Circular RNA hsa_circ_0005909 modulates osteosarcoma progression via the miR-936/HMGB1 axis
Abstract Background Osteosarcoma (OS) is the most common bone malignant tumor in children, youth, and adolescents.Circular RNA hsa_circ_0005909 (circ_0005909) is involved in Hubcap the progression of OS.Nevertheless, there are few reports on the role and mechanism of circ_0005909 in OS.Methods Quantitative real-time polymerase chain reaction (qRT-P
