http://purl.uniprot.org/citations/16498412 | http://www.w3.org/2000/01/rdf-schema#comment | "Notch signaling plays a critical role in T-cell differentiation and leukemogenesis. We previously demonstrated that, while pre-TCR is required for thymocytes proliferation and leukemogenesis, it is dispensable for thymocyte differentiation in Notch3-transgenic mice. Notch3-transgenic premalignant thymocytes and T lymphoma cells overexpress pTalpha/pre-TCR and display constitutive activation of NF-kappaB, providing survival signals for immature thymocytes. We provide genetic and biochemical evidence that Notch3 triggers multiple NF-kappaB activation pathways. A pre-TCR-dependent pathway preferentially activates NF-kappaB via IKKbeta/IKKalpha/NIK complex, resulting in p50/p65 heterodimer nuclear entry and recruitment onto promoters of Cyclin D1, Bcl2-A1 and IL7-receptor-alpha genes. In contrast, upon pTalpha deletion, Notch3 binds IKKalpha and maintains NF-kappaB activation through an alternative pathway, depending on an NIK-independent IKKalpha homodimer activity. The consequent NF-kappaB2/p100 processing allows nuclear translocation of p52/RelB heterodimers, which only trigger transcription from Bcl2-A1 and IL7-receptor-alpha genes. Our data suggest that a finely tuned interplay between Notch3 and pre-TCR pathways converges on regulation of NF-kappaB activity, leading to differential NF-kappaB subunit dimerization that regulates distinct gene clusters involved in either cell differentiation or proliferation/leukemogenesis."xsd:string |
