Signal transduction-related genes (two-component system and HIF-1 signalling pathway) were overexpressed in the elasnin treatment group, whereas many genes related to membrane transport (ABC transporters, phosphotransferase system, and bacterial secretion system), quorum sensing, and especially Staphylococcus infection and β-lactam resistance were downregulated. Here, ABCG2 is linked to staphylococcus aureus infection.
