Figure 1. Effects of TNF-α on cell viability, inflammatory cytokines and ERS-related molecules.

Figure 1

A. Cell viability is expressed as an OD value. B. The levels of sICAM1 in cell culture supernatants. C. Representative Western blot results showing ICAM1, MMP9, GRP78, ATF4, cleaved-caspase12, p-PERK and PERK protein expression. The results are expressed as the means ±SD, n = 6. aaP<0.01, compared with the control group; bbP<0.01, compared with the 1 ng/mL TNF-α group; ccP<0.01, compared with the 5 ng/mL TNF-α group. EP, ethyl pyruvate; OD, optical density.
