Abstract

The present study aimed to investigate the expression and significance of microRNA‑31 (miR‑31) in children with acute B‑lymphoblastic leukemia (B‑ALL). Bone marrow specimens and peripheral blood were collected from children with B‑ALL (n=38) and healthy controls (n=18). Total RNA was extracted and the expression levels of miR‑31 were measured using quantitative PCR. In addition, a receiver operating characteristic curve was generated, and the area under the curve (AUC) was calculated to evaluate the diagnostic value of miR‑31 for the development of B‑ALL. miR‑31 expression was significantly lower in the B‑ALL group compared with in the control group (P<0.05). Additionally, the expression levels of miR‑31 in the B‑ALL group before treatment were markedly lower than in the B‑ALL group after treatment, and miR‑31 expression was significantly lower after 30 days of treatment compared with after 12 weeks of treatment. Furthermore, miR‑31 expression in the group of children ≥10 years of age was higher than that in the group of children <10 years of age. Furthermore, the expression levels of miR‑31 were higher in the low‑risk group compared with in the medium‑ and high‑risk groups (P<0.05). When the cutoff value was set at 1.8, the AUC of miR‑31 for B‑ALL diagnosis was 0.915 (95% CI, 0.828‑1.000; P<0.0001), with a sensitivity and specificity of 80.8 and 100%, respectively. In conclusion, miR‑31 may exert an anticancer role in B‑ALL in children and may be a potential marker to assist in diagnosis and prognostic prediction.
