IL4 and adenomyosis: Integrative enrichment analysis using the adenomyosis gene list with 424 genes provided additional candidate pathways to be associated with altered cytokine responses in adenomyosis and endometriosis, including “interleukin-4 and interleukin-13 signalling”, which was also identified in our previous study [18] and could be attributable to the Reactome pathway database being used as an ontology source in both studies, “regulation of TNF superfamily cytokine production” and “interleukin-10 signalling”.
