| Outline of Final Research Achievements |
The TAZ/CAMTA1 or YAP/TFE3 fusion genes have been identified in epithelioid hemangioendothelioma (EHE). However, the detailed function of TAZ/CAMTA1 and YAP/TFE3 on cell growth or motility remains unclear. To investigate the biological roles of these fusion proteins in EHE, we generated lentivirus mediated TAZ/CAMTA1 or YAP/TFE3 expression system in HMEC1 cells, and analyzed the changes in cell growth, motility, and the interacting proteins with fusion protein using a tandem affinity purification with LC-MS/MS. Fusion proteins were localized in the nucleus, whereas TAZ and YAP proteins preferentially found in the cytoplasm. Expression of TAZ/CAMTA modestly increased cell proliferation and motility. Using tandem affinity purification coupled with LC-MS/MS, we identified several TAZ/CAMTA-associated proteins, such as ERG, SIR7, AHNK. Our results will provide new insights into development of EHE, and give some clues to developing a new molecular target therapy for EHE.
