(8) Grape Seed Extract Induces Apoptotic Death of Human Prostate Carcinoma; Carcinogenesis. (Nov. 2002) - Our studies showed that GSE inhibits growth and induces apoptotic death of human prostrate cells. Prostate cancer chemoprevention is an alternative and potential strategy to control this malignancy.
(9) Grape Seed Extract Hopeful in Human Acute Myeloid Leukaemia; Anticancer research (2009 Jan; 29) - Aaccording to a study published in the January 2009 issue of "Clinical Cancer Research", Grape seed extract induces the programmed cell death of human leukemia cells in the laboratory by activating the enzymes of the apoptosis pathways. An additional study published in the March 2005 issue of the "Chinese Medical Journal" also reported that grape seed extract promotes the death of human acute myeloid leukemia cells in the laboratory.
(10) Grape Seed Extract and Other Grape-Based Products Anticancer and Cancer Chemopreventive Potential; The Journal of Nutrition (Dec 8 2008) - Grapes and grape-based products are in a class of dietary products that have shown cancer chemopreventive potential and are also known to improve overall human health. Overall, completed studies from various scientific groups conclude that both grapes and grape-based products are excellent sources of various anticancer agents and their regular consumption should thus be beneficial to the general population.
(11) Grape Seed Extract has Antibacterial Properties; J. of Toxicol Sci. (2010) - The considerable antibacterial activity of commonly available grape seed extract could signify a major advancement in the treatment of MRSA diseases. This study was conducted to measure the antibacterial activity of grape (Vitis vinifera L; Vitaceae) seed extract against methicillin-resistant Staphylococcus aureus (MRSA).
(12) Grape Seed Extract (Polyphenols) Able to Inhibit Amyloid-beta (Abeta) Aggregation in Alzheimer’s; Neurotox Res. (2009 Jan.15) – This study suggests that polyphenol-rich GSE prevents the Abeta deposition and attenuates the inflammation in the brain, this is promising in delaying development of AD.
(13) Grape Seed Extract Reduces Inflammation to in Obesity and Type 2 Diabetics thus Reducing Heart Disease; J. Nutr. Biochem (Oct. 21 2010) Grape Seed Extract significantly improved markers of inflammation and glycaemia and a sole marker of oxidative stress in obese Type 2 diabetic subjects at high risk of cardiovascular events over a 4-week period, which suggests it may have a therapeutic role in decreasing cardiovascular risk.
(14) Grape Seed Extract Show Promising Anti-HIV Effects; Biological (2002) – This study suggests the anti-HIV-1 effects of grape seed extracts maybe useful in the prevention and/or amelioration of HIV-1 infection.
(15) Grape Seed Extract for Control of Human Enteric Viruses and Hepatitis A; Appl Environ Microbiol.(Jun. 2011) - The results of this study indicate that Grape Seed Extract shows promise for application in the food industry as an inexpensive novel natural alternative to reduce viral contamination and enhance food safety.
