Fig. 4From: Synergistic anticancer activity of cisplatin combined with tannic acid enhances apoptosis in lung cancer through the PERK-ATF4 pathwayThe expression of related factors by endoplasmic reticulum stress in CDDP and TA-treated H1299 cells. CDDP treatment combined with TA induced the expression of GRP78, CHOP, PERK, ATF4, IRE1α, XBP1, ATF6, CHOP, Cleaved-caspase3, Pro-caspase3 at the protein level in H1299 cells.Back to article page
