Waste removal in worms reveals new mechanism to regulate calcium signaling
Date:1/4/2013

Calcium is so much more than the mineral that makes our bones and teeth strong: It is a ubiquitous signaling molecule that provides crucial information inside of and between cells. Calcium is used to help our hearts beat regularly, our guts to function appropriately and even for fertilization to occur. It is also needed to help muscles and blood vessels contract, to secrete hormones and enzymes and to send messages throughout the nervous system.

In a study published in Current Biology, scientists from the University of Rochester Medical Center, Marquette University and Oberlin College discovered a new way in which calcium signaling may be controlled. Study authors say their findings define a mechanism for regulating calcium signaling that has never been recognized before and should be of great help to the thousands of scientists who study the extremely important role of calcium signaling in health and disease.

"It is hard to find a biological process that is not influenced by calcium signaling," said Keith Nehrke, Ph.D., study author and associate professor of Nephrology and Pharmacology & Physiology at the Medical Center. "In many cases, calcium signaling is absolutely central. The rise and fall of calcium is the molecular clock that times the execution of important processes like the regular and coordinated beating of our hearts."

Nehrke, along with lead study authors Allison L. Abbott, Ph.D., and Benedict J. Kemp, Ph.D., of Marquette University, made the finding while studying an unglamorous, yet scientifically ideal subject matter worm poop.

Worms produce their own body weight in embryos every day, which requires immense caloric intake. However, as in all other animals, food is transformed into waste, which must be expelled from the body. As a result of their rapid nutrient intake, worms defecate a lot and fast every 50 seconds. The fidelity of this biological rhythm is critical for good health and relies on
