Involvement of the NF-κB pathway in the transforming properties of the TEL-Jak2 leukemogenic fusion protein

Abstract : Constitutively active tyrosine kinases are frequently expressed in various types of human leukemias as the result of chromosomal translocations. The TEL-Jak2 fusion oncoprotein possesses transforming properties in both animal and cellular models, that are tightly dependent on Stat5 activation. In the IL-3-independent TEL-Jak2-transformed Ba/F3 cells, activation of the PI-3K/Akt pathway appears essential to cell proliferation. Here we report a sustained activation of NF-kappaB factors in Ba/F3 cells, which inhibition dramatically impairs cell viability, indicating that NF-kappaB signaling exerts a major role in the anti-apoptotic activities of TEL-Jak2 oncoprotein.
