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


iNOS, Inducible nitric oxide synthase: Click to Expand ⟱
Source: HalifaxProj(block)
Type:
An enzyme that produces nitric oxide (NO) in response to inflammatory stimuli.
iNOS can promote tumor growth by enhancing blood flow and nutrient supply to tumors through vasodilation. It may also help cancer cells evade apoptosis (programmed cell death).
Immune Activation: In some contexts, NO produced by iNOS can enhance the immune response against tumors, promoting the activation of immune cells that can target and destroy cancer cells.
Inhibition of Tumor Growth: High levels of NO can induce cytotoxic effects on tumor cells, leading to reduced proliferation and increased apoptosis.
