DNA replication is an extraordinarily complex multi-step process that makes copies of the body’s genetic blueprint. It is necessary for growth and essential to life. Now researchers at the California Institute of Technology (Caltech) and Vanderbilt University have found evidence that one of those steps may involve the telephone-like transmission of electrical signals regulated by a chemical “switch.”

Vanderbilt researchers have developed a new method to study cell signaling networks at single-cell resolution.

Vanderbilt investigators have developed a framework for studying cellular responses that could be used to identify the agents driving a range of biological processes in health and disease.

A Vanderbilt University-led research team has discovered a molecular “rheostat” in the brain’s appetite control center that may provide new insights into obesity, which is at epidemic levels in this country.

David Clapham, M.D., Ph.D., of Boston Children’s Hospital and Harvard Medical School, discusses his research on ion channels and cell signaling at his recent Flexner Discovery Lecture.
