Abstract
Salinomycin is usually applied in stock breading but has also been described as a promising agent against cancer stem cells (CSC). However, knowledge about the toxicity of this ionophor substance is incomplete. The aim of this study was to investigate cyto- and genotoxic effects of salinomycin in human non-malignant cells.Primary human nasal mucosa cells (monolayer and mini organ cultures) and peripheral blood lymphocytes from 10 individuals were used to study the cytotoxic effects of salinomycin (0.1–175μM) by annexin–propidiumiodide- and MTT-test. The comet assay was performed to evaluate DNA damage. Additionally, the secretion of interleukin-8 was analyzed by ELISA.Flow cytometry and MTT assay revealed significant cytotoxic effects in nasal mucosa cells and lymphocytes at low salinomycin concentrations of 10–20μM. No genotoxic effects could be observed. IL-8 secretion was elevated at 5μM.Salinomycin-induced cytotoxic and pro-inflammatory effects were seen at concentrations relevant for anti-cancer treatment. Concurrent to the evaluation of salinomycin application in experimental oncology, adverse effects in non-malignant cells need to be monitored and reduced as much as possible. Further studies are also warranted to evaluate the toxic effects in a variety of human cell systems, e.g., liver, kidney and muscle cells.
