In this study, our results demonstrated that co-treatment of CUR and BBR more strongly increased the protein levels of phosphorylated JNK and Beclin1, and decreased the phosphorylated Bcl-2, suggesting that the co-treatment activated JNK signaling pathway, leading to phosphorylation of Bcl-2 and dissociation of Beclin1, and consequently resulted in autophagic cell death in the two breast cancer cells. Here, BECN1 is linked to breast carcinoma.
