How a cellular mechanism can be used for other purposes
An international team of researchers led by the Universities of Bonn and Ulm has investigated how a cell’s own "protein shredder" can be specifically programmed to fight cancer. The researchers were able to demonstrate the degradation of proteins that are overly active in breast cancer, for ...
New group of proteins prevent dangerous clumps associated with neurodegenerative diseases
Researchers at the University of Tokyo have discovered a new group of proteins, remarkable for their unusual shape and abilities to protect against protein clumps associated with neurodegenerative diseases in lab experiments. The Hero proteins are heat resistant and are widespread in animals from ...
First comprehensive map of the proteome of the model plant Arabidopsis thaliana
Plants are essential for life on earth. They provide food for essentially all organisms, oxygen for breathing, and they regulate the climate of the planet. Proteins play a key role in controlling all aspects of life including plants. Under the leadership of the Technical University of Munich ...
Proteins can be controlled with light of different wavelengths. Even several at once, thanks to a new tool. Light-sensitive proteins, also known as optogenetic tools, can be switched on and off by light pulses, thus triggering specific cellular processes. A research team at Ruhr-Universität ...
Sustainable light sources
In the FET Open project ENABLED, TU Graz protein-designer Gustav Oberdorfer is working together with researchers from Spain and Italy on environmentally friendly and inexpensive light-emitting diodes. The basis for this vision is being laid at the Institute of Biochemistry at Graz University of ...
Power generation from ambient humidity using protein nanowires
Scientists at the University of Massachusetts Amherst have developed a device that uses a natural protein to create electricity from moisture in the air, a new technology they say could have significant implications for the future of renewable energy, climate change and in the future of ...
Sticky proteins from sea mussels
If the heart muscle is damaged, repairing the constantly active organ is a challenge. Empa researchers are developing a novel tissue adhesive inspired by nature, which is able to repair lesions in muscle tissue. They have taken advantage of the incredible ability of marine mussels to adhere to ...
Scientists decipher the activation chain of protein degradation
Proteins are molecular work horses in the cell that perform specific tasks, but it is essential that the timing of protein activities is exquisitely controlled. When proteins have fulfilled their tasks, degradation of these proteins will end processes that are unneeded or detrimental. To control ...
Ice can tear apart cells in cryo-storage: Polymers can save the day
Cell therapies hold great promise for revolutionizing the treatment of cancers and autoimmune diseases. But this multibillion-dollar industry requires long-term storage of cells at super-cold cryogenic conditions, while ensuring they'll continue to function upon thawing. However, these cold ...
Proteins can be responsible for the fact that the active ingredients of drugs are simply released from the target cells. You can watch them do this now. Certain medications, such as those used to treat cancer, lose their effect because proteins in the membrane of the target cell simply expel them ...
