Y chromosomal noncoding RNAs regulate autosomal gene expression via piRNAs in mouse testis. BMC Biol 2021; 19:198.

Abstract
Background Deciphering the functions of Y chromosome in mammals has been slow owing to the presence of repeats. Some of these repeats transcribe coding RNAs, the roles of which have been studied. Functions of the noncoding transcripts from Y chromosomal repeats however, remain unclear. While a majority of the genes expressed during spermatogenesis are autosomal, mice with different deletions of the long arm of the Y chromosome (Yq) were previously also shown to be characterized by subfertility, sterility and sperm abnormalities, suggesting the presence of effectors of spermatogenesis at this location. Here we report a set of novel noncoding RNAs from mouse Yq and explore their connection to some of the autosomal genes expressed in testis. Results We describe a set of novel mouse male-specific Y long arm (MSYq)-derived long noncoding (lnc) transcripts, named Pirmy and Pirmy-like RNAs. Pirmy shows a large number of splice variants in testis. We also identified Pirmy-like RNAs present in multiple copies at different loci on mouse Y chromosome. Further, we identified eight differentially expressed autosome-encoded sperm proteins in a mutant mouse strain, XYRIIIqdel (2/3 Yq-deleted). Pirmy and Pirmy-like RNAs have homology to 5′/3′UTRs of these deregulated autosomal genes. Several lines of experiments show that these short homologous stretches correspond to piRNAs. Thus, Pirmy and Pirmy-like RNAs act as templates for several piRNAs. In vitro functional assays reveal putative roles for these piRNAs in regulating autosomal genes. Conclusions Our study elucidates a set of autosomal genes that are potentially regulated by MSYq-derived piRNAs in mouse testis. Sperm phenotypes from the Yq-deleted mice seem to be similar to that reported in inter-specific male-sterile hybrids. Taken together, this study provides novel insights into possible role of MSYq-derived ncRNAs in male sterility and speciation.

Low dose lead exposure at the onset of puberty disrupts spermatogenesis-related gene expression and causes abnormal spermatogenesis in mouse. Toxicol Appl Pharmacol 2020; 393:114942. [PMID: 32142724 DOI: 10.1016/j.taap.2020.114942] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2019] [Revised: 02/25/2020] [Accepted: 03/02/2020] [Indexed: 12/12/2022]
Abstract
Implications of lead (Pb) exposure in dysregulated spermatogenesis in sexually active individuals during adulthood is well established; however, the effect of Pb exposure on spermatogenesis in the early stages of puberty is not clear yet. Moreover, the mechanism of Pb mediated dysregulation of spermatogenesis in adults is also poorly understood. Exposure to environmental toxicants during puberty may cause serious consequences in adulthood causing developmental retardations, especially in the reproductive system. Here we investigated the effects of lead exposure on spermatogenesis at the onset of puberty and the underlying mechanisms of these effects. Male ICR mice were exposed to low (50 mg/L) and high (200 mg/L) doses of Pb through the drinking water for 90 days. At the end of this period, the blood Pb level of the low-dose and high-dose exposure groups were found 6.14 ± 0.34 μg/dL and 11.92 ± 2.92 μg/dL respectively which were in agreement with the US CDC-recommended (5 μg/dL) and Chinese CDC-recommended (10 μg/dL) reference blood Pb level for the children. Although no visible toxicity was observed in either group, Pb exposure caused considerable histopathological changes in testis and epididymis; increased sperm DNA fragmentation indices as well as disrupted sperm heads and head-neck conjunctions. Moreover, both low and high-dose Pb exposures caused aberrant expressions of several important spermatogenesis-related genes in epididymis and testis. These results suggest that although the blood Pb levels are close to the recommended-reference values, low dose Pb exposure at the onset of puberty can disrupt spermatogenesis-related gene expression and cause abnormal mouse spermatogenesis.

