Quercetin / BAX 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"
- ROS↑ related: MMP↓(ΔΨm), ER Stress↑, UPR↑, GRP78↑, Ca+2↑, Cyt‑c↑, Caspases↑, DNA damage↑, cl-PARP↑, HSP↓, Prx,

- 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

BAX, Apoptosis regulator BAX: Click to Expand ⟱

Source:

Type: Proapototic protein

BAX is a member of the Bcl-2 gene family.
Pro-apoptotic protein that forms heterodimers with anti-apoptotic BCL2 proteins; involved in various cellular activities and regulated by p53; mediates the release of cytochrome c from mitochondria.
