Here, we report on the effects of developmental exposure to two common estrogenic pollutants, bisphenol A and ethinyl estradiol on sexually dimorphic, non-reproductive behavior. Mice (Mus musculus domesticus) were exposed to environmentally relevant levels of these chemicals (2 and 200 μg/kg/day for bisphenol A and 5 μg/kg/day for ethinyl estradiol) throughout prenatal and early postnatal development. As adults, the animals were observed in a variety of tests measuring sexually dimorphic behaviors including short-term spatial memory (in a radial-arm maze and a Barnes maze) and anxiety (in an elevated-plus maze and a light/dark preference chamber). Developmental exposure to ethinyl estradiol was found to masculinize behavior in all of the assays used. Bisphenol A increased anxious behavior in a dose-dependent fashion but had no effect on spatial memory. These results indicate that non-reproductive, sexually dimorphic behavior is sensitive to endocrine disruption. In addition, these experiments suggest that both humans and wildlife are being exposed to levels of these endocrine disrupting compounds that are sufficient to disrupt the development of the nervous system and that may have permanent consequences on sexually dimorphic behaviors.}, number={1}, journal={HORMONES AND BEHAVIOR}, author={Ryan, Bryce C. and Vandenbergh, John G.}, year={2006}, month={Jun}, pages={85–93} }

Pine voles, a novel experimental mammal, were chosen because they display strong monogamous pair bonding. Female pine voles were orally administered estrogenic diethylstilbestrol (DES) and methoxychlor (MXC) or oil control throughout gestation and lactation of pups. Exposed pups were tested as adults. Preference for the mate and maternal behaviors were assessed. While the ability to form partner preferences was intact, DES-exposed females showed increased aggression toward a stranger, while MXC exposed females showed a strong trend toward spending more time alone. Oxytocin (OT) receptor binding in the brain was assessed for possible effects on this behaviorally important neuropeptide signaling system.

Pregnant rats were treated with either corn oil, 75 mg/kg/day of linuron, 500 mg/kg/day of BBP, or a combination of 75 mg/kg/day linuron and 500 mg/kg/day BBP from gestational Day 14 to 18. A cohort of fetuses was removed to assess male testicular T and progesterone production, testicular T concentrations, and whole-body T concentrations. Male offspring from the remaining litters were assessed for AGD and number of areolae and then examined for alterations as young adults. Prenatal exposure to either linuron or BBP or BBP + linuron decreased T production and caused alterations to androgen-organized tissues in a dose-additive manner. Furthermore, treatment-related changes to neonatal AGD and infant areolae significantly correlated with adult AGD, nipple retention, reproductive malformations, and reproductive organ and tissue weights. In general, consideration of the dose-response curves for the antiandrogenic effects suggests that these responses were dose additive rather than synergistic responses.

In rats, play behavior is sexually dimorphic. Administration of exogenous androgens during the perinatal period results in masculine-like play behavior of juveniles. Recently, there has been increasing concern about the potential for environmental endocrine-disrupting chemicals (EDCs) to alter sexual differentiation in mammals. One such EDC is the fungicide and androgen receptor (AR) antagonist, vinclozolin. We tested whether developmental exposure to an EDC could alter androgen-dependent behaviors such as play. To examine this possibility, neonatal male rats were injected from Postnatal Days (PND) 2 to 3 with corn oil, pharmacological antiandrogen flutamide (50 mg/kg/day) or vinclozolin (200 mg/kg/day); whereas neonatal females were treated either with corn oil or testosterone propionate (TP, 250 microg/kg/day). At PNDs 36-37, animals were observed for social play. Behaviors associated with general social activity, such as sniffing and dorsal contact, were unaffected by treatment or sex. However, play behavior in males treated with flutamide or vinclozolin was significantly reduced to near-female levels when compared to control males. Play behavior in females exposed to TP during the neonatal period was significantly increased when compared with control females. Hence, this study suggests that perinatal exposure to vinclozolin, an environmental antiandrogen, can alter androgen-dependent behavior, such as play, in the male rat.}, number={2}, journal={PHYSIOLOGY & BEHAVIOR}, author={Hotchkiss, AK and Ostby, JS and Vandenbergh, JG and Gray, LE}, year={2003}, month={Jul}, pages={151–156} }

