RESUMO
OBJECTIVE@#To study the expression of the Fra-1 gene in the peripheral blood of children with Wilms tumor and its clinical significance.@*METHODS@#Fifty children pathologically diagnosed with Wilms tumor between December 2012 and January 2018 were enrolled as the case group, and 40 healthy children for physical examination were selected as the control group. Among the 45 children with Wilms tumor who were followed up, the children with continuous remission were included in the ideal efficacy group (n=33), and those with recurrence, metastasis or death were included in the poor efficacy group (n=12). Peripheral blood samples were collected from all subjects. Quantitative real-time PCR was used to measure the mRNA expression of Fra-1.@*RESULTS@#The case group had significantly higher mRNA expression of Fra-1 in peripheral blood than the control group (P0.05). The mRNA expression of Fra-1 was significantly lower in the ideal efficacy group than in the poor efficacy group (P<0.05).@*CONCLUSIONS@#Fra-1 may be involved in the development of Wilms tumor and plays a certain role in its development, invasion and metastasis, but the mechanism remains to be further studied.
