Figure 7. Effect of Thapsigargin and TRAIL co-treatment on ERS signaling in human ESCC cells (24 h).

Representative Western blot results of p-PERK, GRP78, CHOP, p-eIF2α, and ATF4 are shown. Membranes were re-probed for β-actin expression to show that similar amounts of protein were loaded in each lane. The results are expressed as the mean ± SD; n = 6.^aP < 0.05 vs. the control group in EC109 cells, ^abP < 0.05 vs. the control group in TE12 cells.
