Their findings, which appear in the current issue of the journal Cancer Cell along with an independent commentary on the discovery, end a major controversy in the field of cancer research as to whether aneuploidy is a cause or a consequence of cancer.
Virtually all human cancers have an abnormal number of chromosomes. Therefore, it has been long suspected that gene mutations which promote erroneous chromosome separation during cell division are to blame for tumor development. However, because of experimental limitations this was difficult to prove.
“By using a combination of new and established mouse models for human cancer, we were able to prove that aneuploidy causes cancer and elucidate the mechanism by which it does so,” explains Jan van Deursen, Ph.D., Mayo Clinic cancer biologist and senior author.
Significance of the Research
These findings explain how chromosomal errors can cause cancer. They prove the role of aneuploidy in the elimination of genes that suppress tumor formation.
“Now that we understand the mechanism by which aneuploidy causes cancer, it will be easier for other researchers to build on this knowledge — and target new drugs accordingly,” says Dr. van Deursen.
Researchers included Darren Baker; Fang Jin, M.D.; and Karthik Jeganathan, all of Mayo Clinic. The research was supported by the National Institutes of Health.About Mayo Clinic

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...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

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...
