Primary Effect |
Notes / Interpretation |
| 1 |
NF-κB inflammatory transcription |
NF-κB ↓; COX-2 ↓; pro-inflammatory cytokines ↓ (reported) |
Inflammation tone ↓ |
R, G |
Anti-inflammatory / anti-survival transcription |
One of the most consistent ginger signatures; reduction of inflammatory tumor-support signaling. |
| 2 |
PI3K → AKT (± mTOR) survival axis |
PI3K/AKT ↓ (reported; model-dependent) |
↔ |
R, G |
Growth/survival modulation |
Often described in conjunction with apoptosis and proliferation reduction. |
| 3 |
ROS / redox modulation (biphasic) |
ROS ↑ (at higher doses); apoptosis ↑ |
ROS ↓; antioxidant activity |
P, R |
Redox destabilization (tumor) / buffering (normal) |
Gingerols and shogaols may act antioxidant in normal tissue but pro-oxidant in tumor systems under higher concentrations. |
| 4 |
Intrinsic apoptosis (mitochondrial pathway) |
ΔΨm ↓; Bax ↑; caspase-3 ↑ (reported) |
↔ (less activation) |
G |
Apoptosis execution |
Often downstream of ROS and survival-pathway suppression. |
| 5 |
Cell-cycle arrest (G1 or G2/M) |
Cell-cycle arrest ↑ (reported) |
↔ |
G |
Cytostasis |
Associated with modulation of Cyclins/CDKs; phase varies by tumor type. |
| 6 |
MAPK pathways (ERK / JNK / p38) |
Stress-MAPK modulation (context-dependent) |
↔ |
P, R, G |
Signal reprogramming |
JNK/p38 activation often linked to stress-induced apoptosis; ERK direction varies. |
| 7 |
STAT3 signaling |
STAT3 ↓ (reported) |
↔ |
R, G |
Transcriptional survival suppression |
Observed in certain tumor models; contributes to reduced proliferation and invasion. |
| 8 |
Angiogenesis signaling (VEGF) |
VEGF ↓ (reported) |
↔ |
G |
Anti-angiogenic support |
Typically a downstream effect of inflammatory and survival pathway suppression. |
| 9 |
Invasion / metastasis (MMPs / EMT) |
MMP-2/MMP-9 ↓; migration ↓ (reported) |
↔ |
G |
Anti-invasive phenotype |
Frequently linked to NF-κB and STAT3 suppression. |
| 10 |
Bioavailability constraint |
Systemic free gingerol levels low; rapid conjugation |

Translation constraint |
In-vitro cytotoxic concentrations often exceed achievable plasma levels after dietary intake. |
