Saliva test for microRNA could detect oral cancer

Source: www.medpagetoday.com Author: Chris Emery, Contributing Writer, MedPage Today Researchers say they have identified dozens of microRNAs in saliva, raising hopes that saliva tests could assist in early detection of oral cancers. Analyzing patient saliva with a polymerase chain reaction (PCR) technique, the researchers identified about 50 microRNAs — molecules that halt mRNA translation and/or lead to mRNA [...]
