SCD and age-related macular degeneration: GSEA results showed that the high expression group of SCD in AMD was mainly enriched in GO pathway, such as Cellular response to lipopolysaccharide, Cellular response to molecule of bacterial origin, Monocarboxylic acid transmembrane transporter (Fig 5A), and KEGG pathway, such as Fatty acid metabolism, Biosynthesis of cofactors, and Natural killer cell mediated cytotoxicity (Fig 5B).
