Sal, salinomycin: Click to Expand ⟱
Features:
Salinomycin is a polyether ionophore antibiotic that is produced by the bacterium Streptomyces albus. It was first isolated in 1979 and has been found to have a range of biological activities, including antibacterial, antifungal, and anticancer properties.
It has been shown to induce apoptosis (programmed cell death) in a range of cancer cell lines, including breast, lung, and colon cancer cells. Salinomycin has also been found to inhibit the growth of cancer stem cells.

Actions:
-Strong activity against cancer stem cells
-Disrupts mitochondrial ion gradients → ROS
-Non-thiol, non-NRF2 dominant

Key pathways
-Mitochondrial K⁺ dysregulation
-ROS-mediated apoptosis
-Wnt/β-catenin inhibition

Chemo relevance
-Generally compatible or synergistic
-Not a redox buffer

Rank Pathway / Target Axis Direction Primary Effect Notes / Cancer Relevance Ref
1 K+ ionophore activity / ionic homeostasis ↑ K+ transport (ionophore) / ↓ intracellular K+ homeostasis Electrochemical disruption Salinomycin is directly described as a potassium ionophore in mechanistic studies of its anticancer effects (ref)
2 Cancer stem cell (CSC) fraction / stemness programs ↓ CSC proportion / tumor-initiating capacity Selective CSC depletion Landmark study showing salinomycin strongly reduces CSC proportion (e.g., >100-fold vs paclitaxel in their assay context) and inhibits tumor growth in vivo (ref)
3 Wnt/β-catenin signaling ↓ Loss of self-renewal signaling Primary mechanistic paper identifying salinomycin as an inhibitor of the Wnt signaling cascade (ref)
4 Wnt co-receptor LRP6 (Wnt pathway control point) ↓ LRP6 / ↓ Wnt signaling Wnt pathway suppression Shows salinomycin suppresses LRP6 expression at concentrations relevant to growth inhibition, linking activity to Wnt/β-catenin suppression (ref)
5 Autophagic flux + lysosomal proteolysis ↓ autophagic flux (blocked) / ↓ lysosomal proteolytic activity Abortive autophagy / stress accumulation Demonstrates salinomycin blocks autophagic flux and lysosomal proteolytic activity in breast cancer CSC and non-CSC populations (ref)
6 ER stress / UPR (ATF4 → CHOP/DDIT3) ↑ ER stress / ↑ CHOP axis Proteotoxic stress signaling Shows salinomycin stimulates ER stress and mediates autophagy through the ATF4–CHOP–TRIB3 axis (ref)
7 AKT–mTOR survival signaling (via TRIB3) ↓ AKT / ↓ mTOR signaling Reduced survival + altered autophagy control Same mechanistic work links ER stress activation to TRIB3-mediated inhibition of AKT1–mTOR signaling after salinomycin exposure (ref)
8 ROS generation and ROS-linked lysosomal dysfunction ↑ ROS Oxidative stress amplification Demonstrates salinomycin-induced ROS and connects ROS to lysosomal membrane permeability and impaired autophagy flux (ref)
9 Mitochondrial apoptosis (caspase cascade) ↑ Caspase-9/3 activation Programmed cell death Shows salinomycin triggers caspase-dependent apoptosis involving caspases (including 9 and 3) in a salinomycin toxicity/mechanism study (demonstrates directionality for caspase activation) (ref)
10 EMT phenotype ↑ E-cadherin / ↓ vimentin (EMT suppressed) Reduced migration/invasion Reports salinomycin increases epithelial markers and decreases mesenchymal markers in a dose-dependent manner, with reduced migration/invasion (ref)
11 ABC transporter–mediated multidrug resistance ↓ functional MDR phenotype Overcomes drug resistance Directly reports salinomycin overcomes ABC transporter–mediated multidrug/apoptosis resistance in leukemia stem cell–like cells (ref)
12 Ferroptosis susceptibility (GPX4 axis) in CSC context ↑ ferroptosis (context-dependent) Non-apoptotic oxidative death modality Reports salinomycin induces ferroptosis in a CSC context via a pathway converging on GPX4/GPX activity regulation (directionality: ferroptosis induction by salinomycin in that model) (ref)


SOD1, superoxide dismutase 1: Click to Expand ⟱
Source:
Type:
SOD1 (superoxide dismutase 1) is a key antioxidant enzyme that catalyzes the dismutation of superoxide radicals into oxygen and hydrogen peroxide.

In several cancers including breast, lung, HCC, and others, alterations in SOD1 expression have been observed, reflecting its role in managing oxidative stress.
• Elevated SOD1 levels are sometimes associated with aggressive tumor behavior, therapy resistance, or decreased apoptosis due to enhanced ROS detoxification.
• Conversely, the protective role of antioxidants can also mitigate oxidative mutation loads, leading to context-dependent and occasionally favorable outcomes.

In non-small cell lung cancer (NSCLC), increased SOD1 levels have been reported in some cohorts, potentially as a mechanism to cope with high reactive oxygen species (ROS) levels.
