The best I can understand, they're describing endometrial hyperplasia, a result of excess estrogen, a steroid hormone that translocates to the nucleus and binds its transcription factor.

mousie  My exact thinking also! +4  
sympathetikey  Ditto. +  
meningitis  My thought as well but the answer says: "Binding of ligand to Nuclear transcription factor" and I thought to myself: "Estrogen Receptors aren't transcription factors.. they are receptors with Transcription Factor function that bind to the ER Element and recruit more Transcription Factors". Can anyone explain what I am missing? Am overthinking things? +  
criovoly  You are overthinking it, Steroid hormones receptor is found intracellular in the cytoplasm then they are translocated to the nucleus where they regulate gene transcription. HOPE THIS HELPS +2  
eve1000  Could this be due to the PTEN gene being linked to endometrial hyperplasia? +
