In addition to regulating estrogen receptor-dependent gene expression, 17 beta-estradiol (E-2) can directly influence intracellular signaling. In primary cultured cerebellar neurons, E-2 was previously shown to regulate growth and oncotic cell death via rapid stimulation of ERK1/2 signaling. Here we show that ERK1/2 signaling in the cerebellum of neonatal and mature rats was rapidly responsive to E-2 and during development to the environmental estrogen bisphenol A (BPA).
