Vitamin C Inhibits New Blood Vessel Growth to Tumors
High levels of vitamin C in the blood may help fight cancer by preventing angiogenesis, the growth of new blood vessels necessary to feed growing tumors, according to a recent report.
Fighting angiogenesis is a target of cancer therapy. Unfortunately, many existing angiogenesis inhibiors have toxic side effects, prompting scientists to seek safer, natural alternatives.
Scientists analyzed the effects of high levels of vitamin C on angiogenesis in two assasy: an ex vivo study using rat tisues and an in vivo study in mice. Both studies showed that high levels of vitamin C, obtainable through intravenous infusion, inhibited new blood vessel growth. In the in vivo assay, vitamin C-treated tissue showed 30% less blood vessel growth than un untreated tissue.
These findings complement previous research showing that high levels of the vitamin are selectively toxic to tumors in living animals. --J. Angiogenes Res. 2010 Jan. 18;2.2; P.R. Health Sci. J. 2005 June;24(2): 145-50.
