Abstract
In viviparous fish, a considerable degree of variation in placental structures have been described. However, no distinct structures are reported in Scorpaenidae. In this study, we demonstrate a new type of folliculogenesis and follicular placentation in Sebastes schlegelii. Before copulation, the germinal epithelium gradually surrounds the oocytes and develops into individually follicles with a stalk-like structure hanging on the ovigerous lamella, which ensures each follicle have access to spermatozoa after copulation. From V to early gestation stage, the cyp17-I highly expressesaccompanied by cyp19a1a signals disappearance, and 11-ketotestosterone level keeps rising and peaks at blastula stage, while 17β-estradiol declines to the bottom. Meanwhile, the theca cells rapidly proliferate and invade outwards forming a highly hypertrophied and folded microvillous placenta. This unbalance of hormone might be an important factor driving the theca cells proliferation and invasion. Additionally, some conserved genes related to mammalian placentation are significantly high expression in follicular placenta suggesting the high convergence in vertebrate placenta evolution.

Abstract
Leiocassis longirostris is a commercially important fish species that shows a sexually dimorphic growth pattern. A lack of molecular data from the gonads of this species has hindered research and selective breeding efforts. In this study, we conducted a comprehensive analysis of the expression profile of miRNA and mRNA to explore their regulatory roles in the gonadal maturation stage of L. longirostris. We identified 60 differentially expressed miRNAs and 20,752 differentially expressed genes by sequencing. A total of 90 miRNAs and 21 target genes involved in gonad development and sex determination were identified. Overall, the results of this study enhance our understanding of the molecular mechanisms underlying sex determination and differentiation and provide valuable genomic information for the selective breeding of L. longirostris.

Deep Transcriptomic Analysis of Black Rockfish (Sebastes schlegelii) Provides New Insights on Responses to Acute Temperature Stress. Sci Rep 2018; 8:9113. [PMID: 29904092 PMCID: PMC6002380 DOI: 10.1038/s41598-018-27013-z] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2017] [Accepted: 03/27/2018] [Indexed: 12/19/2022] Open
Abstract
In the present study, we conducted an RNA-Seq analysis to characterize the genes and pathways involved in acute thermal and cold stress responses in the liver of black rockfish, a viviparous teleost that has the ability to cope with a wide range of temperature changes. A total of 584 annotated differentially expressed genes (DEGs) were identified in all three comparisons (HT vs NT, HT vs LT and LT vs NT). Based on an enrichment analysis, DEGs with a potential role in stress accommodation were classified into several categories, including protein folding, metabolism, immune response, signal transduction, molecule transport, membrane, and cell proliferation/apoptosis. Considering that thermal stress has a greater effect than cold stress in black rockfish, 24 shared DEGs in the intersection of the HT vs LT and HT vs NT groups were enriched in 2 oxidation-related gene ontology (GO) terms. Nine important heat-stress-reducing pathways were significantly identified and classified into 3 classes: immune and infectious diseases, organismal immune system and endocrine system. Eight DEGs (early growth response protein 1, bile salt export pump, abcb11, hsp70a, rtp3, 1,25-dihydroxyvitamin d(3) 24-hydroxylase, apoa4, transcription factor jun-b-like and an uncharacterized gene) were observed among all three comparisons, strongly implying their potentially important roles in temperature stress responses.

Molecular mechanism of endocrine system impairment by 17α-methyltestosterone in gynogenic Pengze crucian carp offspring. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2016; 128:143-152.

