- Selectivity: Cancer Cells vs Normal Cells
Rank Pathway / Target Axis Direction Primary Effect Notes / Cancer Relevance
1 PKM2-mediated aerobic glycolysis (Warburg metabolism) Energy / biomass restriction Key, repeatedly reported mechanism: shikonin suppresses PKM2 activity and PKM2-driven glycolysis in multiple tumor models, with downstream growth inhibition and apoptosis
2 ROS accumulation / oxidative stress ↑ ROS Redox overload Common upstream trigger that drives mitochondrial dysfunction and regulated cell death programs; often precedes necroptosis/apoptosis signaling
3 Necroptosis core cascade (RIPK1 → RIPK3 → MLKL) Programmed necrotic cell death Strong evidence across cancers (e.g., leukemia and nasopharyngeal carcinoma): shikonin increases RIPK1/RIPK3/MLKL expression/activation; necroptosis inhibitors can blunt the effect
4 Mitochondrial integrity (ΔΨm) Mitochondrial dysfunction ROS-linked depolarization; acts as a pivot into intrinsic apoptosis and other death programs
5 Intrinsic apoptosis (BAX/BAK → Caspase-9/3) Programmed cell death Frequently observed; often framed as ROS → mitochondrial damage → caspase-dependent apoptosis
6 PKM2/STAT3 signaling axis Reduced survival & proliferation signaling In ESCC and related models, shikonin suppresses PKM2-driven glycolysis and down-modulates STAT3 pathway activity
7 NF-κB pathway Reduced pro-survival transcription Reported as part of multi-target suppression of inflammatory/anti-apoptotic programs in several tumor models and reviews
8 PI3K–AKT (± mTOR) Growth & resistance pathway inhibition Often described as sensitizing cells to apoptosis/TRAIL; may be secondary to oxidative stress and metabolic collapse
9 Stress MAPKs (JNK / p38) Pro-death stress signaling Common downstream response to ROS; can reinforce apoptosis and other death outcomes
10 Ferroptosis-related axis (lipid peroxidation; GPX4) ↑ lipid perox / ↓ GPX4 Iron-dependent oxidative death Reported prominently for acetylshikonin (a shikonin derivative): ROS-associated lipid peroxidation with reduced GPX4 expression alongside RIPK1/RIPK3/MLKL activation
11 Endoplasmic reticulum stress (UPR / ERS) Proteotoxic stress signaling Frequently mentioned in leukemia-focused mechanism summaries and broader reviews as contributory to growth arrest and death
12 Multiple regulated death programs (apoptosis / necroptosis / ferroptosis / pyroptosis) ↑ (context-dependent) Broader cell-death engagement Recent reviews emphasize that shikonin can engage several programmed cell death modalities depending on cell context and dosing

IGF-1, insulin-like growth factor-1: Click to Expand ⟱

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.
