Our GSEA enrichment analysis demonstrated that the genes of in low SLC13A4 expression group were mainly enriched in immunity, viral diseases, typical tumor pathways and metabolism, while genes in high SLC13A4 high expression group were mainly enriched in metabolism-related activities, such as metabolisms of linoleic acid, retinol, arachidonic acid and alpha linolenic acid. Here, SLC13A4 is linked to viral load.
