Untersuchungen zur endokrinen Regulation der epidermal growth factor receptor (EGFR) Familie im Endometriose in vitro-Modell
This study investigated the EGFR family in an in vitro endometriosis model, exploring its potential role as a survival pathway and its regulation by the estrogen receptor alpha.

This in vitro study characterized the epidermal growth factor receptor (EGFR) family within primary endometriosis cells to determine their role as survival pathways. Researchers identified all four EGFR receptors in both stromal and epithelial cells, observing that while EGF ligand exposure downregulated specific receptors, estrogen withdrawal for up to 72 hours led to an upregulation of all four types. The findings indicate that these receptors function independently of estrogen regulation, potentially explaining high recurrence rates after hormonal therapy by providing an alternative survival mechanism for endometriosis cells. This paper is centrally about endometriosis — specifically investigating the molecular mechanisms of EGFR signaling and its independence from estrogen deprivation in endometriotic tissue models.
