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


HSP27, Heat shock protein 27: Click to Expand ⟱
Source:
Type: Protein
Heat Shock Protein 27 (Hsp27), also known as HSPB1, is a small heat shock protein that plays a crucial role in cellular stress responses, protein folding, and protection against apoptosis.
Hsp27 is involved in various cellular processes, including the stabilization of proteins, regulation of the cytoskeleton, and modulation of signaling pathways.
Acts as a protein chaperone and an antioxidant and plays a role in the inhibition of apoptosis and actin cytoskeletal remodeling. Plays a key role in anti-cancer treatment resistance, inhibition of apoptosis and tumor progression. HSP27 is upregulated in many cancers and is associated with a poor prognosis.

Expression in Cancers: Hsp27 is often overexpressed in various types of cancers, including breast, prostate, lung, and colorectal cancers. Its expression can be induced by stressors such as heat shock, oxidative stress, and exposure to certain chemotherapeutic agents.
Prognostic Implications: The expression levels of Hsp27 have been associated with cancer prognosis. In many studies, high levels of Hsp27 expression correlate with poor prognosis, increased tumor aggressiveness, and resistance to chemotherapy.
