| Curcumin is the main active ingredient in Tumeric. Member of the ginger family.Curcumin is a polyphenol extracted from turmeric with anti-inflammatory and antioxidant properties. - Has iron-chelating, iron-chelating properties. Ferritin. But still known to increase Iron in Cancer cells. - GSH depletion in cancer cells, exhaustion of the antioxidant defense system. But still raises GSH↑ in normal cells. - Higher concentrations (5-10 μM) of curcumin induce autophagy and ROS production - Inhibition of TrxR, shifting the enzyme from an antioxidant to a prooxidant - Strong inhibitor of Glo-I, , causes depletion of cellular ATP and GSH - Curcumin has been found to act as an activator of Nrf2, (maybe bad in cancer cells?), hence could be combined with Nrf2 knockdown -may suppress CSC: suppresses self-renewal and pathways (Wnt/Notch/Hedgehog). Clinical studies testing curcumin in cancer patients have used a range of dosages, often between 500 mg and 8 g per day; however, many studies note that doses on the lower end may not achieve sufficient plasma concentrations for a therapeutic anticancer effect in humans. • Formulations designed to improve curcumin absorption (like curcumin combined with piperine, nanoparticle formulations, or liposomal curcumin) are often employed in clinical trials to enhance its bioavailability. -Note half-life 6 hrs. BioAv is poor, use piperine or other enhancers Pathways: - induce ROS production at high concentration. Lowers ROS at lower concentrations curcumin can act as a pro-oxidant when blue light is applied - ROS↑ related: MMP↓(ΔΨm), ER Stress↑, UPR↑, GRP78↑, Cyt‑c↑, Caspases↑, DNA damage↑, cl-PARP↑, HSP↓ - Lowers AntiOxidant defense in Cancer Cells: GSH↓ Catalase↓ HO1↓ GPx↓ but conversely is known as a NRF2↑ activator in cancer - Raises AntiOxidant defense in Normal Cells: ROS↓, NRF2↑, SOD↑, GSH↑, Catalase↑, - lowers Inflammation : NF-kB↓, COX2↓, p38↓, Pro-Inflammatory Cytokines : TNF-α↓, IL-6↓, IL-8↓ - inhibit Growth/Metastases : TumMeta↓, TumCG↓, EMT↓, MMPs↓, MMP2↓, MMP9↓, uPA↓, VEGF↓, NF-κB↓, CXCR4↓, SDF1↓, TGF-β↓, α-SMA↓, ERK↓ - reactivate genes thereby inhibiting cancer cell growth : HDAC↓, DNMT1↓, DNMT3A↓, EZH2↓, P53↑, HSP↓, Sp proteins↓, - cause Cell cycle arrest : TumCCA↑, cyclin D1↓, CDK2↓, CDK4↓, CDK6↓, - inhibits Migration/Invasion : TumCMig↓, TumCI↓, ERK↓, EMT↓, TOP1↓, TET1↓, - inhibits glycolysis /Warburg Effect and ATP depletion : HIF-1α↓, PKM2↓, cMyc↓, GLUT1↓, LDHA↓, HK2↓, PFKs↓, PDKs↓, HK2↓, ECAR↓, OXPHOS↓, GRP78↑, GlucoseCon↓ - inhibits angiogenesis↓ : VEGF↓, HIF-1α↓, Notch↓, FGF↓, PDGF↓, EGFR↓, Integrins↓, - inhibits Cancer Stem Cells : CSC↓, CK2↓, Hh↓, GLi1↓, CD133↓, CD24↓, β-catenin↓, n-myc↓, sox2↓, OCT4↓, - Others: PI3K↓, AKT↓, JAK↓, STAT↓, Wnt↓, β-catenin↓, AMPK↓, ERK↓, JNK, TrxR**, - Synergies: chemo-sensitization, chemoProtective, RadioSensitizer, RadioProtective, Others(review target notes), Neuroprotective, Cognitive, Renoprotection, Hepatoprotective, CardioProtective, - Selectivity: Cancer Cells vs Normal Cells

| It is widely accepted that there is a strong relationship between iron levels and cancer. .
Serum ferritin levels are elevated in many malignancies. Gynecological malignant tumor patients with high serum ferritin levels have significantly less survival time than patients with low or normal serum ferritin levels.
Ferritin is the primary intracellular iron-storage protein, with small amounts released into circulation. Biologically, ferritin buffers iron to prevent oxidative damage. Clinically, serum ferritin is a composite signal reflecting iron stores and inflammation.
Key point: In cancer, ferritin behaves more like an inflammatory biomarker than a pure iron marker.
In oncology, high ferritin usually reflects one or more of the following:
-IL-6–driven inflammation (acute-phase response)
-Iron sequestration (functional iron deficiency despite high ferritin)
-Tumor-associated macrophage activity
-Cell death and tissue breakdown
-Liver involvement (secondary contributor)
Thus, ferritin integrates immune activation + metabolic stress.
