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

Type:

Cyclin-dependent kinase 4 (CDK4) is a key regulator of the cell cycle, particularly in the transition from the G1 phase to the S phase. Its expression and activity are often altered in various cancers, contributing to tumorigenesis.
CDK4 is frequently overexpressed in various cancers, and its expression levels can serve as a prognostic marker.
