They found that pre-treatment with LY294002, a PI3K inhibitor, enhanced curcumin-induced autophagy and apoptosis by modifying Bcl-2 expression and subsequent autophagosome formation in MCF-7 breast cancer cells [36]. In vivo effect of curcumin and its derivative (2E,6E)-2,6-bis(4-hydroxy-3-methoxybenzylidene)cyclohexanone (BHMC) had been checked on 4T1 (triple-negative breast cancer cell line) breast cancer cells challenged mice. Here, PIK3CA is linked to breast cancer.
