THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 861:160594. [PMID: 36455722 DOI: 10.1016/j.scitotenv.2022.160594] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 11/15/2022] [Accepted: 11/26/2022] [Indexed: 06/17/2023]
Abstract
The synthetic estrogen 17α-ethinylestradiol (EE2) is a common component of hormone therapy and oral contraceptives and has been widely used for nearly 60 years. Numerous studies have shown that exposure to EE2 can affect embryonic development in a number of fish species. The effects of parental and embryonic EE2 exposure on embryo developmental toxicity and the underlying molecular mechanisms, however, have rarely been examined. In this study, embryos collected from parental EE2-exposed adult fish were examined to assess EE2-induecd toxicity during embryo development. The rate of embryo development including heart rate, hatching rate, and larval locomotion were measured to assess embryo developmental toxicity. The embryonic transcriptome was used to delineate the related developmental toxicity pathways. Our results suggest that parental and embryonic EE2 exposure resulted in growth retardation including a reduction in embryo heart rate, a delay in the appearance eye pigmentation, decreased hatching rate and impaired larval locomotion. In addition, gene ontology (GO) enrichment analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, and Ingenuity Pathway Analysis (IPA) of transcriptome revealed that these impairments are controlled by estrogen receptor and related to eye structure, neuronal and synaptic structure, and behaviour. The key factors identified, including PRKAA2, APOB, EPHB2, OXTR, NR2E3, and POU4F2, could serve as biomarkers for assessing EE2-induced embryo developmental toxicity. For the first time, our results show that eye pigmentation is a potentially sensitive marker of EE2-induced embryo developmental toxicity.

Genome-Wide Association Study Identifies Genomic Loci of Sex Determination and Gonadosomatic Index Traits in Large Yellow Croaker (Larimichthys crocea). MARINE BIOTECHNOLOGY (NEW YORK, N.Y.) 2021; 23:127-139.

Abstract
Larimichthys crocea is one of the traditional marine culture fishes in China, widely distributed in South China Sea, East Sea, and southern Yellow Sea. Sex dimorphism is evident in this species that females present a substantial growth strength than males, suggesting breeding females could obtain more economic benefits in L. crocea aquaculture industry. With the continuous expansion of aquaculture industry, both identifying sex-associated genome region and understanding the genetic basis underlying gonad differentiation and development matter to not only sex control aquaculture but also breeding industry. Thus, genome-wide association analysis (GWAS) of sex determination was conducted with a random breeding population of 905 individuals (including 463 females and 442 males) by ddRAD sequencing. For sex determination, 21 significant single nucleotide polymorphisms (SNPs) in chromosome (Chr) 22 were identified. Surrounding these SNPs, we founded 14 candidate genes, including dmrt1, dmrt3, and piwil2, fam102a, and odf2. The sex-associated region was narrowed down further to 2.4 Mb on Chr22 through Fst scanning and insertion-deletion (InDel) analysis. Besides, 3 SNPs in the supposed sex-determining region on Chr22 were identified as highly associated with gonad differentiation through GWAS on gonadosomatic index (GSI) in 350 males and 231 females. Because of the significant difference of GSI between females and males of L. crocea, GWAS on GSI of different genders was also conducted independently. Finally, we identified a SNP in Chr18 showing genome-wide significant association with male GSI (MGSI) and three genes axl, cyp2a10, and cyp2g1 involved in the gonadal development regulation process of aromatase. Overall, this study explored the genetic basis of sex determination mechanism and provided novel insights into gonad differentiation and development, offering solid genetic support for sex control breeding, marker-assisted selection, and marine resources conservation.

Abstract
In this study, three nanos gene subtypes (Lcnanos1, Lcnanos2 and Lcnanos3) from Larimichthys crocea, were cloned and characterized. We determined the spatio-temporal expression patterns of each subtype in tissues as well as the cellular localization of mRNA in embryos. Results showed that deduced Nanos proteins have two main homology domains: N-terminal CCR4/NOT1 deadenylase interaction domain and highly conserved carboxy-terminal region bearing two conserved CCHC zinc-finger motifs. The expression levels of Lcnanos1 in testis were significantly higher than other tissues, followed by heart, brain, eye, and ovary. Nevertheless, both Lcnanos2 and Lcnanos3 were restrictedly expressed in testis and ovary, respectively. No signals of Lcnanos1 and Lcnanos2 expression were detected at any developmental stages during embryogenesis. On the contrary, the signals of Lcnanos3 were detected in all stages examined. Lcnanos3 transcripts were firstly localized to the distal end of cleavage furrow at the 2-cell stage. Subsequently, mounting positive signals started to appear in a small number of cells as the embryo developed to blastula stage and early-gastrula stage. As development proceeded, positive signals were found in the primitive gonadal ridge. These cells of Lcnanos3 positive signals implied the specification of the future PGCs at this stage. It also suggested that PGCs of croaker originate from four clusters of cells which inherit maternal germ plasm at blastula stage. Furthermore, we preliminarily analyzed the migration route of PGCs in embryos of L. crocea. In short, this study laid the foundation for studies on specification and development of germ cell from L. crocea during embryogenesis.

