This Table describes the significant comparison that differentiated among pathology groups (Normal, Benign, Glioblastoma, Medulloblastoma, Metastasis: Lung and Breast) for each validated microRNA. Comparisons are reported together with the corresponding fold changes and p-Values with the exception of those comparison in which the entire group had RT-PCR Ct value close or equal to 40 (not expressed).
