King AC, Zenker AK. Sex blind: bridging the gap between drug exposure and sex-related gene expression in Danio rerio using next-generation sequencing (NGS) data and a literature review to find the missing links in pharmaceutical and environmental toxicology studies. FRONTIERS IN TOXICOLOGY 2023; 5:1187302. [PMID: 37398910 PMCID: PMC10312089 DOI: 10.3389/ftox.2023.1187302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Accepted: 06/01/2023] [Indexed: 07/04/2023] Open
Abstract
The sex of both humans and Danio rerio has previously been shown to affect the way individuals respond to drug exposure. Genes which allow identification of sex in juvenile zebrafish show potential to reveal these confounding variables between sex in toxicological and preclinical trials but the link between these is so far missing. These sex-specific, early expressed genes where expression is not altered by drug exposure must be carefully selected for this purpose. We aimed to discover genes which can be used in pharmaceutical trials and environmental toxicology studies to uncover sex-related variations in gene expression with drug application using the model organism Danio rerio. Previously published early sex determining genes from King et al. were evaluated as well as additional genes selected from our zebrafish Next-generation sequencing (NGS) data which are known from previously published works not to be susceptible to changes in expression with drug exposure. NGS revealed a further ten female-specific genes (vtg1, cyp17a1, cyp19a1a, igf3, ftz-f1, gdf9, foxl2a, Nr0b1, ipo4, lhcgr) and five male related candidate genes (FKBP5, apobb1, hbaa1, dmrt1, spata6) which are also expressed in juvenile zebrafish, 28 days post fertilisation (dpf). Following this, a literature review was performed to classify which of these early-expressed sex specific genes are already known to be affected by drug exposure in order to determine candidate genes to be used in pharmaceutical trials or environmental toxicology testing studies. Discovery of these early sex-determining genes in Danio rerio will allow identification of sex-related responses to drug testing to improve sex-specific healthcare and the medical treatment of human patients.

Li X, Miao C, Wang L, Liu M, Chang H, Tian B, Wang D. Estrogen promotes Epithelial ovarian cancer cells proliferation via down-regulating expression and activating phosphorylation of PTEN. Arch Biochem Biophys 2023:109662. [PMID: 37276925 DOI: 10.1016/j.abb.2023.109662] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 05/05/2023] [Accepted: 06/02/2023] [Indexed: 06/07/2023]
Abstract
Epithelial ovarian cancer (EOC) is the most common of cancer death among malignant tumors in women, its occurrence and development are strongly linked to estrogen. Having identified the phosphatase and tensin homologue (PTEN) is a potent tumor suppressor regulating cell proliferation, migration, and survival. Meanwhile, there is a correlation between PTEN protein expression and estrogen receptor expression in EOC. However, no study has amplified on the molecular regulatory mechanism and function between estrogen and PTEN in the development of EOC. In this research, we found that PTEN shows a low expression level in EOC tissues and estrogen decreased PTEN expression via the estrogen receptor 1 (ESR1) in EOC cells. Knockdown of PTEN enhanced the proliferation and migration level of EOC cells driven by estrogen. Moreover, PTEN was also phosphorylated by G protein-coupled receptor 30 (GPR30)-Protein kinase C (PKC) signaling pathway upon estrogen stimulation. Inhibiting the phosphorylation of PTEN weakened the proliferation and migration of estrogen induced-EOC cells estrogen and decreased the phosphorylation of Protein kinase B (AKT) and Mammalian target of rapamycin (mTOR). These results indicated that estrogen decreased PTEN expression level via the ESR1 genomic pathway and phosphorylated PTEN via the GPR30-PKC non-genomic pathway to activate the PI3K/AKT/mTOR signaling pathway, thereby determining the fate of EOC cells.

Abstract
Cholangiocarcinoma (CCA) is an aggressive malignancy originating from the epithelium of the bile duct. The prognosis of patients is poor regardless of radical resection and chemoradiotherapy. The current classification and prognostic model of CCA are unable to satisfy the requirements for predicting the clinical outcome and exploring therapeutic targets. Estrogen signaling is involved in diverse cancer types, and it has long been established that CCA could be regulated by estrogen. In our study, estrogen response was identified to be significantly and stably correlated with poor prognosis in CCA. Employing several algorithms, CCA was classified into ES cluster A and B. ES cluster B was mainly composed of patients with fluke infection and overlapped with CCA cluster 1/2, and ES cluster A was mainly composed of patients without fluke infection and overlapped with CCA cluster 3/4. COMT and HSD17B1 were identified to be responsible for the differential estrogen response between ES clusters A and B, and the estrogen response may be correlated with the differentiation and cancer stemness of CCA at the single-cell level. Complement activation and the expression of C3 and C5, which are mainly expressed by CCA cells, were significantly downregulated in ES cluster B. An estrogen response risk score (ESRS) model was constructed to predict the prognosis of CCA, followed by a nomogram integrating ESRS and clinical features. Finally, altered pathways, applicable drugs and sensitivity to chemical drugs were analyzed specific to the estrogen response. In summary, our results provide insights into the role of the estrogen response in CCA progression as well as applicable drugs and potential therapeutic targets in estrogen metabolism, the complement system and ESRS-related pathways.

Effects of Sex Steroid Receptor Agonists and Antagonists on the Expression of the FOXL2 Transcription Factor and its Target Genes AMH and CYP19A1 in the Neonatal Porcine Ovary. ANNALS OF ANIMAL SCIENCE 2022.

