Deletion of TRADD sensitizes to DNA damage agents-induced cell death. (a) TRADD+/+ (WT) and TRADD−/− (KO) MEFs were treated with H2O2 for 24 hours and then cell viability was analyzed by MTT assay. **P < 0.01; ***P < 0.001 (Student’s t-test). (b) TRADD+/+ (WT), TRADD−/− (KO), and TRADD−/− mTRADD (KO-TRADD) cells were treated with H2O2 for 24 hours. Cell viability was analyzed by MTT assay. *P < 0.05; ***P < 0.001 (Student’s t-test). (c) Representative images from treatment with DNA-damaging agents in TRADD wild type and knockout MEFs. TRADD+/+ (WT) and TRADD−/− (KO) MEFs were treated with doxorubicin (Doxo) and etoposide (Etopo) for 24 hours and then cell viability was analyzed by MTT assay. **P < 0.01 (Student’s t-test). (d) Representative images rescued with TRADD WT, KO, KO (NES), or KO (Src) in knockout MEFs of TRADD. MTT assay of TRADD WT, KO, KO (NES), and KO (Src) MEFs treated with H2O2 and TNF (30 ng/mL) plus CHX (2.5 μg/mL) for 24 hours. *P < 0.05; **P < 0.01; n.s., not significant (Student’s t-test).
