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.

Dkk3/REIC Deficiency Impairs Spermiation, Sperm Fibrous Sheath Integrity and the Sperm Motility of Mice. Genes (Basel) 2022; 13:genes13020285. [PMID: 35205329 PMCID: PMC8872165 DOI: 10.3390/genes13020285] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Revised: 01/28/2022] [Accepted: 01/29/2022] [Indexed: 02/06/2023] Open
Abstract
The role of Dickkopf-3 (Dkk3)/REIC (The Reduced Expression in Immortalized Cells), a Wnt-signaling inhibitor, in male reproductive physiology remains unknown thus far. To explore the functional details of Dkk3/REIC in the male reproductive process, we studied the Dkk3/REIC knock-out (KO) mouse model. By examining testicular sections and investigating the sperm characteristics (count, vitality and motility) and ultrastructure, we compared the reproductive features between Dkk3/REIC-KO and wild-type (WT) male mice. To further explore the underlying molecular mechanism, we performed RNA sequencing (RNA-seq) analysis of testicular tissues. Our results showed that spermiation failure existed in seminiferous tubules of Dkk3/REIC-KO mice, and sperm from Dkk3/REIC-KO mice exhibited inferior motility (44.09 ± 8.12% vs. 23.26 ± 10.02%, p < 0.01). The Ultrastructure examination revealed defects in the sperm fibrous sheath of KO mice. Although the average count of Dkk3/REIC-KO epididymal sperm was less than that of the wild-types (9.30 ± 0.69 vs. 8.27 ± 0.87, ×106), neither the gap (p > 0.05) nor the difference in the sperm vitality rate (72.83 ± 1.55% vs. 72.50 ± 0.71%, p > 0.05) were statistically significant. The RNA-seq and GO (Gene Oncology) enrichment results indicated that the differential genes were significantly enriched in the GO terms of cytoskeleton function, cAMP signaling and calcium ion binding. Collectively, our research demonstrates that Dkk3/REIC is involved in the process of spermiation, fibrous sheath integrity maintenance and sperm motility of mice.

Abstract
Meiosis is a complex process involving the expression and interaction of numerous genes in a series of highly orchestrated molecular events. Fam9b localized in Xp22.3 has been found to be expressed in testes. However, FAM9B expression, localization, and its role in meiosis have not been previously reported. In this study, FAM9B expression was evaluated in the human testes and ovaries by RT-PCR, qPCR, and western blotting. FAM9B was found in the nuclei of primary spermatocytes in testes and specifically localized in the synaptonemal complex (SC) region of spermatocytes. FAM9B was also evident in the follicle cell nuclei and diffusely dispersed in the granular cell cytoplasm. FAM9B was partly co-localized with SYCP3, which is essential for both formation and maintenance of lateral SC elements. In addition, FAM9B had a similar distribution pattern and co-localization as γH2AX, which is a novel biomarker for DNA double-strand breaks during meiosis. All results indicate that FAM9B is a novel meiosis-associated protein that is co-localized with SYCP3 and γH2AX and may play an important role in SC formation and DNA recombination during meiosis. These findings offer a new perspective for understanding the molecular mechanisms involved in meiosis of human gametogenesis.

Abstract
Accumulating evidence has shown that Wnt signaling is deeply involved in male reproductive physiology, and malfunction of the signal path can cause pathological changes in genital organs and sperm cells. These abnormalities are diverse in manifestation and have been constantly found in the knockout models of Wnt studies. Nevertheless, most of the research solely focused on a certain factor in the Wnt pathway, and there are few reports on the overall relation between Wnt signals and male reproductive physiology. In our review, Wnt findings relating to the reproductive system were sought and summarized in terms of Wnt ligands, Wnt receptors, Wnt intracellular signals and Wnt regulators. By sorting out and integrating relevant functions, as well as underlining the controversies among different reports, our review aims to offer an overview of Wnt signaling in male reproductive physiology and pathology for further mechanistic studies.