Abstract
Spermatogenesis is a complicated and dynamic cellular differentiation process mainly regulated by genes, steroid hormones and environmental factors. Although a number of genes involved in spermatogenesis have been identified, there are still a lot of genes underlying spermatogenesis remained unexplained. Here, a novel gene C4orf22, also known as 1700007G11Rik or Cfap299 was identified from mouse testis. C4orf22 protein contains 233 amino acid residues and is highly conserved in metazoan species. C4orf22 mRNA was predominantly expressed in mouse testis and increased from 2-week-old testes to 8-week-old testes during the developing testes by RT-PCR and qRT-PCR. Immunohistochemical analysis indicated that C4orf22 protein was mainly distributed in the cytoplasm of spermatogonia and primary spermatocytes, which was further confirmed by C4orf22-tagged with GFP in the GC-1 and GC-2 cells. Over-expression of pEGFP-C3-C4orf22 significantly inhibited GC-1 cells apoptosis and promoted cell cycle progression with an increase in the cell number of S and G2 phase. Conversely, small interfering RNA (siRNA) silencing C4orf22 in GC-1 cells could cause an increase in the number of apoptosis cells and the cell cycle was arrested at G2/M phase. Western blot analysis and qRT-PCR results showed that C4orf22 over-expression significantly increased the expressions of anti-apoptotic bcl-2 and decreased the expression of caspase-3, caspase-8 and Bax. Our results suggest that C4orf22 may be involved in spermatogenesis, and for the first time, unravels its potential role in regulating cell apoptosis through bcl-2 regulatory pathway in GC-1 cells.

Abstract
BACKGROUND Spermatogenesis in most mammals (including human and rat) occurs at ~ 3 °C lower than body temperature in a scrotum and fails rapidly at 37 °C inside the abdomen. The present study investigates the heat-sensitive transcriptome and miRNAs in the most vulnerable germ cells (spermatocytes and round spermatids) that are primarily targeted at elevated temperature in a bid to identify novel targets for contraception and/or infertility treatment. METHODS Testes of adult male rats subjected to surgical cryptorchidism were obtained at 0, 24, 72 and 120 h post-surgery, followed by isolation of primary spermatocytes and round spermatids and purification to > 90% purity using a combination of trypsin digestion, centrifugal elutriation and density gradient centrifugation techniques. RNA isolated from these cells was sequenced by massive parallel sequencing technique to identify the most-heat sensitive mRNAs and miRNAs. RESULTS Heat stress altered the expression of a large number of genes by ≥2.0 fold, out of which 594 genes (286↑; 308↓) showed alterations in spermatocytes and 154 genes (105↑; 49↓) showed alterations in spermatids throughout the duration of experiment. 62 heat-sensitive genes were common to both cell types. Similarly, 66 and 60 heat-sensitive miRNAs in spermatocytes and spermatids, respectively, were affected by ≥1.5 fold, out of which 6 were common to both the cell types. CONCLUSION The study has identified Acly, selV, SLC16A7(MCT-2), Txnrd1 and Prkar2B as potential heat sensitive targets in germ cells, which may be tightly regulated by heat sensitive miRNAs rno-miR-22-3P, rno-miR-22-5P, rno-miR-129-5P, rno-miR-3560, rno-miR-3560 and rno-miR-466c-5P.

Abstract
Azoospermia, oligospermia and teratozoospermia all seriously impact male reproductive health. Spermatogenesis is a complex and precisely regulated process in which germ cells proliferate and differentiate and involves the regulation of multiple testis-specific genes. Here, we identified testis-specific gene spermatogenesis-associated 48 (SPATA48), the expression of which was age-dependent, indicating that it is involved in spermatogenesis. In humans and mice with azoospermia, expression of SPATA48 disappeared in the testis. Spata48-/- knockout male mice had smaller testis and defective spermatogenesis compared to wild-type (WT) mice. This study can help in the exploration of the genetic basis of male infertility and identify new targets for the diagnosis and treatment of male infertility.

Transcriptome analysis of highly purified mouse spermatogenic cell populations: gene expression signatures switch from meiotic-to postmeiotic-related processes at pachytene stage. BMC Genomics 2016; 17:294.

