Scott Valastyan, lead author on the study, describes it as presenting "detailed mechanistic insight regarding the process of tumor metastasis, and identifies several key regulators of this process that might prove to be interesting diagnostic and/or therapeutic targets in breast cancer."
Dr. Weinberg's group previously showed that the human microRNA, miR-31, suppresses breast cancer metastasis and that its expression is associated with patient outcome. miR-31 regulates the expression of almost 200 genes. However, in this new paper, the authors identify that re-introduction of three miR-31 targets is sufficient to completely reverse miR-31's influence on metastasis.
The researchers characterized both the individual and overlapping contributions that each of these three miR-31 effectors makes to the metastatic process. While three distinct steps are affected by this cohort of miR-31 targets (namely local invasion, early post-intravasation events and metastatic colonization), of particular interest was the finding that two of the three effectors regulate metastatic colonization – the final and rate-limiting step of metastasis.
Scott Valastyan emphasizes that "Our finding that miR-31, integrin-alpha5, and radixin affect the process of metastatic colonization may be of particular interest in light of the fact that colonization efficiency is strongly associated with patient survival outcome in many human tumor types – including breast cancer".

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
