   This presentation is on the latest research in the
    areas of longevity, cancer, and heart disease.

   Claims are not being made to treat disease or health
    conditions with dietary supplements.

   This research is in its infancy; please refrain from
    drawing conclusions based on preliminary data.
    Berry and Fruit Extracts to be Discussed

   Resveravine® – whole grape extract containing

   BioVin® Advanced – grape skin extract
    containing OPCs, anthocyanins, and resveratrol

   Vita Blue® – wild blueberry extract containing

    synergistic biological effects of trans-resveratrol and -

   A standardized extract with 20% total trans-
    resveratrol and  -viniferin

   The most concentrated source of Resveratrol
               Resveratrol is naturally produced by
               plants as a defense system against
               infection and oxidative stress due to
               external attacks.

    (programmed cell death) in         health
    unhealthy cells                     Normal platelet activity

   Promotes normal activity of        Diabetes
    the SIRT-1 gene (involved in
    calorie restriction, fat
    mobilization, mitochondrial
    function, longevity)

   Apoptosis is programmed cell death. The lifespan
    of cells have genetic limitations. The apoptotic
    process safely disposes of old cells and cell
    fragments and does not trigger inflammation.
 Microscope View of Apoptosis
A. Unfertilized embryonic cell receives a biochemical signal to die.
B. Cell starts to shrink as activated enzymes cut up the cytoskeleton and
   DNA in the nucleus.
C. Cell prepares itself to be engulfed by macrophages.
D. Cell fragments into blobs.
       Apoptosis is a Normal Process

   Rapid turnover of white blood cells in the body
   Remodeling of the developing fetus (fingers and
   Formation of connections (synapses) between
    neurons in the brain
   Menstruation – sloughing of the uterine lining
           Apoptosis in Cancer Cells

   Unlike normal cells, cancer cells proliferate rapidly
    and lose the ability to respond to cell death signals
    and apoptosis. Resveratrol has been found to
    inhibit proliferation and induce apoptosis in a
    number of cancer cell lines.

            Importance of Apoptosis

   Defective cell cycle regulation may result in
    the propagation of mutations that
    contribute to the development of cancer.
    Resveratrol has been found to induce cell
    cycle arrest when added to cancer cells
    grown in culture.

    response to infection.
   Incorrect regulation of NF-κB has been linked to

   Resveratrol was shown to be a potent inhibitor of NF-kB by blocking
    IkB kinase activity

    Resveratrol Inflammation Research

   Cyclooxygenase (COX) – Blocking this enzyme impedes the
    production of the chemical messengers (prostaglandins) that
    cause pain and swelling from inflammation.

   Suppression of COX-2 expression by blocking the activation of MAPKs
    and AP-1 may represent possible molecular mechanisms responsible
    for previously reported anti-tumor promoting effects of resveratrol on
    mouse skin carcinogenesis.
       Biofactors. 21(1-4):33-39, 2004.

   Study concluded in addition to other effects on gene expression,
    resveratrol also directly inhibited the activity of COX-2.

           Resveratrol Inhibits Platelet
   Platelet aggregation is one of the first steps in the
    formation of a blood clot that can occlude a
    coronary or cerebral artery, resulting in myocardial
    infarction or stroke. Resveratrol has been found to
    inhibit platelet aggregation in vitro.
   Blood Cells Mol Dis. 2000;26(2):144-150.
   Clin Chim Acta. 1995;235(2):207-219.
      Resveratrol stimulates eNOS

   eNOS is an enzyme that catalyzes the formation of
    nitric oxide (NO) by vascular endothelial cells. NO is
    needed to maintain arterial relaxation (vasodilation),
    and impaired NO-dependent vasodilation is
    associated with increased risk of cardiovascular
    disease. Resveratrol has been found to stimulate
    eNOS activity in cultured endothelial cells.

               Caloric Restriction

   Caloric restriction is reducing caloric intake
    without malnutrition.

   Proven method for extending life span (30-
    50%) and postponing age-related functional
    decline and age-related disease.
Resveratrol Research in Extending
            Life Span
   Restricting calorie intake extends the life spans of
    organisms ranging from yeast cells to lab animals.
   Sirtuins enhance cell survival during times of stress,
    especially lack of food.
   Sirtuins are regulators of aging in virtually all living
   Resveratrol activates sirtuin activity without the
    extreme difficulty of starving oneself!
         Sirtuins Help Cells Survive

   Sirtuins help rejuvenate old or dying cells by
    beefing up their DNA repair process and
    stimulating production of protective

   If a cell is at a point of deciding whether to
    live or die, Sirtuins push toward the survival
    mode by making the cell fix itself.

            Activation of Sirtuins
   Tests on Nothobranchius furzeri, a short-lived seasonal fish
     Resveratrol extended the maximum life span by 59% and

Resveratrol is a Superior Antioxidant

   Oxidative stress is implicated in numerous disease processes

   A lead resveratrol investigator, Dr. Milos Sovak commented, “There is
    no question that resveratrol is one of the best free-radical scavengers
    and that it has many effects whose ramifications might affect not only
    longevity but also general health.”
    Resveratrol as an Antioxidant

   In vitro studies revealed that red wine
    extract is a potent antioxidant as
    evidenced by its ability to scavenge
    peroxyl radical in vitro.

    Resveratrol Might Fight Obesity

   June 16th. Google: “Martin Wabitsch endo08

   Human fat cells exposed to resveratrol or not
    exposed (control).

   Number of fat cells in control doubled.
    Number of fat cells exposed to resveratrol
    decreased by 50%.
    Resveratrol Might Fight Obesity

   In addition, exposure to resveratrol also
    reduced the secretion of substances called
    interleukin 6 and 8, which may be linked to
    the development of diabetes and clogged
    arteries, both thought to be obesity-related
                Safety of Resveratrol

   Data in humans have revealed that resveratrol is safe to ingest.

      therapy of cancer: preclinical and clinical studies. Anticancer
      Res. 24(5A):2783-840, 2004.

   Human trials on Resveravine®
     Single oral doses of 1, 2.5 and 5 grams were given to 29

      volunteers, and no serious adverse events were reported.
      Possible Herb-Drug Interactions

   Resveratrol has been found to inhibit human
    platelet aggregation in vitro. Theoretically, high
    intakes of resveratrol (e.g., from supplements)
    could increase the risk of bleeding when taken
    with anticoagulant drugs, such as warfarin
    (Coumadin), and antiplatelet drugs, such as
    clopidogrel (Plavix), dipyridamole (Persantine),
    non-steroidal anti-inflamatory drugs (NSAIDs),
    aspirin and others.
As mentioned, Resveravine also provides  -Viniferin,
which is a dimer of Resveratrol :

                    Naturally synthesized by the plant, it is
                    involved in the defense system against
                    various fungi such as Botrytis cinerea .
                    It is naturally present in the grapes and

                     Like Resveratrol,  -Viniferin has also very
                     interesting biological properties:

                            • anti-inflammatory
                            • antioxidant effects

   Hypoxia             OXYGEN

 But HIF Can’t Help the Cancer Cells Survive When
Antioxidants Have Neutralized All The Free Radicals.

Conclusions about Berry Extracts and
Cell Health
   The active chemicals in selected berries have
    shown promise in maintaining cardiovascular,
    immune, and visual health, as well as lengthening
    life span and using fat stores more efficiently in
    experimental animal models.
   The active chemicals are more than potent
    antioxidants – they interact with key enzymes and
    signaling pathways in cells.
   Research is ongoing. More to come….
