Abstract/OtherAbstract:
The effect of long-term exposure to bisphenol-A (BPA) on estrogen receptor-alpha (ER) immunoreactivity was studied in the medial preoptic area, arcuate nucleus and the ventromedial nucleus of the hypothalamus of estrous cycling and lactating female rats. Pregnant/lactating or estrous cycling rats were exposed to BPA (40 mg/Kg/day) or peanut oil. Lactating females showed fewer ER-immunoreactive cells than non-lactating females in the medial preoptic area and ventromedial nucleus of the hypothalamus. BPA induced an increase in ER-immunoreactive cells in the medial preoptic nucleus irrespective of lactation. BPA only induced a decrease in ER-immunoreactive cells in the arcuate nucleus of the lactating group; oil induced an increase in ER-immunoreactive cells in the lactating with respect to non-lactating group. The results demonstrate that exposure of adult females to BPA modifies the number of ERs.
