MicroRNA expression in relation with clinical evolution of osteosarcoma

Osteosarcoma is the most common malignant bone tumor. Early diagnosis remains a major challenge, mainly because of the lack of specific biomarkers. We performed miRNAs expression analysis through qPCR in affected and paired healthy bone derived from osteosarcoma patients. Hierarchical clustering using the top ten miRNAs with differential expression showed two main clusters. One integrated by patients with the presence of metastasis or relapse...