Abstract
Background Spermatogenesis is a complex differentiation process that involves the successive and simultaneous execution of three different gene expression programs: mitotic proliferation of spermatogonia, meiosis, and spermiogenesis. Testicular cell heterogeneity has hindered its molecular analyses. Moreover, the characterization of short, poorly represented cell stages such as initial meiotic prophase ones (leptotene and zygotene) has remained elusive, despite their crucial importance for understanding the fundamentals of meiosis. Results We have developed a flow cytometry-based approach for obtaining highly pure stage-specific spermatogenic cell populations, including early meiotic prophase. Here we combined this methodology with next generation sequencing, which enabled the analysis of meiotic and postmeiotic gene expression signatures in mouse with unprecedented reliability. Interestingly, we found that a considerable number of genes involved in early as well as late meiotic processes are already on at early meiotic prophase, with a high proportion of them being expressed only for the short time lapse of lepto-zygotene stages. Besides, we observed a massive change in gene expression patterns during medium meiotic prophase (pachytene) when mostly genes related to spermiogenesis and sperm function are already turned on. This indicates that the transcriptional switch from meiosis to post-meiosis takes place very early, during meiotic prophase, thus disclosing a higher incidence of post-transcriptional regulation in spermatogenesis than previously reported. Moreover, we found that a good proportion of the differential gene expression in spermiogenesis corresponds to up-regulation of genes whose expression starts earlier, at pachytene stage; this includes transition protein-and protamine-coding genes, which have long been claimed to switch on during spermiogenesis. In addition, our results afford new insights concerning X chromosome meiotic inactivation and reactivation. Conclusions This work provides for the first time an overview of the time course for the massive onset and turning off of the meiotic and spermiogenic genetic programs. Importantly, our data represent a highly reliable information set about gene expression in pure testicular cell populations including early meiotic prophase, for further data mining towards the elucidation of the molecular bases of male reproduction in mammals.

Abstract
Although TiO2 nanoparticles (NPs) exposure has been demonstrated to cross blood-testis barrier and accumulate in the testis resulting in the reduction of sperm numbers, limited data with respect to the molecular mechanism of decreased spermatogenesis caused by TiO2 NP exposure. In this research, testicular damage, sperm number and alterations in testis-specific gene expressions in male mice induced by intragastric administration with TiO2 NPs for six months were investigated. It was found out that TiO2 NPs could migrate to cells, deposit in the testis and epididymis and thus cause damages to relevant organs, which are, to be more specific, the reductions of total sperm concentrations and sperm motility and an enhancement in the number of abnormal sperms in the cauda epididymis. Furthermore, the individual expression regarding to the mRNAs and proteins of testis-specific genes, including Cdc2, Cyclin B1, Dmcl, TERT, Tesmin, TESP-1, XPD and XRCCI, were significantly declined, whereas Gsk3-β and PGAM4 expressions were greatly elevated in mouse testis due to the exposures, which in fact implied that the reduced spermatogenesis may be involved in the alternated testis-specific gene expressions in those exposed male mice.

Abstract
Spermatogenesis is a complex developmental process in which undifferentiated spermatogonia are differentiated into spermatocytes and spermatids through two rounds of meiotic division and finally giving rise to mature spermatozoa (sperm). These processes involve many testis- or male germ cell-specific gene products that undergo strict developmental regulations. As a result, identifying critical, regulatory genes controlling spermatogenesis provide the clues not only to the regulatory mechanism of spermatogenesis at the molecular level, but also to the identification of candidate genes for infertility or contraceptives development. Despite the biological importance in male germ cell development, the underlying mechanisms of stage-specific gene regulation and cellular transition during spermatogenesis remain largely elusive. Previous genomic studies on transcriptome profiling were largely limited to protein-coding genes. Importantly, protein-coding genes only account for a small percentage of transcriptome; the majority are noncoding transcripts that do not translate into proteins. Although small noncoding RNAs (ncRNAs) such as microRNAs, siRNAs, and Piwi-interacting RNAs are extensively investigated in male germ cell development, the role of long ncRNAs (lncRNAs), commonly defined as ncRNAs longer than 200 bp, is relatively unexplored. Herein, we summarize recent transcriptome studies on spermatogenesis and show examples that a subset of noncoding transcript population, known as lncRNAs, constitutes a novel regulatory target in spermatogenesis.

Abstract
Mammalian testis development is a complex and highly sophisticated process. To study the dynamic change of normal testis development at the transcriptional level, we investigated mouse testes at three postnatal ages: 6 days postnatal, 4 weeks old, and 10 weeks old, representing infant (PN1), juvenile (PN2), and adult (PN3) stages, respectively. Using ultra high-throughput RNA sequencing (RNA-seq) technology, we obtained 211 million reads with a length of 35 bp. We identified 18837 genes that were expressed in mouse testes, and found that genes expressed at the highest level were involved in spermatogenesis. The gene expression pattern in PN1 was distinct from that in PN2 and PN3, which indicates that spermatogenesis has commenced in PN2. We analyzed a large number of genes related to spermatogenesis and somatic development of the testis, which play important roles at different developmental stages. We also found that the MAPK, Hedgehog, and Wnt signaling pathways were significantly involved at different developmental stages. These findings further our understanding of the molecular mechanisms that regulate testis development. Our study also demonstrates significant advantages of RNA-seq technology for studying transcriptome during development.

