Argonne researchers uncover structure of new protein implicated in diabetes

Scientists at Argonne National Laboratory, in collaboration with researchers from the Sanford-Burnham Medical Research Institute, recently determined and analyzed the three-dimensional structure of a protein found in the nuclei of liver and pancreatic cells. The protein, called hepatocyte nuclear factor 4α (HNF-4α), plays a critical role by binding to specific DNA sequences and regulating the production of a number of key proteins for normal cellular processes. Some of its mutations have been linked to maturity-onset diabetes, kidney failure and metabolic syndrome.

Argonne marks 70th anniversary of first man-made nuclear chain reaction

Seventy years ago today on Dec. 2, 1942, World War II was raging overseas, and Enrico Fermi and 48 other scientists gathered in a squash court beneath the football stadium at the University of Chicago. They were about to witness the first self-sustaining nuclear chain reaction—soon to be a revolutionary new source of energy.