Abstract
Both systemic and locally released steroid hormones, such as cortisol and estrogens, show immunomodulatory actions. This research gives evidence that circulating and leukocyte-derived estrogens can be involved in the regulation of the immune response in common carp, during homeostasis and upon restraining stress. It was found that stress reduced level of blood 17β-estradiol (E2) and down-regulated the gene expression of components of the "classical" estrogen system: the nuclear estrogen receptors and the aromatase CYP19, in the hypothalamus, the pituitary and in the ovaries. In contrast, higher gene expression of the nuclear estrogen receptors and cyp19a was found in the head kidney of stressed animals. Moreover, stress induced changes in the E2 level and in the estrogen sensitivity at local/leukocyte level. For the first time in fish, we showed the presence of physiologically relevant amounts of E2 and the substrates for its conversion (estrone - E1 and testosterone - T) in head kidney monocytes/macrophages and found that its production is modulated upon stress. Moreover, stress reduced the sensitivity of leukocytes towards estrogens, by down-regulation the expression of the erb and cyp19 genes in carp phagocytes. In contrast, era expression was up-regulated in the head kidney monocytes/macrophages and in PBLs derived from stressed animals. We hypothesize that, the increased expression of ERα, that was observed during stress, can be important for the regulation of leukocyte differentiation, maturation and migration. In conclusion, these results indicate that, in fish, the estrogen network can be actively involved in the regulation of the systemic and local stress response and the immune response.

Abstract
Aquaculture industry in the Mediterranean region exhibits a growing interest for the Mediterranean meager Argyrosomus regius. Some preliminary works showed a good growth performance of the species in nearly isosmotic salinities. However, the patterns of alteration of prolactin (Prl) as well as growth hormone (Gh)/insulin growth factor-1 (Igf1) axis at the molecular level are not yet described in this species. Therefore, we cloned and sequenced partial cDNAs for pituitary prolactin (prl) and growth hormone (gh), hepatic insulin-like growth factor (igf1), and β-actin (actb). Expression patterns of these transcripts were tested in juveniles of A. regius acclimated to four different environmental salinities: (1) 5 ‰ (hyposmotic); (2) 12 ‰ (isosmotic); (3) 38 ‰ (hyperosmotic; seawater control); and (4) 55 ‰ (extremely hyperosmotic). All investigated transcripts shared high sequence identities with their counterparts in other perciformes. prl mRNA levels showed inverse pattern with increasing salinities. gh mRNA enhanced significantly in both 12 and 55 ‰ salinity groups in comparison with the control group, while igf1 showed its maximum expression levels under the nearly isosmotic environment. The results indicated clear sensitivity of prl, gh and igf1 to changes in environmental salinity, which can possibly control the euryhalinity capacity of this species.

Abstract
Estrogens interact with classical intracellular nuclear receptors (ESR), and with G-coupled membrane receptors (GPER). In the eel, we identified three nuclear (ESR1, ESR2a, ESR2b) and two membrane (GPERa, GPERb) estrogen receptors. Duplicated ESR2 and GPER were also retrieved in most extant teleosts. Phylogeny and synteny analyses suggest that they result from teleost whole genome duplication (3R). In contrast to conserved 3R-duplicated ESR2 and GPER, one of 3R-duplicated ESR1 has been lost shortly after teleost emergence. Quantitative PCRs revealed that the five receptors are all widely expressed in the eel, but with differential patterns of tissue expression and regulation. ESR1 only is consistently up-regulated in vivo in female eel BPG-liver axis during induced sexual maturation, and also up-regulated in vitro by estradiol in eel hepatocyte primary cultures. This first comparative study of the five teleost estradiol receptors provides bases for future investigations on differential roles that may have contributed to the conservation of multiple estrogen receptors.