Abstract
Abstract
Recently, we have demonstrated that neonatal exposure to androgen and estrogen agonists or antagonists influenced the number of ovarian follicles in piglets. Since the FOXL2 transcription factor is required for proper ovarian follicle formation and activation, the objective of the study was to examine effects of exposure of the neonatal porcine ovary to testosterone propionate (TP; an androgen), flutamide (FLU; an antiandrogen), 4-tert-octylphenol (OP; compound with estrogenic activity), ICI 182,780 (ICI; an antiestrogen), and methoxychlor (MXC; compound with estrogenic, antiestrogenic and antiandrogenic properties) on FOXL2 expression and expression of its target genes, AMH and CYP19A1. Piglets were injected subcutaneously with TP, FLU, OP, ICI, MXC, or corn oil (control) between postnatal days 1 and 10 (n = 4/each group). Ovaries were excised from the 11-day-old piglets and the expression of FOXL2, AMH and CYP19A1 was examined using immunohistochemistry and/or real-time PCR and Western blot. FOXL2 was localized in stroma cells surrounding egg nests and in granulosa cells. TP, OP and MXC increased both FOXL2 and AMH mRNAs, while FLU and ICI decreased CYP19A1 mRNA. The increased FOXL2 protein abundance was found in all examined groups. In addition, TP, OP, ICI and MXC increased AMH protein abundance, while TP, FLU and OP decreased CYP19A1 protein abundance. In conclusion, neonatal exposure to sex steroid receptor agonists and antagonists increased FOXL2 expression at mRNA and/or protein levels and affected FOXL2 target genes in the ovaries of 11-day-old piglets. Therefore, it seems that impaired ovarian folliculogenesis induced by altered steroid milieu during the neonatal development period in pigs may, at least in part, involve FOXL2.

Estrogen Receptors-Mediated Apoptosis in Hormone-Dependent Cancers. Int J Mol Sci 2022; 23:ijms23031242.

Abstract
It is known that estrogen stimulates growth and inhibits apoptosis through estrogen receptor(ER)-mediated mechanisms in many cancer cell types. Interestingly, there is strong evidence that estrogens can also induce apoptosis, activating different ER isoforms in cancer cells. It has been observed that E2/ERα complex activates multiple pathways involved in both cell cycle progression and apoptotic cascade prevention, while E2/ERβ complex in many cases directs the cells to apoptosis. However, the exact mechanism of estrogen-induced tumor regression is not completely known. Nevertheless, ERs expression levels of specific splice variants and their cellular localization differentially affect outcome of estrogen-dependent tumors. The goal of this review is to provide a general overview of current knowledge on ERs-mediated apoptosis that occurs in main hormone dependent-cancers. Understanding the molecular mechanisms underlying the induction of ER-mediated cell death will be useful for the development of specific ligands capable of triggering apoptosis to counteract estrogen-dependent tumor growth.

Abstract
Epithelial ovarian cancer (EOC) is the most lethal estrogen-sensitive gynecological cancer. Studies have reported that estrogen induces rapid cellular calcium mobilization in cells and can determine the fate of a cell. We found that estrogen increased the calcium release-activated calcium channel modulator 1 (Orai1) protein expression levels in SK-OV-3 cells. However, to date, there has been no research on the functional relationship and molecular mechanism of estrogen-regulating Orai1 during EOC development. In our study, Orai1 had a high expression level in high-grade serous ovarian tumor tissues and SK-OV-3 cells. Estrogen promoted cell proliferation and migration while inhibiting cell apoptosis in SK-OV-3 cells. Orai1 silencing suppressed estrogen-induced cell migration and proliferation. Overexpression of Orai1, however, enhanced the ability of 17β-estradiol (E2) to exert its function. Estrogen induced rapid calcium influx in SK-OV-3 cells. Knockdown of Orai1 in SK-OV-3 cells blocked E2-induced stored-operated Ca2+ influx. The messenger RNA expression of caspase 3, matrix metallopeptidase 1, and cyclin-dependent kinase 6 were regulated via Orai1 under E2 treatment. Our results suggest that estrogen, by regulating Orai1, induced calcium influx to determine cell fate.

Abstract
Estrogen can elicit pleiotropic cellular responses via a diversity of estrogen receptors (ERs)-mediated genomic and rapid non-genomic mechanisms. Unlike the genomic responses, where the classical nuclear ERα and ERβ act as transcriptional factors following estrogen binding to regulate gene transcription in estrogen target tissues, the non-genomic cellular responses to estrogen are believed to start at the plasma membrane, leading to rapid activation of second messengers-triggered cytoplasmic signal transduction cascades. The recently acknowledged ER, GPR30 or GPER, was discovered in human breast cancer cells two decades ago and subsequently in many other cells. Since its discovery, it has been claimed that estrogen, ER antagonist fulvestrant, as well as some estrogenic compounds can directly bind to GPER, and therefore initiate the non-genomic cellular responses. Various recently developed genetic tools as well as chemical ligands greatly facilitated research aimed at determining the physiological roles of GPER in different tissues. However, there is still lack of evidence that GPER plays a significant role in mediating endogenous estrogen action in vivo. This review summarizes current knowledge about GPER, including its tissue expression and cellular localization, with emphasis on the research findings elucidating its role in health and disease. Understanding the role of GPER in estrogen signaling will provide opportunities for the development of new therapeutic strategies to strengthen the benefits of estrogen while limiting the potential side effects.
