While some proteins such as IL-1β, IL-6, IL-4, and VEGF are largely evaluated, our data are suggestive of further investigation on proteins such as PGE1 and AVP. Our study prioritizes potential biomarkers and key targets, and further assessing them in endometriosis could help for the development of diagnostic tools and therapeutic strategies for endometriosis. Here, IL4 is linked to endometriosis.
