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

Source:
Type:
RAD51 is a protein that plays a crucial role in the repair of DNA double-strand breaks through homologous recombination (HR). It is a key component of the DNA repair machinery and is essential for maintaining genome stability.
RAD51 expression has been correlated with other biomarkers of DNA repair and genomic instability, such as BRCA1 and BRCA2.
