中文摘要：

盘状结构域受体2（DDR2）是盘状结构域受体家族成员之一,是一种与肿瘤发展进程密切相关的受体酪氨酸激酶.研究表明DDR2在多数肿瘤细胞和组织中高表达,能够促进肿瘤的增殖、侵袭和转移,其高表达往往作为不良预后的标志.此外,DDR2点突变后能够增强肿瘤细胞对小分子酪氨酸激酶抑制剂达沙替尼的敏感性,提示DDR2可以作为一个新的药物作用靶点,值得进一步探究.

英文摘要：

Discoidin domain receptor 2 （DDR2）, a tyrosine kinase receptor belonging to DDRs family, is associated with progression of various cancers. Studies have indicated that DDR2 expression is upregulated in various cancer tissues, which could promote tumors proliferation, invasion, and metastases. Furthermore, patients with high DDR2 expression showed poor 5-year overall survival rate. In addition, DDR2 point mutation can enhance the sensitivity of tumor cells to small molecule tyrosine kinase inhibitor dasatinib, which suggests that DDR2 mutation may be a promising target for cancer therapy.
