Ovarian cancer is the most lethal gynecologic malignancy, and ovarian cancer stem cells (CSCs) serve a pivotal function in the metastasis and recurrence of ovarian cancer. Multiple previous studies have validated CD133 as a marker of ovarian CSCs. Although salinomycin is a promising therapeutic agent that has been demonstrated to kill CSCs in various types of cancer, poor aqueous solubility hampers its clinical application. The present study used salinomycin-loaded poly(lactic-co-glycolic acid)-poly(ethylene glycol) nanoparticles conjugated with CD133 antibodies (CD133-SAL-NP) to eliminate CD133+ ovarian CSCs...

Cadmium (Cd) is an environmental pollutant shown to induce multi organ dysfunction. In this study we present novel data about the effects of meso-2,3-dimercaptosuccinic acid (DMSA), monensin and salinomycin on the concentration of Cd in skeletal muscles of mice exposed to Cd (II) acetate treatment for 14 days. The impact of Cd and the chelating agents on the endogenous concentrations of calcium (Ca), copper (Cu), iron (Fe), magnesium (Mg), phosphorous (P), selenium (Se) and zinc (Zn) was also investigated. Subacute exposure of mice to Cd (II) acetate resulted in a significant accumulation of the toxic metal ion in the skeletal muscles compared to the untreated controls...

Although several epigenetic modulating drugs are suggested to target cancer stem cells (CSCs), additional identification of anti-CSC drugs is still necessary. Here we showed that JIB-04, a pan-selective inhibitor of histone demethylase(s), was identified as a small molecule that selectively target colorectal CSCs. Our data showed that JIB-04 is capable of reducing self-renewal and stemness of colorectal CSCs in three different colorectal cancer cell lines. JIB-04 significantly attenuated CSC tumorsphere formation, growth/relapse, invasion, and migration in vitro...

Recently, Salinomycin (SAL) has been reported to inhibit proliferation and induce apoptosis in various tumors. The aim of this study was to deliver SAL to orthotopic model of pancreatic cancer by the aid of poly (lactic-co-glycolic acid) (PLGA) nanoparticles. The nanoparticles were physico-chemically characterized and evaluated for cytotoxicity on Luciferase-transduced AsPC-1 cells in vitro as well as implanted orthotopically into the pancreas of nude mice. SAL (3.5 mg/kg every other day) blocked tumor growth by 52% compared to the control group after 3 weeks of therapy...

The use of graphene to target and eliminate cancer stem cells (CSCs) is an alternative approach to conventional chemotherapy. We show the biomolecule-mediated synthesis of reduced graphene oxide-silver nanoparticle nanocomposites (rGO-Ag) using R-phycoerythrin (RPE); the resulting RPE-rGO-Ag was evaluated in human ovarian cancer cells and ovarian cancer stem cells (OvCSCs). The synthesized RPE-rGO-Ag nanocomposite (referred to as rGO-Ag) was characterized using various analytical techniques. rGO-Ag showed significant toxicity towards both ovarian cancer cells and OvCSCs...

Chondrosarcoma (CS) is a cartilage malignancy of adulthood that is treated by surgery alone, since chemotherapy is considered ineffective. Unfortunately, a large proportion of patients with CS develop lung metastases, and several die of the disease. In this study, we compared 3D-spheroid cultures and conventional cell monolayer models in order to identify the best way to select anticancer agents that could be effective for the systemic control of CS. Using SW1353 cells, we developed a three-dimensional (3D) in vitro culture model to mimic in vivo features of CS microenvironment and evaluated the efficacy of different drugs to modulate CS cell proliferation and survival in 2D versus 3D-cultures...

