This study examined the localization and menstrual-cycle–dependent expression of the transcription factor FOXP1 in human eutopic endometrium and compared it with FOXP1 expression in endometriotic lesions and endometrial adenocarcinoma using immunohistochemistry and Western blotting. FOXP1 expression differed between glandular epithelial and stromal compartments, with immunostaining reduced in early secretory compared with mid proliferative stages in the functionalis and reduced in early proliferative compared with early proliferative in the basalis, and overall protein levels higher in mid and late secretory stages than early phases; multiple FOXP1 bands varied across patients. FOXP1 was detected in endometriotic lesions but not in endometrial adenocarcinoma, and a key caveat is that expression patterns varied considerably among patients. This paper is centrally about endometriosis — it reports FOXP1 protein localization and stage-dependent expression in eutopic endometrium and detects FOXP1 in endometriotic lesions.

Abstract

The objective of this study is to examine the localization and expression of FOXP1 in human endometrium during the menstrual cycle and in endometriotic lesions and endometrial adenocarcinoma. FOXP1 protein expression was analyzed by immunohistochemistry and Western blot. FOXP1 expression was significantly different between glandular epithelial and stromal nuclei and cytoplasm in both endometrial functionalis and basalis. FOXP1 immunostaining was significantly reduced in the early secretory stage in comparison to the mid proliferative stage in the functionalis and the early proliferative stage in the basalis. FOXP1 expression was found in endometriotic lesions but not in endometrial adenocarcinoma. Multiple protein bands of FOXP1 were identified, and their presence varied considerably among patients. Protein expression levels were significantly higher in the mid and late secretory stages in comparison to early proliferative and early secretory stages. FOXP1 protein is present in human endometrium with evidence of dependent changes in expression. Similar content being viewed by others
