Walter and Eliza Hall Institute scientists have made a significant advance in understanding how potassium channels, which permit the flow of electric currents central to many of the body's biological processes, control the flow of these currents.

Two new studies by researchers at the University of Washington further our understanding of the molecular steps in the PLC cascade, a G protein-coupled receptor signaling mechanism that underlies a wide variety of cellular processes, including egg fertilization, hormone secretion, and the regulation of certain potassium channels.

A new study involving the University of Iowa, Mayo Clinic and two other institutions provides insight on weight control, suggesting that a ATP-sensitive potassium channel critical to survival and stress adaptation can contribute to fat deposition and obesity.