Initiation and recurrence of lung cancer, the most fatal cancer worldwide, are attributed to lung cancer stem cells (CSCs). Evidence suggests that cancer cells can be turned into CSCs in a spontaneous way, and therefore simultaneous elimination of lung CSCs and cancer cells is crucial to achieve effective therapy of lung cancer. In lung cancer, epidermal growth factor receptor (EGFR) is overexpressed in both CSCs and cancer cells. The present study developed salinomycin poly(ethylene glycol) 2000-distearoylphosphatidylethanolamine nanomicelles conjugated with EGFR aptamers (M-SAL-EGFR) to kill lung CSCs and cancer cells...

RATIONALE: Salinomycin is an ionophore antibiotic with potential anticancer activity. The history of its use in veterinary medicine shows large differences in species susceptibility to its toxicity. At the same time, the results of research to date suggest a correlation between the extent and pathways of ionophore biotransformation and its toxicity. The biotransformation pattern of salinomycin has not been studied so far. METHODS: Extracts from culture media of human hepatoma cells (HepG2) exposed to salinomycin were analysed with two mass spectrometry techniques...

The antibiotic drug salinomycin has been reported to mediate cancer cell-specific cytotoxicity, especially regarding cancer stem cells. Since salinomycin has also been reported to arrest cancer cells in the G2 phase, it may have possible radiosensitizing effects. Radiotherapy is a common therapeutic strategy for head and neck squamous cell carcinoma (HNSCC). The aim of the present study was to evaluate a possible influence of salinomycin on the radiosensitivity of the HNSCC cell line HLaC-78 in vitro. HLaC-78 cells were incubated with 5 µM salinomycin or control medium for 24 h and then received 5-Gy irradiation...

Since Salinomycin (Sal) emerged its ability to target breast cancer stem cells in 2009, numerous experiments have been carried out to test Sal's anticancer effects. What deserve to be mentioned is that Sal can efficiently induce proliferation inhibition, cell death and metastasis suppression against human cancers from different origins both in vivo and in vitro without causing serious side effects as the conventional chemotherapeutical drugs on the body. There may be novel cell death pathways involving the anticancer effects of Sal except the conventional pathways, such as autophagic pathway...

Introduction: Cholangiocarcinoma is characterized by aggressive tumor growth, high recurrence rates, and resistance against common chemotherapeutical regimes. The polyether-antibiotic Salinomycin is a promising drug in cancer therapy because of its ability to overcome apoptosis resistance of cancer cells and its selectivity against cancer stem cells. Here, we investigated the effectiveness of Salinomycin against cholangiocarcinoma in vivo , and analyzed interference of Salinomycin with autophagic flux in human cholangiocarcinoma cells...

Osteosarcoma is a common childhood bone cancer with a poor survival rate. Osteosarcoma cancer stem cells (CSCs) contribute to the recurrence, drug resistance and metastasis of this disease. Previous evidence suggested that cancer cells are able to spontaneously turn into CSCs, thus it is crucial to simultaneously target osteosarcoma cells and CSCs. Our previous studies have demonstrated that salinomycin preferably eliminated osteosarcoma CSCs. In addition, amplification of the epidermal growth factor receptor (EGFR) is a common genetic aberration in osteosarcoma, and thus EGFR is a promising target in osteosarcoma...

Melanoma is the deadliest type of skin cancer. CD20+ melanoma stem cells (CSCs) are pivotal for metastasis and initiation of melanoma. Therefore, selective elimination of CD20+ melanoma CSCs represents an effective treatment to eradicate melanoma. Salinomycin has emerged as an effective drug toward various CSCs. Due to its poor solubility, its therapeutic efficacy against melanoma CSCs has never been evaluated. In order to target CD20+ melanoma CSCs, we designed salinomycin-loaded lipid-polymer nanoparticles with anti-CD20 aptamers (CD20-SA-NPs)...

Salinomycin (SAL) and monensin (MON) are polyether ionophore antibiotics commonly used in veterinary medicine. They are known from their anti-cancer activity against various types of cancer cells, including those that display multi-drug resistance as well as cancer stem cells. In order to increase the biological activity profile and reduce toxicity against normal cells, while retaining the activities in the micromolar range, a library of ester and amide derivatives of SAL was synthesized and previously reported...
