Diawara M, Martin LJ. Regulatory mechanisms of SoxD transcription factors and their influences on male fertility. Reprod Biol 2023; 23:100823.

Abstract
Members of the SRY-related box (SOX) subfamily D (SoxD) of transcription factors are well conserved among vertebrate species and play important roles in different stages of male reproductive development. In mammals, the SoxD subfamily contains three members: SOX5, SOX6 and SOX13. Here, we describe their implications in testicular development and spermatogenesis, contributing to fertility. We also cover the mechanisms of action of SoxD transcription factors in gene regulation throughout male development. The specificity of activation of target genes by SoxD members depends, in part, on their post-translational modifications and interactions with other partners. Sperm production in adult males requires the coordination in the regulation of gene expression by different members of the SoxD subfamily of transcription factors in the testis. Specifically, the regulation of genes promoting adequate spermatogenesis by SoxD members is discussed in comparison between species.

Genome-wide identification and annotation of SNPs and their mapping in candidate genes related to milk production and fertility traits in Badri cattle. Trop Anim Health Prod 2023; 55:117. [PMID: 36928332 DOI: 10.1007/s11250-023-03535-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Accepted: 03/06/2023] [Indexed: 03/18/2023]
Abstract
This study was conducted in Badri cattle using a double digest restriction-site associated DNA sequencing approach. The study aimed to identify and annotate high confidence single nucleotide polymorphisms (SNPs) and their mapping in candidate genes related to production and fertility in dairy cattle. A total of 7,168,552 genome-wide SNPs were initially identified in Badri cattle by alignment with the Bos indicus reference genome. After filtration of SNPs, 65,483 high confidence SNPs were retained and further used for downstream analysis. Annotation of high confidence SNPs revealed 99.197% SNPs had modifier impact, 0.326% SNPs were low impact, 0.036% were high impact, and 0.441% were moderate impact SNPs. Most SNPs in Badri cattle were found in intergenic, transcript and intronic regions. The candidate genes for milk production PRKCE, ABCG2, GHR, EPS8, CAST and NRXN1 were found to harbour maximum high confidence variants. Among candidate genes for fertility in cattle, ATP2B1, SOX5, WDR27, ARHGAP12, CACNA1D, ANKRD6, GRIA3, ZNF521 and CAST822 have maximum high confidence variants mapped in them. The SNPs found mapped in the candidate genes will be important genetic tools in the search for phenotype-modifying nucleotide changes and will aid in formulating relevant genetic improvement programmes for dairy cattle.

Multi-breed genomic predictions and functional variants for fertility of tropical bulls. PLoS One 2023; 18:e0279398.

Abstract
Worldwide, most beef breeding herds are naturally mated. As such, the ability to identify and select fertile bulls is critically important for both productivity and genetic improvement. Here, we collected ten fertility-related phenotypes for 6,063 bulls from six tropically adapted breeds. Phenotypes were comprised of four bull conformation traits and six traits directly related to the quality of the bull's semen. We also generated high-density DNA genotypes for all the animals. In total, 680,758 single nucleotide polymorphism (SNP) genotypes were analyzed. The genomic correlation of the same trait observed in different breeds was positive for scrotal circumference and sheath score on most breed comparisons, but close to zero for the percentage of normal sperm, suggesting a divergent genetic background for this trait. We confirmed the importance of a breed being present in the reference population to the generation of accurate genomic estimated breeding values (GEBV) in an across-breed validation scenario. Average GEBV accuracies varied from 0.19 to 0.44 when the breed was not included in the reference population. The range improved to 0.28 to 0.59 when the breed was in the reference population. Variants associated with the gene HDAC4, six genes from the spermatogenesis-associated (SPATA) family of proteins, and 29 transcription factors were identified as candidate genes. Collectively these results enable very early in-life selection for bull fertility traits, supporting genetic improvement strategies currently taking place within tropical beef production systems. This study also improves our understanding of the molecular basis of male fertility in mammals.

AIRE in Male Fertility: A New Hypothesis. Cells 2022; 11:cells11193168.

Abstract
Male infertility affects approximately 14% of all European men, of which ~44% are characterized as idiopathic. There is an urgency to identify the factors that affect male fertility. One such factor, Autoimmune Regulator (AIRE), a protein found in the thymus, has been studied in the context of central tolerance functioning as a nuclear transcription modulator, responsible for the expression of tissue-restricted antigens in specialized thymic cells that prevent autoimmunity. While its expression in the testes remains enigmatic, we recently observed that sterility in mice correlates with the absence of Aire in the testes, regardless of the deficient expression in medullary thymic epithelial cells or cells of the hematopoietic system. By assessing the Aire transcript levels, we discovered that Sertoli cells are the exclusive source of Aire in the testes, where it most likely plays a non-immune role, suggesting an unknown mechanism by which testicular Aire regulates fertility. Here, we discuss these results in the context of previous reports which have suggested that infertility observed in Aire deficient mice is of an autoimmune aetiology. We present an alternative point of view for the role of Aire in testes in respect to fertility altering the perspective of how Aire's function in the testes is currently perceived.