Male fetuses exposed to antiandrogens during perinatal life are permanently demasculinized in their morphology and physiology, whereas exposure to exogenous androgens permanently masculinizes females. In some litter-bearing species, proximity(italic) in utero(/italic) of females to males can partially masculinize female siblings and alter their responsiveness to endocrine-disrupting compounds. However, in our strain of rat (CD-SD Charles River), intrauterine position does not significantly influence testosterone concentrations and anogenital distance of fetuses. In comparison, administration of testosterone propionate to pregnant females, at doses that doubled fetal female testosterone levels, did masculinize the reproductive system. Discovery of androgen-active chemicals in the environment has placed increased emphasis on describing the reproductive and behavioral effects of both natural and environmental androgens and antiandrogens. Recently, the effects of an antiandrogen, vinclozolin, on the brain and behavior were cited as a special concern by the U.S. Environmental Protection Agency in its risk assessment of this pesticide. In rats, one such behavior that is perinatally organized by androgens is social play. Males play more than females, and administration of exogenous androgens during the neonatal period alters the juvenile expression of this sexually dimorphic behavior. Vinclozolin is an androgen receptor antagonist that inhibits androgen-dependent tissue growth in vivo. We were interested in whether developmental exposure to vinclozolin could also alter androgen-dependent behaviors such as play. Neonatal male rats were injected on postnatal days (PNDs) 2 and 3 with corn oil, the pharmacologic antiandrogen flutamide (50 mg/kg), or vinclozolin (200 mg/kg). On PNDs 36-37 animals were observed for social play. Behaviors associated with general social activity such as sniffing and dorsal contact were unaffected by treatment. However, play behavior in males treated with flutamide or vinclozolin was significantly reduced, resembling levels of play characteristic of females rather than untreated males. Therefore, this study demonstrates that perinatal exposure to vinclozolin, an environmental antiandrogen, can alter androgen-dependent play behavior in the male rat.}, journal={ENVIRONMENTAL HEALTH PERSPECTIVES}, author={Hotchkiss, AK and Ostby, JS and Vandenbergh, JG and Gray, LE}, year={2002}, month={Jun}, pages={435–439} }

Olfactory signaling involves odorant receptor-mediated activation of G(olf), a homologue of G(s), on the dendrites of olfactory neurons. Olfactory receptor cells, however, also express Galpha(i2) and Galpha(o) on their axons, with all neurons expressing G(o) and a subset G(i2). Despite their abundance, possible contributions of G(o) and G(i2) to chemoreception remain unexplored. We investigated whether homologous recombinant mice deficient in the alpha subunit of G(o) are able to respond to odorants, whether possible olfactory impairments are dependent on genetic background, and whether formation of glomeruli in their olfactory bulbs is compromised. In an olfactory habituation/dishabituation test, G(o)-/- mice were unresponsive when exposed to odorants. Analysis of variance shows that performance of G(o)+/- mice crossed into the CD-1 background is also diminished in this test compared to their G(o)+/+ counterparts. Following food deprivation, G(o)-/- mice in the 129 Sv-ter/C57BL/6 genetic background were unable to locate a buried food pellet until they were approximately 10 weeks of age after which they performed as well as their litter mate controls. However, CD-1 G(o)-/- mice could locate a buried food pellet even when tested immediately after weaning. Despite their compromised olfactory responsiveness, histological examination did not reveal gross alterations in the olfactory bulbs of G(o)-/- mice.

In litter-bearing mammals, fetuses develop in utero and may be subjected to differing hormonal environments based upon the sex of neighboring fetuses. Female fetuses developing between two males tend to show masculinized anatomical, physiological and behavioral traits as adults. Female fetuses developing without adjacent males, on the other hand, tend to show more feminized traits as adults. These traits include permanently altered hormone levels, reproductive organs, aggressive behaviors, secondary sex ratios and susceptibility to endocrine disruption. This intrauterine effect is due to the transfer of testosterone from male fetuses to adjacent fetuses. While these effects have been most clearly demonstrated in mice, other rodents and swine also show intrauterine position (IUP) effects. Some of these effects are similar to the influence of prenatal stress on adult phenotypes. A few reports on human twins suggest that variability in some masculine and feminine traits may be due to intrauterine hormonal signals.

Differential responsiveness to these agents has been observed between different species and extends to interindividual differences within a species and between different tissues as well. In cases where they have been identified, the biologic and molecular mechanisms underlying this specificity are quite diverse. Determinants of species specificity include differences that exist in receptor binding, gene transcription, and cellular responses to endocrine-active compounds between species. Interindividual differences in responsiveness may be determined at the level of genetic polymorphisms in hormone-metabolizing enzymes, hormone receptors, and in those genes that are transactivated by these receptors, as well as during changing windows of susceptibility that occur as a function of age, such as prenatal and postmenopausal exposures. Extrinsic factors such as diet can also impact individual susceptibility to endocrine-active agents. Tissue-specific determinants of susceptibility are well documented, but little is known regarding the mechanisms underlying these different responses. Differences in the expression of accessory proteins for steroid hormone receptors and different patterns of receptor expression, estrogen receptor alpha and estrogen receptor beta; for example, may contribute to tissue specificity, as may differences in the pattern of expression of other genes such as hormone-metabolizing enzymes.

We studied groups of pine voles, Microtus pinetorum, that were disrupted by the replacement of the breeding male and compared them with intact family groups. If reproductive suppression is mediated by chemical cues, then soiled bedding should be sufficient to prevent production of litters by daughters. If reproductive suppression involves a behavioural component, we should observe aggressive behaviours or those indicative of dominance interactions directed from the mother towards the daughter or the replacement male. If replacement of the breeding male leads to conflict between the breeding female and her daughter, then more aggression or dominance interactions would be expected in disrupted than in intact families. The presence of the mother decreased reproduction by daughters, but chemical cues alone were not sufficient to prevent the daughter from mating with the replacement male. Rather, this decrease in reproduction seemed to be mediated by behavioural interactions. We propose that the mother's tugging on the daughter may lead to subordination of the daughter. The mother's presence may also alter the behaviour patterns of the male and daughter, which could delay reproductive activation of the daughter, prevent the formation of pair bonds or inhibit sexual behaviour. These behavioural interactions appear to depend on the presence of an unfamiliar male, because tugging, for example, was less frequent in intact family groups.
