| 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. EMIQ bioavialability is about 3X that of Quercetin (Example Natural Factors brand) Isoquercitrin is high bioaviability and efficiacy but at this time does not seem available as supplement. -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?.

| Interleukin-6 (IL-6) is a cytokine that plays a significant role in inflammation and the immune response. It is produced by various cell types, including T cells, B cells, macrophages, and fibroblasts. IL-6 can promote tumor cell proliferation and survival. Many cancer cells produce IL-6, which can create an autocrine loop that supports their growth. IL-6 is a high-value inflammatory biomarker in cancer, reporting cytokine burden, catabolic stress, and STAT3-linked survival signaling. While not tumor-specific, elevated and rising IL-6 strongly predicts poor prognosis and limited treatment tolerance, making it an important system-state indicator alongside CRP and ferritin. |
