“Cannabinoids, the active ingredients in marijuana, restrict the sprouting of blood vessels to brain tumors by inhibiting the expression of genes needed for the production of vascular endothelial growth factor (VEGF).
“Blockade of the VEGF pathway constitutes one of the most promising antitumoral approaches currently available,” said Manuel Guzmán, professor of biochemistry and molecular biology, with the Complutense University in Madrid, Spain, and the study’s principal investigator.
“The present findings provide a novel pharmacological target for cannabinoid-based therapies.””
