The same types of signals stimulate migration of ovarian cancer cells, which follow specific signals to move from the female genital tract towards the peritoneum and stroma, where they form metastases. These findings were presented today (May 13th) by Denise Montell, Professor of Biological Chemistry at the Johns Hopkins University School of Medicine in Baltimore (Maryland), at the Workshop on Cell Migration: From Molecules to Organisms and Diseases promoted by the European School of Molecular Medicine (SEMM) and the University of Milan, in collaboration with IFOM – The FIRC Institute for Molecular Oncology of the Italian Foundation for Cancer Research, and IEO – European Institute of Oncology. Venue of the Workshop is the IFOM-IEO Campus (via Adamello, 16, Milan) that was recently opened and represents the biggest area dedicated to the oncological research in Europe.
Epithelial ovarian cancer (EOC) develops in the ovary, especially in the cells that cover the outer surface of this organ. As it scores 190,000 new cases each year worldwide (61,000 in Europe), it has fuelled intensive investigations all over the world. Denise Montell and her group have been studying cell migration for years, in the attempt to elucidate the key elements that govern their movement. To this purpose the scientists have set up a system called “border cells model”, employing fruit fly (Drosophila melanogaster) cells, which has led to the identification of specific regulatory signals that cells respond to. “Epithelial cells migrate in a way that is reminiscent of the migratory behavior of cancer cells - explains the scientists – and this moving is highly coordinated as it responds to extracellular signals present in the surrounding microenvironment. Using our experimental model we were able to identify three kinds of signals.”
“Basic science results such as Montell’s have great value – points out Marina Mione, head of the IFOM program Genetic control of cell migration in zebrafish, and member of the Workshop’s Scientific Committee – as they pave the way for future clinical application. Devising new therapeutic approaches implies previous acquisition of solid scientific baseline information. Moving from observations acquired in physiological conditions Montell opens a number of new avenues that will promote our understanding of pathological conditions”.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
