- Fig. 7 BIRD-2-triggered apoptosis is reduced by depleting the ER Ca 2+ store in SU-DHL-4 cells. a Analysis of the cytosolic Ca 2+ response in SU-DHL-4 cells using Fura-2 AM. After the addition of 3 mM EGTA, 1 or 10 uM TG or 10 uM CPA were added to deplete the ER Ca 2+ store. The curves represent the mean +- SEM of three independent experiments. The TG/CPA-releasable Ca 2+ is quantified by measuring the AUC ( F 340 / F 380 x s), which is shown in b . c Representative scatter plots from flow cytometry analysis detecting apoptosis in SU-DHL-4 cells stained with Annexin V-FITC and 7-AAD. Cells were pre-treated with or without 1 uM TG 30 min prior to application of 10 uM BIRD-2. After 2 h of BIRD-2 treatment, apoptotic cell death was detected by measuring the Annexin V-FITC-positive fraction. d Quantitative analysis of five independent experiments detecting apoptosis in SU-DHL-4 cells treated for 2 h with 10 uM BIRD-2, with or without a pre-treatment of 30 min with 1 uM TG. e Quantitative analysis of five independent experiments detecting apoptosis in SU-DHL-4 cells treated for 2 h with 10 uM BIRD-2, with or without a pre-treatment of 30 min with 10 uM CPA. f A representative western blot of four independent experiments showing the expression levels of total eIF2alpha and p-eIF2alpha in SU-DHL-4 cells treated for 4 h with 5ug/ml tunicamycin.

- Fig 2 Temporal evaluation of eIF2alpha phosphorylation in HeLa and C33A grown in tryptophan-free media. HeLa and C33A cells were plated in complete media, which was replaced with tryptophan-free media 24 hours post-plating. Cells were harvested every 6 hours and used to make extracts that were evaluated by immunoblot using antibodies against eIF2alpha or eIF2alpha phosphorylated on serine 51 (p-eIF2alpha). Immunoblots against beta-actin were performed as a loading control. Similar results were obtained from three independent experiments.
