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


ZO-1, Zonula occludens-1: Click to Expand ⟱
Source:
Type:
ZO-1 (Zonula occludens-1) is a protein that plays a crucial role in the formation and maintenance of tight junctions in epithelial cells. Tight junctions are essential for maintaining the integrity of epithelial barriers and regulating the passage of ions and molecules across the cell membrane.

In the context of cancer, ZO-1 has been implicated in several ways:

1.Loss of ZO-1 expression: Reduced or lost expression observed in various types of cancer.
2.Disruption of tight junctions: Cancer cells often exhibit disrupted tight junctions, which can lead to increased permeability and the loss of epithelial barrier function. ZO-1 is a key component of tight junctions, and its disruption can contribute to the development and progression of cancer.
3.Epithelial-to-mesenchymal transition (EMT): ZO-1 has been shown to play a role in regulating EMT, a process by which epithelial cells acquire a mesenchymal phenotype. EMT is a key event in the development of cancer metastasis, and ZO-1's role in regulating this process is an area of active research.
4.Tumor suppressor function: ZO-1 has been proposed to have tumor suppressor functions, and its loss or downregulation can contribute to the development of cancer. ZO-1's tumor suppressor functions may be related to its ability to regulate cell growth, apoptosis, and cell migration.

ZO-1 generally acts as a tumor suppressor by maintaining epithelial integrity. In many cancers, downregulation or mislocalization of ZO-1 is observed and is associated with a poorer prognosis due to the facilitation of EMT and metastasis.
