Features:
Ginkgo biloba from an ancient tree.
Ginkgo biloba leaf extracts (commonly standardized as EGb 761, ~24% flavonol glycosides and ~6% terpene lactones) are best known for antioxidant, anti-inflammatory, platelet-activating factor (PAF) antagonism, and neurovascular effects. In preclinical cancer models, Ginkgo constituents have been associated with modulation of NF-κB, Nrf2, MAPK, and PI3K/AKT pathways, along with effects on cell cycle, apoptosis, and angiogenesis. Clinical oncology evidence is limited and heterogeneous. Important safety considerations include antiplatelet effects (bleeding risk) and CYP/P-gp interactions (product- and dose-dependent).

-Ginkgo can inhibit platelet aggregation

-Scavenges free radicals; reduces oxidative stress in neuronal cells -Suppresses pro-inflammatory cytokines (e.g., TNF-α, IL-1β).
-Enhances microcirculation and oxygen delivery to brain tissues.
-Reduces Aβ plaque formation and associated neurotoxicity.
-May improve memory, attention, and processing speed in early-stage AD.


Rank Pathway / Axis Cancer / Tumor Context Normal Tissue Context TSF Primary Effect Notes / Interpretation
1 Antioxidant systems (Nrf2/ARE; SOD, GSH) Stress adaptation modulation (context-dependent) Nrf2 ↑; antioxidant enzymes ↑; oxidative injury ↓ R, G Redox buffering Flavonol glycosides commonly activate antioxidant defenses; direction in tumors is model-dependent.
2 NF-κB inflammatory transcription NF-κB ↓; cytokines/COX-2 ↓ (reported) Inflammation tone ↓ R, G Anti-inflammatory signaling Preclinical studies report NF-κB modulation; strength varies by constituent and dose.
3 PAF receptor antagonism (ginkgolides) Pro-tumor inflammatory signaling ↓ (context) Platelet activation ↓; microcirculation effects P, R Lipid mediator antagonism Ginkgolides are PAF antagonists; clinically relevant for antiplatelet/vascular effects.
4 PI3K → AKT (± mTOR) survival axis PI3K/AKT modulation (reported; model-dependent) ↔ R, G Growth/survival modulation Observed in some tumor models; best described as reported/context-dependent.
5 MAPK re-wiring (ERK / JNK / p38) MAPK modulation (context-dependent) ↔ P, R, G Stress/mitogenic signaling adjustment Directions vary by extract composition and cell type.
6 Cell-cycle control (Cyclins/CDKs) Cell-cycle arrest ↑ (reported) ↔ G Cytostasis Reported in vitro; typically downstream of signaling changes.
7 Intrinsic apoptosis (mitochondrial/caspase linked) Apoptosis ↑ (reported) ↔ G Cell death execution Seen in selected cancer cell lines; not a universal cytotoxin signature.
8 Angiogenesis signaling (VEGF & related) Angiogenic outputs ↓ (reported) ↔ G Anti-angiogenic phenotype Phenotype-level outcomes in some models; strength varies.
9 Drug metabolism / transport (CYPs, P-gp) Potential interaction with chemo agents (context) CYP/P-gp modulation (product- and dose-dependent) R, G Interaction constraint Reports of CYP (e.g., CYP2C19/3A4) and P-gp modulation are mixed; interaction risk depends on extract and dose.
10 Safety constraint (antiplatelet / bleeding risk) — Platelet aggregation ↓; bleeding risk ↑ (context) — Clinical risk management PAF antagonism and antiplatelet effects warrant caution with anticoagulants/antiplatelets and perioperatively.

Rank Pathway / Axis AD / Neural Context TSF Primary Effect Notes / Interpretation
1 Oxidative stress reduction (Nrf2/ARE; SOD, GSH) Oxidative injury ↓; lipid peroxidation ↓ R, G Neuroprotection via redox buffering Flavonol glycosides enhance endogenous antioxidant defenses and reduce oxidative stress, a core driver in AD pathology.
2 Mitochondrial protection ATP production stabilization; mitochondrial membrane integrity ↑ P, R Energy support EGb 761 has been reported to protect mitochondrial function and reduce ROS generation in neuronal models.
3 Neuroinflammation (NF-κB; microglial activation) Microglial activation ↓; pro-inflammatory cytokines ↓ R, G Anti-inflammatory neuroprotection Reduction of neuroinflammatory signaling may contribute to slowed neurodegenerative processes.
4 Platelet-activating factor (PAF) antagonism Improved cerebral microcirculation; reduced inflammatory mediator activity P Vascular support Ginkgolides act as PAF antagonists; improved cerebral blood flow may support cognition in vascular/mixed dementia.
5 β-amyloid aggregation modulation Aβ aggregation ↓ (reported in vitro) G Protein aggregation modulation Preclinical studies suggest interference with Aβ toxicity and aggregation; clinical relevance remains uncertain.
6 Synaptic plasticity / neurotransmission Cholinergic tone modulation (reported); synaptic resilience ↑ G Cognitive support Some evidence suggests improved synaptic function and neurotransmission in aging models.
7 Apoptosis suppression (neuronal survival) Pro-apoptotic signaling ↓ (reported) G Neuronal preservation Reduction of caspase activation and mitochondrial apoptotic signaling has been reported in neuronal injury models.
8 Clinical cognitive outcomes Modest cognitive benefit in mild-to-moderate dementia (mixed results) — Symptom-level effect Some randomized trials suggest small improvements in cognition or activities of daily living; others show limited effect. Benefit appears modest.
9 Safety constraint (antiplatelet effect) Bleeding risk ↑ in susceptible patients — Clinical risk management PAF antagonism and platelet aggregation inhibition require caution with anticoagulants and perioperative settings.

Type:
Once the cancer has begun, NO seems to play a protumoral role rather than antitumoral one as the concentration required to cause tumor cell cytotoxicity cannot be achieved by cancer cells.
The mechanistic roles of nitric oxide (NO) during cancer progression have been important considerations since its discovery as an endogenously generated free radical. Nonetheless, the impacts of this signaling molecule can be seemingly contradictory, being both pro-and antitumorigenic, which complicates the development of cancer treatments based on the modulation of NO fluxes in tumors. At a fundamental level, low levels of NO drive oncogenic pathways, immunosuppression, metastasis, and angiogenesis, while higher levels lead to apoptosis and reduced hypoxia and also sensitize tumors to conventional therapies. However, clinical outcome depends on the type and stage of the tumor as well as the tumor microenvironment.
Nitric oxide is generated by three main nitric oxide synthase isoforms: neuronal (nNOS), endothelial (eNOS), and inducible (iNOS).

– In many cancers, especially under inflammatory conditions, iNOS expression is upregulated. In contrast, eNOS levels may also be altered in cancers such as breast or prostate cancer.

• Expression Patterns in Tumors:
– Elevated iNOS expression is commonly observed in various tumor types (e.g., colon, breast, lung, and melanoma) and is often associated with an inflammatory microenvironment.

– Changes in eNOS and nNOS expression have also been reported and may contribute to angiogenesis and tumor blood flow regulation.
