Abstract

We previously showed that methyl-F-anandamide, a stable analogue of the anandamide, inhibited the growth and the progression of cultured human breast cancer cells. As accumulating evidences indicate that the constitutive activation of the canonical Wnt pathway in human breast cancer may highlight a key role for aberrant activation of the β-catenin-TCF cascade and tumour progression, we studied the anandamide effect on the key elements of Wnt pathway in breast cancer cells. In this study we described that the treatment of human breast cancer cells, MDA MB 231 cells, with methyl-F-anandamide reduced protein levels of β-catenin in the cytoplasmic and nuclear fractions inhibiting the transcriptional activation of T Cell Factor (TCF) responsive element (marker for β-catenin signalling). The anandamide treatment resulted in up-regulation of epithelial markers, like E-cadherin with a concomitant decrease in protein levels of mesenchymal markers, including vimentin and Snail1. We, furthermore, observed that the induction of experimental epithelial-mesenchymal transition by exposure to adriamycin in MCF7 human breast cancer cell line was inhibited by anandamide treatment. In the present study we reported a novel anticancer effect of anandamide involving the inhibition of epithelial-mesenchymal transition, a process triggered during progression of cancer to invasive state.
