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)


MOMP, Mitochondrial Outer Membrane Permeabilization: Click to Expand ⟱
Source:
Type:
MOMP is the point-of-no-return decision step of intrinsic apoptosis. It is the event in which the mitochondrial outer membrane becomes permeable, allowing release of pro-death factors that irreversibly commit a cell to die. Cancer progression is characterized by systematic suppression, buffering, or decoupling of MOMP from lethal execution.

MOMP occurs when BAX and/or BAK oligomerize in the mitochondrial outer membrane, forming pores that release:
-Cytochrome c → apoptosome → caspase-9
-Smac/DIABLO → IAP neutralization
-Other apoptogenic factors (e.g., Omi/HtrA2)
Once sufficient mitochondria undergo MOMP, cell death is inevitable (even if caspases are later inhibited).
Redox, Metabolism, and MOMP (Critical)
-High xCT / GSH → suppress mitochondrial ROS → MOMP ↓
-Autophagic flux → removes damaged mitochondria → MOMP ↓
-Pro-oxidant overload → mitochondrial dysfunction → MOMP ↑