Abstract
Ran-binding protein 3 (RanBP3) is a Ran-interacting protein, which participates in the Ran GTPase system in cancer cell biology. However, the expression pattern and physiological role of RanBP3 remain largely unknown. In this study, we found that RanBP3 was expressed in human testes and localised to spermatogonium and spermatocyte of germ cells. In subcellular structure, its localisation is in the nucleus and cytoplasm. Interestingly, compared with normal groups, RanBP3 expression was lower in groups of patients with Maturation Arrest (MA) and Sertoli cell-only syndrome (SCO) when considered by the Johnson Score. RanBP3 expression in the MA group and SCO groups was dramatically lower than that in the normal control group. Studies have shown that RanBP3, which is one of the helper factors of Ran, is mainly participate in the nucleocytoplasmic transport of cells. RanBP3 helps Ran to achieve some functions such as nucleocytoplasmic transport, spindle assembly during mitosis and nuclear assembly after mitosis. Consequent changes in the expression of RanBP3 may associate with human spermatogenesis disorders and male infertility. The identification and characterisation of RanBP3 enhances our understanding of the molecular mechanisms underpinning its function in human spermatogenesis and male infertility.

Differential Sperm Motility Mediates the Sex Ratio Drive Shaping Mouse Sex Chromosome Evolution. Curr Biol 2019; 29:3692-3698.e4.

Abstract
The mouse sex chromosomes exhibit an extraordinary level of copy number amplification of postmeiotically expressed genes [1, 2], driven by an “arms race” (genomic conflict) between the X and Y chromosomes over the control of offspring sex ratio. The sex-linked ampliconic transcriptional regulators Slx and Sly [3, 4, 5, 6, 7] have opposing effects on global transcription levels of the sex chromosomes in haploid spermatids via regulation of postmeiotic sex chromatin (PMSC) [8, 9, 10, 11] and opposing effects on offspring sex ratio. Partial deletions of the Y chromosome (Yq) that reduce Sly copy number lead to global overexpression of sex-linked genes in spermatids and either a distorted sex ratio in favor of females (smaller deletions) or sterility (larger deletions) [12, 13, 14, 15, 16]. Despite a large body of work studying the role of the sex chromosomes in regulating spermatogenesis (recent reviews [17, 18, 19, 20]), most studies do not address differential fertility effects on X- and Y-bearing cells. Hence, in this study, we concentrate on identifying physiological differences between X- and Y-bearing sperm from Yq-deleted males that affect their relative fertilizing ability and consequently lead to sex ratio skewing. We show that X- and Y-bearing sperm in these males have differential motility and morphology but are equally able to penetrate the cumulus and fertilize the egg once at the site of fertilization. The altered motility is thus deduced to be the proximate cause of the skew. This represents the first demonstration of a specific difference in sperm function associated with sex ratio skewing. The sex ratio skew in the offspring of Yq-deleted male mice is abolished by IVF In Yqdel males, Y sperm are more severely morphologically distorted than X sperm Similarly, Y sperm in these males have relatively impaired motility This motility difference explains the sex ratio skew in offspring of these males

Abstract
The aim of the present study was to explore the underlying mechanism and diagnostic potential of Ran-binding protein M (RanBPM) in human spermatogenesis and oogenesis. RanBPM expression in human testis and ovaries was analysed using polymerase chain reaction (PCR) and western blotting, and immunofluorescence was performed on testis and ovary tissue sections during different developmental stages of spermatogenesis and oogenesis using RanBPM antibodies. Interactions with a variety of functional proteins were also investigated. RanBPM mRNA and protein expression levels were determined by PCR and western blotting in the tissue sections. Results revealed that the mRNA expression levels were highest in the testis followed by the ovary. The RanBPM protein was predominantly localized in the nucleus of germ cells, and the expression levels were highest in pachytene spermatocytes and cells surrounding spermatids in testis tissue. In ovary cells, RanBPM was localized in the nucleus and cytoplasm. In conclusion, the results suggested that RanBPM may have multiple roles in the regulation of germ cell proliferation during human spermatogenesis and oogenesis. This research may provide a novel insight into the underlying molecular mechanism of RanBPM and may have implications for the clinical diagnosis and treatment of human infertility.

INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY 2017; 10:9427-9435.

