Epigenetic changes in osteosarcoma

Abstract

Osteosarcoma is one of the most prevalent primary bone tumors. The pathogenesis and molecular development of this tumor remains elusive. The prognosis is unfavorable due to lack of effective treatment methods. Recent advances in the epigenetics have brought a profound impact on the understanding of molecular mechanisms that lead to osteosarcoma. In this review, we summarized the current literature on epigenetic changes that are thought to contribute to the carcinogenesis of osteosarcoma, and discussed the potential diagnostic and therapeutic applications as well as future areas of research.
