| (Also known as Hsp32 and HMOX1) HO-1 is the common abbreviation for the protein (heme oxygenase‑1) produced by the HMOX1 gene. HO-1 is an enzyme that plays a crucial role in various cellular processes, including the breakdown of heme, a toxic molecule. Research has shown that HO-1 is involved in the development and progression of cancer. -widely regarded as having antioxidant and cytoprotective effects -The overall activity of HO‑1 helps to reduce the pro‐oxidant load (by degrading free heme, a pro‑oxidant) and to generate molecules (like bilirubin) that can protect cells from oxidative damage Studies have found that HO-1 is overexpressed in various types of cancer, including lung, breast, colon, and prostate cancer. The overexpression of HO-1 in cancer cells can contribute to their survival and proliferation by: Reducing oxidative stress and inflammation Promoting angiogenesis (the formation of new blood vessels) Inhibiting apoptosis (programmed cell death) Enhancing cell migration and invasion When HO-1 is at a normal level, it mainly exerts an antioxidant effect, and when it is excessively elevated, it causes an accumulation of iron ions. A proper cellular level of HMOX1 plays an antioxidative function to protect cells from ROS toxicity. However, its overexpression has pro-oxidant effects to induce ferroptosis of cells, which is dependent on intracellular iron accumulation and increased ROS content upon excessive activation of HMOX1. -Curcumin Activates the Nrf2 pathway leading to HO‑1 induction; known for its anti‑inflammatory and antioxidant effects. -Resveratrol Induces HO‑1 via activation of SIRT1/Nrf2 signaling; exhibits antioxidant and cardioprotective properties. -Quercetin Activates Nrf2 and related antioxidant pathways; contributes to anti‑oxidative and anti‑inflammatory responses. -EGCG Promotes HO‑1 expression through activation of the Nrf2/ARE pathway; also exhibits anti‑inflammatory and anticancer properties. -Sulforaphane One of the most potent natural HO‑1 inducers; triggers Nrf2 nuclear translocation and upregulates a battery of phase II detoxifying enzymes. -Luteolin Induces HO‑1 via Nrf2 activation; may also exert anti‑inflammatory and neuroprotective effects in various cell models. -Apigenin Has been reported to induce HO‑1 expression partly via the MAPK and Nrf2 pathways; also known for anti‑inflammatory and anticancer activities. |
| In Alzheimer's disease (AD), cholinergic dysfunction (often with reduced acetylcholine tone and impaired choline metabolism) is linked with cortical dysfunction, memory deficit, abnormal cerebral blood flow, task learning difficulty, sleep-cycle disruption, and neurodevelopmental effects (context-dependent). CORE HALLMARKS / HIGH-CONFIDENCE AXES: - tau and Aβ, their accumulation in AD brains is known to be a major hallmark. In AD, PP2A↓ activity is decreased (reported), contributing to hyperphosphorylated tau accumulation. SIRT-1↓ levels in AD brains are associated with accumulation of Aβ and tau (reported). - glucose metabolism↓ (brain glucose hypometabolism) occurs in AD long before significant clinical signs in many cohorts/models (reported). - Neuroinflammation / lipid mediator tone (reported): 5-LOX↑ and PGE2↑ (model-/region-dependent). - Synaptic vulnerability (reported): PSD95↓ in hippocampus and cortex; restoring PSD95 shows cognitive benefits in models. - Clearance/transport imbalance (reported): IDE↓, NEP↓, LRP1↓, and AEP↑ protein levels in AD brains (reported). COMMONLY REPORTED DIRECTIONAL CHANGES (model/region/compartment dependent): - Monoamines (reported): concentrations of 5-HTP↓, 5-HT(seratonin)↓, and 5-HIAA↓ are lower in Alzheimer's patients (varies by region/study). - Cholinergic system (clinical target): reduction in ACh↓ production; ChAT↓ activity reduced (synthesizes ACh). - Four key enzymes frequently targeted in AD symptom/adjunct strategies: AChE, BChE, MAOA, MAOB (objective inhibit). - Neurotrophic tone (reported): BDNF↓ in key regions. - Stress can decrease expression of brain-derived neurotrophic factor (BDNF). - Kinase/protease stress (reported): CDK5↑ hyperactivation; calpain↑ overactivated by increased