QC, Quercetin: Click to Expand ⟱
Features:
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?. "quercetin paradox"

Phytochemicals (natural plant-derived compounds) that may affect CSCs:
Curcumin
— suppresses self-renewal and pathways (Wnt/Notch/Hedgehog).
Resveratrol
— shown to reduce CSC populations and sphere formation in multiple models.
Sulforaphane (from broccoli sprouts)
— reported to inhibit CSC properties and pathways; active in vitro and in vivo.
EGCG (epigallocatechin-3-gallate, green tea)
— reduces CSC markers and sphere formation in several cancer types.
Quercetin
— reported to inhibit CSC proliferation, self-renewal and invasiveness (breast, endometrial, others).
Berberine
— shown to suppress CSC “stemness” and reduce tumorigenic properties in multiple models.
Genistein (soy isoflavone)
— decreases CSC markers, sphere formation and stemness signaling in prostate/breast/other models.
Honokiol (Magnolia bark)
— shown to eliminate or suppress CSC-like populations in oral, colon, glioma models.
Luteolin
— inhibits stemness/EMT and reduces CSC markers and self-renewal in breast, prostate and other models.
Withaferin A (from Withania somnifera / ashwagandha)
— multiple preclinical reports show WA targets CSCs and reduces tumor growth/metastasis in models.
