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.

-Disrupts mitochondrial ion gradients → ROS
-Non-thiol, non-NRF2 dominant

Key pathways
-Mitochondrial K⁺ dysregulation
-ROS-mediated apoptosis

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)


Ca+2, Calcium Ion Ca+2: Click to Expand ⟱

Type:
In all eukaryotic cells, intracellular Ca2+ levels are maintained at low resting concentrations (approximately 100 nM) by the activity of the major Ca2+ extrusion system, the plasma membrane Ca2+-ATPase (PMCA), which exchanges extracellular protons (H+) for cytosolic Ca2+.
Indeed, sustained elevation of [Ca2+]C in the form of overload, saturating all Ca2+-dependent effectors, prolonged decrease in [Ca2+]ER, causing ER stress response, and high [Ca2+]M, inducing mitochondrial permeability transition (MPT), are considered to be pro-death factors.
In cancer the Ca2+-handling toolkit undergoes profound remodelling (figure 1) to favour activation of Ca2+-dependent transcription factors, such as the nuclear factor of activated T cells (NFAT), c-Myc, c-Jun, c-Fos that promote hypertrophic growth via induction of the expression of the G1 and G1/S phase transition cyclins (D and E) and associated cyclin-dependent kinases (CDK4 and CDK2).
Thus, cancer cells may evade apoptosis through decreasing calcium influx into the cytoplasm. This can be achieved by either downregulation of the expression of plasma membrane Ca2+-permeable ion channels or by reducing the effectiveness of the signalling pathways that activate these channels. Such protective measures would largely diminish the possibility of Ca2+ overload in response to pro-apoptotic stimuli, thereby impairing the effectiveness of mitochondrial and cytoplasmic apoptotic pathways.
Voltage-Gated Calcium Channels (VGCCs): Overexpression of VGCCs has been associated with increased tumor growth and metastasis in various cancers, including breast and prostate cancer.
Store-Operated Calcium Entry (SOCE): SOCE mechanisms, such as STIM1 and ORAI1, are often upregulated in cancer cells, contributing to enhanced cell survival and proliferation.
High intracellular calcium levels are associated with increased cell proliferation and migration, leading to a poorer prognosis. Calcium signaling can also influence hormone receptor status, affecting treatment responses.
Increased Ca²⁺ signaling is associated with advanced disease and metastasis. Patients with higher CaSR expression may have a worse prognosis due to enhanced tumor growth and resistance to apoptosis. -Ca2+ is an important regulator of the electric charge distribution of bio-membranes.
