- 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
Rank Pathway / Target Axis Direction Primary Effect Notes / Cancer Relevance Ref
1 PKM2-mediated aerobic glycolysis (Warburg metabolism) ↓ PKM2 activity / ↓ glycolysis Energy & biomass restriction Demonstrates shikonin (and analogs) inhibit cancer glycolysis, reducing glucose consumption/lactate production via PKM2 targeting (ref)
2 PKM2 → STAT3 signaling axis ↓ PKM2-driven signaling / ↓ STAT3 pathway Reduced survival & proliferation ESCC study: shikonin suppresses PKM2-mediated aerobic glycolysis and regulates PKM2/STAT3 signaling (ref)
3 Necroptosis (RIPK1 → RIPK3 → MLKL) ↑ RIPK1/RIPK3/MLKL Programmed necrotic cell death Nasopharyngeal carcinoma: shikonin induces necroptosis with upregulation of RIPK1/RIPK3/MLKL (with ROS involvement) (ref)
4 ROS accumulation ↑ ROS Oxidative stress trigger Colon cancer model: shikonin increases intracellular ROS; ROS functions upstream of apoptosis (ref)
5 Mitochondrial apoptosis (Caspase-9/3) ↑ Caspase-9/3 Programmed cell death Same colon cancer study shows shikonin increases caspase-3 and caspase-9 activity (mitochondria-mediated apoptosis) (ref)
6 ER stress / UPR (PERK → eIF2α → CHOP) ↑ Proteotoxic stress apoptosis signaling Colon cancer: shikonin-induced apoptosis mediated by PERK/eIF2α/CHOP ER-stress pathway (ref)
7 Autophagic flux (autophagosome–lysosome completion) ↓ autophagic flux (blocked) ROS + apoptosis amplification Colorectal cancer: shikonin induces ROS and apoptosis by inhibiting autophagic flux (ref)
8 NF-κB signaling ↓ NF-κB activity Reduced pro-survival transcription Pancreatic cancer xenograft/mechanistic study: shikonin suppresses NF-κB activity and NF-κB–regulated gene products (ref)
9 PI3K–AKT–mTOR (stemness / chemoresistance axis) ↓ PI3K/AKT/mTOR Reduced survival & stemness Chemoresistant lung cancer CSC context: shikonin attenuates PI3K–Akt–mTOR pathway and reduces cancer stemness (ref)
10 Cell cycle control (p21; G2/M arrest) ↑ p21 / ↑ G2/M arrest Proliferation block Gastric cancer (AGS): shikonin induces cell-cycle arrest linked to p21 regulation (ref)
11 Invasion / metastasis programs (NF-κB-linked) ↓ invasion Anti-invasive phenotype Reports shikonin inhibits tumor invasion via down-regulation of NF-κB–related mechanisms in a high-metastatic tumor model (ref)
12 Chemosensitization via glycolysis suppression ↓ glycolysis / ↑ cisplatin sensitivity Combination benefit NSCLC: shikonin inhibits glycolysis and sensitizes cells to cisplatin (explicitly connecting metabolic suppression to chemosensitization) (ref)


IL1β, interleukin-1 beta: Click to Expand ⟱

Type:
The term "IL-1" is often used as an umbrella term for the interleukin-1 family, which includes multiple cytokines. The two best-known members are IL-1α and IL-1β.
IL-1β is secreted from cells and plays a major systemic role in inflammation. It is a crucial mediator in the inflammatory response and is involved in the fever response, activation of endothelial cells, and leukocyte recruitment.
Its increased expression is commonly linked to:
  – Promotion of a pro-inflammatory microenvironment that supports tumor growth.
  – Enhanced angiogenesis, invasion, and metastasis.
  – Recruitment of myeloid cells that may further suppress antitumor immunity.

High expression of either tends to be associated with a more aggressive phenotype and worse prognosis in many cancer types.
