| Plant pigment (flavonoid) found in red wine, onions, green tea, apples and berries. Quercetin is thought to contribute to anticancer effects through several mechanisms: -Antioxidant Activity: -Induction of Apoptosis:modify Bax:Bcl-2 ratio -Anti-inflammatory Effects: -Cell Cycle Arrest: -Inhibition of Angiogenesis and Metastasis: (VEGF) Cellular Pathways: -PI3K/Akt/mTOR Pathway: central to cell proliferation, survival, and metabolism. -MAPK/ERK Pathway: influencing cell proliferation, differentiation, and apoptosis. -NF-κB Pathway: downregulate NF-κB -JAK/STAT Pathway: interfere with the activation of STAT3 -Apoptotic Pathways: intrinsic (mitochondrial) and extrinsic (death receptor-mediated) pathways Quercetin has been used at doses around 500–1000 mg per day Quercetin’s bioavailability from foods or standard supplements can be low. -Note half-life 11 to 28 hours. BioAv low 1-10%, poor water-solubility, consuming with fat may improve bioavialability. also piperine or VitC. Pathways: - induce ROS production in cancer cells (higher dose). Typicallys Lowers ROS in normal cells(unless it is high dose?)or depends on Redox status?.
