ABSTRACT
Objective To explore the expression of miRLet-7 family members in breast cancer and its correlation with overall survivals (OS), and to find more effective molecular targets for breast cancer prevention and treatment.Methods Kaplan-Meier (KM) plotter online database was used to analyze the correlation among the expression of Let-7 family members (Let-7a, 7b, 7c, 7d, 7e, 7f, 7g, 7i, miR-98, miR-202) correlated with overall survival (OS) and the prognosis and clinical pathological parameters of breast cancer patients, and Hazard ratio (HR), 95%confidence interval (CI), and P value were determined.ResultsThe study showed that the high expression level of Let-7a, Let-7b, Let-7c, Let-7e, Let-7f, Let-7g, miR-98 and the low expression level of miR-202 was associated with better OS for breast cancer patients (P<0.05).We further assessed the prognostic value of Let-7 in different subtypes and clinical stage.The expression of Let-7a, Let-7b, Let-7f, Let-7g, miR-98, miR-202 was related to clinical stage (P<0.05).Let-7a, Let-7b, Let-7c, Let-7e, Let-7f, Let-7g, miR-98 and miR-202 was related to lymph node status (P<0.05).In triple-negative breast cancers (TNBC), with breast cancer subtype, the expression of Let-7b, Let-7c, Let-7g and miR-202 was significantly correlated to overall survival (P<0.05).Conclusion The Let-7 is significantly correlated with OS in breast cancer patients.The results suggested that members of the Let-7 have different values in predicting the prognosis of breast cancer.Among them, Let-7b, Let-7g and miR-202 are closely related with clinical stage and TNBC, and might promote development of Let-7 as targeted inhibitors for the treatment of breast cancer.
