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.

Rank Pathway / Target Axis Direction Primary Effect Notes / Cancer Relevance 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)

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)

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)

Type:
Caspases are a cysteine protease that speed up a chemical reaction via pointing their target substrates following an aspartic acid residue.1 They are grouped into apoptotic (caspase-2, 3, 6, 7, 8, 9 and 10) and inflammatory (caspase-1, 4, 5, 11 and 12) mediated caspases.
Caspase-1 may have both tumorigenic or antitumorigenic effects on cancer development and progression, but it depends on the type of inflammasome, methodology, and cancer.
Catalase is an enzyme found in nearly all living cells exposed to oxygen. Its primary role is to protect cells from oxidative damage by catalyzing the conversion of hydrogen peroxide (H₂O₂), a potentially damaging byproduct of metabolism, into water (H₂O) and oxygen (O₂). This detoxification process is crucial because excess H₂O₂ can lead to the formation of reactive oxygen species (ROS) that damage proteins, lipids, and DNA.

Catalase and Cancer
Oxidative Stress and Cancer:
Cancer cells often experience increased levels of oxidative stress due to rapid proliferation and metabolic changes. This stress can lead to DNA damage, promoting tumorigenesis.
Catalase helps mitigate oxidative stress, and its expression can influence the survival and proliferation of cancer cells.
Expression Levels in Different Cancers:
Overexpression: In some cancers, such as breast cancer and certain types of leukemia, catalase may be overexpressed. This overexpression can help cancer cells survive in oxidative environments, potentially leading to more aggressive tumor behavior.
Downregulation: Conversely, in other cancers, such as colorectal cancer, reduced catalase expression has been observed. This downregulation can lead to increased oxidative stress, contributing to tumor progression and metastasis.
Prognostic Implications:
Survival Rates: Studies have shown that high levels of catalase expression can be associated with poor prognosis in certain cancers, as it may enable cancer cells to resist apoptosis (programmed cell death) induced by oxidative stress.

Some types of cancer cells have been reported to exhibit lower catalase activity, possibly increasing their vulnerability to oxidative damage under certain conditions. This vulnerability has even been exploited in some therapeutic strategies (for example, approaches that generate excess H₂O₂ or other ROS specifically targeting cancer cells have been researched).
