CASP3 and cervical cancer: A previous study has confirmed that quercetin has the following effects: induces endoplasmic reticulum stress in cervical cancer HeLa cells; induces the expression of GRP78; activates the increased expression of caspase-3, CHOP, IRE1, p-PERK and c-ATF6; reduces the expression of Bcl-2; induces cell apoptosis; and inhibits the viability of cervical cancer cells [63].
