Abstract:

Objective

This study employed transcriptomic sequencing and bioinformatics analyses to identify differentially expressed genes (DEGs) in mesenchymal stem cells (MSCs) treated with ginsenoside Rb1, in order to uncover key genes with potential therapeutic effects on acute kidney injury(AKI), thereby providing novel insights for AKI treatment.

Methods

In this study, R4.4.2 software was employed to analyze the GSE207667 dataset for identifying DEGs in MSCs after ginsenoside Rb1 treatment.AKI-related key genes were then selected via Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses.The selected key genes were further examined through functional annotations, literature review, and database analysis.

Results

From the MSCs treated with ginsenoside Rb1, 2969 DEGs were identified, comprising 1567 upregulated genes and 1402 downregulated genes(|log2FC|>0.585).GO enrichment analysis revealed that these DEGs were primarily about biological and molecular functions, including the positive regulation of cell population proliferation and apoptotic cell clearance.KEGG analysis further indicated significant enrichment of DEGs in pathways of cytokine-cytokine receptor interaction, IL-17 signaling, ferroptosis, cell senescence, and efferocytosis (P<0.05).Based on functional annotations, this study identified 43 potential key genes related to AKI intervention, and discussed focusing on genes of BMP2, MMP13, ATG5, PTN, and NGF.These genes were implicated in critical biological processes as cell proliferation, apoptosis, inflammation, and tissue repair, and may be closely linked to the mechanism in which MSCs pretreated by ginsenoside Rb1 modulated AKI.

Conclusion

Ginsenoside Rb1 may exert therapeutic effects on AKI by modulating biological processes of cell proliferation and apoptosis in MSCs.The five key genes identified in this study (BMP2, MMP13, ATG5, PTN, and NGF) may offer potential targets for the application of ginsenoside Rb1-treated MSCs in AKI therapy.
