Resveratrol / TLR4 Cancer Research Results

RES, Resveratrol: Click to Expand ⟱
Features: polyphenol
Found in red grapes and products made with grapes.
Resveratrol is a polyphenol compound found in various plant species, including grapes, berries, and peanuts.
• Anti-inflammatory effects, Antioxidant effects:
- Antiplatelet aggregation for stroke prevention
- BioAvialability use piperine
- some sources may use Japanese knotweed roots (Reynoutria Japonica - root) as source which might contain Emodin (laxative)
-known as Nrf2 activator, both in cancer and normal cells. Which raises controversity of use in ROS↑ therapies. Interestingly there are reports of NRF2↑ and ROS↑ in cancer cells. This raises the question of if it is a chemosensitizer. However other reports indicate NRF2 droping with Res, indicating it maybe a chemosenstizer.
- RES is also considered to be them most effective natural SIRT1↑ -activating compound (STACs).

However, in the presence of certain metals, such as copper or iron, resveratrol can undergo a process called Fenton reaction, which can lead to the generation of reactive oxygen species (ROS). The pro-oxidant effects of resveratrol are often observed at high concentrations, typically above 50-100 μM, and in the presence of certain metals or other pro-oxidant agents. In contrast, the antioxidant effects of resveratrol are typically observed at lower concentrations, typically below 10-20 μM.

Clinical trials have used doses ranging from 150 mg to 5 grams per day. Lower doses (< 1 g/day) are often well-tolerated, but higher doses might be necessary for therapeutic effects and can be associated with side effects.

-Note half-life 1-3 hrs?.
BioAv poor: min 5uM/L required for chemopreventive effects, but 25mg Oral only yeilds 20nM. co-administration of piperine

- Selectivity: Cancer Cells vs Normal Cells

Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 Reactive oxygen species (ROS) ↑ ROS (dose- & context-dependent) ↓ ROS / buffered Conditional Driver Biphasic redox modulation Resveratrol can act as a pro-oxidant in cancer cells while functioning as an antioxidant in normal cells
2 Mitochondrial integrity / intrinsic apoptosis ↓ ΔΨm; ↑ caspase activation ↔ preserved Driver Execution of intrinsic apoptosis Mitochondrial dysfunction and apoptosis follow ROS elevation in cancer cells
3 SIRT1 / AMPK axis ↑ AMPK; context-dependent SIRT1 modulation ↑ SIRT1 / ↑ AMPK Driver Metabolic stress signaling Resveratrol modulates energy-sensing pathways affecting survival and metabolism
4 PI3K → AKT → mTOR axis ↓ AKT / ↓ mTOR ↔ adaptive suppression Secondary Growth and anabolic inhibition Downregulation of growth signaling contributes to cytostasis and apoptosis sensitization
5 NF-κB signaling ↓ NF-κB activation ↓ inflammatory NF-κB tone Secondary Suppression of survival and inflammatory transcription NF-κB inhibition contributes to reduced proliferation and invasion
6 Cell cycle regulation ↑ G1/S or G2/M arrest ↔ largely spared Phenotypic Cytostatic growth control Cell-cycle arrest reflects upstream signaling disruption
7 HIF-1α / VEGF axis ↓ HIF-1α; ↓ VEGF ↔ minimal Secondary Anti-angiogenic pressure Interference with hypoxia-driven adaptation and angiogenesis


TLR4, Toll-like receptor 4: Click to Expand ⟱
Source:
Type:
Also called CD284 (cluster of differentiation 284)
A key activator of the innate immune response and plays a central role in the fight against bacterial infections.
Accumulating evidences demonstrated that the activation of TLR4 in tumor microenvironment can not only boost the anti-tumor immunity but also give rise to immune surveillance and tumor progression. "double-edged sword” role of TLR4 activation
