Plasma profiling of miRNAs in human specimens from osteosarcoma patients.. Homo sapiens

Osteosarcoma (OS) is the primary bone tumor in children and young adults. Currently, there are no reliable, non-invasive biological markers to detect the presence or progression of disease, assess therapy response, or provide upfront prognostic insights. Using a qPCR-based platform that analyzes more than 750 miRNAs, we analyzed control and diseased-associated plasma from human cases of OS to identify a profile of differentially expressed miRNAs. Overall design: Comprehensive miRNA expression profiling was completed using the Exiqon miRNome platform (human panels I+II, V3) on 20 disease samples (10 localized, 10 metastatic) and 15 healthy controls.
