- 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


IGF-1, insulin-like growth factor-1: Click to Expand ⟱
Source:
Type:
Higher blood levels of IGF-1, a growth factor, are linked to increased risk of several types of cancer, including thyroid, melanoma and myeloma. IGF-1 is what some call "a growth-promoter" because it has been shown to promote the growth of cancer cells.
The IGF-1 signaling pathway promotes cancer progression; its downregulation is associated with lowered risk.

2906- LT,    Luteolin, a flavonoid with potentials for cancer prevention and therapy
- Review, Var, NA
*Inflam↓, anti-inflammation, anti-allergy and anticancer, luteolin functions as either an antioxidant or a pro-oxidant biochemically
AntiCan↑,
antiOx⇅, With low Fe ion concentrations (< 50 μM), luteolin behaves as an antioxidant while high Fe concentrations (>100 μM) induce luteolin's pro-oxidative effect
Apoptosis↑, induction of apoptosis, and inhibition of cell proliferation, metastasis and angiogenesis.
TumCP↓,
TumMeta↓,
angioG↓,
PI3K↓, , luteolin sensitizes cancer cells to therapeutic-induced cytotoxicity through suppressing cell survival pathways such as phosphatidylinositol 3′-kinase (PI3K)/Akt, nuclear factor kappa B (NF-κB), and X-linked inhibitor of apoptosis protein (XIAP)
Akt↓,
NF-kB↓,
XIAP↓, luteolin inhibits PKC activity, which results in a decrease in the protein level of XIAP by ubiquitination and proteasomal degradation of this anti-apoptotic protein
P53↑, stimulating apoptosis pathways including those that induce the tumor suppressor p53
*ROS↓, Direct evidence showing luteolin as a ROS scavenger was obtained in cell-free systems
*GSTA1↑, Third, luteolin may exert its antioxidant effect by protecting or enhancing endogenous antioxidants such as glutathione-S-transferase (GST), glutathione reductase (GR), superoxide dismutase (SOD) and catalase (CAT)
*GSR↑,
*SOD↑,
*Catalase↑,
*other↓, luteolin may chelate transition metal ions responsible for the generation of ROS and therefore inhibit lipooxygenase reaction, or suppress nontransition metal-dependent oxidation
ROS↑, Luteolin has been shown to induce ROS in untransformed and cancer cells
Dose↝, It is believed that flavonoids could behave as antioxidants or pro-oxidants, depending on the concentration and the source of the free radicals
chemoP↑, may act as a chemopreventive agent to protect cells from various forms of oxidant stresses and thus prevent cancer development
NF-kB↓, We found that luteolin-induced oxidative stress causes suppression of the NF-κB pathway while it triggers JNK activation, which potentiates TNF-induced cytotoxicity in lung cancer cells

P450↓, Recently, it was determined that luteolin potently inhibits human cytochrome P450 (CYP) 1 family enzymes such as CYP1A1, CYP1A2, and CYP1B1, thereby suppressing the mutagenic activation of carcinogens
CYP1A1↓,
CYP1A2↓,
TumCCA↑, Luteolin is able to arrest the cell cycle during the G1 phase in human gastric and prostate cancer, and in melanoma cells
