| 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 Pathways: - usually induce ROS production in cancer cells, while reducing ROS in normal cells. - ROS↑ related: MMP↓(ΔΨm), ER Stress↑, UPR↑, GRP78↑, Ca+2↑, Cyt‑c↑, Caspases↑, DNA damage↑, cl-PARP↑, HSP↓, - Lowers AntiOxidant defense in Cancer Cells: NRF2(typically increased), TrxR↓**, SOD↓, GSH↓ Catalase↓ HO1↓(wrong direction), GPx↓ - Raises AntiOxidant defense in Normal Cells: ROS↓, NRF2↑, SOD↑, GSH↑, Catalase↑, - lowers Inflammation : NF-kB↓, COX2↓, p38↓, Pro-Inflammatory Cytokines : NLRP3↓, IL-1β↓, TNF-α↓, IL-6↓, IL-8↓ - inhibit Growth/Metastases : TumMeta↓, TumCG↓, EMT↓, MMPs↓, MMP2↓, MMP9↓, TIMP2, IGF-1↓, uPA↓, VEGF↓, ROCK1↓, FAK↓, RhoA↓, NF-κB↓, CXCR4↓, SDF1↓, TGF-β↓, α-SMA↓, ERK↓ - reactivate genes thereby inhibiting cancer cell growth : HDAC↓, EZH2↓, P53↑, HSP↓, Sp proteins↓, - cause Cell cycle arrest : TumCCA↑, cyclin D1↓, cyclin E↓, CDK2↓, CDK4↓, CDK6↓, - inhibits Migration/Invasion : TumCMig↓, TumCI↓, TNF-α↓, FAK↓, ERK↓, EMT↓, TOP1↓, TET1↓, - inhibits glycolysis /Warburg Effect and ATP depletion : HIF-1α↓, PKM2↓, cMyc↓, GLUT1↓, LDH↓, LDHA↓, HK2↓, PFKs↓, PDKs↓, ECAR↓, OXPHOS↓, GRP78↑, Glucose↓, GlucoseCon↓ - inhibits angiogenesis↓ : VEGF↓, HIF-1α↓, Notch↓, FGF↓, PDGF↓, EGFR↓, Integrins↓, - inhibits Cancer Stem Cells : CSC↓, CK2↓, Hh↓, CD133↓, CD24↓, β-catenin↓, sox2↓, notch2↓, nestin↓, OCT4↓, - Others: PI3K↓, AKT↓, JAK↓, STAT↓, Wnt↓, β-catenin↓, AMPK, ERK↓, JNK, - Synergies: chemo-sensitization, chemoProtective, RadioSensitizer, RadioProtective, Others(review target notes), Neuroprotective, Cognitive, Renoprotection, Hepatoprotective, CardioProtective, - Selectivity: Cancer Cells vs Normal Cells

| Cytochrome c ** The term "release of cytochrome c" ** an increase in level for the cytosol. Small hemeprotein found loosely associated with the inner membrane of the mitochondrion where it plays a critical role in cellular respiration. Cytochrome c is highly water-soluble, unlike other cytochromes. It is capable of undergoing oxidation and reduction as its iron atom converts between the ferrous and ferric forms, but does not bind oxygen. It also plays a major role in cell apoptosis. The term "release of cytochrome c" refers to a critical step in the process of programmed cell death, also known as apoptosis. In its new location—the cytosol—cytochrome c participates in the apoptotic signaling pathway by helping to form the apoptosome, which activates caspases that execute cell death. Cytochrome c is a small protein normally located in the mitochondrial intermembrane space. Its primary role in healthy cells is to participate in the electron transport chain, a process that helps produce energy (ATP) through oxidative phosphorylation. Mitochondrial outer membrane permeability leads to the release of cytochrome c from the mitochondria into the cytosol. The release of cytochrome c is a pivotal event in apoptosis where cytochrome c moves from the mitochondria to the cytosol, initiating a chain reaction that leads to programmed cell death. On the one hand, cytochrome c can promote cancer cell survival and proliferation by regulating the activity of various signaling pathways, such as the PI3K/AKT pathway. This can lead to increased cell growth and resistance to apoptosis, which are hallmarks of cancer. On the other hand, cytochrome c can also induce apoptosis in cancer cells by interacting with other proteins, such as Apaf-1 and caspase-9. This can lead to the activation of the intrinsic apoptotic pathway, which can result in the death of cancer cells. Overexpressed in Breast, Lung, Colon, and Prostrate. Underexpressed in Ovarian, and Pancreatic. |
