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:
Diablo homolog is a mitochondrial protein that in humans is encoded by the DIABLO gene on chromosome 12. DIABLO is also referred to as second mitochondria-derived activator of caspases or SMAC. This protein binds inhibitor of apoptosis proteins, thus freeing caspases to activate apoptosis.
SMAC/Diablo is known to be a pro-apoptotic protein and its overexpression has been observed to oppose progression of a variety of tumor types. SMAC/Diablo possesses a new lipid synthesis-related function essential for cancer growth, rendering SMAC/Diablo a promising therapeutic target in cancer. Suggesting that the role of SMAC/Diablo in cancer can be a double-edged sword.

High levels of Diablo expression have been associated with increased sensitivity to chemotherapy and better prognosis in some cancers, as it may promote apoptosis in cancer cells. Conversely, low levels of Diablo expression might correlate with resistance to treatment and poorer outcomes.
