abstract：:Estrogen receptor (ER) expression and regulation is vital to the correct functioning of the neuroendocrine brain. Islet-1 (Isl-1) is a LIM homeodomain-containing transcription factor that has been implicated in neuronal differentiation, is located in the hypothalamus, and can alter ER function in vitro. We have determ...
