| 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?.

| Slug is well known to promote tumor progression and metastasis through the epithelial-mesenchymal transition (EMT), causing loss of cell adhesion and polarity while conferring migratory and invasive properties. Slug/SNAI2: A transcription factor that belongs to the Snail family. It is best known for its role in regulating epithelial-to-mesenchymal transition (EMT). Expression: Upregulation of Slug in cancers is often associated with the induction of EMT. This causes cells to lose epithelial markers (like E-cadherin) and gain mesenchymal markers, leading to increased invasiveness. Metastatic Spread: By promoting EMT, high levels of Slug facilitate tumor cell dissemination and metastasis. Cancer Stem Cells: There is evidence suggesting that EMT, spurred by factors like Slug, can increase the proportion of cancer stem cells (CSCs). These CSCs are thought to be key players in tumor recurrence and maintenance. General Trend: High Slug expression in various cancers (including breast, colorectal, head and neck, and others) is frequently correlated with a more aggressive phenotype and poorer clinical outcomes. |
