Features:
Antioxidant found in blueberries, cranberries and grapes.
Pterostilbene (trans-3,5-dimethoxy-40-hydroxystilbene) is a naturally occurring stilbene, found mainly in blueberries and grapes. It is a dimethylated derivative of resveratrol with comparable antioxidant, anti-inflammatory and anticarcinogenic properties [26].
-more bioavailable than resveratrol
-Antioxidant activity: Reduces reactive oxygen species and lipid peroxidation
-Anti-inflammatory: Downregulates pro-inflammatory cytokines- IL-1β, TNF-α, NF-κB
-Amyloid pathology:inhibits Aβ aggregation and promotes clearance- Aβ, APP, BACE1
-Reduces hyperphosphorylation of tau protein
-Inhibits histone deacetylases (HDACs)
-Increases acetylcholine by inhibiting acetylcholinesterase
-Sirtuin activation

Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 SIRT1 / AMPK metabolic sensing ↑ AMPK; context-dependent SIRT1 modulation ↑ SIRT1 / ↑ AMPK Driver Energy-stress signaling Pterostilbene strongly engages energy-sensing pathways due to high bioavailability
2 PI3K → AKT → mTOR axis ↓ AKT / ↓ mTOR ↔ adaptive suppression Driver Growth and survival inhibition AKT/mTOR suppression explains cytostatic and pro-apoptotic effects in cancer cells
3 Reactive oxygen species (ROS) ↑ ROS (mild, dose-dependent) ↓ ROS / buffered Conditional Driver Biphasic redox modulation More balanced redox profile than resveratrol; weaker pro-oxidant behavior
4 Mitochondrial integrity / intrinsic apoptosis ↓ ΔΨm; ↑ caspase activation ↔ preserved Secondary Execution of apoptosis Mitochondrial apoptosis follows metabolic and redox stress
5 NF-κB signaling ↓ NF-κB activation ↓ inflammatory NF-κB tone Secondary Suppression of inflammatory survival programs NF-κB inhibition contributes to anti-invasive and chemosensitizing effects
6 Cell cycle regulation ↑ G1 or G2/M arrest ↔ spared Phenotypic Cytostatic growth control Cell-cycle arrest reflects upstream metabolic and signaling effects
7 NRF2 antioxidant response ↑ NRF2 (adaptive) ↑ NRF2 (protective) Adaptive Redox compensation NRF2 activation contributes to stress buffering rather than primary cytotoxicity

Type:
Snail gene may show a role in recurrence of breast cancer by downregulating E-cadherin and inducing an epithelial to mesenchymal transition. Snail promotes metastasis of breast cancer cells and overexpression of Snail is a biomarker of poor clinical outcome for patients with breast cancer.
Snail, a repressor of E-cadherin and an inducer of EMT.
Snail (SNAI1):
A transcription factor that plays a key role in the regulation of the epithelial-to-mesenchymal transition (EMT).
It suppresses the expression of epithelial markers (such as E-cadherin) and upregulates mesenchymal markers, facilitating changes in cell adhesion and motility.
EMT Induction:
Snail actively represses genes such as E-cadherin, a protein critical for cell–cell adhesion. Its upregulation leads to a loss of epithelial characteristics and the acquisition of a mesenchymal phenotype, enhancing migratory potential.
Invasion and Metastasis:
Through EMT induction, Snail facilitates tumor cell dissemination and invasion into surrounding tissues, thereby playing a central role in metastasis.

Elevated levels of Snail have been observed in a variety of cancers, including breast, colorectal, pancreatic, and head and neck cancers.
Elevated Snail expression is frequently associated with a worse prognosis, including lower overall survival rates and increased likelihood of metastasis.
