Apigenin present in parsley, celery, chamomile, oranges and beverages such as tea, beer and wine. "It exhibits cell growth arrest and apoptosis in different types of tumors such as breast, lung, liver, skin, blood, colon, prostate, pancreatic, cervical, oral, and stomach, by modulating several signaling pathways." -Note half-life reports vary 2.5-90hrs?. -low solubility of apigenin in water : BioAv (improves when mixed with oil/dietary fat or lipid based formulations) -best oil might be MCT oils (medium-chain fatty acids) Pathways: - Often considered an antioxidant, in cancer cells it can paradoxically induce ROS production (one report that goes against most others, by lowering ROS in cancer cells but still effective) - ROS↑ related: MMP↓(ΔΨm), ER Stress↑, Ca+2↑, Cyt‑c↑, Caspases↑, DNA damage↑, UPR↑, cl-PARP↑, HSP↓ - Lowers AntiOxidant defense in Cancer Cells: NRF2↓, GSH↓ (Conflicting evidence about Nrf2) - Combined with Metformin (reduces Nrf2) amplifies ROS production in cancer cells while sparing normal cells. - Raises AntiOxidant defense in Normal Cells: NRF2↑, SOD↑, GSH↑, Catalase↑, - lowers Inflammation : NF-kB↓, COX2↓, p38↓, Pro-Inflammatory Cytokines : IL-1β↓, TNF-α↓, IL-6↓, IL-8↓ - inhibit Growth/Metastases : , MMPs↓, MMP2↓, MMP9↓, IGF-1↓, uPA↓, VEGF↓, ERK↓ - reactivate genes thereby inhibiting cancer cell growth : HDAC↓, DNMT1↓, DNMT3A↓, EZH2↓, P53↑, HSP↓ - cause Cell cycle arrest : TumCCA↑, cyclin D1↓, cyclin E↓, CDK2↓, CDK4↓, CDK6↓, - inhibits Migration/Invasion : TumCMig↓, TumCI↓, FAK↓, ERK↓, - inhibits glycolysis and ATP depletion : HIF-1α↓, PKM2↓, cMyc↓, PDK1↓, GLUT1↓, LDHA↓, HK2↓, Glucose↓, GlucoseCon↓ - inhibits angiogenesis↓ : VEGF↓, HIF-1α↓, PDGF↓, EGFR↓, Integrins↓, - inhibits Cancer Stem Cells : CSC↓, CK2↓, Hh↓, GLi↓, GLi1↓, - Others: PI3K↓, AKT↓, JAK↓, 1, 2, 3, STAT↓, 1, 2, 3, 4, 5, 6, Wnt↓, β-catenin↓, AMPK↓,, α↓,, ERK↓, 5↓, JNK↓, - Shown to modulate the nuclear translocation of SREBP-2 (related to cholesterol). - Synergies: chemo-sensitization, chemoProtective, RadioSensitizer, RadioProtective, Others(review target notes) -Ex: other flavonoids(chrysin, Luteolin, querectin) curcumin, metformin, sulforaphane, ASA Neuroprotective, Renoprotection, Hepatoprotective, CardioProtective, - Selectivity: Cancer Cells vs Normal Cells Apigenin exhibits biological effects (anticancer, anti-inflammatory, antioxidant, neuroprotective, etc.) typically at concentrations roughly in the range of 1–50 µM. Parsley microgreens can contain up to 2-3 times more apigenin than mature parsley. Apigenin is typically measured in the range of 1-10 μM for biological activity. Assuming a molecular weight of 270 g/mol for apigenin, we can estimate the following μM concentrations: 10uM*5L(blood)*270g/mol=13.5mg apigenin (assumes 100% bioavailability) then an estimated 10-20 mg of apigenin per 100 g of fresh weight parlsey 2.2mg/g of apigenin fresh parsley 45mg/g of apigenin in dried parsley (wikipedia) so 100g of parsley might acheive 10uM blood serum level (100% bioavailability) BUT bioavailability is only 1-5% (Supplements available in 75mg liposomal)( Apigenin Pro Liposomal, 200 mg from mcsformulas.com) A study had 2g/kg bw (meaning 160g for 80kg person) delivered a maximum 0.13uM of plasma concentration @ 7.2hrs. Assuming parsley is 90-95% water, then that would be ~16g of dried parsley Conclusion: to reach 10uM would seem very difficult by oral ingestion of parsley. Other quotes: “4g of dried parsley will be enough for 50kg adult” 5mg/kg BW yields 16uM, so 80Kg person means 400mg (if dried parsley is 130mg/g, then would need 3g/d) In many cancer cell lines, concentrations in the range of approximately 20–40 µM have been reported to shift apigenin’s activity from mild antioxidant effects (or negligible ROS changes) toward a clear pro-oxidant effect with measurable ROS increases. Low doses: At lower concentrations, apigenin is more likely to exhibit its antioxidant properties, scavenging ROS and protecting cells from oxidative stress. In normal cells with robust antioxidant systems, apigenin’s antioxidant effects might prevail, whereas cancer cells—often characterized by an already high level of basal ROS—can be pushed over the oxidative threshold by increased ROS production induced by apigenin. In environments with lower free copper levels, this pro-oxidant activity is less pronounced, and apigenin may tilt the balance toward its antioxidant function. |

Tumor cell cycle arrest refers to the process by which cancer cells stop progressing through the cell cycle, which is the series of phases that a cell goes through to divide and replicate. This arrest can occur at various checkpoints in the cell cycle, including the G1, S, G2, and M phases.
S, G1, G2, and M are the four phases of mitosis. |
