ObjectiveTo summarize the research progress of microRNA-200 (miR-200) family in triple-negative breast cancer (TNBC).MethodsRelevant literatures at home and abroad were systematically retrieved and read to review the research progress of miR-200 family in TNBC in recent years.ResultsThe miR-200 family played an important role in the proliferation, invasion, and metastasis of TNBC, as well as the resistance to treatment. It could also be used as potential therapeutic targets and biological predictors. Different miR-200 family members and differential expression mediated various targeting effects, which may be related to differences in signaling pathways and cellular environment.ConclusionsmiR-200 family plays a key regulatory role in the occurrence and development of TNBC, and it is expected to provide new ideas for the treatment and prognosis evaluation of TNBC. However, its mechanism of action still needs further study.