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.

Abstract
This study aims to clarify the relevance of tumor necrosis factor (TNFs) signaling pathways and liver regeneration (LR) at the cellular level. Eight liver cell types were isolated using Percoll density gradient centrifugation and immunomagnetic beads methods. Expressions of TNF signaling pathway-involved genes in each cell type after 2/3 hepatectomy (PH) were detected using gene chip. Results show the following: gene TNFα was upregulated in most cell types, especially in Kupffer cells (KC); TNFβ expression was insignificantly changed in eight liver cell types; the majority of genes involved in four TNFα signaling pathways showed increased expression during LR in hepatocytes (HC); TNFα-induced NFκB pathway-involved genes were upregulated preferentially between 2 and 24 h during LR in biliary epithelial cells (BECs); and TNFα-induced apoptotic pathway genes were downregulated preferentially at progressing phase of LR in dendritic cells (DCs). Referring to the above results, TNFα-mediated signaling pathways, in contrast to TNFβ, play the more proactive role in LR, and four TNFα-mediated signaling pathways seem helpful to regulate biological events in HC; BEC proliferation was partly controlled by TNFα-mediated NFκB pathway; and the impaired TNFα-mediated apoptotic pathway in DCs might contribute to the restoration of DC mass after PH. Briefly, the comparative analysis of genomewide expression profiles of TNF signaling pathways between different cell types is helpful in understanding the implication of TNF signaling in LR at the cellular level.

Abstract
The essential role of the Crem gene in normal sperm development is widely accepted and is confirmed by azoospermia in male mice lacking the Crem gene. The exact number of genes affected by Crem absence is not known, however a large difference has been observed recently between the estimated number of differentially expressed genes found in Crem knock-out (KO) mice compared to the number of gene loci bound by CREM. We therefore re-examined global gene expression in male mice lacking the Crem gene using whole genome transcriptome analysis with Affymetrix microarrays and compared the lists of differentially expressed genes from Crem−/− mice to a dataset of genes where binding of CREM was determined by Chip-seq. We determined the global effect of CREM on spermatogenesis as well as distinguished between primary and secondary effects of the CREM absence. We demonstrated that the absence of Crem deregulates over 4700 genes in KO testis. Among them are 101 genes associated with spermatogenesis 41 of which are bound by CREM and are deregulated in Crem KO testis. Absence of several of these genes in mouse models has proven their importance for normal spermatogenesis and male fertility. Our study showed that the absence of Crem plays a more important role on different aspects of spermatogenesis as estimated previously, with its impact ranging from apoptosis induction to deregulation of major circadian clock genes, steroidogenesis and the cell-cell junction dynamics. Several new genes important for normal spermatogenesis and fertility are down-regulated in KO testis and are therefore possible novel targets of CREM.

Abstract
Androgen and androgen receptor (AR) play important roles in male spermatogenesis and fertility, yet detailed androgen/AR signals in Sertoli cells remain unclear. To identify AR target genes in Sertoli cells, we analyzed the gene expression profiles of testis between mice lacking AR in Sertoli cells (S-AR(-/y)) and their littermate wild-type (WT) mice. Digital gene expression analysis identified 2276 genes downregulated and 2865 genes upregulated in the S-AR(-/y) mice testis compared to WT ones. To further nail down the difference within Sertoli cells, we first constructed Sertoli cell line TM4 with stably transfected AR (named as TM4/AR) and found androgens failed to transactivate AR in Sertoli TM4 and TM4/AR cells. Interestingly, additional transient transfection of AR-cDNA resulted in significant androgen responsiveness with TM4/AR cells showing 10 times more androgen sensitivity than TM4 cells. In the condition where maximal androgen response was demonstrated, we then analyzed gene expression and found the expression levels of 2313 genes were changed more than twofold by transient transfection of AR-cDNA in the presence of testosterone. Among these genes, 603 androgen-/AR-regulated genes, including 164 upregulated and 439 downregulated, were found in both S-AR(-/y) mice testis and TM4/AR cells. Using informatics analysis, the gene ontology was applied to analyze these androgen-/AR-regulated genes to predict the potential roles of androgen/AR in the process of spermatogenesis. Together, using gene analysis in both S-AR(-/y) mice testis and TM4/AR cells may help us to better understand the androgen/AR signals in Sertoli cells and their influences in spermatogenesis.

