Intriguingly, anandamide (AEA), a cannabinoid receptor 1 (CB1) agonist, inhibits cholangiocarcinoma growth through activation of the non-canonical Wnt pathway mediated by Wnt5A8 and, in human breast cancer cells, methyl-F-AEA reduces β-Catenin levels, inhibits the transcriptional activation of TCF responsive elements and decreases the expression of mesenchymal markers9. The gene discussed is CNR1; the disease is breast cancer.
