Figure 1. Identification of miRNAs differentially expressed in osteosarcoma. (A) Expression of miRNAs in osteosarcoma tissues and adjacent normal tissues detected using real time PCR. ** P< 0.05 vs. adjacent tissues group. (B) Relationship between miR-506-3p and survival in osteosarcoma patients. (C) Expression of miR-506-3p in hFOB 1.19, HOS, U2OS, and MG63 cells detected using real time PCR. ** P< 0.05 vs. hFOB 1.19 cells
