Comparative genomic survey and functional analysis of DKKL1 during spermatogenesis in the Chinese soft-shelled turtle (Pelodiscus sinensis). Int J Biol Macromol 2024; 254:127696. [PMID: 37913874 DOI: 10.1016/j.ijbiomac.2023.127696] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Revised: 09/27/2023] [Accepted: 10/15/2023] [Indexed: 11/03/2023]
Abstract
A feature of the Chinese soft-shelled turtle (Pelodiscus sinensis) is seasonal spermatogenesis; however, the underlying molecular mechanism is not well clarified. Here, we firstly cloned and characterized P. sinensis DKKL1, and then performed comparative genomic studies, expression analysis, and functional validation. P. sinensis DKKL1 had 2 putative N-glycosylation sites and 16 phosphorylation sites. DKKL1 also had classic transmembrane structures that were extracellularly localized. DKKL1's genetic distance was close to turtles, followed by amphibians and mammals, but its genetic distance was far from fishes. DKKL1 genes from different species shared distinct genomic characteristics. Meanwhile, they were also relatively conserved among themselves, at least from the perspective of classes. Notably, the transcription factors associated with spermatogenesis were also identified, containing CTCF, EWSR1, and FOXL2. DKKL1 exhibited sexually dimorphic expression only in adult gonads, which was significantly higher than that in other somatic tissues (P < 0.001), and was barely expressed in embryonic gonads. DKKL1 transcripts showed a strong signal in sperm, while faint signals were detected in other male germ cells. DKKL1 in adult testes progressively increased per month (P < 0.05), displaying a seasonal expression trait. DKKL1 was significantly downregulated in testes cells after the sex hormones (17β-estradiol and 17α-methyltestosterone) and Wnt/β-catenin inhibitor treatment (P < 0.05). Likewise, the Wnt/β-catenin inhibitor treatment dramatically repressed CTCF, EWSR1, and FOXL2 expression. Conversely, they were markedly upregulated after the 17β-estradiol and 17α-methyltestosterone treatment, suggesting that the three transcription factors might bind to different promoter regions, thereby negatively regulating DKKL1 transcription in response to the changes in the estrogen and androgen pathways, and positively controlling DKKL1 transcription in answer to the alterations in the Wnt/β-catenin pathway. Knockdown of DKKL1 significantly reduced the relative expression of HMGB2 and SPATS1 (P < 0.01), suggesting that it may be involved in seasonal spermatogenesis of P. sinensis through a positive regulatory interaction with these two genes. Overall, our findings provide novel insights into the genome evolution and potential functions of seasonal spermatogenesis of P. sinensis DKKL1.

Zhou L, Li M, Wang D. Role of sex steroids in fish sex determination and differentiation as revealed by gene editing. Gen Comp Endocrinol 2021; 313:113893.

Abstract
The involvement of sex steroids in sex determination and differentiation is relatively conserved among non-mammalian vertebrates, especially in fish. Thanks to the advances in genome sequencing and genome editing, significant progresses have been made in the understanding of steroidogenic pathway and hormonal regulation of sex determination and differentiation in fish. It seems that loss of function study of single gene challenges the traditional views that estrogen is required for ovarian differentiation and androgen is needed for testicular development, but it is not so in essence. Steroidogenic enzymes can be classified into two categories based on expression and enzyme activities in fish. One type, encoded by star2, cyp17a1 and cyp19a1a, is involved in estrogen production and exclusively expressed in the gonads. Mutation of these genes results in the up-regulation of male pathway genes and sex reversal from genetic female to male. The other type, encoded by the duplicated paralogs of the above genes, including star1, cyp11a1, cyp17a2 and cyp19a1b, as well as cyp11c1 gene, is dominantly expressed both in gonads and extra-gonadal tissues. Mutation of these genes alters the steroids (androgen, DHP and cortisol) production and spermatogenesis, fertility, secondary sexual characteristics and sexual behavior, but usually does not affect the sex differentiation. For the estrogen receptors (esr1, esr2a and esr2b), single mutation failed to, but double and triple mutation leads to sex reversal from female to male, indicating that at least Esr2a and Esr2b are required to mediate the role of estrogen in sex determination proved by gene editing experiments. Taken together, results from gene editing enrich our understanding of steroid synthesis pathways and further confirm the critical role of estrogen in female sex determination by antagonizing the male pathway in fish.

Relationship between the G protein-coupled oestrogen receptor and spermatogenesis, and its correlation with male infertility. Andrologia 2020; 52:e13779.

