SMARCA4/2 loss inhibits chemotherapy-induced apoptosis by restricting IP3R3-mediated Ca2+ flux to mitochondria

SMARCA4/2 loss in ovarian and lung cancers is associated with chemotherapy resistance. Here, the authors show that SMARCA4/2 deficiency in cancer cells reduces the expression of the ER-Ca2+ channel IP3R3 and subsequently calcium transfer to the mitochondria, which inhibits apoptotic cell death.
