In this study we suggested a possible role of prion proteins genes in osteosarcoma. Therefore, the inhibition of prion proteins expression must be tested because it could represent a new approach to the molecular treatment of osteosarcoma. Although osteosarcoma is the most common bone malignancy, the molecular and cellular mechanisms influencing its pathogenesis have remained elusive. Prion proteins (PRNP and PRND), known mostly for its involvement in neurodegenerative spongiform encephalopathies, have been recently demonstrated to be involved in resistance to apoptosis, tumorigenesis, proliferation and metastasis.Summary Statement
