Angiogenesis is the process that promotes the formation of new blood vessels involving many factors including the migration, growth, and differentiation of endothelial cells.
Believe it or not, all active tissues in the body is on a distance less than a hundred micrometers from a blood capillary formed by the process of angiogenesis.
The Genentech in the article "Tumor Angiogenesis and the VEGF Pathway" wrote, "Angiogenesis is a necessary part of the process in the progression of cancer from small, localized neoplasms to larger, growing, and potentially metastatic tumors. To grow beyond 1 to 2 mm in diameter, a tumor needs an independent blood supply, which is acquired by the expression of growth factors that recruit new vasculature from existing blood vessels".
"This process continues even as the tumor matures. Thus, upregulation of angiogenesis is a key step in sustained tumor growth and may also be critical for tumor metastasis".
Angiogenesis is important for the cells for the diffusion exchange of nutrients and metabolites through the small blood vessels.
In normal and healthy condition, stimulating angiogenesis has been found to have a therapeutic effect for the treatment of ischemic heart disease, peripheral arterial disease, and wound healing.
However, in cancers, stimulating angiogenesis in tumor cells has been associated with tumors proliferation and metastasis.
In other words, angiogenesis process a function of a double sword, on one hand, the process provides an ideal condition for diseases and wound healing. On the other hand, it promotes invasive and overgrowth tumor.
In other words, by the inhibiting the process of blood vessels formation of the tumor, cancer may be curable.
In the chick chorioallantoic membrane, injection of alliin exerted a significant effect on the inhibition of fibroblast growth factor-2 (FGF2) associated with the angiogenesis.
In the CAM model, alliin also inhibited the vascular endothelial growth factor (VEGF)-induced angiogenesis.
Combined with antioxidant vitamins C and E significantly (P < 0.001) enhanced the function of alliin inhibitory efficacy on FGF2-induced EC tube formation and angiogenesis, particularly in the colon and fibrosarcoma tumor growth.
Alliin (S-allyl-L-cysteine-S-oxide) is a phytochemical compound sulfoxide,. a derivative of the amino acid cysteine, belonging to the class of sulfur compounds, found abundantly in fresh garlic and onion.
In the urgency to find a potential ingredient for the treatment of cancer with no side effect, scientists examined the phytochemical alliin, a compound derived from garlic anti-angiogenesis activity.

Combined with antioxidant vitamins C and E significantly (P < 0.001) enhanced the function of alliin inhibitory efficacy on FGF2-induced EC tube formation and angiogenesis, particularly in the colon and fibrosarcoma tumor growth.
More precisely, alliin significantly inhibited both FGF2 and VEGF secretion from human fibrosarcoma cells compared to other types of tumors in a concentration-dependent manner
In other words, alliin worked synergistically with other antioxidants to promote anti-angiogenesis and anticancer efficacy.
However, the anti-angiogenesis of alliin was reversed if the NO synthesis inhibitor nitro-L-arginine methyl ester (L-NAME) were injected.
The efficacy of alliin was attributed to the activation of the expression of a protein involved in immune tumor suppression.
Dr. Mousa AS, the lead scientist wrote, "These data also suggest the implication of cellular NO and p53 as mediators of anti-angiogenesis and anticancer effects of alliin".
Taken altogether, alliin may be considered supplements for the inhibition of angiogenesis in the promotion of tumor growth, pending on the confirmation of the larger sample size and multicenter human study.
