As an important member of tyrosine kinase family, c-kit receptor causes specific expression of certain genes, regulates cell differentiation and proliferation, resists cell apoptosis, and plays a key role in tumor occurrence, development, migration and recurrence through activating the downstream signaling molecules following interaction with stem cell factor (SCF). The abnormality of SCF/c-kit signaling pathway is closely related to some certain tumors. The discovery of c-kit receptor-targeted drugs has promoted clinical-related cancer's diagnosis and treatment. In this paper, we review recent research progress on c-kit receptor-mediated signal transduction and its potential therapeutic application as a target in tumor-related diseases.
Keywords: c-kit receptor; signal transduction; targeted therapy; tumor.
