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: Proapototic
cyclin-dependent kinase inhibitor p21 (also known as p21 WAF1/Cip1) promotes cell cycle arrest in response to many stimuli.
P21 is a cyclin-dependent kinase inhibitor that plays a crucial role in regulating the cell cycle. It is encoded by the CDKN1A gene and is a key player in the cellular response to stress, including DNA damage.
P21 is often considered a tumor suppressor because its expression is upregulated in response to p53 activation, a well-known tumor suppressor protein. When DNA damage occurs, p53 can activate the transcription of the CDKN1A gene, leading to increased levels of P21, which helps prevent the proliferation of damaged cells.
In many cancers, the p53 pathway is disrupted, leading to decreased levels of P21. p21 is a apoptotic marker protein.
