| Vitexin - Apigenin-8-C-Glucoside Alternative Names: Apigenin-8-C-glucoside, apigenin-8-C-β-D-glucopyranoside Type: Flavone C-glycoside / apigenin derivative Function: Vitexin is a naturally occurring C-glycosylated flavone in which glucose is attached to apigenin at the C-8 position. It exhibits antioxidant, anti-inflammatory, metabolic, cardiovascular, neuroprotective, and antiproliferative activities and can modulate pathways involving NF-κB, Nrf2/HO-1, MAPK, PI3K/AKT, AMPK, HIF-1α, apoptosis, and oxidative stress. -see also IsoVitexinCancer: Preclinical studies indicate antiproliferative, pro-apoptotic, anti-migratory, anti-invasive, and anti-inflammatory effects across multiple cancer models. Reported mechanisms include modulation of PI3K/AKT, MAPK, NF-κB, HIF-1α, ROS, apoptosis, and cell-cycle signaling. Clinical anticancer efficacy has not been established. Alzheimer's Disease: Preclinical evidence suggests neuroprotective activity through antioxidant and anti-inflammatory effects, reduction of neuronal injury, regulation of oxidative stress and mitochondrial function, and modulation of signaling pathways relevant to cognitive impairment and amyloid-associated neurotoxicity. Clinical efficacy for Alzheimer's disease has not been established. |

| 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. |
