In 2001, Inhibition of Glioma Growth in Vivo by Selective Activation of the CB₂ Cannabinoid Receptor

BACKGROUND: Here we show that local administration of the selective CB₂ agonist JWH-133 at 50 μg/day to Rag-2^−/− mice induced a considerable regression of malignant tumors generated by inoculation of C6 glioma cells.  Cannabinoid receptor expression was subsequently examined in biopsies from human astrocytomas
