- Selectivity: Cancer Cells vs 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

Aβ42 - Amyloid Beta 1-42

Type: Amyloid peptide / Alzheimer's disease pathological protein / biomarker

Function: Aβ42 is a 42-amino-acid amyloid-beta peptide generated from amyloid precursor protein (APP) through sequential cleavage by β-secretase and γ-secretase. Compared with shorter Aβ species such as Aβ40, Aβ42 is more hydrophobic and aggregation-prone and readily forms oligomers, fibrils, and amyloid plaques.

Alzheimer's Disease: ↑ in aggregated brain deposits / ↓ in soluble CSF. Aβ42 is a major component of cerebral amyloid plaques and its aggregation is a defining feature of Alzheimer's disease pathology. Increased accumulation of oligomeric and fibrillar Aβ42 is associated with synaptic dysfunction, neuroinflammation, oxidative stress, and neuronal injury. In contrast, soluble CSF Aβ42 typically decreases as cerebral amyloid deposition increases, and a reduced CSF or plasma Aβ42/Aβ40 ratio is used as a biomarker of amyloid pathology.
