| Human Epidermal Neural Crest Stem Cells (hEPI-NCSCs), as a transient population of multipotent migratory stem cells can differentiate into multiple types of neural and non-neural cells and tissues in the body. Here, we tried to determine the role of chemo agents in mediating the stress induced pathways like autophagy and unfolded protein responses (UPR), as well as the migratory potential of NCSCs. hEPI-NCSCs were treated with chemo agents including Dithiothreitol [(DTT) 10µM)], Salinomycin (9mM), Ebselen (10mM), 5-Fluorouracil [(5-FU) 8µM] and Cisplatin (6mM) for 72 hours. The reverse transcription-quantitative polymerase chain reaction (RT- qPCR) and scratch wound healing assays were used to assess the effect of chemo agents on NCSCs function. After treatment with DTT, hEPI-NCSCs upregulated the expression of genes related to autophagy and UPR pathways including LC3, P62 and CHOP. These genes were also overexpressed when NCSCs were treated with Salinomycin. Reverse results were verified by 5-FU, Ebselen and Cisplatin treatment. Salinomycin and Cisplatin upregulated the expression of XBP-1, which down regulated with DTT, 5-FU and Ebselen. Inhibition in migratory capacity of NCSCs was detected following treatment by Salinomycin, 5-FU, Ebselen and Cisplatin. DTT and 5-FU promoted the expression of BDNF, while Salinomycin, Cisplatin and Ebselen treatment reduced its expression. During exposition to DTT, the autophagy pathway was activated, implying that autophagy functions as a survival mechanism for deactivating the inhibitory effects of DTT on the migratory capacity of NCSCs. Chemotherapeutic agents like 5-FU and cisplatin exert cytotoxic effects on NCSCs by suppressing autophagy, UPR pathways, and the migratory potential of NCSCs. | ||
