According to studies, Bilberry may process a unique function in blocking the formation of new blood vessels to fuel tumor growth.
Angiogenesis is the development of new blood vessels from the existing vasculature. The process has occurred throughout life in humans in the form of health and disease.
Normal angiogenesis ensures that developing or healing tissues receive an adequate supply of nutrients,
In a tumor, the availability of nutrients is limited, therefore, for the tumor to survive and grow continuously, the tumor cells induce the formation of a new blood supply from the preexisting vasculature by stimulating the protein associated with the pro-angiogenesis and facilitation of angiogenesis, such as vascular endothelial growth factor.
In other words, if we can cut off the blood vessels that provide nutrients to the tumor, we may cure cancers.
Dr. Adair TH, the lead scientists in the investigation of the angiogenesis in diseases and cancer said, "Stimulation of angiogenesis can be therapeutic in ischemic heart disease, peripheral arterial disease, and wound healing. Decreasing or inhibiting angiogenesis can be therapeutic in cancer, ophthalmic conditions, rheumatoid arthritis, and other diseases".
And, "Capillaries grow and regress in healthy tissues according to functional dem bands. Exercise stimulates angiogenesis in skeletal muscle and heart. A lack of exercise leads to capillary regression. Capillaries grow in adipose tissue during weight gain and regress during weight loss.
The results strongly suggested that by allowing or blocking the growth of new blood vessels, angiogenesis may be used as a primary target for the treatment of chronic diseases and cancers
Bilberry is a species of low-growing shrubs in the genus Vaccinium, belonging to the family Ericaceae, native to Northern Europe.
The herbal plant has been used as foods and herbs in traditional medicine for the treatment of acute and chronic diarrhea, gastritis, gastric ulcer, duodenal ulcer, enterocolitis, ulcerative colitis, anemia, cystitis, kidney disease, psoriasis, diabetes, etc.
Researchers on finding a natural compound that blocks the progression of cancer examined the anti-angiogenic activity of berry anthocyanins.
Six berry extracts (wild blueberry, bilberry, cranberry, elderberry, raspberry seeds, and strawberry) included in the study were analyzed for the anti-angiogenic (the ability to reduce unwanted growth of blood vessels, which can lead to varicose veins and tumor formation) properties.
Formula OptiBerry IH141, including all berries used in the study, demonstrated superior anti-angiogenic properties compared to the other combinations tested.
OptiBerry significantly inhibited free radical and proinflammatory cytokines in the expression of VEGF (Vascular Endothelial Growth Factor) associated with the formation of the new blood vessels.
According to the Matrigel assay using human microvascular endothelial cells, OptiBerry reduced the new blood vessel formation by impairing angiogenesis.
Furthermore, endothelioma cells pretreated with OptiBerry showed a diminished ability to form hemangioma and markedly decreased tumor growth by more than 50% through its anti-angiogenic, and anti-carcinogenic properties.
In order to reveal more information about berry's anti-angiogenic activity to prevent and treat cancer, researchers investigated the six berry extracts (wild blueberry, bilberry, cranberry, elderberry, raspberry seed, and strawberry) and a grape seed proanthocyanidin extract (GSPE) against the formation of new blood vessels for cancer proliferation.
Wild bilberry and blueberry extracts possessed the highest antioxidant activity observed by the ORAC values compared to other berries.
In other words, wild bilberry and blueberry extracts inhibited the overexpression of free radicals and proinflammatory cytokines in stimulating the production of VEGF (Vascular Endothelial Growth Factor) in enhancing angiogenesis.
Interestingly, these activities of wild bilberry and blueberry extracts were not shared by other antioxidants such as alpha-tocopherol or GSPE but were commonly shared by pure flavonoids.
Taken together, bilberry used alone or combined with other berries may be considered functional remedies for the prevention of angiogenesis and treatment of cancer cell proliferation by stimulating the formation of a new blood vessel, pending the confirmation of large sample size and multicenter human study.
