Recent studies have shown that miRNA-506 plays an important role in tumorigen- esis and progression of many types of tumors. In vitro and in vivo experiments revealed that miRNA-506 suppresses progression of sev- eral tumors and promotes response of tumor cells to chemotherapy. However, miRNA- 506 plays different roles in different tumors. This review summarizes the functions and mechanisms of miRNA-506 in different tumors to identify a new target for the targeted ther- apy of certain tumors. Keywords: microRNA-506, tumor, tumor suppressor, targeted therapy 微小RNA(microRNAs)是一类短链、非编码RNA miR-510、miR-513和miR-514)的一员,与晚期卵巢 [4-5] 分子
