Lyco, Lycopene: Click to Expand ⟱
Features:
Lycopene is a naturally occurring carotenoid found predominantly in tomatoes and other red fruits and vegetables.

Antioxidant Properties:
-Lycopene is a powerful antioxidant. It helps neutralize free radicals, which can reduce oxidative stress—a factor implicated in cancer development. Possible concern about interfering with chemotherapy and radiation therapy. However this review disagrees.
Inflammation Reduction:
-Some studies suggest that lycopene may help lower levels of inflammation, another process linked to cancer progression

At supraphysiological or extremely high concentrations, lycopene may have the potential to switch from an antioxidant to a prooxidant role
-The prooxidant effect of lycopene has been observed under conditions of high oxygen tension. In vitro studies have suggested that in environments with elevated oxygen levels, lycopene might promote rather than neutralize the production of reactive oxygen species (ROS).
-The presence of metal ions (such as iron or copper) in the environment can catalyze reactions where antioxidants, including lycopene, contribute to oxidative processes. These metals can interact with lycopene, potentially leading to the formation of radicals.

The mevalonate pathway produces cholesterol and a variety of isoprenoids, which are important for maintaining cell membrane integrity, protein prenylation, and other essential cellular functions.
-One of the primary enzymes in this pathway is HMG-CoA reductase (3-hydroxy-3-methylglutaryl-coenzyme A reductase), which is the target of statin drugs used for lowering cholesterol. Some studies suggest that lycopene might downregulate the activity of HMG-CoA reductase or other enzymes in the mevalonate pathway. By doing so, lycopene could potentially reduce the synthesis of cholesterol and isoprenoids that are necessary for rapid cell proliferation—an especially relevant aspect in cancer cells.

Lycopene typically used in a 100mg/day range for cancer (inhibition of the the Melavonate Pathway)
-also has antiplatelet aggregation capability.

-Note half-life 16–20 days.
BioAv Heat processing, especially when combined with a small amount of fat, significantly enhances lycopene’s bioaccessibility and absorption. (20% under optimal conditions)
Pathways:
- ROS usually goes down, but may go up or down depending on dose and environment. Lycopene may also be modified to be a "oxdiative product" which may change the behaviour.

ROS, Reactive Oxygen Species: Click to Expand ⟱
Source: HalifaxProj (inhibit)
Type:
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.
-mitochondria is the main source of reactive oxygen species (ROS) (and the ETC is heavily related)

"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.

3534- QC,  Lyco,    Synergistic protection of quercetin and lycopene against oxidative stress via SIRT1-Nox4-ROS axis in HUVEC cells
- in-vitro, Nor, HUVECs
*ROS↓, especially quercetin-lycopene combination (molar ratio 5:1), prevented the oxidative stress in HUVEC cells by reducing the reactive oxygen species (ROS) and suppressing the expression of NADPH oxidase 4 (Nox4), a major source of ROS production.
*NOX4↓, Quercetin-lycopene combination could interact with SIRT1 to inhibit Nox4 and prevent endothelial oxidative stress
*Inflam↓, quercetin-lycopene combination downregulated inflammatory genes induced by H2O2, such as IL-17 and NF-κB.
*NF-kB↓, NF-κB p65 was activated by H2O2 but inhibited by the quercetin-lycopene combination.
*p65↓,
*SIRT1↑, quercetin and lycopene combination promoted the thermostability of Sirtuin 1 (SIRT1) and activated SIRT1 deacetyl activity
*cardioP↑, The cardioprotective role of SIRT1
*IL6↓, LYP: Q = 1:5), interacted with deacetylase SIRT1 to inhibit NF-κB p65 and Nox4 enzyme, downregulated inflammatory cytokines such as IL-6 and pro-inflammatory enzymes such as COX-2, and suppressed ROS elevation activated by H2O2.
*COX2↓,
