Background
The Friend leukemia virus integration 1 (FLI1) protein is a transcription factor containing an ETS DNA-binding domain and is highly expressed in hematopoietic cell lineages and vascular endothelial cells (1). FLI1 plays important roles in megakaryocytic differentiation (2) and vascular homeostasis (3). The FLI1 gene can undergo a t(11;22)(q24;q12) translocation with the Ewing sarcoma gene on chromosome 22, which results in a fusion gene that is present in the majority of Ewing sarcoma cases. (4). Abnormal expression of FLI1 can be used as an adverse prognostic indicator for acute myeloid leukemia (5).
