The upregulated DEGs were mainly enriched in the oestrogen signalling pathway, ether lipid metabolism, and Staphylococcus aureus infection (Figure 2B) and were mainly associated with the antimicrobial humoral response, peptide cross-linking, epidermal cell differentiation and development, epidermis development, Golgi lumen, desmosome, serine hydrolase activity, serine-type peptidase activity, and peptidase regulator activity, among other terms (Figures 2C–E). Here, LAP3 is linked to staphylococcus aureus infection.
