Ginseng / NRF2 Cancer Research Results

Gins, Ginseng: Click to Expand ⟱
Features:

Ginseng = adaptogenic herbal root from the genus Panax; main species: Asian ginseng (Panax ginseng) and American ginseng (Panax quinquefolius). Active constituents: ginsenosides (Rb1, Rg1, Rg3, Rh2), polysaccharides, and other saponins.
Primary mechanisms (conceptual rank):
1) Multi-pathway signaling modulation (PI3K/Akt, MAPK, NF-κB; isoform-dependent).
2) Redox regulation (bidirectional ROS modulation; NRF2 interaction).
3) Anti-inflammatory and immunomodulatory effects.
4) Anti-proliferative and pro-apoptotic effects in cancer (notably Rg3, Rh2; dose-dependent).
5) Neurotrophic and cholinergic modulation (BDNF, ACh support).
PK / bioavailability: ginsenosides have variable oral absorption; gut microbiota convert to active metabolites (e.g., Compound K); plasma levels generally lower than many in-vitro doses.
In-vitro vs systemic exposure: many cancer studies use ≥10–100 µM; achievable plasma concentrations after oral dosing are typically lower and metabolite-driven.
Clinical evidence status: supportive oncology (fatigue reduction) supported by RCTs; direct anti-cancer efficacy largely preclinical; cognitive and fatigue benefits better substantiated.

Ginseng (Panax ginseng) – This herb has been studied for its ability to enhance the immune system.
-Antioxidant Properties: Ginseng contains ginsenosides, which have antioxidant properties.
-Immune System Support
-Inhibition of Tumor Growth
-Chemopreventive Effects
-Synergistic Effects with Cancer Treatments: ginseng may enhance the effectiveness of certain cancer treatments, such as chemotherapy, and may help reduce side effect
Dose: Standardized Extract:
Dosage: extract containing 4-7% ginsenosides 200-400mg/d
Dried Root:1-2g/d
Tea: 1-2g dried root, 1-3x/d

NRF2, nuclear factor erythroid 2-related factor 2: Click to Expand ⟱
Source: TCGA
Type: Antiapoptotic
Nrf2 is responsible for regulating an extensive panel of antioxidant enzymes involved in the detoxification and elimination of oxidative stress. Thought of as "Master Regulator" of antioxidant response.
-One way to estimate Nrf2 induction is through the expression of NQO1.
NQO1, the most potent inducer:
SFN 0.2 μM,
quercetin (2.5 μM),
curcumin (2.7 μM),
Silymarin (3.6 μM),
tamoxifen (5.9 μM),
genistein (6.2 μM ),
beta-carotene (7.2μM),
lutein (17 μM),
resveratrol (21 μM),
indol-3-carbinol (50 μM),
chlorophyll (250 μM),
alpha-cryptoxanthin (1.8 mM),
and zeaxanthin (2.2 mM)

1. Raising Nrf2 enhances the cell's antioxidant defenses and ↓ROS. This strategy is used to decrease chemo-radio side effects.
2. Downregulating Nrf2 lowers antioxidant defenses and ↑ROS. In cancer cells this leads to DNA damage, and cell death.
3. However there are some cases where increasing Nrf2 paradoxically causes an increase in ROS (cancer cells). Such as cases of Mitochondial overload, signal crosstalk, reductive stress

-In some cases, Nrf2 is overexpressed in cancer cells, which can lead to the activation of genes involved in cell proliferation, angiogenesis, and metastasis. This can contribute to the development of resistance to chemotherapy and targeted therapies.
-Increased Nrf2 expression: Lung, Breast, Colorectal, Prostrate.
Decreased Nrf2 expression: Skine, Liver, Pancreatic.
-Nrf2 is a cytoprotective transcription factor which demonstrated both a negative effect as well as a positive effect on cancer
- "promotes Nrf2 translocation from the cytoplasm to the nucleus," means facilitates the movement of Nrf2 into the nucleus, thereby enhancing the cell's antioxidant and cytoprotective responses. -Major regulator of Nrf2 activity in cells is the cytosolic inhibitor Keap1.

Nrf2 Inhibitors and Activators
Nrf2 Inhibitors: Brusatol, Luteolin, Trigonelline, VitC, Retinoic acid, Chrysin
Nrf2 Activators: SFN, OPZ EGCG, Resveratrol, DATS, CUR, CDDO, Api
- potent Nrf2 inducers from plants include sulforaphane, curcumin, EGCG, resveratrol, caffeic acid phenethyl ester, wasabi, cafestol and kahweol (coffee), cinnamon, ginger, garlic, lycopene, rosemany

Nrf2 plays dual roles in that it can protect normal tissues against oxidative damage and can act as an oncogenic protein in tumor tissue.
– In healthy tissues, NRF2 activation helps protect cells from oxidative damage and maintains cellular homeostasis.
– In many cancers, constitutive activation of NRF2 (often through mutations in NRF2 itself or loss-of-function mutations in KEAP1) leads to an enhanced antioxidant capacity.
– This upregulation can promote tumor cell survival by enabling cancer cells to thrive under oxidative stress, resist chemotherapeutic agents, and sustain metabolic reprogramming.
– Elevated NRF2 levels have been implicated in promoting tumor growth, metastasis, and resistance to therapy in various malignancies.
– High or sustained NRF2 activity is frequently associated with aggressive tumor phenotypes, poorer prognosis, and decreased overall survival in several cancer types.
– While its activation is essential for protecting normal cells from oxidative stress, aberrant or sustained NRF2 activation in tumor cells can lead to enhanced survival, therapeutic resistance, and tumor progression.

NRF2 inhibitors: (to decrease antioxidant defenses and increase cell death from ROS).
-Brusatol: most cited natural inhibitors of Nrf2.
-Luteolin: luteolin can reduce Nrf2 activity in specific cancer models and may enhance cell sensitivity to chemotherapy. However, luteolin is also known as an antioxidant, and its influence on Nrf2 can sometimes be context dependent.
-Apigenin: certain studies to down‑regulate Nrf2 in cancer cells: Dose and context dependent .
-Oridonin:
-Wogonin: although its effects might be cell‑ and dose‑specific.
- Withaferin A
