“…There is evidence that estrogen is biologically relevant in male invertebrates (e.g. clams Tapes philippinarum ; Negrato et al ., ; earwigs Euborellia annulipes ; Rankin & Grosjean, ). Parasites infecting G. pseudolimnaeus may be manipulating estrogen levels, similar to how tapeworms feminize male mice (Larralde et al ., ) or the amphipods may be increasing estrogen levels to combat infection, as estrogen often decreases susceptibility to parasites (Bilbo & Nelson, ; Klein, ).…”

Correlations between estrogen and testosterone concentrations, pairing status and acanthocephalan infection in an amphipod

Mechanisms by which parasites induce phenotypic alterations are poorly understood in many host-parasite systems. Amphipods are an intermediate host for a range of acanthocephalan parasites, and there is substantial evidence that parasites manipulate the physiology and behavior of amphipods in a variety of ways, including significant reproductive impacts. Evidence suggests such manipulations may result from disruption of serotonergic and dopaminergic pathways. However, correlations with other hormones have not been widely investigated, in part because we lack understanding of the production and action of hormones such as estrogen and testosterone in amphipods. We investigated how estrogen (17b-estradiol) and testosterone concentrations vary between unparasitized male and female amphipods Gammarus pseudolimnaeus that were and were not in precopulatory pairs. We also investigated whether infection with the acanthocephalan Corynosoma sp. is correlated with differences in estrogen or testosterone concentrations when compared to unparasitized conspecifics. Our results indicate that estrogen and testosterone differ significantly between male and female amphipods, whether paired or unpaired, suggesting they may have sex-specific functions. The biological relevance of these hormones merits increased attention in light of the prevalence of endocrine-disrupting compounds in aquatic systems. Further, we found that encysted acanthocephalan parasites are correlated with elevated concentrations of estrogen and depressed concentrations of testosterone in male, but not female amphipods. This correlation suggests the need for a broader investigation of the mechanisms underlying phenotypic alterations of amphipod behavior and physiology by acanthocephalan parasites.

“…Prepubertal rats exposed to BPA exhibit suppressed ovarian development, with reduced expression of the follicle development-related genes Figla and H1foo and increased expression of the anti-Müllerian hormone (AMH) [ 222 ]. Exposure to BPA in drinking water results in the inhibition of ovarian growth in Euborellia annulipes [ 223 ]. Exposure to BPA, BPS, and BPAF delays oocyte maturation in earthworm and zebrafish ovaries [ 224 , 225 ].…”

Reproductive disorders are considered a global health problem influenced by physiological, genetic, environmental, and lifestyle factors. The increased exposure to bisphenols, a chemical used in large quantities for the production of polycarbonate plastics, has raised concerns regarding health risks in humans, particularly their endocrine-disrupting effects on female reproductive health. To provide a basis for future research on environmental interference and reproductive health, we reviewed relevant studies on the exposure patterns and levels of bisphenols in environmental matrices and humans (including susceptible populations such as pregnant women and children). In addition, we focused on in vivo, in vitro, and epidemiological studies evaluating the effects of bisphenols on the female reproductive system (the uterus, ovaries, fallopian tubes, and vagina). The results indicate that bisphenols cause structural and functional damage to the female reproductive system by interfering with hormones; activating receptors; inducing oxidative stress, DNA damage, and carcinogenesis; and triggering epigenetic changes, with the damaging effects being intergenerational. Epidemiological studies support the association between bisphenols and diseases such as cancer of the female reproductive system, reproductive dysfunction, and miscarriage, which may negatively affect the establishment and maintenance of pregnancy. Altogether, this review provides a reference for assessing the adverse effects of bisphenols on female reproductive health.

Bisphenol-A affects the developmental progression and expression of heat-shock protein genes in the moth Sesamia nonagrioides

The effects of bisphenol A (BPA) on the endocrine system of vertebrates have been demonstrated in several studies. Here, we report the impact of BPA on the developmental progression and expression of heat shock protein genes on the terrestrial insect Sesamia nonagrioides (Lepidoptera: Noctuidae). S. nonagrioides 1st instar larvae were exposed until the end of 6th (last) instar to selected concentrations of BPA (1 μg/L, 10 μg/L, 100 μg/L, 1 mg/L and 10 mg/L) applied in their artificial diets. The lower doses of BPA (1-10 μg/L) were found to decrease larvae's weight while the 100 μg/L dose increased it. The higher doses of BPA were found to induce various abnormal phenotypes during 5th instar larval molting, larval-pupal transformation and metamorphosis. The developmental and metamorphosis endpoints presented here may indicate the possible impact of BPA on terrestrial insects. Additionally, 6th instar larvae were injected with several concentrations of BPA. Semi-quantitative and Real-Time PCR assays were used to identify the effects of BPA in the transcriptional regulation of five heat shock protein genes (SnoHsp19.5, SnoHsp20.8, SnoHsp70, SnoHsc70 and SnoHsp83). Application of BPA by feeding or by injection induced the synthesis of the SnoHsp19.5 and SnoHsp20.8 mRNAs. The expression levels of SnoHsp70 were not affected. In contrast, SnoHsc70 and SnoHsp83, which play a pivotal role in vertebrate sex steroid signal transduction, were elevated by BPA. Our results suggest that SnoHsp19.5, SnoHsp20.8, SnoHsp83 and SnoHsc70 genes can be modulated by BPA.
