OBJECTIVE: To detect the expression of RNA methyltransferase 14(METTL14) in bone marrow of patients with newly diagnosed acute myeloid leukemia (AML), and to investigate the clinical and prognostic significance of METTL14 expression in newly diagnosed AML.
METHODS: Bone marrow samples were collected from 100 patients with newly diagnosed AML as observation group and 60 patients with iron deficiency anemia AML as control group. And collected the clinical data of the AML patients. Real-time quantitative PCR (qRT-PCR) was used to detect the expression level of METTL14 in AML and IDA patients. The relationship between the expression level of METTL14 and clinicopathological features, prognosis was analyzed. Kaplan-Meier curves were used to analyze the effect of METTL14 on overall survival (OS) in AML patients. Cox risk regression model was used to analyze the prognostic factors affecting in patients with AML.
RESULTS: Compared with the control group, the expression of METTL14 was significantly increased in AML patients (P < 0.05). Compared with the METTL14 low-expression group, patients in the METTL14 high-expression group had advanced age, high bone marrow cell number, poor efficacyand poor prognosis(P < 0.05). The overall survival time of patients with the METTL14 high-expression group was significantly shorter than that of the low-expression group (P < 0.05). The high expression of METTL14 was an independent risk factor for poor prognosis in AML.
CONCLUSION: METTL14 is significantly overexpressed in AML patients, and its correlated with poor clinicopathological features and poor prognosis. It can be used as a prognostic marker and potential therapeutie target for AML patients.
