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


ATF4, Activating Transcription Factor 4: Click to Expand ⟱
Source:
Type: protein
ATF4 (Activating Transcription Factor 4) is a protein that plays a crucial role in various cellular processes, including stress response, cell growth, and differentiation.
ATF4 is overexpressed in several types of cancer, including breast, lung, colon, and pancreatic cancer. The overexpression of ATF4 can contribute to cancer cell growth, survival, and resistance to chemotherapy.
ATF4 promotes cancer cell growth by regulating the expression of genes involved in cell proliferation, angiogenesis, and metastasis. It also inhibits apoptosis (programmed cell death) by regulating the expression of anti-apoptotic genes.
