HSP90AA1 and endometriosis: Analysis of the differentially expressed proteins using the eutopic endometrium has revealed the presence of structural proteins (vimentin, actins), stress response proteins (peroxiredoxins, HSP B1, HSP70, HSP90) or signaling proteins (14-3-3 proteins, annexins), suggesting they might play an important role in the pathology of endometriosis [55,56,57].
