Evaluation of Synergic Effects of Molybdenum Disulfide Treatment and Near-Infrared Radiation on Human Mesenchymal Stem Cells.

Introduction

Molybdenum disulfide (MoS2), as an anticancer reagent, can absorb near-infrared (NIR) wavelengths in phototherapy. In the present study, the synergic effect of MoS2 (in nanostructure) and NIR radiation on human mesenchymal stem cells (hMSCs) was evaluated via protein-protein interaction (PPI) network analysis.

Methods

Gene expression profiles of hMSCs were extracted from the Gene Expression Omnibus (GEO) database and analyzed via PPI network analysis. The validity of findings was assessed via the Kaplan-Meier Plotter.

Results

FN1, ACTA2, CCL2, CXCL8, FBN1, and LEP genes were selected as hub genes among 121 recognized differentially expressed genes (DEGs) as the targeted genes by the synergic effects of MoS2 and NIR radiation. Kaplan-Meier Plotter analysis demonstrated that FN1 suppression by MoS2 and NIR radiation can significantly increase the overall survival of patients with gastric cancer, lung cancer, ovarian cancer, and myeloma.

Conclusion

In conclusion, findings indicate that the anticancer property of MoS2 is intensified in the condition of NIR radiation. Therefore, MoS2 is a suitable photosensitizer reagent in photodynamic therapy.