Abstract
To identify the developmental expression of the ACRV1 gene in humans and mice, testes cDNA samples were collected at different post-natal days (days 4, 9, 18, 35, 54, and 6 months) from Balb/c mice and were hybridised to the mouse whole genome 430 2.0 Array (Affymetrix Inc.) chip. The characteristics of ACRV1 were analysed using various cellular and molecular biotechnologies. The results showed that the expression of mouse ACRV1 was not detected in mouse testes on days 4, 9, and 18 but was present on days 35, 54, and 6 months. Using RT-PCR analysis of mouse ACRV1, we determined that mouse ACRV1 was expressed specifically in the mouse testis, and its expression began at days 35. Western blot analysis demonstrated that human ACRV1 was primarily expressed in human testes, and immunofluorescent and immunohistochemistry staining showed that human ACRV1 protein was predominantly located in round and elongated spermatids in human testes, indicating that ACRV1 may play an important role in mammalian spermatogenesis and may be a target of a contraceptive vaccine.

Abstract
To explore glutamine family amino acid metabolism of eight liver cell types in rat liver regeneration, eight kinds of rat regenerating liver cells were isolated by using the combination of Percoll density gradient centrifugation and immunomagnetic bead methods, then Rat Genome 230 2.0 Array was used to detect the expression profiles of the genes associated with metabolism of glutamine family amino acid in rat liver regeneration and finally how these genes involved in activities of eight regenerating liver cell types were analysed by the methods of bioinformatics and systems biology. The results showed that in the priming stage of liver regeneration, hepatic stellate cells and sinusoidal endothelial cells transformed proline and glutamine into glutamate; hepatocytes, hepatic stellate cells, sinusoidal endothelial cells and dendritic cells catabolized glutamate to 2-oxoglutarate or succinate; hepatic stellate cells and sinusoidal endothelial cells catalysed glutamate into glutamyl-tRNA for protein synthesis; urea cycle, which degraded from arginine, was enhanced in biliary epithelia cells, sinusoidal endothelial cells and dendritic cells; synthesis of polyamines from arginine was enhanced in biliary epithelia cells, sinusoidal endothelial cells, Kupffer cells and dendritic cells; the content of NO was increased in sinusoidal endothelial cells and dendritic cells; degradation of proline was enhanced in hepatocytes and biliary epithelia cells. In the progress stage, biliary epithelia cells converted glutamine into GMP and glucosamine 6-phosphate; oval cells converted glutamine into glucosamine 6-phosphate; hepatic stellate cells converted glutamine into NAD; the content of NO, which degraded from arginine, was increased in biliary epithelia cells, oval cells, pit cells and dendritic cells. In the termination stage, oval cells converted proline into glutamate; glutamate degradation, which degraded from arginine, was enhanced in hepatocytes and dendritic cells; the content of NO was increased in oval cells, sinusoidal endothelial cells, pit cells and dendritic cells. The synthesis of creatine phosphate was enhanced in hepatocytes, biliary epithelia cells, pit cells and dendritic cells in both progress and termination stages. In summary, glutamine family amino acid metabolism has some differences in liver regeneration in different liver cells.

Abstract
This study performed a large-scale, high-throughput analysis of transcriptional profiling of liver stellate cells (LSCs) at the cellular level to investigate changes in the biological activity of LSCs during rat liver regeneration (LR) and the relation of these changes to LR. First, a rat liver regeneration model was established by partial hepatectomy (PH). Stellate cells were isolated in high purity and yield from the regenerating rat liver by Percoll density gradient centrifugation and immunomagnetic bead sorting. The changes in gene expression of LSCs after PH were examined using a rat genome 230 2.0 array composed of 24622 genes. The results indicated that 10241 of the 24622 genes investigated on the array were differentially expressed in LSCs. Of the 10241 genes, 1563 known genes were related to LR, which were grouped into three major gene expression clusters according to three-fold cut-off threshold: the upregulated gene cluster, the down-regulated gene cluster, and the cluster composed of genes showing complex changes in expression. Additionally, the genes were grouped into those involved in transcription regulation, signal transduction, transport, cellular metabolism, inflammation and immunity by functional analysis. When gene expression profiles were combined with the results of gene functional analysis, most of the genes involved in cytokine secretion and retinol metabolism in LSCs were significantly enriched in the cluster characterized by decreased expression, whereas genes involved in lipid metabolism were mostly enriched in the cluster showing increased expression. Based on further analysis of genes expressed in a phase-dependent manner during LR, it was suggested that lipid metabolism in LSCs was enhanced in the whole regeneration process, and that immune response and cytokine secretion were impaired during all three regenerative phases.

