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


XIAP, X-linked inhibitor of apoptosis protein (XIAP) baculoviral IAP repeat-containing protein 4 (BIRC4): Click to Expand ⟱
Source:
Type:
Also known as BIRC4. XIAP is inhibited by DIABLO (Smac) and HTRA2 (Omi), two death-signaling proteins released into the cytoplasm by the mitochondria.
High proportions of XIAP may function as a tumor marker. In developing prostate cancer, XIAP is one of four IAPs overexpressed in the prostatic epithelium.

XIAP functions predominantly as a protumorigenic protein in the context of cancer. Its upregulation is commonly observed in various tumor types and is associated with poor patient outcomes and resistance to therapy due to its potent inhibition of apoptosis.
