Prostate cancer is the most common non-cutaneous cancer in American men. In May of 2012, the U.S. Preventive Task Force recommended that serum prostate specific antigen (PSA) screening no longer be recommended as standard clinical practice. A factor contributing to this recommendation is that many prostate cancers diagnosed via PSA-screening are indolent disease that will never progress. Current American Urologic Association recommendations stress informed decision making.

Saliva performs a number of extremely important biological functions that are instrumental in maintaining oral health. It has been estimated that more than 5 million people in the US suffers from salivary gland dysfunction. Secretion of saliva is driven by concerted activities of a number of ion channels and transporters. Although, it is believed that calcium is the primary intracellular factor that regulates fluid secretion, the molecular mechanism involved in the regulation of cytosolic calcium is not clearly understood.
