Peripheral T cell lymphoma: new model + new insight.

The nonreceptor tyrosine kinase SYK has recently received a good deal of attention as a critical oncogene in various hematologic malignancies. A newly developed model of peripheral T cell lymphoma (PTCL) using the ITK-SYK fusion gene should serve as a powerful tool to dissect the signaling cascades important for SYK-associated malignancy in the context of t(5;9) PTCL.
