A new European research network MICROENVIMET: understanding and fighting metastasis by modulating the tumour microenvironment

09.07.2008
The aggressive character of a tumour is related to the capacity of the cancer cells to form metastases from a primary tumour. Metastasis is the most serious challenge for cancer treatment.

The tumour cells can disseminate into the organism by using the blood or lymphatic stream. Recent data suggest that the site of implantation of secondary foci or metastases is preset by the elaboration of an appropriate microenvironment.

These novel information led to the emerging concept of “premetastatic niche”. In addition, cancer cells must acquire new properties ensuring their mobility and the invasion of various tissues. Cancer stem cells are thought to constitute the proliferative potential of the tumoral mass and could represent the source of cells metastasizing.

The tumour cell-centrered view of the metastatic process is now revisited taking into account the important contribution of the tumor microenvironment consisting of both cellular and non cellular components, in primary tumors as well as in secondary foci.

A new European network, entitled MICROENVIMET, developed within the 7th EU framework is coordinated by Professor Agnès NOEL (Laboratory of Tumour and the Development Biology, GIGA-Cancer research center of the University of Liege, Belgium). This European scientific network entitled “Microenvimet: Understanding and fighting metastasis by modulating the tumour microenvironment through interference with the protease network” (http://www.microenvimet.eu) gathers 8 international partners. It is funded to the amount of 2.999.689 euro for 4 years by the European commission.

The purpose of the project “microenvimet” is to elucidate and understand the early mechanisms of the metastatic dissemination by studying the contribution of tumour microenvironment during various stages of epithelial cancer evolution: the primary tumour growth, the premetastatic phase preceding the dissemination of the cancer cells and the metastatic phase during which the secondary foci develop. It aims at identifying molecular targets contributing to early steps of the tumour progression. The project is focused on the mechanisms underlying the elaboration of a favorable «soil » for the establishment of metastases (“premetastatic niche”).

Its original approach consists in modifying the tumoral microenvironment, interfering with proteases which constitute important regulators of the interactions which are established between tumoral cells and their cellular and molecular microenvironment. This project is based on the exploitation of innovating technological platforms: genomic platform for the analysis of the RNA messengers and the recently identified microRNA, phage library for the development of blocking antibodies against the identified targets, platform of computer-assisted image analysis and transgenesis platform.

Im Focus: Making Waves

Computer scientists use wave packet theory to develop realistic, detailed water wave simulations in real time. Their results will be presented at this year’s SIGGRAPH conference.

Think about the last time you were at a lake, river, or the ocean. Remember the ripples of the water, the waves crashing against the rocks, the wake following...

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...
