Abstract:
Objective:To investigate the expression level of urothelial carcinoembryonic antigen 1(lncRNA UCA1)in the bone marrow of acute myeloid leukemia(AML)patients,and to explore the clinical significance of lncRNA UCA1 expression level in AML patients.Methods:Bone marrow samples of 50 AML patients were collected as experimental group,and bone marrow samples of 20 iron deficiency anemia(IDA)patients were collected as control group.The relevant clinicopathological characteristics of AML patients were collected.Real-time quantitative PCR(qRT-PCR)was used to detect the expression level of lncRNA UCA1 in the experimental and control groups,and the relationships between lncRNA UCA1 expression and clinical pathological characteristics and prognosis in AML patients were analyzed.Kaplan-Meier curves were used to analyze the effect of lncRNA UCA1 on the overall survival(OS)of AML patients;And Cox regression model was used to analyze the factors affecting the prognosis of AML patients.Results:Compared with the control group,the expression level of lncRNA UCA1 was significantly elevated in patients with AML(P＜0.001);The proportion of patients with hemoglobin lower than 90 g/L in lncRNA UCA1 high expression group was significantly higher than that in lncRNA UCA1 low expression group(P=0.004);The expression level of lncRNA UCA1 was higher in M1,M2,and M4 subtypes,while it was lower in M0 and M5 subtypes,and the difference was statistically significant(P=0.009).There were no significant difference in sex,age,white blood cell(WBC)count,platelet(PLT)count,bone marrow blasts,chemotherapy regimen and efficacy,karyotype,gene mutation,and prognostic risk stratification between patients in UCA1 high expression group and those in UCA1 low expression group(all P＞0.05).The OS of patients with high expression of lncRNA UCA1 was significantly shorter than that of patients with low expression of lncRNA UCA1(P=0.0229).Conclusion:The expression level of lncRNA UCA1 is significantly upregulated in AML patients.High expression of lncRNA UCA1 is associated with poor clinicopathological features and poor prognosis.Therefore,lncRNA UCA1 can be used as a prognostic indicator and a potential therapeutic target for AML patients.
