Features:
Flavonoid glycoside. Responsible for the bitterness of grapefruit.
Naringin is a flavonoid glycoside predominantly found in citrus fruits such as grapefruit and oranges. It is known for its antioxidant, anti-inflammatory, and potential anticancer properties.
It is hydrolyzed in vivo to naringenin, which exhibits antioxidant and anti-inflammatory activities and modulates signaling pathways (e.g., Nrf2 and NF-κB). In preclinical cancer models, naringin/naringenin is associated with cell-cycle arrest, apoptosis, and reduced invasion/metastasis, often linked to upstream modulation of survival pathways (PI3K/AKT) and stress MAPKs. Oral systemic exposure is limited due to metabolism and conjugation.
-Antioxidant Activity
-Induction of Apoptosis
-Cell Cycle Arrest (often G1 or G2/M)
-Anti-inflammatory Effects

-**a natural bioenhancer(effects vary) and reported to enhance the bioavailability of drugs by inhibiting cytochrome P450 (CYP3A4 especially grape fruit juice) and P-glycoprotein (P-gp). Naringin/naringenin can inhibit CYP3A4 and P-glycoprotein, contributing to grapefruit–drug interactions and potentially increasing exposure of certain medications.
-Usually paired with other bioflavonoids such as quercetin, hesperidin and rutin.

-Mainly obtained from grapefruit
-Including enhanced solubility, improved bioavailability and targeted delivery.
-Antioxidant
-Inhibition of CYP19(weak/modest). Naringin suppresses the PI3K/AKT signalling pathway
-Wnt/β-catenin, PI3K/Akt, NF-ĸB, and TGF-β pathways
-Up-regulation of adenosine monophosphate-activated protein kinase (AMPK), and inhibition of gluconeogenesis
-Antioxidant effects, by modulating reactive oxygen species (ROS) levels and increasing superoxide dismutase (SOD)
-Naringenin can reduce carcinogenesis through pleiotropic processes such as antioxidative, apoptotic-inducing ROS generation, and cell cycle arrest
-Revealed new mechanisms underlying the hypolipidemic effects of naringin and naringenin, including regulation of lipid digestion, reverse cholesterol transport, and low-density lipoprotein receptor expression
-Low bioavailability (approximately 8.8%) when administered orally. Bioavailability: citrus flavonoid glycosides are hydrolyzed in the gut; systemic plasma levels are often much lower than in vitro MICs.

Rank Pathway / Axis Cancer Cells Normal Cells TSF Primary Effect Notes / Interpretation
1 Nrf2/ARE antioxidant response Stress adaptation modulation (context-dependent) Nrf2 ↑; antioxidant enzymes ↑ R, G Endogenous antioxidant upshift Naringin and its aglycone naringenin are widely reported to activate Nrf2, elevate HO-1 and other antioxidant defenses, and reduce oxidative injury in many models.
2 NF-κB inflammatory signaling NF-κB ↓; pro-inflammatory cytokines ↓ (reported) Inflammation tone ↓ R, G Anti-inflammatory signaling Consistent evidence shows naringin/naringenin reduces pro-inflammatory signaling and cytokine expression in tumor and non-tumor contexts.
3 PI3K/AKT/mTOR survival axis PI3K/AKT ↓ (reported; model-dependent) ↔ R, G Growth/survival modulation Modulation of survival pathways is observed in various cancer‐cell studies, but effects vary by cell type and context.
4 Cell cycle control (Cyclins/CDKs) Cell-cycle arrest ↑ (G1/S or G2/M; reported) ↔ G Cytostasis Often reported as reduced proliferation and cell cycle arrest following upstream signaling changes.
5 Intrinsic apoptosis (mitochondrial/caspase linked) Apoptosis ↑; caspase activation ↑ (reported) ↔ G Execution of cell death Observed in many in vitro models, usually downstream of signaling modulation and stress pathways.
6 MAPK re-wiring (ERK / JNK / p38) MAPK modulation (context-dependent) ↔ P, R, G Stress/mitogenic signaling adjustment MAPK effects vary by assay and cell type; avoid fixed up/down arrows without a specific citation.
7 Invasion / metastasis programs (MMPs/EMT) MMPs ↓; migration/invasion ↓ (reported) ↔ G Anti-invasive phenotype Downstream phenotype changes reported in some models; linked to NF-κB/MAPK modulation.
8 Angiogenesis signaling (VEGF & related) Angiogenic outputs ↓ (reported) ↔ G Anti-angiogenic support Later phenotype outcomes; direction is often model-dependent.
9 Reactive oxygen species modulation Redox buffering; ROS direction variable ↔ P, R, G Redox modulation (context-dependent) Naringin is classically antioxidant; ROS changes in cancer models vary and are not reliably pro-oxidant under typical conditions.
10 Bioavailability / metabolism constraint Systemic exposure limited; rapid metabolism/conjugation — — Translation constraint Naringin’s glycoside form is hydrolyzed to naringenin; phase II conjugates circulate. Native systemic levels are often low compared with in vitro effective concentrations.

Time-Scale Flag (TSF): P / R / G

  • P: 0–30 min (rapid biochemical/signaling interactions)
  • R: 30 min–3 hr (acute signaling and transcription modulation)
  • G: >3 hr (gene-regulatory adaptation and phenotype outcomes)
uPA, Urokinase plasminogen activator: Click to Expand ⟱
Source:
Type:
uPA (urokinase plasminogen activator) is a serine protease that plays a crucial role in the conversion of plasminogen to plasmin, an enzyme responsible for degrading various components of the extracellular matrix (ECM). This activity is central to processes such as tissue remodeling, cell migration, and angiogenesis. In the context of cancer, uPA facilitates tumor invasion and metastasis by promoting ECM degradation, while its interaction with its receptor (uPAR) and inhibitors (such as PAI-1) forms a regulatory axis that is frequently dysregulated in malignancies.

Patients with higher pretreatment serum uPA (≥1 ng/ml) had significantly shorter OS.

Elevated uPA expression has been observed in a broad range of cancers, including breast, colorectal, lung, and prostate cancers. These high levels are often indicative of increased proteolytic activity within the tumor microenvironment.
Tumors with aggressive behavior often exhibit upregulation of uPA, along with its receptor uPAR. This upregulation enhances plasmin generation and leads to an environment conducive to invasion and metastasis.

Elevated uPA levels in tumor tissues have been strongly associated with poor clinical outcomes. High uPA expression is correlated with increased risk of metastasis, higher likelihood of recurrence, and reduced overall survival in several cancer types.
