SRP172569 PRJNA508535 GSE123376 Differential expression of exosomal miRNAs between medulloblastoma patients and healthy controls We characterized circulating exosomal miRNA profiles by miRNA-seq to identify those differentially expressed in children with MB relative to heathy controls Overall design: Plasma samples from 4 medulloblastoma patients and 4 healthy controls were enrolled in the experiment. Exosomes were extracted, total RNA were isolated from the identified exosomes.miRNA profilings were performed. GSE123376 pubmed 32483145
