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.

4782- Lyco,    New Insights into Molecular Mechanism behind Anti-Cancer Activities of Lycopene
- Review, Var, NA
AntiCan↑, From an anti-cancer perspective, lycopene is often associated with reduced risk of prostate cancer and people often look for it as a dietary supplement which may help to prevent cancer.
TumCP↓, Lycopene was known to be able to suppress cancerous cell proliferation, migration, invasion and adhesion activity in cell culture studies.
TumCMig↓,
TumCI↓,
TumCA↓,
ROS↓, Such suppression was often observed with changes of cancer-related gene expression and relief of oxidative stress
MMP2↓, In general, lycopene could suppress the expression of MMP-2, MMP-7, MMP-9, Sp1, IGF-1R, VEGF while increasing E-cadherin stabilization, connexin 43, nm23-H1, TIMP-1 and TIMP-2 levels
MMP7↓,
MMP9↓,
VEGF↓,
E-cadherin↑,
TIMP1↑,
TIMP2↑,
BioAv↝, it is recommended to avoid consumption of lycopene concurrently with high dietary fiber intake as several types of dietary fiber were found to be able to reduce the bioavailability of lycopene
*IL12↓, lycopene could suppress proinflammatory cytokines such as IL-12, TNF-α, IL-1, IL-1β, IL-6
*TNF-α↓,
*IL1↓,
*IL1β↓,
*IL6↓,
COX2↓, Sprague Dawley rat model, lycopene treatment after induction by azoxymethane caused suppression of aberrant crypt foci, preneoplastic lesion and biomarkers such as COX-2 and iNOS expression
iNOS↓,
*radioP↑, lycopene before induction of DNA damage via X-irradiation as lycopene treatment after irradiation failed to show such DNA protective effect
NF-kB↓, anti-cancer effect of lycopene was also observed in pancreatic cancer cells (PANC-1 cell line) whereby significant reduction of ROS, NF-κB and anti-apoptotic biomarkers (cIAP1, cIAP2 and survivin) was detected while an increment of caspase-3 and Bax:
