| Chrysin is found in passion flower and honey. It is a flavonoid. -To reach plasma levels that might more closely match the concentrations used in in vitro studies (typically micromolar), considerably high doses or advanced delivery mechanisms would be necessary. Chrysin is widely summarized as modulating PI3K/Akt and MAPK pathways in cancer. Chrysin — Chrysin is a naturally occurring flavone-class flavonoid found in honey, propolis, passionflower, and several plants. Its oncology relevance is mainly preclinical: it shows multi-pathway anticancer activity in cell and animal models, but native oral chrysin has very poor systemic bioavailability and no established approved oncology use. Primary mechanisms (ranked):
Bioavailability / PK relevance: Native oral chrysin has very poor systemic exposure because of low aqueous solubility, extensive intestinal/hepatic glucuronidation and sulfation, and efflux; human oral bioavailability has been reported as extremely low, often summarized as below 1%. Formulation strategies such as nanoparticles, lipid systems, micelles, cyclodextrins, or structural analogues are commonly proposed for systemic translation. In-vitro vs systemic exposure relevance: Most anticancer studies use micromolar in-vitro concentrations that are unlikely to be reached in plasma after ordinary oral chrysin. Local intestinal exposure may be more plausible than systemic tumor exposure, but systemic anticancer claims should be treated as formulation-dependent. Clinical evidence status: Preclinical. Evidence is strong enough for mechanistic oncology interest in cell and animal models, including combination/sensitization studies, but there is no mature clinical oncology evidence establishing therapeutic benefit. -Note half-life 2 hrs, BioAv very poor often <1%Pathways: Graphical Pathways - may induce ROS production - ROS↑ related: MMP↓(ΔΨm), ER Stress↑, UPR↑, GRP78↑, Ca+2↑, Cyt‑c↑, Caspases↑, DNA damage↑, cl-PARP↑, HSP↓ - May Lower AntiOxidant defense in Cancer Cells: NRF2↓, GSH↓ HO1↓ - May Raise AntiOxidant defense in Normal Cells: ROS↓, NRF2↑, SOD↑, GSH↑, Catalase↑, - lowers Inflammation : NF-kB↓, COX2↓, Pro-Inflammatory Cytokines : IL-1β↓, TNF-α↓, IL-6↓, - inhibit Growth/Metastases : TumMeta↓, TumCG↓, EMT↓, MMP2↓, MMP9↓, TIMP2, uPA↓, VEGF↓, ROCK1↓, FAK↓, RhoA↓, NF-κB↓, ERK↓ - reactivate genes thereby inhibiting cancer cell growth : HDAC↓, P53↑, HSP↓, - cause Cell cycle arrest : TumCCA↑, cyclin D1↓, CDK2↓, CDK4↓, - inhibits Migration/Invasion : TumCMig↓, TumCI↓, FAK↓, ERK↓, EMT↓, TOP1↓, TET1↓, - inhibits glycolysis and ATP depletion : HIF-1α↓, cMyc↓, GLUT1↓, LDH↓, HK2↓, PDKs↓, HK2↓, GRP78↑, GlucoseCon↓ - inhibits angiogenesis↓ : VEGF↓, HIF-1α↓, Notch↓, PDGF↓, EGFR↓, - Others: PI3K↓, AKT↓, STAT↓, Wnt↓, AMPK↓, ERK↓, JNK, TrxR, - Synergies: chemo-sensitization, chemoProtective, RadioSensitizer, Others(review target notes), Neuroprotective, Cognitive, Renoprotection, Hepatoprotective, CardioProtective, - Selectivity: Cancer Cells vs Normal Cells Chrysin Mechanistic Profile

| A key component of the enzyme telomerase, which is responsible for maintaining the length of telomeres at the ends of chromosomes. In most somatic cells, telomerase activity is low or absent, leading to progressive telomere shortening with each cell division, which eventually triggers cellular senescence or apoptosis. many cancer cells exhibit reactivation of telomerase, primarily through the upregulation of hTERT. This reactivation allows cancer cells to maintain their telomere length, enabling them to divide indefinitely and contributing to the immortality characteristic of cancer cells. The expression of hTERT is often associated with various types of cancer, including melanoma, breast cancer, and lung cancer. | Cancer context | TERT biomarker | Clinical use | | -------------- | ----------------------------- | ---------------------------------------- | | Glioma | Promoter mutation | **WHO classification, prognosis** | | Thyroid cancer | Promoter mutation | **Aggressiveness, recurrence risk** | | Melanoma | Promoter mutation | Risk stratification | | Bladder cancer | Promoter mutation (urine DNA) | **Noninvasive detection & surveillance** | | HCC | Promoter mutation | Early event, prognosis | Why TERT Is Valuable Despite Limited “Actionability” -Telomere maintenance is mandatory for long-term tumor survival -TERT activation is often an early, irreversible event -Its presence signals a tumor that has escaped replicative limits -That makes TERT one of the best markers of “point-of-no-return” biology. |
