Genetics and Epigenetics of the TET-ETS Translocation Network

摘要

In the present paper we review the translocation network involving TET and ETS family members with special focus on the Ewing family of tumors. FUS (fusion, involved in t(12;16) in malignant liposarcoma = TLS, Translocated in liposarcoma), EWSR1 (Ewing sarcoma breakpoint region 1) and TAF15 (TATA box-binding protein-associated factor, 68-KD) are the three human members of the TET family of RNA binding proteins. In addition, two EWSR1 pseudogenes are present in the human genome. TET family members are involved in several oncogenic gene fusions. Five of the 18 known fusion partners belong to the E26 (E twenty-six, ETS) family of transcription factors. Gene fusions between TET or ETS family members and other fusion partners link these gene fusions to a large network of oncogenic gene rearrangements.
