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


mTORC2, mammalian target of rapamycin (mTOR) complex 2: Click to Expand ⟱
Source:
Type:
mTORC2 associates closely with the plasma membrane, and has been detected in association with ribosomal membranes (11), where it can interact with its key substrates, the AGC kinases including AKT1-3, serum glucose kinase (SGK) isoforms, and protein kinase C (PKC) family members.
Rapamycin is a known allosteric inhibitor of mTORC1, while TOR kinase inhibitors (TOR-KIs) inhibit the activities of both complexes.
AKT, a key substrate of mTORC2, is among the most commonly hyper-activated proteins in cancer. AKT integrates signals from PI3K/mTORC2 and from PI3K/PDK1 to promote cell growth and survival.
