Abstract

The present study aimed to elucidate the potential roles and regulatory mechanism of microRNA (miR)‑574‑3p in the development of chronic myeloid leukemia (CML). The expression of miR‑574‑3p in peripheral blood obtained from patients with CML was examined. Subsequently, miR‑574‑3p was overexpressed and suppressed in CML K562 cells to further investigate the effects of miR‑574‑3p on cell proliferation, and apoptosis. Furthermore, a luciferase reporter assay was performed to investigate whether interleukin‑6 (IL‑6) was a target of miR‑574‑3p. In addition, the regulatory association between miR‑574‑3p and the IL‑6/Janus kinase (JNK)/signal transducer and activator of transcription‑3 (STAT3) signaling pathway was explored. The expression of miR‑574‑3p in the peripheral blood obtained from patients with CML was significantly lower compared with that in healthy controls. Overexpression of miR‑574‑3p significantly inhibited the proliferation and induced the apoptosis of K562 cells, whereas suppression of miR‑574‑3p exhibited opposite effects. In addition, IL‑6 was identified to be a direct target of miR‑574‑3p. Overexpression of IL‑6 significantly promoted the proliferation and inhibited the apoptosis of K562 cells. Furthermore, overexpression of miR‑574‑3p inhibited the activation of the JAK/STAT3 signaling pathway, which was rescued by overexpression of IL‑6. The results of the current study indicate that miR‑574‑3p overexpression may serve an important role in inhibiting proliferation and inducing apoptosis of K562 cells via suppression of IL‑6/JAK/STAT3 signaling pathway activation. miR‑574‑3p may serve as a potential therapeutic target for CML.
