Transcription profiling by array of human mucosa-associated lymphoid tissue lymphoma with chromosomal translocation (11;18)

ABSTRACT: Comparison of t(11;18)-positive MALT lymphoma to t(11;18)-negative MALT lymphoma, with a special focus on the NF-KB pathway and it's targets 8 t(11;18)-negative and 6 t(11;18)-positive cases of MALT lymphoma, as well as six spleen control samples (1 mix of spleens and 5 singular spleen samples)

Proper regulation of nuclear factor κB (NF-κB) transcriptional activity is required for normal lymphocyte function, and deregulated NF-κB signaling can facilitate lymphomagenesis. We demonstrate that the API2-MALT1 fusion oncoprotein created by the recurrent t(11;18)(q21;q21) in mucosa-associated lymphoid tissue (MALT) lymphoma induces proteolytic cleavage of NF-κB-inducing kinase (NIK) at arginine 325. NIK cleavage requires the concerted actions of both fusion partners and generates a C-termina  ...[more]
