Icariin
-
Cancers mentioned: General anti-cancer potential, including breast and liver cancers.
-
Food Occurrences: Found in the herb Epimedium (commonly known as Horny Goat Weed). Not typically present in standard conventional foods.
-
Summary of the Topic: Icariin is a flavonoid that has gained attention for its ability to regulate the cell cycle and induce apoptosis in various cancer cell lines. It functions by modulating oxidative stress pathways and inhibiting proliferative signaling like PI3K/Akt and MAPK.
-
Recent research focuses on its derivative, Icaritin, which has shown significant clinical potential in treating advanced hepatocellular carcinoma by enhancing the tumor immune response. It is increasingly studied for its role in preventing the epithelial-mesenchymal transition (EMT), a critical process in cancer metastasis.

Remainder of Report & Sources:
-
Mechanisms: Inhibition of tumor proliferation, promotion of pro-apoptotic proteins, and immune checkpoint modulation.

-
Primary Food Sources: Horny Goat Weed (Epimedium).
-
Molecular Targets: Modulates the PI3K/Akt and NF-κB signaling pathways. It is unique for its ability to promote bone morphogenetic protein (BMP), which can be useful in treating bone-metastatic cancers.
-
Bioavailability: Low oral absorption; often metabolized into Icaritin, which may actually be the more potent anti-cancer form.

Curcumin (via Curcumol): Recent 2024 studies show icariin and curcumol (a turmeric derivative) synergistically induce Ferroptosis in prostate cancer cells.
