GSE, Grapeseed extract: Click to Expand ⟱
Features:
Grapeseed extract (GSE) is rich in oligomeric proanthocyanidins (OPCs), catechins, and other polyphenols derived from Vitis vinifera seeds. In cancer research, GSE is most consistently associated with antioxidant and anti-inflammatory signaling modulation, suppression of PI3K/AKT and MAPK pathways, induction of cell-cycle arrest, and promotion of apoptosis in preclinical models. GSE has also been reported to inhibit angiogenesis (via VEGF suppression), reduce metastasis-related markers (e.g., MMPs), and modulate redox balance in tumor cells. Effects are concentration-dependent and vary by tumor type. While GSE is frequently described as antioxidant in normal tissues, pro-oxidant effects have been reported in tumor contexts at higher concentrations. Human oncology data remain limited; most findings derive from in vitro and animal studies.
Made from seeds of grapes and contains antioxidants Vitamin E, linolenic acid and OPCs.


Cancer Pathway Table: Grapeseed Extract

Rank Pathway / Axis Cancer / Tumor Context Normal Tissue Context TSF Primary Effect Notes / Interpretation
1 NF-κB inflammatory / survival signaling NF-κB ↓; COX-2 ↓; cytokines ↓ (reported) Inflammatory tone ↓ R, G Anti-inflammatory / anti-survival Consistent suppression of inflammatory signaling in multiple tumor models.
2 PI3K → AKT → mTOR axis PI3K/AKT ↓; proliferation ↓ (model-dependent) ↔ R, G Growth signaling suppression Frequently reported mechanism contributing to reduced tumor growth.
3 Intrinsic apoptosis (mitochondrial pathway) Bax ↑; Bcl-2 ↓; caspases ↑ (reported) Minimal apoptosis at lower exposure G Apoptotic induction Apoptosis induction associated with mitochondrial depolarization and cytochrome c release.
4 Cell-cycle arrest (G1 / G2-M) Cell-cycle arrest ↑ (reported) ↔ G Cytostasis Often linked to decreased Cyclin D1/CDK expression.
5 ROS modulation (biphasic) ROS ↑ in some tumor contexts; apoptosis ↑ ROS ↓; antioxidant protection P, R Redox modulation Polyphenol-rich extracts may act antioxidant in normal cells and pro-oxidant in tumor cells at higher doses.
6 Nrf2 / ARE pathway Context-dependent modulation Nrf2 ↑; antioxidant enzyme expression ↑ R, G Redox regulation Common polyphenol signature; may protect normal tissue during oxidative stress.
7 MAPK signaling (ERK / JNK / p38) Stress-MAPK modulation (context-dependent) ↔ P, R, G Signal reprogramming JNK/p38 activation linked to apoptosis; ERK modulation varies.
8 Angiogenesis (VEGF signaling) VEGF ↓; angiogenesis ↓ (reported) ↔ G Anti-angiogenic Anti-angiogenic activity observed in several preclinical systems.
9 Metastasis / invasion (MMPs) MMP2/MMP9 ↓; migration ↓ (reported) ↔ G Anti-invasive phenotype Likely downstream of NF-κB and MAPK suppression.
10 Bioavailability constraint Systemic exposure limited; metabolite-driven effects Generally well tolerated — Translation constraint OPCs have limited oral bioavailability; many in vitro concentrations exceed typical plasma levels.

TSF: P = rapid redox effects; R = signaling pathway modulation; G = apoptosis, angiogenesis, and phenotype-level changes.

Type:
Also known as Cadherin1 (CDH1)
E-cadherin, is a type of cell adhesion molecule that plays a crucial role in maintaining tissue structure and cell-cell interactions. In the context of cancer, E-cadherin has been found to be a tumor suppressor gene.

E-cadherin is a transmembrane protein that mediates cell-cell adhesion through its extracellular domain, which interacts with other E-cadherin molecules on adjacent cells. This interaction helps to maintain tissue integrity and prevent cancer cells from invading surrounding tissues.

In many types of cancer, including breast, colon, and prostate cancer, E-cadherin expression is often reduced or lost.
cell adhesion molecules spanning four families of 1) Integrins (α2β1, α5/β1, αL/β2); 2) Cadherins (E-cad, P-cad, N-cad); 3) Ig-CAMs (VCAM, NCAM, ICAM, Nectins, Necl); and 4) Selectins (E-selectin, P-selectin, L-selectin).
