Quercetin induces transcriptional expression of ERS-related factors PERK, eIF2α, ATF4, and CHOP, while transcriptional expression of the apoptosis-related factors Bax, caspase-3, and cyt-c is also significantly upregulated, and transcriptional expression of the anti-apoptotic protein Bcl-2 is markedly inhibited; this cumulatively suggests that quercetin induces cervical cancer cell apoptosis via ERS (133). Here, DDIT3 is linked to cervical carcinoma.
