| Honokiol is a Lignan isolated from bark, seed cones and leaves of trees of Magnolia species. Honokiol was traditionally used for anxiety and stroke treatment, as well as the alleviation of flu symptoms. -considered to have antioxidant properties -low oral bioavailability and difficulty in intravenous administration -the development of various formulations of honokiol, including microemulsion, liposomes, nanoparticles and micelle copolymers have successfully solved the problem of low water solubility. Pathways: -Inhibit NF-κB activation -Downregulate STAT3 signalin -Inhibiting the PI3K/Akt pathway, -Inhibition of mTOR -Influences various MAPK cascades—including ERK, JNK, and p38 -Inhibition of EGFR -Inhibiting Notch pathway (CSCs) -GPx4 inhibit -Can induce ER stress in cancer cells, which contributes to the activation of unfolded protein response (UPR) pathways -Disrupt the mitochondrial membrane potential in cancer cells. -Reported to increase ROS production in cancer cells -Can exhibit antioxidant properties in normal cells. - has some inhibitor activity but Not classified as HDAC inhibitor as weaker and may work more indirectly. - is well-known in the research community for its role in activating SIRT3 -Note half-life 40–60 minutes BioAv Pathways: - induce ROS production in cancer cells, and typically lowers ROS in normal cells - ROS↑ related: MMP↓(ΔΨm), ER Stress↑, GRP78↑, Ca+2↑, Cyt‑c↑, Caspases↑, DNA damage↑, cl-PARP↑, HSP↓ Prx - Raises 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↓, MMPs↓, MMP2↓, MMP9↓, VEGF↓, ROCK1↓, RhoA↓, NF-κB↓, CXCR4↓, ERK↓ - reactivate genes thereby inhibiting cancer cell growth : HDAC↓, EZH2↓, P53↑, HSP↓, - cause Cell cycle arrest : TumCCA↑, cyclin D1↓, cyclin E↓, CDK2↓, CDK4↓, CDK6↓, - inhibits Migration/Invasion : TumCMig↓, TumCI↓, ERK↓, EMT↓, - inhibits glycolysis and ATP depletion : HIF-1α↓, cMyc↓, GLUT1↓, LDH↓, LDHA↓, HK2↓, PDKs↓, ECAR↓, OXPHOS↓, GRP78↑, GlucoseCon↓ - inhibits angiogenesis↓ : VEGF↓, HIF-1α↓, Notch↓, EGFR↓, - inhibits Cancer Stem Cells : CSC↓, CD133↓, β-catenin↓, sox2↓, nestin↓, OCT4↓, - Others: PI3K↓, AKT↓, JAK↓, STAT↓, Wnt↓, β-catenin↓, AMPK, ERK↓, JNK, TrxR**, - Shown to modulate the nuclear translocation of SREBP-2 (related to cholesterol). - Synergies: chemo-sensitization, chemoProtective, RadioSensitizer, RadioProtective, 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. |
