Induction of Endoplasmic Reticulum Stress Pathway by Green Tea Epigallocatechin-3-Gallate (EGCG) in Colorectal Cancer Cells: Activation of PERK/p-eIF2α/ATF4 and IRE1α

Figure 2

Percentage of HT-29 viable cells. EGCG treatments were given to HT-29 cells at 24 h, 48 h, and 72 h incubation times. The MTT assay was then performed at each incubation time. The results are expressed as mean percentage ± standard error of the mean (SEM) ().
