Nuclear NPM-ALK binds to endogenous full-length NPM and FOXM1 in ALK+ ALCL cells as assessed by co-immunoprecipitation (Haque et al, 2019). Endogenous NPM1 likely bridges the interaction between NPM-ALK and FOXM1, as the FOXM1-binding region of NPM1 is not conserved in the fusion protein and NPM1-ALK has been shown to form heterodimers with NPM1 (Box et al, 2016; Khan et al, 2015; Bhat et al, 2011). Formation of this complex is required for FOXM1-dependent expression of target genes such as CCNB1 (Cyclin B1), and consistent with this, both NPM-ALK and FOXM1 are detected in complex with a biotinylated FOXM1-consensus containing DNA target in ALCL lines and bind to the CCNB1 promoter as assessed by ChIP (Haque et al, 2019).
STAT3 likely contributes to the NPM1-ALK:FOXM1 signaling axis, as lentiviral knockdown of FOXM1 decreases phosphorylation of both STAT3 and NPM1-ALK, as well as decreasing expression of CCNB1. The significance of FOXM1-dependent phosphorylation of STAT3 and NPM1-ALK remains to be clarified (Haque et al, 2019).
