Researchers say the cannabinoids found in marijuana may aid in brain tumor treatment by targeting the genes needed for the tumors to sprout blood vessels and grow.
Their study showed that cannabinoids inhibited genes needed for the production of vascular growth factor (VEGF) in laboratory mice with glioma brain tumors and two patients with late-stage glioblastoma multiforme, a form of brain cancer.
VEGF is a protein that stimulates blood vessels to grow. Tumors need an abundant blood supply because they generally grow rapidly. So when VEGF is blocked, tumors starve from lack of blood supply and nutrients.
Blocking of VEGF constitutes one of the most promising tumor-fighting approaches currently available, says researcher Manuel Guzman, professor of biochemistry and molecular biology, at the Complutense University in Madrid, Spain, in a news release.”
