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.

UPR, Unfolded Protein Response: Click to Expand ⟱
Source:
Type:
Cellular stress response related to the endoplasmic reticulum (ER) stress, which involves protein folding, quality control, and signaling pathways. The unfolded protein response (UPR) is the cells' way of maintaining the balance of protein folding in the endoplasmic reticulum. (UPR) is triggered by the presence of misfolded proteins in the endoplasmic reticulum.
The UPR is a cellular stress response activated by the accumulation of unfolded or misfolded proteins in the endoplasmic reticulum (ER).
- It is primarily mediated by three ER-resident sensors: IRE1α, PERK, and ATF6.

Cancer cells often experience high levels of protein synthesis, hypoxia, nutrient deprivation, and oxidative stress, all of which can activate the UPR.
– Numerous studies have reported that key UPR components (e.g., GRP78/BiP, IRE1α, PERK, CHOP) are overexpressed in various malignancies such as breast, pancreatic, lung, and prostate cancers.

Unfolded Protein Response is typically upregulated in cancers and is associated with poorer prognosis due to its role in promoting cell survival, adaptation to stress, and therapeutic resistance. Although the UPR harbors the potential for tumor-suppressive (apoptotic) effects under severe stress conditions, its predominant activation in tumors supports an adaptive, protumorigenic state that facilitates cancer progression. Targeting UPR components and modulating this balance remain promising therapeutic strategies.
