Receptor tyrosine kinases in osteosarcoma and Ewing sarcoma / 国际肿瘤学杂志

ABSTRACT

Osteosarcoma and ewing sarcoma are the two most common types of primary malignant bone tumors. Receptor tyrosine kinases(RTKs),including varieties of cell growth factors and proto-oncogene pro-ducts,are the high-affinity cell surface receptors which play an important role in the normal physiological func-tion of cells. A large number of studies have demonstrated that the abnormal RTKs signaling pathways may pro-mote the tumorigenesis and development of osteosarcoma and ewing sarcoma by affecting tumor cell survival, proliferation,invasion and metastasis. Targeting treatment of RTKs is a promising therapeutic approach for osteosarcoma and ewing sarcoma.
