Optogenetic tool enables targeted and reversible gene expression control in plants in the presence of ambient light
A research team of biologists within the CEPLAS Cluster of Excellence at Heinrich Heine University Düsseldorf (HHU) has succeeded, together with colleagues from the University of Freiburg, to develop an optogenetic tool for use in plant research. The tool can be used to control plant processes ...
By coupling a bacterial injection system with a light-controlled molecular switch, scientists are able to inject proteins into eukaryontic cells
When bacteria such as Salmonella or Yersinia cause fever, diarrhoea or abdominal pain, tiny "injection needles" are at work: their type 3 secretion system, or T3SS for short, shoots bacterial virulence proteins directly into the eukaryotic host cells. Researchers have thought of using bacterial ...
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 ...
While searching for biological markers for suicide risk, a Viennese research team has gained new insights into the relationship between environmental factors and genetics. Traumatic childhood experiences play an essential role and leave traces in the brain. To a large extent, suicide is a taboo ...
Major population study investigates the interplay between genetics, educational attainment and cardiovascular disease
A German and British research team lead by the Technical University of Munich (TUM) has examined the interplay between genetics, cardiovascular disease and educational attainment in a major population study. Genetic variants which had been linked to educational attainment in other studies were ...
Molecular similarities in mice and humans exposed to trauma
Post-traumatic stress disorder (PTSD) is a mental illness that can develop after experiencing a traumatic event. Greater awareness of PTSD emerged when large numbers of soldiers returning from the Iraq war reported symptoms. Other traumatic events such as experiencing childhood or sexual abuse, a ...
Researchers regulate the activity of RNA molecules
Messenger RNA molecules contain genetic information and thus control the synthesis of proteins in living cells. Biochemists at the University of Bayreuth and the University of Bonn have now discovered a way to regulate this process which is central to gene expression: Certain actinobacteria ...
So far, development has been mainly based on a trial-and-error approach. But a novel method might help save a lot of time. A new strategy for designing light-sensitive proteins has been developed by researchers at Ruhr-Universität Bochum (RUB). Such proteins, also known as optogenetic tools, can ...
Engineers have mimicked the human brain with an electronic chip that uses light to create and modify memories
Researchers from RMIT University drew inspiration from an emerging tool in biotechnology - optogenetics - to develop a device that replicates the way the brain stores and loses information. Optogenetics allows scientists to delve into the body's electrical system with incredible precision, using ...
The University Hospital Bonn plans to have a stronger focus on pharmacogenetics – thus emphasising the influence of genetic characteristics on the effect of medications. This idea embodies the approach for personalised medicine. To integrate extensive pharmacogenetic analysis into the clinical ...
