Journal of Cellular and Molecular Medicine, Volume 27, Issue 11, Page 1592-1602, June 2023., 2023 Abstract Osteosarcoma is the most common primary bone cancer that affects adolescents with early metastatic potential and drastically reduces their long‐term survival rate if pulmonary metastases are detected at diagnosis. The natural naphthoquinol compound deoxyshikonin exhibits anticancer properties, so we hypothesized that it has an apoptotic effect
