“The endocannabinoid system, comprising lipid-derived endocannabinoids, their G-protein-coupled receptors (GPCRs), and the enzymes for their metabolism, is emerging as a promising therapeutic target in cancer.
This report highlights the main signaling pathways for the antitumor effects of the endocannabinoid system in cancer and its basic role in cancerpathogenesis, and discusses the alternative view of cannabinoid receptors as tumor promoters.
We focus on new players in the antitumor action of the endocannabinoid system and on emerging crosstalk among cannabinoid receptors and other membrane or nuclear receptors involved in cancer.”
