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 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.

Reactive oxygen species (ROS) are highly reactive molecules that contain oxygen and can lead to oxidative stress in cells. They play a dual role in cancer biology, acting as both promoters and suppressors of cancer. ROS can cause oxidative damage to DNA, leading to mutations that may contribute to cancer initiation and progression. So normally you want to inhibit ROS to prevent cell mutations. However excessive ROS can induce apoptosis (programmed cell death) in cancer cells, potentially limiting tumor growth. Chemotherapy typically raises ROS. "Reactive oxygen species (ROS) are two electron reduction products of oxygen, including superoxide anion, hydrogen peroxide, hydroxyl radical, lipid peroxides, protein peroxides and peroxides formed in nucleic acids 1. They are maintained in a dynamic balance by a series of reduction-oxidation (redox) reactions in biological systems and act as signaling molecules to drive cellular regulatory pathways." "During different stages of cancer formation, abnormal ROS levels play paradoxical roles in cell growth and death 8. A physiological concentration of ROS that maintained in equilibrium is necessary for normal cell survival. Ectopic ROS accumulation promotes cell proliferation and consequently induces malignant transformation of normal cells by initiating pathological conversion of physiological signaling networks. Excessive ROS levels lead to cell death by damaging cellular components, including proteins, lipid bilayers, and chromosomes. Therefore, both scavenging abnormally elevated ROS to prevent early neoplasia and facilitating ROS production to specifically kill cancer cells are promising anticancer therapeutic strategies, in spite of their contradictoriness and complexity." "ROS are the collection of derivatives of molecular oxygen that occur in biology, which can be categorized into two types, free radicals and non-radical species. The non-radical species are hydrogen peroxide (H 2O 2 ), organic hydroperoxides (ROOH), singlet molecular oxygen ( 1 O 2 ), electronically excited carbonyl, ozone (O3 ), hypochlorous acid (HOCl, and hypobromous acid HOBr). Free radical species are super-oxide anion radical (O 2•−), hydroxyl radical (•OH), peroxyl radical (ROO•) and alkoxyl radical (RO•) [130]. Any imbalance of ROS can lead to adverse effects. H2 O 2 and O 2 •− are the main redox signalling agents. The cellular concentration of H2 O 2 is about 10−8 M, which is almost a thousand times more than that of O2 •−". "Radicals are molecules with an odd number of electrons in the outer shell [393,394]. A pair of radicals can be formed by breaking a chemical bond or electron transfer between two molecules." Recent investigations have documented that polyphenols with good antioxidant activity may exhibit pro-oxidant activity in the presence of copper ions, which can induce apoptosis in various cancer cell lines but not in normal cells. "We have shown that such cell growth inhibition by polyphenols in cancer cells is reversed by copper-specific sequestering agent neocuproine to a significant extent whereas iron and zinc chelators are relatively ineffective, thus confirming the role of endogenous copper in the cytotoxic action of polyphenols against cancer cells. Therefore, this mechanism of mobilization of endogenous copper." > Ions could be one of the important mechanisms for the cytotoxic action of plant polyphenols against cancer cells and is possibly a common mechanism for all plant polyphenols. In fact, similar results obtained with four different polyphenolic compounds in this study, namely apigenin, luteolin, EGCG, and resveratrol, strengthen this idea. Interestingly, the normal breast epithelial MCF10A cells have earlier been shown to possess no detectable copper as opposed to breast cancer cells [24], which may explain their resistance to polyphenols apigenin- and luteolin-induced growth inhibition as observed here (Fig. 1). We have earlier proposed [25] that this preferential cytotoxicity of plant polyphenols toward cancer cells is explained by the observation made several years earlier, which showed that copper levels in cancer cells are significantly elevated in various malignancies. Thus, because of higher intracellular copper levels in cancer cells, it may be predicted that the cytotoxic concentrations of polyphenols required would be lower in these cells as compared to normal cells." Majority of ROS are produced as a by-product of oxidative phosphorylation, high levels of ROS are detected in almost all cancers. -It is well established that during ER stress, cytosolic calcium released from the ER is taken up by the mitochondrion to stimulate ROS overgeneration and the release of cytochrome c, both of which lead to apoptosis. Note: Products that may raise ROS can be found using this database, by: Filtering on the target of ROS, and selecting the Effect Direction of ↑ Targets to raise ROS (to kill cancer cells): • NADPH oxidases (NOX): NOX enzymes are involved in the production of ROS. -Targeting NOX enzymes can increase ROS levels and induce cancer cell death. -eNOX2 inhibition leads to a high NADH/NAD⁺ ratio which can lead to increased ROS • Mitochondrial complex I: Inhibiting can increase ROS production • P53: Activating p53 can increase ROS levels(by inducing the expression of pro-oxidant genes) • Nrf2: regulates the expression of antioxidant genes. Inhibiting Nrf2 can increase ROS levels • Glutathione (GSH): an antioxidant. Depleting GSH can increase ROS levels • Catalase: Catalase converts H2O2 into H2O+O.

Inhibiting DJ-1 can increase ROS levels • PARK2: regulates the expression of antioxidant genes. Inhibiting PARK2 can increase ROS levels • SIRT1:regulates the expression of antioxidant genes. Inhibiting SIRT1 can increase ROS levels • AMPK: regulates energy metabolism and can increase ROS levels when activated. • mTOR: regulates cell growth and metabolism. Inhibiting mTOR can increase ROS levels • HSP90: regulates protein folding and can increase ROS levels when inhibited. • Proteasome: degrades damaged proteins.
