Breakthrough in plant medicine production

25.06.2008
A research team of scientists from Wageningen University and Research Centre in the Netherlands has succeeded in further unravelling and manipulating the glycosylation of proteins in plants.

This is the result of the research soon to be published in the renowned scientific magazine The Plant Cell. The scientists expect that this knowledge will allow plants to be applied more often in the production of therapeutic proteins, an important type of medicine.

The discovery fits in with technology developed by the Wageningen UR research institute Plant Research International for the production of biopharmaceuticals in plants.

Proteins in plants, animals and people are equipped with various sugar chains in a process known as glycosylation. The sugar chains are of significance to the functioning of many proteins. Moreover, their identity and uniformity is crucial to the quality of therapeutic proteins.

The glycosylation of proteins in plants, people and animals basically consists of three stages. Initially sugar chains are constructed, which then attach to the protein in specific locations. Finally, the sugar chains are further modified as specific sugars are attached to the chain.

“We are the first institute in the world to identify a gene in plants that is involved in the construction of these sugar chains, the first stage in glycosylation,” says scientist Maurice Henquet. “It seems that the chains become increasingly uniform as the expression of this gene is reduced.” One type of chain, a relatively simple one, is mainly developed. The sugar chains which are attached to the proteins are therefore a better starting point for making adjustments that are designed to optimise the biological function as medicine.

“From now on we will be able to improve the manipulation of glycosylation,” Henquet continues. “And plants will become even more suitable for medicine production.”

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