Abstract
BACKGROUND The distribution and functional integrity of members of the tripartite motif (TRIM) protein family are essential for cell proliferation, development and apoptosis, and TRIM proteins have been linked to various cancers. To explore the diagnostic potential and mechanisms of TRIM27 in human spermatogenesis and oogenesis, we analyzed its localization pattern and putative roles in human testes and ovaries. METHODS TRIM27 mRNA and protein levels in human testes and ovaries were investigated using RT-PCR and western blotting, respectively. TRIM27 was abundantly transcribed in human testes and ovaries, particularly during the early stages of spermatogenesis, and localized in the nuclei of primary spermatocytes. Immunofluorescence also revealed a diffuse distribution in the cytoplasm of round spermatids, and the protein was abundant in ovary tissue during various stages of oogenesis development. RESULTS TRIM27 mRNA and protein was abundantly transcribed in male and female human germ cells by RT-PCR and western blotting in the human testes followed by the ovary. Immunohistochemical results revealed TRIM27 protein was abundant in the sex body of primary spermatocytes undergoing meiotic prophase during the first cycle of spermatogenesis. Moreover, Trim27 was diffusely localized in the cytoplasm of spermatids and round spermatids. Furthermore, TRIM27 was localized to both the nucleus and cytoplasm of human ovary cells. CONCLUSIONS TRIM27 as a gametogenesis-related protein could play multiple roles in the regulation of sex body formation and germ cell proliferation during spermatogenesis and oogenesis. The identification and characterization of TRIM27 enhances our understanding of the molecular mechanisms underpinning its functions, and provides insight into its potential role in the pathogenesis of germ cell differentiation and infertility.

Abstract
ABSTARCT Formation of the XY body is believed to prevent recombination between X and Y chromosomes during meiosis. We recently demonstrated that SYCP3-like X-linked 2 (Slx2) could be involved in synaptonemal complex formation as well as XY body maintenance during meiosis. In order to further investigate the role and composition of XY body protein complexes in meiotic processes and spermatogenesis, a yeast 2-hybrid screening was performed, and the tripartite motif protein 27(Trim27) was found to interact with Slx2 and co-localized in the XY body. Trim27 has a tripartite motif (TRIM) consisting of a RING finger, B-box and coiled-coil domains, and is a transcriptional regulator that is expressed in various tumor cell lines. In this study, we showed that Slx2 and Trim27 were highly expressed in meiosis of mouse testis. And the Slx2/Trim27 interaction was confirmed in vivo by co-immunoprecipitation and mammalian 2-hybrid interaction assays. Moreover, cytoimmuno localization experiments revealed that Slx2/Trim27 was co-localized to the XY body of spermatocytes during meiosis, and immunohistochemical results revealed co-localization of Trim27 and γ-H2AX in the XY body of primary spermatocytes in the mouse testis. Trim27 may therefore be a transcriptional regulation protein connecting Slx2 and γ-H2AX, thereby promoting the formation of a more potent XY body protein complex in meiotic processes and spermatogenesis. In conclusion, Trim27 connecting Slx2 may regulate meiotic processes in multiple ways by influencing XY body formation and germ cell proliferation during spermatogenesis.

Abstract
Mammalian spermatogenesis is a highly regulated multistage process of sperm generation. It is hard to uncover the real function of a testis specific gene in vitro since the in vitro model is not yet mature. With the development of the CRISPR/Cas9 (Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR-associated 9) system, we can now rapidly generate knockout mouse models of testis specific genes to study the process of spermatogenesis in vivo. SYCP3-like X-linked 2 (SLX2) is a germ cell specific component, which contains a Cor1 domain and belongs to the XLR (X-linked, lymphocyte regulated) family. Previous studies suggested that SLX2 might play an important role in mouse spermatogenesis based on its subcellular localization and interacting proteins. However, the function of SLX2 in vivo is still elusive. Here, to investigate the functions of SLX2 in spermatogenesis, we disrupted the Slx2 gene by using the CRISPR/Cas9 system. Since Slx2 is a testis specific X-linked gene, we obtained knockout male mice in the first generation and accelerated the study process. Compared with wild-type mice, Slx2 knockout mice have normal testis and epididymis. Histological observation of testes sections showed that Slx2 knockout affected none of the three main stages of spermatogenesis: mitosis, meiosis and spermiogenesis. In addition, we further confirmed that disruption of Slx2 did not affect the number of spermatogonial stem cells, meiosis progression or XY body formation by immunofluorescence analysis. As spermatogenesis was normal in Slx2 knockout mice, these mice were fertile. Taken together, we showed that Slx2 itself is not an essential gene for mouse spermatogenesis and CRISPR/Cas9 technique could speed up the functional study of testis specific X-linked gene in vivo.

