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


p65, RelA: Click to Expand ⟱
Source:
Type:
P65, also known as RelA, is a subunit of the NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells) transcription factor complex. NF-κB plays a crucial role in regulating immune response, inflammation, and cell survival.
Due to its role in cancer progression, p65 and the NF-κB pathway are considered potential therapeutic targets. Inhibitors of NF-κB signaling are being explored in preclinical and clinical studies as potential cancer treatments.
Many studies have reported that p65 is overexpressed in various types of cancers, including breast, prostate, lung, and colorectal cancers.
In some cancers, elevated p65 levels correlate with higher grades of tumors and advanced stages of disease.

"RELA proto-oncogene, NF-κB subunit." It encodes the p65 protein, which is a central component of the NF‑κB transcription factor complex.
-Chronic activation of RELA and the NF‑κB pathway is frequently associated with cancer progression, promoting inflammation-driven tumorigenesis, chemoresistance, and metastasis.
-RELA interacts with other oncogenic signaling networks (for example, STAT3 and MAPK pathways), further integrating environmental signals that favor cancer progression.

RELA (p65) is a critical subunit of the NF‑κB transcription factor complex, involved in the regulation of genes that control inflammation, cell survival, and proliferation. In the context of cancer, aberrant activation and overexpression of RELA are frequently associated with aggressive tumor behavior, therapy resistance, and poorer patient outcomes in cancers such as breast, lung, colorectal, and pancreatic cancers, among others.

RELA emerges as a potential key contributor to the suppression of glycolysis, mitochondrial respiration, and ATP production in cancer cells. (RELA knockdown signifcantly reduced the tumorigenic.
potential of various pancreatic cancer cell lines).
