| Hydrogen Gas, Powerful Antioxidant Mechanistically, H₂ is most defensibly framed as a selective antioxidant + anti-inflammatory signaling modulator (often via Nrf2↑ and NF-κB↓ / NLRP3↓), with strongest clinical relevance in oncology being reduction of treatment toxicities (radiation/CCRT side-effects), with mixed/early evidence for direct anticancer effects. 1.Antioxidant and Nrf2/ARE Pathway: activate Nrf2, which induces antioxidant enzymes. 2.NF-κB Pathway: reported to inhibit NF-κB activation, thereby reducing inflammatory cytokine production 3.Mitochondrial Apoptosis Pathway 4.MAPK (Mitogen-Activated Protein Kinases) Pathway 5.PI3K/Akt/mTOR Pathway 6.Inflammatory Cytokine Signaling: Reducing cytokines (such as IL-6, TNF-α) 7.p53 Pathway 8.Autophagy Pathways: might regulate autophagy, (dual roles in cancer) Example unit sometimes used in studies Example Canadian Supplier Hydrogen gas can be generated in small amount by hydrogenase of certain members of the human gastrointestinal tract microbiota from unabsorbed carbohydrates in the intestine through degradation and metabolism, which then is partially diffused into blood flow and released and detected in exhaled breath, indicating its potential to serve as a biomarker. Many studies have shown that H2 therapy can reduce oxidative stress. This, however, contradicts radiation therapy and chemotherapy, in which ROS are required to induce apoptosis and combat cancer. Yet many studies show chemoprotective and radioprotective and some even show chemosentizing Nevertheless there are some papers claiming ROS ↑ for cancer cells Hydrogen Gas in Water is also used. - the amount of H2 dissolved in solutions is limited: up to 0.8 mM (1.6 mg/L) H2 can be dissolved in water under atmospheric pressure at room temperature

| 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. |
