Effects of polychlorinated biphenyls on estrogen receptor-beta expression in the anteroventral periventricular nucleus.
Polychlorinated biphenyls (PCBs) can disrupt the reproductive axis, particularly when the exposure occurs during the vulnerable developmental periods. Some effects of environmental endocrine disruptors such as PCBs may be exerted through binding to estrogen receptors (ERs). In this study we examined the endocrine-disrupting effects of Aroclor 1221 (a commercial PCB mixture), focusing on its act...
متن کاملEstrogen receptor-dependent sexual differentiation of dopaminergic neurons in the preoptic region of the mouse (anteroventral periventricular nucleusyhypothalamusysexual dimorphismyknockout miceygonadotropin secretion)
Although it has been known for some time that estrogen exerts a profound influence on brain development a definitive demonstration of the role of the classical estrogen receptor (ERa) in sexual differentiation has remained elusive. In the present study we used a sexually dimorphic population of dopaminergic neurons in the anteroventral periventricular nucleus of the hypothalamus (AVPV) to test ...
متن کاملRat Uterine Oxytocin Receptor and Estrogen Receptor α and β mRNA Levels are Regulated by Estrogen Through Multiple Estrogen Receptors
Estrogen action is mediated through several types of receptors (ERs), such as ERα, ERβ and putative membrane ERs. Oxytocin receptor (OTR) and ER expression levels in the rat uterus are regulated by estrogen; however, which types of ERs are involved has not been elucidated. This study examined OTR, ERα and ERβ levels in ovariectomized rats treated with 17β-estradiol (E2), an ERα agonist (PPT), a...
متن کاملSexually dimorphic expression of estrogen receptor beta in the anteroventral periventricular nucleus of the rat preoptic area: implication in luteinizing hormone surge.
Striking sex difference was detected in the expression of estrogen receptor (ER) beta mRNA and protein by nonisotopic in situ hybridization and immunohistochemistry in the anteroventral periventricular nucleus (AVPV) of the rat preoptic area. In females more than in males, a significantly larger number of ERbeta mRNA-positive cells were visualized in the medial-most portion of the AVPV within 5...
متن کاملEstrogen Receptor α Is Required for Maintaining Baseline Renin Expression.
Enzymatic cleavage of angiotensinogen by renin represents the critical rate-limiting step in the production of angiotensin II, but the mechanisms regulating the initial expression of the renin gene remain incomplete. The purpose of this study is to unravel the molecular mechanism controlling renin expression. We identified a subset of nuclear receptors that exhibited an expression pattern simil...
