Death receptor-induced cell death and endoplasmic reticulum stress. (A) Caspase 8 activity measured using ELISA, and RIP 1 and 3 expression examined through western blotting. (B) Caspase 12 activity measured using ELISA, and CHOP and ATF-4 expression analyzed through western blotting. The uncropped western blot images are shown in Fig. S3. Data are expressed as the means ± SD of 3 independent experiments for the caspase 12 assay, and 4 independent experiments for all other assays. *P < 0.05 and **P < 0.01 versus the negative control.
