About us

Elias Arnér
Elias Arnér. Private picture

Elias Arnér, MD PhD, Prof./Head of Division

Elias was admitted as one of the initial ten students of the new MD PhD program at Karolinska Institutet in 1986. He completed his PhD in 1993 with studies on nucleotide metabolism, having Assoc. Prof. Staffan Eriksson as supervisor. In parallel with completing his medical studies Elias engaged in studies of mammalian thioredoxin reductase together with Prof. Arne Holmgren, which has since remained a significant research interest. During a post doc in 1998/1999 with Prof. August Böck in Munich, Germany, Elias studied the production of recombinant selenoproteins, which is another major field of research still conducted in the group. Elias returned to Karolinska Institutet in 1999 and in 2008 he succeeded Prof. Holmgren as head of the biochemistry division.

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 Karolinska Institutet

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 here and here).

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 Volkan Sayin and his group 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 laboratory in Montana and, similarly to us, a second laboratory in Budapest, which he runs together with Peter Nagy. We are also collaborating with Peter Nagy, an expert in hydrogen sulfide and protein persulfidation.

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

Another close collaboration is with Matthew Hall 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 here and here), from where Dorian Cheff graduated in June 2023 (her Ph.D. dissertation is available here) and into which Madeleine Barrett was admitted in the fall of 2023.

Together with Juan Sastre, Valencia, Spain, we are studying the in vivo roles of TRP14 (TXNDC17). Several other groups are also involved in those studies, and among them also Antonio Miranda Vizuete, Sevilla, Spain, who is a colleague and collaborator of ours that we have worked with for many years, and also now in different collaborative projects.

The group of Oliver Thorn-Seshold, Munich, Germany, is a fantastic group of talented chemical biologists that we are very happy to work with, which is a collaboration that also led to development and validation of RX1, which is a remarkably useful tool for assessment of TrxR1 activity in live cells.

Important redox systems of neglected tropical disease vectors characterised

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

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 Karolinska Institutet 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.
