- 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)


MDA, Serum malondialdehyde: Click to Expand ⟱
Source:
Type:
MDA : malondialdehyde. The level of oxidative stress can be measured by assessing the MDA levels.
Since MDA is highly cytotoxic and carcinogenic agent it is frequently used as a biomarker of oxidative stress during major health problems such as cancer, etc.
Malondialdehyde (MDA) is the most widely used agent to estimate the extent of lipid peroxidation. Timely diagnosis of the condition followed by supplementation with antioxidants like beta-carotene, pro-vitamin A, vitamin A, vitamin C, vitamin E, lipoic acid, zinc, selenium, and spirulina can prevent potentially malignant disorders.
MDA is a lipid peroxidation marker
