Muscadine Plus MPX. Prostate & PSA Research Links.

Men with prostate and PSA issues are interested in studies using Muscadine Plus MPX muscadine seed.

This blog post contains links to four articles which discuss the efficacy of Muscadine Plus MPX for prostate treatment.

The Muscadinex MX1 supplement (details at the end of this post) includes 325mg of the Muscadine Plus MPX powder used in the research. The powder is sourced from Muscadine Naturals of North Carolina, who hold a patent for processing muscadine grapes.

Research link #1

Muscadine Grape Skin Extract (MPX) in Men with Biochemically Recurrent Prostate (condition): A Randomized, Multicenter, Placebo-Controlled Clinical Trial.

Synopsis. "MPX (Muscadine Plus), a commercial preparation of powdered

muscadine grape skin, distributed as a dietary supplement, contains ellagic acid and its precursors, the flavonoids quercetin and epicatechin, and the stillbenoid trans-resveratrol, which have demonstrated (beneficial) activity in prostate (condition) cells in vitro.

Invasive DU145 cells treated with quercetin displayed delayed migration, depressed invasion, and inhibited capillary formation."

Research link #2

Effects of Two Doses of MPX Capsules on Rising Prostate-specific Antigen Levels in Men Following Initial Therapy for Prostate (condition).

Synopsis. "This research is being done to test an investigational product called Muscadine Plus in the treatment of men who have received initial therapy (surgery and or radiation, cryotherapy or brachytherapy) for prostate (condition) and are experiencing a rise in their prostate-specific antigens (PSA) level."

Research link #3

Muscadine Plus in Treating Rising PSA Levels in Men Carrying a Specific Gene Variant (Alanine / Alanine SOD2 Genotype) Following Initial Therapy for Prostate (condition).

Synopsis. "Each treatment cycle consists of once daily oral dosing of 4000 mg Muscadine Plus, every day throughout each 12 week (84 day) cycle. Patients may continue to receive additional cycles of study drug and will be followed every three months with standard visits with their physician until completion of 48 weeks of study treatment, disease progression, or until they wish to discontinue the drug.

Ellagic acid inhibits DNA Methyltransferase. DNA Methyltransferases (DNMTs) are a family of enzymes that regulate chromatin methylation and use S-adenosyl methionine (SAM) as the methyl donor. Ellagic acid's metabolite, urolithin-A inhibits the protein complex nuclear factor kappa-light-enhancer of activated B-cells (NFkB), potentially leading to increased rates of apoptosis and decreases in cell proliferation. Extracts from Vitis rotundifolia have shown inhibition of the phosphatidylinositol 3-kinase-Akt pathway."

Research link #4

Muscadine Plus in Treating Rising PSA Levels in Men Carrying a Specific Gene Variant (Alanine / Alanine SOD2 Genotype) Following Initial Therapy for Prostate (condition).

Synopsis. "Muscadine plus (MPX) is made from Muscadine grape skins that have been dried and ground into powder. Studies in the laboratory suggest the grape skins contain natural compounds that slow the growth of prostate (condition). About one out of every four men has the specific deoxyribonucleic acid (DNA) (Alanine / Alanine SOD2 Genotype) that might make them more responsive to MPX. Prostate specific antigen (PSA) is a protein produced by the cells of the prostate gland. PSA test can monitor patients with a history of prostate (condition) to see if the (condition) has come back. This phase III trial studies how well MPX works in treating rising prostate-specific antigen levels (PSA) in men, following initial therapy for prostate (condition) compared to those not taking MPX."
