摘要
BACKGROUND The endoplasmic reticulum(ER)is closely related to a wide range of cellular functions and is a key component to maintain and restore metabolic health.Type 2 diabetes mellitus(T2DM)is a serious threat to human health,but the ER stress(ERS)-related mechanisms in T2DM have not been fully elucidated.AIM To identify potential ERS-related mechanisms and crucial biomarkers in T2DM.METHODS We conducted gene set enrichment analysis(GSEA)and gene set variation analysis(GSVA)in myoblast and myotube form GSE166502,and obtained the differentially expressed genes(DEGs).After intersecting with ERS-related genes,we obtained ERS-related DEGs.Finally,functional analyses,immune infiltration,and several networks were established.RESULTS Through GSEA and GSVA,we identified several metabolic and immune-related pathways.We obtained 227 ERS-related DEGs and constructed several important networks that help to understand the mechanisms and treatment of T2DM.Finally,memory CD4^(+)T cells accounted for the largest proportion of immune cells.CONCLUSION This study revealed ERS-related mechanisms in T2DM,which might contribute to new ideas and insights into the mechanisms and treatment of T2DM.
