| 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. -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

| Hypoxia-Inducible-Factor 1A (HIF1A gene, HIF1α, HIF-1α protein product) -Dominantly expressed under hypoxia(low oxygen levels) in solid tumor cells -HIF1A induces the expression of vascular endothelial growth factor (VEGF) -High HIF-1α expression is associated with Poor prognosis -Low HIF-1α expression is associated with Better prognosis -Functionally, HIF-1α is reported to regulate glycolysis, whilst HIF-2α regulates genes associated with lipoprotein metabolism. -Cancer cells produce HIF in response to hypoxia in order to generate more VEGF that promote angiogenesis Key mediators of aerobic glycolysis regulated by HIF-1α. -GLUT-1 → regulation of the flux of glucose into cells. -HK2 → catalysis of the first step of glucose metabolism. -PKM2 → regulation of rate-limiting step of glycolysis. -Phosphorylation of PDH complex by PDK → blockage of OXPHOS and promotion of aerobic glycolysis. -LDH (LDHA): Rapid ATP production, conversion of pyruvate to lactate; HIF-1α Inhibitors: -Curcumin: disruption of signaling pathways that stabilize HIF-1α (ie downregulate). -Resveratrol: downregulate HIF-1α protein accumulation under hypoxic conditions. -EGCG: modulation of upstream signaling pathways, leading to decreased HIF-1α activity. -Emodin: reduce HIF-1α expression. (under hypoxia). -Apigenin: inhibit HIF-1α accumulation. |
