Fas-associated death domain (FADD)/Mort1 was initially reported as a pro-apoptotic adaptor molecule that recruits the initiator caspases 8 and 10 to promote formation of the death-inducing signal complex (DISC) and mediates receptor induced apoptosis. Recent studies have brought to light ancillary death receptor induced apoptosis-independent activities of FADD that include cell cycle regulation, NF-κB activation, cell proliferation and role during embryonic development. We have recently shown that in lung adenocarcinomas increased FADD mRNA and protein are significantly associated with poor survival and that FADD overexpression was not due to gene amplification and/or mutation. In this study we showed that the nuclear localization of FADD and elevated expression of the phosphorylated form of FADD (p-FADD) correlated most closely with an increase in NF-κB activity and poor clinical outcome. These results suggest that levels of p-FADD may be used as a prognostic biomarker for predicting survival of lung cancer patients.
