Quercetin / AntiCan Cancer Research Results

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"

- Others: PI3K↓, AKT↓, JAK↓, STAT↓, Wnt↓, β-catenin↓, AMPK, α↓, ERK↓, JNK, - SREBP (related to cholesterol).
- Synergies: chemo-sensitization, chemoProtective, RadioSensitizer, RadioProtective, Others(review target notes), Neuroprotective, Cognitive, Renoprotection, Hepatoprotective, CardioProtective,

- Selectivity: Cancer Cells vs Normal Cells

Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 Reactive oxygen species (ROS) ↑ ROS (dose-, metal-, context-dependent) ↓ ROS Conditional Driver Biphasic redox modulation Quercetin exhibits pro-oxidant behavior in cancer cells while protecting normal cells
2 Mitochondrial integrity / intrinsic apoptosis ↓ ΔΨm; ↑ caspase activation ↔ preserved Driver Execution of intrinsic apoptosis Mitochondrial dysfunction is a central apoptosis route in cancer cells
3 PI3K → AKT → mTOR axis ↓ AKT / ↓ mTOR ↔ adaptive suppression Driver Growth and survival inhibition AKT/mTOR suppression is a consistently reported upstream effect in cancer models
4 NF-κB signaling ↓ NF-κB activation ↓ inflammatory NF-κB tone Secondary Reduced survival and inflammatory transcription NF-κB inhibition contributes to chemosensitization and apoptosis susceptibility
5 MAPK signaling (JNK / p38) ↑ JNK / ↑ p38 ↔ minimal Secondary Stress-mediated apoptosis signaling MAPK activation supports apoptosis downstream of redox stress
6 Cell cycle regulation ↑ G1/S or G2/M arrest ↔ largely spared Phenotypic Cytostatic growth control Cell-cycle arrest reflects disruption of growth signaling
7 HIF-1α hypoxia signaling ↓ HIF-1α ↔ minimal Secondary Reduced hypoxia tolerance Quercetin interferes with hypoxia-driven transcriptional programs
8 NRF2 antioxidant response ↑ NRF2 (adaptive, context-dependent) ↑ NRF2 (protective) Adaptive Stress compensation NRF2 induction reflects redox buffering rather than primary cytotoxicity
