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)

Type:
The Rho GTPases RhoA, Rac1, and Cdc42 are important regulators of cytoskeletal dynamics. small GTPase Ras homolog gene family member A (RHOA)
RHOA: Ras homolog family member A
Many in vitro and in vivo data indicate tumor-promoting effects of activated Rho GTPases, also tumor suppressive functions have been described.
In many cancers, RhoA and RhoC are often found to be overexpressed.
RhoB expression can be downregulated in certain cancers, which may contribute to tumor progression. Unlike RhoA and RhoC, RhoB is often considered a tumor suppressor, and its loss can lead to increased cell proliferation and survival.
-RhoA activity has been linked to the modulation of EMT, influencing both the disassembly of cell–cell junctions and the reorganization of the cytoskeleton necessary for migration.
-Elevated levels or hyperactivation of RhoA has been associated with poor prognosis in several cancers.

1713- Lyco,    Lycopene: A Potent Antioxidant with Multiple Health Benefits
- Review, Nor, NA
*antiOx↑, As one of the most potent antioxidants, its capacity to neutralise singlet oxygen is double that of ?-carotene, ten times greater than that of ?-tocopherol, and one hundred and twenty-five times more effective than glutathione
*ROS⇅, lycopene acts as an antioxidant in systems that produce singlet oxygen but behaves as a pro-oxidant in systems that create peroxide
*Dose↝, In low doses, it acts as an antioxidant, but at high doses, it acts as a pro-oxidant
*eff↑, In situation where there is an imbalance between antioxidant defences and ROS production, such as during inflammation or exposure to environmental toxins [91], lycopene may switch from its antioxidant role to a pro-oxidant role
*LDL↓, Wistar rats given a high-fat diet and 50mg/kg body weight of lycopene daily for 3mths had significant reductions in plasma total cholesterol, triglycerides, and lLDL levels but increased HDL cholesterol
*RenoP↑, shown to protect the kidney against chemically induced damage
*Inflam↓, evidence is plentiful demonstrating the anti-inflammatory effects of lycopene both in vitro and in vivo
neuroP↑, mice with Alzheimer's disease induced by ? amyloid, lycopene reduced oxidative stress, decreased neuronal loss, improved synaptic plasticity, and inhibited neuroinflammation
Rho↓, lycopene treatment was demonstrated to have the potential to mitigate vascular arteriosclerosis in allograft transplantation by inhibiting Rho-associated kinases


* indicates research on normal cells as opposed to diseased cells
