Selenium: A vital toxin for humans

A rare trace element from the bedrock turned out to be a prerequisite for human life. Since the discovery of selenium 200 years ago, researchers have tried to understand more.

Collaborations

We have many collaborators around the globe and we believe that good academic collaborations are key facilitators for scientific progress. Here is a list of some of our more active collaborations, with links to the collaborator websites for more information.

At ̽ѡ

Within our Department, we are collaborating with the groups of Rikard Holmdahl and Roman Zubarev in projects where we are studying redox control of inflammation and the redox biology of cancer, for which we also received funding from the Knut and Alice Wallenberg Foundation (for more information, click and ).

With Rolf Kiessling and Stina Wickström we are studying the redox biology of antitumoral immunity, with a special focus on how to strengthen the resistance of T and NK cells towards high levels of exogenous oxidative stress.

Elsewhere in Sweden

Together with in Gothenburg we are studying the redox biology of cancer, with an aim of developing more efficient therapeutic protocols.

International Collaborators

A long-standing collaborator of ours is Edward “Ed" Schmidt, who is an outstanding expert in genetic mouse models and with whom we have had and continue to have many joint projects. Ed has a  and, similarly to us, a second , which he runs together with Peter Nagy. We are also collaborating with , an expert in hydrogen sulfide and protein persulfidation.

We have close collaborations on trace element research and glutathione peroxidases with in Jena, Germany, with several joint publications and ongoing collaborative projects.

Another close collaboration is with at NCATS, NIH, with whom we are discovering and characterizing novel inhibitors of selenoproteins, with possible applications for cancer treatment. Drs. Hall and Arnér are also jointly supervising PhD students in the KI-NIH joint PhD program (more information and here), from where graduated in June 2023 (her Ph.D. dissertation is available ) and into which was admitted in the fall of 2023.

Important redox systems of neglected tropical disease vectors characterised

Researchers from the Division of Biochemistry, in collaboration with scientists from University of L'Aquila in Italy, Rush University and University of California San Francisco in the US, have now for the first time characterized the crystal structure and activity of the B. malayi and O. volvulus antioxidant systems, thereby paving the way for the development of more efficient targeted redox-based therapies.

Gold-based cancer therapy could face competition from other substances

The gold complex auranofin has traditionally been used for treating rheumatism but is also being evaluated as a treatment for certain forms of cancer. Researchers at ̽ѡ in Sweden now show that other molecules that inhibit the same biological system have a more specific effect than auranofin and therefore may have greater potential as cancer therapies.
