Latest Potassium channel Stories
BK channels (large-conductance, Ca2+-dependent K+ channels) are essential for the regulation of important biological processes such as smooth muscle tone and neuronal excitability.
The human genome encodes 243 voltage-gated ion channels.
Using a unique and relatively simple cell-based fluorescent assay they developed, scientists have identified a means by which fluoxetine, the active ingredient in Prozac, suppresses the activity of the TREK1 potassium channel.
Australian researchers have come one step closer to understanding how the rhythm of the heartbeat is controlled and why many common drugs, including some antibiotics, antihistamines and anti-psychotics, can cause a potentially fatal abnormal heart rhythm.
Scientists in the Hotchkiss Brain Institute at the Faculty of Medicine, University of Calgary, have discovered a new mechanism that nerve cells (neurons) use to fine-tune their electrical output.
Scientists are closer to solving one of the many mysteries of multiple sclerosis and other demyelinating diseases, thanks to a recent study conducted at the Salk Institute for Biological Studies.
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.
