CTCF, a novel fusion partner of ETO2 in a post-transplant relapsed acute myeloid leukemia patient
Abstract Background ETO2 is a nuclear co-repressor, which plays a critical role in the regulation of the cell cycle, self-renewal capacity, and differentiation of hematopoietic progenitor cells. Methods We identified novel fusion transcripts involving ETO2 and CTCF by RNA-seq in a post-transplant relapsed case. Results The CTCF-ETO2 and ETO2-CTCF chimeric genes were validated by RT-PCR and Sanger sequencing. In addition, both transcripts apparently promoted cell proliferation which is beneficial to tumorigenesis. Conclusion The novel fusions may have prognostic value and pathogenic mechanisms in acute myeloid leukemia.
