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:
Lipid peroxidation is a chain reaction process in which free radicals (often reactive oxygen species, or ROS) attack lipids containing carbon-carbon double bonds, especially polyunsaturated fatty acids. This attack results in the formation of lipid radicals, peroxides, and subsequent breakdown products.
Lipid peroxidation can cause damage to cell membranes, leading to increased permeability and disruption of cellular functions. This damage can initiate a cascade of events that may contribute to carcinogenesis.
The byproducts of lipid peroxidation, such as malondialdehyde (MDA) and 4-hydroxynonenal (4-HNE), can form adducts with DNA, leading to mutations. These mutations can disrupt normal cellular processes and contribute to the development of cancer.
Lipid peroxidation damages cell membranes, disrupts cellular functions, and can trigger inflammatory responses. It is a marker of oxidative stress and is implicated in many chronic diseases.

Negative Prognostic Indicator: In many cancers, high levels of lipid phosphates, particularly S1P, are associated with poor prognosis, indicating a more aggressive tumor phenotype and potential resistance to therapy.
Mixed Evidence: The prognostic significance of lipid phosphates can vary by cancer type, with some studies showing that their expression may not always correlate with adverse outcomes.
