Scientists have a protein map of human saliva

U.S. scientists have a protein map (proteome) of human saliva proteins identified more than a thousand in the salivary gland secretions of people of different sex, age and race. The results can be used to develop a new, rapid and minimally invasive test for many dangerous diseases. The implementation of a large-scale research project required the participation of specialists from several research centers: the University of Rochester, The Scripps Research Institute and the University of South Carolina, University of California at San Francisco and the University of California in Los Angeles. The protein composition of human saliva was analyzed by mass spectrometry on samples from 23 healthy individuals from different ethnic groups. The results were compared with the data present on the proteins in the blood and tears. Identified at this time in the human salivary proteins, the markers of Alzheimer's disease, Parkinson's disease, Huntington's disease, colon cancer, pancreatic cancer and breast cancer and diabetes is. The researchers believe that their findings diagnosed significantly expand the list of diseases on the protein composition of saliva. The report on the study in the current issue of the Journal of Proteome Research published.
