摘要：

Knock-in models of tumor-specific chromosomal translocations can generate Lethal mutations. To circumvent this, a new conditional gene fusion model has been developed (invertor mice) and exemplified with the Ews-ERG fusion oncogene. An ERG segment, flanked by loxP sites, was knocked in to an intron of the Ews gene but in an inverted transcription orientation and lineage-specific Ews-ERG fusion created by Cre-mediated inversion. This invertor method is a completely conditional approach, applicable to any gene fusion, to emulate effects of translocations found in human cancers.
