ALK+ anaplastic large cell lymphomas (ALCL) contain cytotoxic granules that express high levels of the serine protease Granzyme B (GZMB) and the pore-forming protein Perforin (PFR1) (Foss et al, 1996; d'Amore et al, 2007). Expression of GZMB is activated downstream of NPM1-ALK through the binding of AP-1 transcription factor JUNB to its cognate site in the promoter, as assessed by electrophoretic mobililty shift assay (Pearson et al, 2011). Consistent with this, mutation of the JUNB-B binding sites or knockdown of JUNB or NPM1-ALK abrogate expression of GZMB RNA or a GZMB reporter gene in ALCL cell lines (Pearson et al, 2011).
