Quercetin / MMPs 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"

- 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


MMPs, Matrix metalloproteinases: Click to Expand ⟱
Source:
Type:
Family of zinc-dependent proteolytic enzymes that play a key role in degrading the extracellular matrix (ECM).; are metalloproteinases that are calcium-dependent zinc-containing endopeptidases;[1] other family members are adamalysins, serralysins, and astacins. The MMPs belong to a larger family of proteases known as the metzincin superfamily.[2]
MMP secretion: matrix metalloproteinase (MMP) is a kind of enzymes secreted.
by tumor cell to degrade ECM, facilitating the migration of tumor cells.

MMPs are generally considered protumorigenic due to their role in promoting tumor invasion, metastasis, and angiogenesis. They facilitate the breakdown of the extracellular matrix, allowing cancer cells to invade surrounding tissues and spread to distant sites.
