Background/Aim:
To optimize the therapeutic potential of stem cells in stem cell therapy for neurological diseases, it is crucial to enhance the differentiation, migration, and neural network formation of stem cells, and to eliminate uncertain cell differentiation and proliferation factors. Several studies have shown that reactive oxygen species (ROS) are important factors in the regulation of neurogenesis, and Prx II (Peroxiredoxin II) is a gene that regulates ROS.
Materials And Methods:
As the entry point in this study to conduct a bioinformatics analysis of the sequencing results of Prx II+/+ dermal mesenchymal stem cells (DMSCs) and Prx II-/- DMSCs. lncRNA/miRNA/mRNA networks were then constructed and preliminarily verified in RT-qPCR experiments.
Results:
In this study, a total of 11 hub genes (Gria1, Nrcam, Sox10, Snap25, Cntn2, Dlg2, Ngf, Ntrk3, Amph, Syt1, and Cd24a), eight miRNAs (miRNA-4661, miRNA-34a, miRNA-185, miRNA-34b-5p, miRNA-34c, miRNA-449a, miRNA-449b, miRNA-449c) and 12 lncRNAs (Dubr, Gas5, Gm20427, Gm26917, Gm42547, Gm8066, Kcnq1ot1, Malat1, Mir17hg, Neat1, Rian, and Tug1) were predicted in lncRNA/miRNA/mRNA network.
Conclusion:
The regulatory mechanism of Prx II in the differentiation of DMSCs into neurons through ROS was explored, and a theoretical basis was determined that can be applied in future research on nervous system diseases and the clinical applications of stem cells.
