Arne Holmgren (21 December 1940 — 6 January 2020[1]) was a Swedish biochemist known as a redox pioneer.
He received his Ph.D. in 1968 from the Karolinska Institute (KI) where he became associate professor in 1969,[2] and became a certified doctor in 1974.
He was appointed professor of medical protein chemistry and enzymology at KI in 1983, and in 1991 professor of biochemistry and director of the Department of Biochemistry at the Medical Nobel Institute, KI.
His investigations clarified basic sulphur and selenium-dependent redox mechanisms crucial for DNA synthesis, defence against oxidative stress and redox signalling in all living cells from bacteria to nerve cells.
His work remains of particular importance for cancer research and the treatment of infectious diseases and inflammation.
