Features:
Fisetin is a plant based flavonoid. Found in strawberries(160ug/g), apples, persimmons, onions, cucumbers, grapes.

-Note half-life 3-4hrs
- Oral BioAv low (40-50%)
Pathways:
- induce ROS production in cancer cells, but also known to reduce it.
Also a claim Fisetin-Induced Reactive Oxygen Species Production Has No Effect on Apoptosis in RCC cells
Also one claim (NAC 10-20mM levels) that NAC enhances ROS/apoptosis

Fisetin effect on Cancer Cells
Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 PI3K → AKT → mTOR axis ↓ AKT / ↓ mTOR signaling ↔ adaptive suppression Driver Loss of survival and growth signaling Fisetin consistently suppresses pro-survival PI3K/AKT signaling, supporting growth inhibition and sensitization to stress
2 NF-κB signaling ↓ NF-κB activation ↓ inflammatory NF-κB tone Driver Suppression of inflammatory survival transcription NF-κB inhibition contributes to anti-inflammatory effects and reduced tumor-supportive signaling
3 Reactive oxygen species (ROS) ↑ ROS (context- & dose-dependent) ↓ ROS Conditional Driver Biphasic redox modulation Fisetin can act as a pro-oxidant in cancer cells at higher stress/dose while remaining antioxidant in normal cells
4 Mitochondrial integrity / intrinsic apoptosis ↓ ΔΨm; ↑ caspase activation ↔ preserved Secondary Execution of intrinsic apoptosis Mitochondrial apoptosis occurs downstream of signaling and redox disruption
5 Cell cycle regulation ↑ G1 or G2/M arrest ↔ spared Phenotypic Cytostatic growth control Cell-cycle arrest reflects upstream pathway inhibition rather than direct CDK blockade
6 Senescence / senolytic action ↑ senescence clearance (senescent-like tumor/stroma subsets) ↓ senescent cell burden (selective) Secondary Selective vulnerability of senescent-like cells Fisetin is commonly described as senolytic; in cancer context this may impact tumor microenvironment and therapy-induced senescence
7 MAPK stress signaling (JNK / p38) ↑ JNK / ↑ p38 (context-dependent) ↔ minimal Secondary Stress-mediated apoptosis signaling MAPK activation often follows ROS increase and supports apoptotic signaling
8 NRF2 antioxidant response ↑ NRF2 (adaptive, context-dependent) ↑ NRF2 (protective) Adaptive Stress compensation NRF2 activation reflects redox buffering responses rather than primary cytotoxicity
9 Migration / invasion (EMT, MMP axis) ↓ migration & invasion ↔ Phenotypic Anti-metastatic phenotype Reduced EMT and protease activity limit invasive behavior downstream of signaling changes


LC3s, Autophagosome Proteins: Click to Expand ⟱
Source:
Type:
LC3s (MAP1-LC3A, B and C) are structural proteins of autophagosomal membranes, widely used as biomarkers of autophagy. Whether these three LC3 proteins have a similar biological role in autophagy remains obscure.
Protumorigenic: In many cases, especially in advanced cancers, increased autophagy (reflected by high LC3 levels) can support tumor growth by providing nutrients and promoting cell survival under stress conditions.
Antitumorigenic: Conversely, in early-stage tumors or in response to certain therapies, autophagy can act as a tumor suppressor by preventing the accumulation of damaged organelles and proteins.
