Luteolin a Flavonoid found in celery, parsley, broccoli, onion leaves, carrots, peppers, cabbages, apple skins, and chrysanthemum flowers.
-MDR1 expression, MMP-9, IGF-1 and Epithelial to mesenchymal transition.

-Note half-life 2–3 hours
BioAv low, but could be improved with Res, or blend of castor oil, kolliphor and polyethylene glycol
Pathways:
- induce ROS production in cancer cell but a few reports of reduction. Always seems to reduce ROS in normal cells.

Luteolin — Cancer vs Normal Cell Effects
Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 PI3K → AKT → mTOR axis ↓ AKT / ↓ mTOR signaling ↔ adaptive suppression Driver Loss of survival and growth signaling Luteolin consistently suppresses PI3K/AKT signaling, explaining growth inhibition and apoptosis sensitization
2 NF-κB signaling ↓ NF-κB activation ↓ inflammatory NF-κB tone Driver Suppression of inflammatory survival transcription NF-κB inhibition is a core, repeatedly observed luteolin effect
3 Reactive oxygen species (ROS) ↑ ROS (context- & dose-dependent) ↓ ROS / buffered Conditional Driver Biphasic redox modulation Luteolin can act as a pro-oxidant in cancer cells while remaining antioxidant in normal cells
4 Mitochondrial integrity / intrinsic apoptosis ↓ ΔΨm; ↑ caspase activation ↔ preserved Secondary Execution of intrinsic apoptosis Mitochondrial apoptosis follows signaling and redox stress
5 STAT3 signaling ↓ STAT3 activation ↔ minimal Secondary Loss of proliferative and stemness signaling STAT3 suppression contributes to reduced invasion and CSC traits
6 Cell cycle regulation ↑ G1 or G2/M arrest ↔ spared Phenotypic Cytostatic growth control Cell-cycle arrest reflects upstream pathway inhibition
7 Migration / invasion (EMT, MMP axis) ↓ migration & invasion ↔ Phenotypic Anti-metastatic phenotype Reduced EMT and protease activity limit invasiveness


TrxR1, thioredoxin reductase 1: Click to Expand ⟱
Source:
Type:
TrxR1 or TXNRD1 (Thioredoxin Reductase 1)
Redox Control, Stress Tolerance, and Therapy Resistance
• Many studies have found that an elevated expression of TrxR1 in breast tumors, NSCLC, HCC correlates with increased tumor aggressiveness and a poorer prognosis.
-TrxR1 expression was elevated by >50 fold in FaDu and HeLa cells, and by >20 fold in SCC-1 compared to either MSK-Leuk1 or keratinocytes.

High TXNRD1 expression often associates with:
-Advanced stage
-Therapy resistance
-Reduced survival

TrxR1 Inhibition
-Collapses redox control
-Causes rapid ROS accumulation
-Triggers apoptosis, especially in high-stress tumors
