An epithelial cell adhesion molecule (EpCAM) is a type I transmembrane protein expressed in the majority of normal epithelial tissues and overexpressed in the human epithelial cancers including breast cancer. Treatment with plant-derived anti-EpCAM mAb (mAbr COK) and Raw264. 7 cells inhibited cell growth in the human breast cancer cell line MCF -7. In MCF-7 treated with mAbr COK and Raw264.7 cells, expression of p53 and p21 increased, whereas the expression of G1 phase-related protein, cyclin D1, CDK4, cyclin E and CDK2 decreased. In addition of treatment with mAbP COK and Raw264. 7 cells decreased the expressiOn of anti-apoptotic protein Bcl-2, but the expression of pro-apoptotic proteins Bax, TNF-u, caspase-3, caspase-6 and caspase-9, increased. Moreover, cells treated with mAbr COK and Raw264. 7 cells expressed metastasis-related gangliosides GM1 and GD1a. These results suggest that mAbr COK has an effect on anti-cancer activity.
