| 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

| (Also known as Hsp32 and HMOX1) HO-1 is the common abbreviation for the protein (heme oxygenase‑1) produced by the HMOX1 gene. HO-1 is an enzyme that plays a crucial role in various cellular processes, including the breakdown of heme, a toxic molecule. Research has shown that HO-1 is involved in the development and progression of cancer. -widely regarded as having antioxidant and cytoprotective effects -The overall activity of HO‑1 helps to reduce the pro‐oxidant load (by degrading free heme, a pro‑oxidant) and to generate molecules (like bilirubin) that can protect cells from oxidative damage Studies have found that HO-1 is overexpressed in various types of cancer, including lung, breast, colon, and prostate cancer. The overexpression of HO-1 in cancer cells can contribute to their survival and proliferation by: Reducing oxidative stress and inflammation Promoting angiogenesis (the formation of new blood vessels) Inhibiting apoptosis (programmed cell death) Enhancing cell migration and invasion When HO-1 is at a normal level, it mainly exerts an antioxidant effect, and when it is excessively elevated, it causes an accumulation of iron ions. A proper cellular level of HMOX1 plays an antioxidative function to protect cells from ROS toxicity. However, its overexpression has pro-oxidant effects to induce ferroptosis of cells, which is dependent on intracellular iron accumulation and increased ROS content upon excessive activation of HMOX1. -Curcumin Activates the Nrf2 pathway leading to HO‑1 induction; known for its anti‑inflammatory and antioxidant effects. -Resveratrol Induces HO‑1 via activation of SIRT1/Nrf2 signaling; exhibits antioxidant and cardioprotective properties. -Quercetin Activates Nrf2 and related antioxidant pathways; contributes to anti‑oxidative and anti‑inflammatory responses. -EGCG Promotes HO‑1 expression through activation of the Nrf2/ARE pathway; also exhibits anti‑inflammatory and anticancer properties. -Sulforaphane One of the most potent natural HO‑1 inducers; triggers Nrf2 nuclear translocation and upregulates a battery of phase II detoxifying enzymes. -Luteolin Induces HO‑1 via Nrf2 activation; may also exert anti‑inflammatory and neuroprotective effects in various cell models. -Apigenin Has been reported to induce HO‑1 expression partly via the MAPK and Nrf2 pathways; also known for anti‑inflammatory and anticancer activities. |
