Abstract

MicroRNAs (miRs) are small non‑coding RNAs that play important roles in cell differentiation and survival. Abnormal expression of miRs has been demonstrated in numerous types of cancer, including acute myeloid leukaemia (AML). The aim of the present study was to evaluate miR‑181 expression at diagnosis and following the completion of chemotherapy in AML patients, with regard to clinical response and outcome, particularly in patients treated with azacitidine. miR‑181 expression was analysed using reverse transcription‑quantitative polymerase chain reaction in 95 bone marrow specimens from newly diagnosed AML patients and in 20 healthy subjects for comparison. The results revealed upregulated miR‑181 expression in the total cohort of AML patients, which was correlated with longer survival. However, in a subset of older AML patients treated with azacitidine, low miR‑181 expression at diagnosis was a predictor for complete remission and prolonged survival. The findings indicated that miR‑181 has an important role in AML and determines response to azacitidine treatment in older AML patients.