Abstract
The effects of synthetic androgen 17α-methyltestosterone (MT) on endocrine impairment were examined in crucian carp. Immature 7-month old mono-female Pengze crucian carp (Pcc) F2 offspring were exposed to 50 and 100 μg/L of MT (week 2, 4, and 8). Gonadosomatic index, hepatosomatic index and intestine weight altered considerably and oocyte development was repressed. In the treatment groups, ovarian 11-ketotestosterone decreased, whereas 17β-estradiol and testosterone increased, and ovarian aromatase activities increased at week 4. However, in the brain tissue, those values significantly decreased. Quantitative RT-PCR analysis demonstrated changes in steroid receptor genes and upregulation of steroidogenic genes (Pcc-3bhsd, Pcc-11bhsd2 Pcc-cyp11a1), while the other three steroidogenic genes (Pcc-cyp17a1, Pcc-cyp19a1a and Pcc-star) decreased from week 4 to week 8. Ovarian, hepatic Pcc-vtg B and vitellogenin concentration increased in both 50 and 100 μg/L of MT exposure groups. This study adds further information regarding the effects of androgens on the development of previtellogenic oocytes, which suggests that MT could directly target estrogen signaling pathway, or indirectly affect steroidogenesis and vitellogenesis.

Abstract
Steroid hormones are involved in the regulation of a variety of processes like embryonic development, sex differentiation, metabolism, immune responses, circadian rhythms, stress response, and reproduction in vertebrates. Teleost fishes and humans show a remarkable conservation in many developmental and physiological aspects, including the endocrine system in general and the steroid hormone related processes in particular. This review provides an overview of the current knowledge about steroid hormone biosynthesis and the steroid hormone receptors in teleost fishes and compares the findings to the human system. The impact of the duplicated genome in teleost fishes on steroid hormone biosynthesis and perception is addressed. Additionally, important processes in fish physiology regulated by steroid hormones, which are most dissimilar to humans, are described. We also give a short overview on the influence of anthropogenic endocrine disrupting compounds on steroid hormone signaling and the resulting adverse physiological effects for teleost fishes. By this approach, we show that the steroidogenesis, hormone receptors, and function of the steroid hormones are reasonably well understood when summarizing the available data of all teleost species analyzed to date. However, on the level of a single species or a certain fish-specific aspect of physiology, further research is needed.

Gen Comp Endocrinol 2015; 221:134-43. [PMID: 25701739 DOI: 10.1016/j.ygcen.2015.01.026] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2014] [Revised: 01/19/2015] [Accepted: 01/31/2015] [Indexed: 11/27/2022]
Abstract
Estradiol-17β (E2) and maturation-inducing hormone (MIH) are two steroid hormones produced in the teleost ovary that are required for vitellogenic growth and final oocyte maturation and ovulation. During this transition, the main steroid hormone produced in the ovary shifts from estrogens to progestogens. In the commercially important Japanese eel (Anguilla japonica), the MIH 17α,20β-dihydroxy-4-pregnen-3-one (DHP) is generated from its precursor by P450c17, which has both 17α-hydroxylase and C17-20 lyase activities. In order to elucidate the regulatory mechanism underlying the steroidogenic shift from E2 to DHP and the mechanistic basis for the failure of this shift in artificially matured eels, the cDNA for cyp17a2-which encodes P450c17-II-was isolated from the ovary of wild, mature Japanese eel and characterized, and the expression patterns of cyp17a1 and cyp17a2 during induced ovarian development were investigated in cultured eel ovaries. Five cDNAs (types I-V) encoding P450c17-II were identified that had minor sequence variations. HEK293T cells transfected with all but type II P450c17-II converted exogenous progesterone to 17α-hydroxyprogesterone (17α-P), providing evidence for 17α-hydroxylase activity; however, a failure to convert 17α-P to androstenedione indicated that C17-20 lyase activity was absent. Cyp17a2 mRNA was expressed mainly in the head kidney, ovary, and testis, and quantitative PCR analysis demonstrated that expression in the ovary increased during induced vitellogenesis and oocyte maturation/ovulation. In contrast, P450c17-I showed both 17α-hydroxylase and C17-20 lyase activities, and cyp17a1 expression increased until the mid-vitellogenic stage and remained high thereafter. Considering the high level of cyp17a2 transcript in the eel ovary at the migratory nucleus stage together with our previous report demonstrating that eel ovaries have strong 17α-P-to-DHP conversion activity, the failure of artificially maturing eels to produce the maturation-inducing DHP may be explained by a deficiency in 17α-P production due to the persistence of cyp17a1 expression after the completion of vitellogenesis.
