- 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


P450, cytochrome P450 (CYP) family: Click to Expand ⟱
Source:
Type:
The cytochrome P450 (CYP) family includes many isoenzymes that play key roles in metabolizing endogenous substances (like hormones) and xenobiotics (including drugs and toxins). Changes in the expression of these enzymes in various cancers can affect carcinogen activation, drug metabolism, and overall tumor biology, influencing both cancer risk and prognosis.

CYP1B1
– Frequently overexpressed in several cancers including breast, ovarian, prostate, and colorectal cancers.
– Its expression is often low in normal tissues, making it a potential target for selective cancer therapies.

2. CYP3A4 and CYP3A5
These enzymes are highly expressed in the liver, but their expression is also observed in extrahepatic tissues.
– In cancer, CYP3A enzymes can be variably expressed; for instance, CYP3A4 may be upregulated in some liver cancers but downregulated in others.

3. CYP2E1
– CYP2E1 is expressed in the liver and extrahepatic tissues.
– Elevated CYP2E1 activity can lead to increased production of reactive oxygen species (ROS), contributing to DNA damage and cancer progression.

4. CYP19A1 (Aromatase)
– Aromatase converts androgens to estrogens and is expressed in adipose tissue as well as in certain tumors such as breast cancer.
– Its local expression in breast tumors can increase estrogen levels, promoting hormone-dependent tumor growth.

5. CYP2C Family (e.g., CYP2C8, CYP2C9, CYP2C19)
– These enzymes are involved in metabolizing various drugs and are expressed in the liver and intestines.
– Their expression levels can be altered in different tumor types, potentially affecting drug metabolism.

CYP450 enzymes are a large family with diverse roles in cancer biology.
• Their expression in cancers (e.g., CYP1B1, CYP3A4/5, CYP2E1, CYP19A1) has been linked to both the development and progression of tumors, as well as influencing responses to therapy.