Abstract
The aim of this study was to investigate the diagnostic value of serum G protein-coupled oestrogen receptor (GPER) levels and their correlation with semen parameters in men with infertility. The participants were divided into two groups as follows: 76 fertile control men (Group 1) and 77 infertile men (Group 2). Semen analysis, hormonal evaluation, serum GPER level and scrotal ultrasound of the participants were evaluated. Follicle-stimulating hormone and total testosterone levels were not significantly different between the groups (p = .413 and p = .535 respectively). The oestradiol level in Group 1 was significantly lower than that in Group 2 (p < .001). The serum GPER level was found to be significantly higher in Group 1 than that of Group 2 (p < .001). GPER levels were positively correlated with the total sperm count, sperm concentration, motility and morphology in Group 2 (r = 0.303, 0.345, 0.260 and 0.322, respectively, p < .001). In this study, GPER levels were positively correlated with sperm parameters, and it was hypothesised that the decrease in GPER expression might be associated with male infertility by adversely affecting spermatogenesis.

Exogenous oestradiol benzoate induces male mice azoospermia through modulation of oxidative stress and testicular metabolic cooperation. Mol Med Rep 2019; 19:4955-4963.

Abstract
In most cases, exogenous oestradiol benzoate (EB) inhibits spermatogenesis, however, the mechanism underlying this process has not been fully elucidated. The present study investigated the effect of EB on redox equilibrium and glycometabolism in mouse testes. Male Kunming mice were divided into 3 groups and injected with 0, 5 and 10 mg/kg EB, respectively. Histological analysis revealed no sperm and far fewer spermatogenic cells in the testes of EB‑treated mice. Additionally, transmission electron microscopy revealed that mitochondria in Sertoli cells were transformed to vacuoles with irregular cristae in the EB‑treated group. EB also significantly decreased the activities and mRNA expression of catalase, superoxide dismutase, and glutathione peroxidase and increased the activity of nitric oxide synthase and nitric oxide concentration in the testes compared with the control. These results indicated that oxidative damage was caused by EB treatment. With regard to glycometabolism, ATP content and activities of hexokinase and pyruvate kinase were significantly reduced in the EB‑treated group. Although glucose and pyruvate concentrations were significantly increased by EB treatment, levels of lactate, the main energy source of spermatogenic cells, were unchanged. Monocarboxylate transporter 2 (MCT2) and MCT4, which are responsible for lactate transportation, were downregulated by EB. In conclusion, the results of the present study indicated that azoospermia induced by EB in male mice was associated with oxidative damage and the disorder of testicular metabolic cooperation.

Abstract
During goat follicular development, abnormal expression of peroxisome proliferator- activated receptor gamma coactivator-1 alpha (PGC-1α) in granulosa cells (GCs) may contribute to follicular atresia with unknown regulatory mechanisms. In this study, we investigate the effect of ectopic expression or interference of PGC-1α on cell apoptosis of goat first passage granulosa cells (FGCs) in vitro. The results indicate that PGC-1α silencing by short hairpin RNA (shRNA) in goat FGCs significantly reduced mitochondrial DNA (mtDNA) copy number (P < 0.05), changed mitochondria ultrastructure, and induced cell apoptosis (P < 0.05). The transcription and translation levels of the apoptosis-related genes BCL-2-associated X protein (BAX), caspase 3, and caspase 9 were significantly up-regulated (P < 0.05, respectively). Moreover, the ratio of BAX/B-cell lymphoma 2 (BCL-2) was reduced (P < 0.05), and the release of cytochrome c (cyt c) and lactate dehydrogenase (LDH) was significantly enhanced (P < 0.05, respectively) in PGC-1α interference goat FGCs. Furthermore, the expression of anti-oxidative related genes superoxide dismutase 2 (SOD2), glutathione peroxidase (GPx) and catalase (CAT) was down-regulated (P < 0.05, respectively) and the activity of glutathione/glutathione disulfide (GSH/GSSG) was inhibited (P < 0.05). While enforced expression of PGC-1α increased the levels of genes involved in the regulation of mitochondrial function and biogenesis, and enhanced the anti-oxidative and anti-apoptosis capacity. Taken together, our results reveal that lack of PGC-1α may lead to mitochondrial dysfunction and disrupt the cellular redox balance, thus resulting in goat GCs apoptosis through the mitochondria-dependent apoptotic pathway.
