cells

    Prof. Dr. Peter Krammer of the German Cancer Research Centre has considerably contributed to clarifying the apoptotic signalling pathways in both normal and malignant cells. In addition he has developed new therapeutic strategies for the treatment of those diseases that are the result of defective apoptosis regulation.

  • Article - 13/05/2009 Inner and outer mitochondrial membrane: the ways in which precursor proteins that are destined for specific mitochondrial areas are very complex. The proteins Mia40 and Erv1 are located between the membranes and sort the intermembrane proteins.

    Mitochondria – making the impossible possible

    The transport of proteins across the two mitochondrial membranes is a very complex process. Huge molecular machines recognise the precursor proteins which are formed inside the cell and which are destined for the energy power stations of the cells. Some of these substances pass the outer and the inner membrane, some of them remain in the intermembrane area. How does the sorting of the molecules work? Five years ago, molecular biologist Dr.…

    Kay Diederichs – important insights in the fight against bacterial antibiotics resistance

    Bacteria will always find ways to defend themselves against substances such as antibiotics, thus inhibiting their effect. Many bacteria have pump systems that they use to actively remove antibiotic drugs from the cell. Prof. Kay Diederichs at the University of Constance is working on the elucidation of these mechanisms in order to produce useful information for the development of bacterial pump inhibitors.

    Skin might be able to close the translation gap

    Karin Scharffetter-Kochanek dermatologist and head of the Department of Dermatology and Allergology at the University Hospital of Ulm has spent a long time investigating skin ageing. Her specific focus on skin has not however restricted her understanding of ageing to barely deterministic or mechanistic details. Quite the opposite is true.
