- 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


UPR, Unfolded Protein Response: Click to Expand ⟱
Source:
Type:
Cellular stress response related to the endoplasmic reticulum (ER) stress, which involves protein folding, quality control, and signaling pathways. The unfolded protein response (UPR) is the cells' way of maintaining the balance of protein folding in the endoplasmic reticulum. (UPR) is triggered by the presence of misfolded proteins in the endoplasmic reticulum.
The UPR is a cellular stress response activated by the accumulation of unfolded or misfolded proteins in the endoplasmic reticulum (ER).
- It is primarily mediated by three ER-resident sensors: IRE1α, PERK, and ATF6.

Cancer cells often experience high levels of protein synthesis, hypoxia, nutrient deprivation, and oxidative stress, all of which can activate the UPR.
– Numerous studies have reported that key UPR components (e.g., GRP78/BiP, IRE1α, PERK, CHOP) are overexpressed in various malignancies such as breast, pancreatic, lung, and prostate cancers.

Unfolded Protein Response is typically upregulated in cancers and is associated with poorer prognosis due to its role in promoting cell survival, adaptation to stress, and therapeutic resistance. Although the UPR harbors the potential for tumor-suppressive (apoptotic) effects under severe stress conditions, its predominant activation in tumors supports an adaptive, protumorigenic state that facilitates cancer progression. Targeting UPR components and modulating this balance remain promising therapeutic strategies.
