| Osteosarcoma (OS) is the most common primary bone malignancy in children and adolescents which has the
survival rate of 20% in its advanced stages. Osteosarcomas are mostly resistance to our common treatments. DNA
damage response (DDR) is a specialized multistep process containing abundant proteins which are necessary for
the survival of any cell and organism. DDR machinery detects a diversity of DNA lesions and inhibits the cell
cycle progression if these lesions are not repairable. DDR is involved in aging, age-related diseases, and cancer. In
recent years, DDR inhibitors have gained the attention of researches due to their potentials in offering novel
therapeutic targets and improving the response of many cancers to either chemo- or radio-therapy. In this regard,
we tried to gather a great body of evidence about the role of DDR ingredients in osteosarcoma’s initiation/
progression, prognosis, and treatment. |