Abstract
Background Spermatogenesis is the complex process by which diploid stem cells generate haploid germ cells in gamete production. Members of the Xlr (X-chromosome linked, lymphocyte regulated) superfamily play essential roles in spermatogenesis. The expression, localization and role in spermatogenesis of one such member, Xlr5c, has not been reported previously. Methodology/Principal Findings Xlr5c mRNA and protein levels in murine testes and other tissues were investigated using RT-PCR and Western blotting. Xlr5c was abundantly transcribed in mouse testes, particularly during the early stages of spermatogenesis and throughout prophase I in the nuclei of spermatocytes. Xlr5c was specifically localized at synaptonemal complexes(SCs) region in preleptotene and pachytene spermatocytes, as was the homologous Xlr protein Sycp3. Conclusions/Significance These results suggest that Xlr5c was abundantly transcribed in germ cells, localized at SCs region, where it may play a potential role during the early stages of spermatogenesis. Identification and characterization of this novel testis protein may offer a new perspective for understanding of the molecular mechanisms involved in germ cell differentiation.

Abstract
Gametogenesis is a complex biological process of producing cells for sexual reproduction. Xlr super family members containing a conserved COR1 domain play essential roles in gametogenesis. In the present study, we identified that Slx2, a novel member of Xlr super family, is specifically expressed in the meiotic oocytes, which is demonstrated by western blotting and immunohistochemistry studies. In the first meiotic prophase, SLX2 is unevenly distributed in the nuclei of oocytes, during which phase SLX2 is partly co-localized with SYCP3 in synaptonemal complex and γH2AX in the nucleus of oocytes. Interestingly, the localization of SLX2 was found to be switched into the cytoplasm of oocytes after prometaphase I during oocyte maturation. Furthermore, yeast two-hybrid and coimmunoprecipitation studies demonstrated that SLX2 interacts with BLOS2, which is a novel centrosome-associated protein, and co-localized with γ-Tubulin, which is a protein marker of chromosome segregation in meiosis. These results indicated that SLX2 might get involved in chromosomes segregation during meiosis by interaction with BLOS2. In conclusion, SLX2 might be a novel gametogenesis-related protein that could play multiple roles in regulation of meiotic processes including synaptonemal complex assembly and chromosome segregation.

Abstract
Protocatechuic acid (PCA), a phenolic compound of Radix Salviae Miltiorrhizae (RSM), has been found to have a protective effect on improving cognitive deficits in STZ-induced AD rats. The present study aimed to evaluate the potential protection activity of PCA on improving cognitive deficits and attenuating Aβ deposition and inflammatory responses in aged AβPP/PS1 double transgenic AD-model mice. The results of Morris water maze test showed that PCA (100mg/kg) significantly prolonged the mean latency time and the path length of AβPP/PS1 mice. PCA could significantly reduce the number of Aβ positive expressions in the hippocampus and cerebral cortex of AβPP/PS1 mice by immunocytochemical assay with Congo red staining and decrease remarkably APP expression level by Western blot analysis (P<0.01). The results from ELISA and Western blot analysis showed that the levels of inflammatory cytokines including TNF-α, IL-1β, IL-6 and IL-8 decreased remarkably by the treatment with PCA (P<0.01). Further, there was a substantial increase of brain derived neurotrophic factor (BDNF) in the hippocampus and cerebral cortex of AβPP/PS1 mice treated with PCA (P<0.01). The present study provided confirmatory evidence that PCA significantly decreased Aβ deposits, APP and inflammatory response, whereas increased learning and memory ability, as well as enhanced BDNF level. Our findings indicated that PCA is an effective neuroprotective agent for AD therapy. It might be associated with the attenuation on Aβ deposits and inflammation responses involved in the process.

