Peripheral T-cell lymphomas (PTCL) are agressive lymphomas engineered mouse models and spontaneous PTCL models were that develop from mature T cells. The most common PTCLs are used to functionally examine the role of Notch signaling, and genetically, molecularly, and clinically diverse and are generally Notch1/Notch2 blockade and pan-Notch blockade using domiassociated with dismal outcomes. While Notch signaling plays a nant-negative MAML significantly impaired the proliferation of critically important role in both the development of immature T malignant T cells and PTCL progression in these models. Treatment cells and their malignant transformation, its role in PTCL is poorly with DLL1/DLL4 blocking antibodies established that Notch sigunderstood, despite the increasingly appreciated function of Notch naling is ligand-dependent. Together, these findings reveal a role for in regulating t...

Neoplasms originating from thymic T-cell progenitors and post-thymic mature T-cell subsets account for a minority of lymphoproliferative neoplasms. These T-cell derived neoplasms, while molecularly and genetically heterogeneous, exploit transcription factors and signaling pathways that are critically important in normal T-cell biology, including those implicated in antigen-, costimulatory-, and cytokine-receptor signaling. The transcription factor GATA-3 regulates the growth and proliferation of both immature and mature T cells and has recently been implicated in T-cell neoplasms, including the most common mature T-cell lymphoma observed in much of the Western world. Here we show that GATA-3 is a proto-oncogene across the spectrum of T-cell neoplasms, including those derived from T-cell progenitors and their mature progeny, and further define the transcriptional programs that are GATA-3 ...
