A study using Drosophila flies reveals new regulatory mechanisms of cell migration

21.03.2014

The study by Sofia J. Araújo sheds light on the fields of development, wound healing, angiogenesis, and tumour invasion, processes in which cell migration is crucial.

A study by Sofia J. Araújo, a Ramón y Cajal researcher with the Morphogenesis in Drosophila lab at the Institute for Research in Biomedicine (IRB), elucidates the genetic regulation of cell migration.

Published today in the scientific journal Plos One, the research is part of the thesis work performed by Elisenda Butí, first author of the article.

Cell migration is highly coordinated and occurs in processes such as embryonic development, wound healing, the formation of new blood vessels, and tumour cell invasion. For the successful control of cell movement, this process has to be determined and maintained with great precision.

In this study, the scientists used tracheal cells of the fruit fly Drosophila melanogaster to unravel the signalling mechanism involved in the regulation of cell movements.

The research describes a new molecular component that controls the expression of a molecule named Fibroblast Growth Factor (FGF) in Drosophila embryos. The importance of FGF in cell migration was already known but little information was available on its genetic regulation.

In the study, Araújo and her team have discovered that a protein called Hedgehog, known to be involved in morphogenesis, regulates FGF expression.

“This is the first time that a direct connection has been demonstrated between the Hedgehog pathway and an increase in FGF during cell migration,” says Araújo.

The results are really interesting for biomedicine,” explains the researcher, “as the Hedgehog pathway is overexpressed in some of the most invasive tumours, such as the most common kind of skin cancer.”

The team explains that this is a step forward for research into cell migration mechanisms and that future applications will emerge as further investigation and studies are conducted.

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...

Im Focus: Designing Architecture with Solar Building Envelopes

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...