Abstract
Intragenomic conflicts arise when a genetic element favours its own transmission to the detriment of others. Conflicts over sex chromosome transmission are expected to have influenced genome structure, gene regulation, and speciation. In the mouse, the existence of an intragenomic conflict between X- and Y-linked multicopy genes has long been suggested but never demonstrated. The Y-encoded multicopy gene Sly has been shown to have a predominant role in the epigenetic repression of post meiotic sex chromatin (PMSC) and, as such, represses X and Y genes, among which are its X-linked homologs Slx and Slxl1. Here, we produced mice that are deficient for both Sly and Slx/Slxl1 and observed that Slx/Slxl1 has an opposite role to that of Sly, in that it stimulates XY gene expression in spermatids. Slx/Slxl1 deficiency rescues the sperm differentiation defects and near sterility caused by Sly deficiency and vice versa. Slx/Slxl1 deficiency also causes a sex ratio distortion towards the production of male offspring that is corrected by Sly deficiency. All in all, our data show that Slx/Slxl1 and Sly have antagonistic effects during sperm differentiation and are involved in a postmeiotic intragenomic conflict that causes segregation distortion and male sterility. This is undoubtedly what drove the massive gene amplification on the mouse X and Y chromosomes. It may also be at the basis of cases of F1 male hybrid sterility where the balance between Slx/Slxl1 and Sly copy number, and therefore expression, is disrupted. To the best of our knowledge, our work is the first demonstration of a competition occurring between X and Y related genes in mammals. It also provides a biological basis for the concept that intragenomic conflict is an important evolutionary force which impacts on gene expression, genome structure, and speciation. Both copies of a gene have normally an equal chance of being inherited; however, some genes can act “selfishly” to be transmitted to >50% of offspring: a phenomenon known as transmission distortion. Distorting genes on the X or Y chromosome leads to an excess of female/male offspring respectively. This then sets up a “genomic conflict” (arms race) between the sex chromosomes that can radically affect their gene content. Male mice that have lost part of their Y produce >50% female offspring and show over-activation of multiple genes on the X, providing strong circumstantial evidence for distortion. Here, we demonstrate the existence of a genomic conflict regulated by the genes Slx/Slxl1 and Sly, present in ∼50 to 100 copies on the X and Y chromosomes respectively. SLX/SLXL1 and SLY proteins have antagonistic effects on sex chromosome expression in developing sperm and skew the offspring sex-ratio in favor of females/males. Interestingly, while deficiency of either gene alone leads to severe fertility problems, fertility is improved when both genes are deficient. We believe that the conflict in which Slx/Slxl1 and Sly are involved led to the amplification of X and Y genes and may have played an important role in mouse speciation.

Abstract
BACKGROUND Experiments were designed to identify the developmental expression and function of the Dickkopf-Like1 (DKKL1/Dkkl1) gene in humans and mice. METHODS Mouse testes cDNA samples were collected at multiple postnatal times (days 4, 9, 18, 35, and 54, as well as at 6 months) and hybridized to Affymetrix mouse whole genome Genechips. To further characterize the homologous gene DKKL1 in human beings, the expression profiles between human adult testis and foetal testis were compared using Affymetrix human Genechips. The characteristics of DKKL1/Dkkl1 were analysed using various cellular and molecular biotechnologies. RESULTS The expression of Dkkl1 was not detected in mouse testes on days 4 or 9, but was present on days 18, 35, and 54, as well as at 6 months, which was confirmed by RT-PCR and Western blot results. Examination of the tissue distribution of Dkkl1 demonstrated that while Dkkl1 mRNA was abundantly expressed in testes, little to no expression of Dkkl1 was observed in the epididymis or other tissues. In an in vitro fertilization assay, a Dkkl1 antibody was found to significantly reduce fertilization. Human Genechips results showed that the hybridization signal intensity of DKKL1 was 405.56-fold higher in adult testis than in foetal testis. RT-PCR analysis of multiple human tissues indicated that DKKL1 mRNA was exclusively expressed in the testis. Western blot analysis also demonstrated that DKKL1 was mainly expressed in human testis with a molecular weight of approximately 34 kDa. Additionally, immunohistochemical staining showed that the DKKL1 protein was predominantly located in spermatocytes and round spermatids in human testes. An examination of the expression levels of DKKL1 in infertile male patients revealed that while no DKKL1 appeared in the testes of patients with Sertoli cell only syndrome (SCOS) or cryptorchidism, DKKL1 was observed with variable expression in patients with spermatogenic arrest. CONCLUSIONS These results, together with previous studies, suggest that DKKL1/Dkkl1 may play an important role in testicular development and spermatogenesis and may be an important factor in male infertility.