Abstract
In the dogfish testis, the cystic arrangement and polarization of germ cell stages make it possible to observe all stages of spermatogenesis in a single transverse section. By taking advantage of the zonation of this organ, we have used suppressive subtractive libraries construction, real-time PCR, and in situ hybridization to identify 32 dogfish genes showing differential expressions during spermatogenesis. These include homologs of genes already known to be expressed in the vertebrate testis, but found here to be specifically expressed either in pre-meiotic and/or meiotic zones (ribosomal protein S8, high-mobility group box 3, ubiquitin carboxyl-terminal esterase L3, 20beta-hydroxysteroid dehydrogenase, or cyclophilin B) or in post-meiotic zone (speriolin, Soggy, zinc finger protein 474, calreticulin, or phospholipase c-zeta). We also report, for the first time, testis-specific expression patterns for dogfish genes coding for A-kinase anchor protein 5, ring finger protein 152, or F-box only protein 7. Finally, the study highlights the differential expression of new sequences whose identity remains to be assessed. This study provides the first molecular characterization of spermatogenesis in a chondrichthyan, a key species to gain insight into the evolution of this process in gnathostomes.

Abstract
A novel gene, TSG23/Tsg23, was identified by comparing the expression profiles of human adult and fetal testis using Affymetrix Genechips. RT-PCR analysis from multiple human and mouse tissues indicated TSG23/Tsg23 mRNA was mainly expressed in the testis. In situ hybridization revealed that TSG23/Tsg23 mRNA was located in spermatocytes and round spermatids of the seminiferous tubules in human and mouse testis. To further confirm the result from RT-PCR, the antibody for human TSG23 was generated against the protein encoded by the gene. Western blot analysis demonstrated that TSG23 was mainly expressed in human testis, with a molecular weight of about 23 kDa. Immunohistochemistry showed that TSG23 was predominantly located in spermatocytes and round spermatids, consistent with the results from in situ hybridization. In order to explore the function of TSG23 in spermatogenesis, the study compared the expression of TSG23 in the testis from fertile persons and from patients with azoospermia. The results showed that there was less expression in patients with obstructive azoospermia compared with fertile persons, and no detectable TSG23 at mRNA and protein levels in patients with non-obstructive azoospermia. The expression of Tsg23 mRNA was considerably decreased in a time-dependent manner in the testis of an azoospermic mouse model induced by Busulfan. These data suggest that TSG23/Tsg23 is involved in human and mouse spermatogenesis.

PLoS One 2008; 3:e3915.

Abstract
Background The fish medaka is the first vertebrate capable of full spermatogenesis in vitro from self-renewing spermatogonial stem cells to motile test-tube sperm. Precise staging and molecular dissection of this process has been hampered by the lack of suitable molecular markers. Methodology and Principal Findings We have generated a normalized medaka testis cDNA library and obtained 7040 high quality sequences representing 3641 unique gene clusters. Among these, 1197 unique clusters are homologous to known genes, and 2444 appear to be novel genes. Ontology analysis shows that the 1197 gene products are implicated in diverse molecular and cellular processes. These genes include markers for all major types of testicular somatic and germ cells. Furthermore, markers were identified for major spermatogenic stages ranging from spermatogonial stem cell self-renewal to meiosis entry, progression and completion. Intriguingly, the medaka testis expresses at least 13 homologs of the 33 mouse X-chromosomal genes that are enriched in the testis. More importantly, we show that key components of several signaling pathways known to be important for testicular function in mammals are well represented in the medaka testicular EST collection. Conclusions/Significance Medaka exhibits a considerable similarity in testicular gene expression to mammals. The medaka testicular EST collection we obtained has wide range coverage and will not only consolidate our knowledge on the comparative analysis of known genes' functions in the testis but also provide a rich resource to dissect molecular events and mechanism of spermatogenesis in vivo and in vitro in medaka as an excellent vertebrate model.