intracellular Ca²⁺ → p-tau and aggregation. - Aβ-linked synaptic regulator (reported): STEP↑ upregulated largely due to Aβ oligomer accumulation. - α-secretase axis (reported): ADAM10↓ downregulated in AD brains. - Metabolic cofactors (reported): ALC↓ (ALCAR); Homocarnosine↓ (CSF declines with age); possible low Taurine↓ (age-related + dementia reports). - Ion/glutamate handling (reported): impaired glutamate clearance + depressed Na+/K+ ATPase → cellular ion imbalance risk. - Aging reduces NAD⁺↓ (in AD depletion may be more severe). - Mitochondrial capacity axis (reported): PGC-1↓ decreased in Alzheimer’s brains. - Innate immune DNA-sensing axis (animal): cGAS–STING↑ elevation observed in AD mice and normalized by NR treatment. - Vascular/structure (reported): a profound change in BBB permeability; progressive brain shrinkage (atrophy). - Glycation axis (reported): AGEs↑ and RAGE↑ expression. HOMOCYSTEINE / B-VITAMIN AXIS: - Raised plasma total homocysteine (tHcy)↑ associated with cognitive impairment, AD, or vascular dementia (epidemiology). - Homocysteine can build up if vitamin B6, B12, or folate levels are low. - Homocysteine and B-vitamin in Cognitive Impairment (VITACOG) study. - Vit B6 might be an important B vitamin (often discussed along with B12 and folate). - Thiamine↓ deficiency produces a cholinergic deficit (well-aligned with AD features). - Decreased thiamine (B1) in AD may exacerbate Aβ deposition, tau hyperphosphorylation, and oxidative stress (reported). MICRONUTRIENTS / CAROTENOIDS (reported; compartment-dependent): - vitamin A↓ and β-carotene↓ lower in some AD cohorts; excess retinol may contribute to osteoporosis risk. - Diminished circulating vitamin E↓ reported in AD. - Vitamin B5↓ in multiple brain regions (reported). - Trace elements: patients with AD reported lower serum Se, Cu, and Zn↓ (serum findings vary by study). - Brain metals: some studies report higher brain copper↑ and iron↑ in specific regions/structures; compartment and region matter. Rosmarinic acid reported to reduce copper-induced neurotoxicity in vitro/in vivo and may interfere with amyloid–copper interactions (preclinical). - SAMe↓ concentrations in CSF reported in AD. - MPOD often reduced in AD patients. - AD brains reported lower levels of lutein↓, zeaxanthin↓, anhydrolutein↓, (VitA)retinol↓, lycopene↓, alpha-tocopherol↓. RISK CONTEXT: - Apolipoprotein E4 (ApoE4) genotype is the strongest known genetic risk factor for late-onset AD. - One copy of ApoE4: ~3–4× increased risk (range varies by cohort). - Two copies: ~8–12× increased risk (range varies). - VitK lower in circulating blood of APOE4 carriers (reported). - Type 2 diabetes, traumatic brain injury, stroke, diet, and above all, aging is the number ONE risk factor. Treatments / Strategy Targets (high-level): - Early intervention tends to have a greater positive effect than interventions during middle or late stages. - BOLD fMRI imaging can be used to observe brain activity via blood oxygen/flow changes. - Reduce ROS and inflammation in the brain (context-dependent; avoid over-suppressing adaptive signaling). - Inhibiting acetylcholinesterase (AChE) (which breaks down ACh), e.g., donepezil, rivastigmine. - Natural AChE inhibitors include: Berberine, Luteolin, Crocetin(saffron), Querctin, TQ - Natural AChE inhibitors in database (check BBB pass potential). - MAOB inhibitors, APP inhibitors, PGE2 inhibitors, NLRP3 inhibitors, BACE inhibitors - BDNF activators, PSD95 activator - STEP, ADAM10 - Diets with an adequate ratio (5:1) of omega-6:3 (Mediterranean diet). - Vitamins B1, B6, B12, B9 (folic acid) and D, choline, iron and iodine exert neuroprotective effects (general nutrition framing). - Antioxidants (vitamins C, E, A, zinc, selenium, lutein and zeaxanthin). - Fiber may promote gut microbiome diversity influencing brain health. - Supplementing with NAD⁺ precursors (NR or NMN) improves cognition and reduces amyloid/tau pathologies in AD mice (animal evidence). - "It is advisable to consume diets with an adequate ratio (5:1) of omega-6:3 fatty acids (Mediterranean diet) ... antioxidants ... role in oxidative stress ... cognition."