Abstract
The CatSper channel localizes exclusively in the flagella of sperm cells. The Catsper1 protein, together with three pore units, is essential for the CatSper Channel formation, which produces flagellum hyperactivation and confers sperm fertility. Catsper1 expression is dependent on Sox transcription factors, which can recognize in vitro at least three Sox binding sites on the promoter. Sox transcription factors have calmodulin-binding domains for nuclear importation. Calmodulin (CaM) is affected by the specific inhibitor calmidazolium (CMZ), which prevents the nuclear transport of Sox factors. In this work, we assess the regulation of the Catsper1 promoter in vivo by Sox factors in the murine testis and evaluate the effects of the inhibitor calmidazolium on the expression of the Casper genes, and the motility and fertility of the sperm. Catsper1 promoter has significant transcriptional activity in vivo; on the contrary, three Sox site mutants in the Catsper1 promoter reduced transcriptional activity in the testis. CaM inhibition affects Sox factor nuclear transport and has notable implications in the expression and production of Catsper1, as well as in the motility and fertility capability of sperm. The molecular mechanism described here might conform to the basis of a male contraceptive strategy acting at the transcriptional level by affecting the production of the CatSper channel, a fundamental piece of male fertility.

Genes Genomics 2022; 44:1415-1424.

Abstract
BACKGROUND Colorectal cancer (CRC) is one of the most common malignant tumors and the fourth leading cause of cancer death worldwide. Constitutive activation of the PI3K/AKT signaling pathway is a hallmark of colon tumor growth. CATSPER1 gene encodes a pore-forming and pH-sensing subunit of the CatSper Ca2+-permeable channel, a sperm-specific calcium channel essential for hyperactivated motility and male fertility. However, the function of CATSPER1 outside the male reproductive system is unclear. OBJECTIVE This study was designed to explore whether CatSper exerted its functional role in the progress of CRC, and investigate the possible mechanisms. METHODS Microarray data (GSE146587) from 6 patients diagnosed with stage III CRC post-surgery was analyzed by Limma R package. The Kaplan Meier plotter (KM plotter) database was used to assess the relevance of CATSPER1 mRNA expression to the overall survival (OS) rates in CRC. Western blot, real-time PCR and luciferase reporter assays were used to determine the SOX11-CATSPER1 axis in CRC cells. Clustered regularly interspaced short palindromic repeats (CRISPR)-based gene editing was used to generate CATSPER1 knockout (KO) CRC cells. The proliferation of CRC cells was determined by BrdU incorporation and colony formation assays. The effect of CATSPER1 on CRC tumor growth in vivo was investigated in a mice tumor xenograft model. RESULTS Here, we show that CATSPER1 expression was significantly up-regulated in CRC and elevated CATSPER1 was associated with poor overall survival (OS). Moreover, the transcription factor SOX11 (SRY-related high-mobility-group (HMG) box 11) activated CATSPER1 transcription in CRC cells. Functionally, we showed that CATSPER1 promoted CRC cells proliferation both in vitro and in vivo. At the molecular level, we demonstrated that CATSPER1 might maintain CRC malignant process partly through the activation of the PI3K/AKT signaling pathway. CONCLUSION Increased CATSPER1 expression facilitates CRC cells proliferation, suggesting that targeting CATSPER1 might represent a promising strategy for colon cancer treatment.

Abstract
INTRODUCTION Broccoli (Brassica oleracea) is well known for its properties as an anticancer, antioxidant, and scavenger of free radicals. However, its benefits in enhancing spermatogenesis have not been well established. OBJECTIVE To study broccoli aqueous extract effects on sperm factors and the expression of genes Catsper1, Catsper2, Arl4a, Sox5, and Sox9 in sperm factors in mice. MATERIAL AND METHODS Male mice were divided randomly into six groups: (1) Control; (2) cadmium (3 mg/kg of mouse body weight); (3) orally treated with 200 μl broccoli aqueous extract (1 g ml-1); (4) orally treated with 400 μl of broccoli aqueous extract; (5) orally treated with 200 broccoli aqueous extract plus cadmium, and (6) orally treated with 400 μl of broccoli aqueous extract plus cadmium. We analyzed the sperms factors and Catsper1, Catsper2, Arl4a, Sox5, and Sox9 gene expression. RESULTS An obvious improvement in sperm count and a slight enhancement in sperm motility were observed in mice treated with broccoli extract alone or with cadmium. Sperm viability was reduced by broccoli extract except for the 200 μl dose with cadmium, which significantly increased it. Interestingly, Arl4a gene expression increased in the 400 μl broccoli-treated group. Likewise, the Arl4a mRNA level in mice treated with cadmium and 200 μl of broccoli extract was higher than in the cadmium-treated mice. Furthermore, broccoli extract enhanced the mRNA level of Catsper2 and Sox5 genes in mice treated with 200 μl and 400 μl broccoli extract plus cadmium compared with the group treated solely with cadmium. CONCLUSION The higher sperm count in broccoli-treated mice opens the way for the development of pharmaceutical products for infertile men.

Abstract
BACKGROUND Intensive research on sperm ion channels has identified members of several ion channel families in both mouse and human sperm. Gene knock-out studies have unequivocally demonstrated the importance of the calcium and potassium conductances in sperm for fertility. In both species, the calcium current is carried by the highly complex cation channel of sperm (CatSper). In mouse sperm, the potassium current has been conclusively shown to be carried by a channel consisting of the pore forming subunit SLO3 and auxiliary subunit leucine-rich repeat-containing 52 (LRRC52). However, in human sperm it is controversial whether the pore forming subunit of the channel is composed of SLO3 and/or SLO1. Deciphering the role of the proton-specific Hv1 channel is more challenging as it is only expressed in human sperm. However, definitive evidence for a role in, and importance for, human fertility can only be determined through studies using clinical samples. OBJECTIVE AND RATIONALE This review aims to provide insight into the role of sperm ion channels in human fertilization as evidenced from recent studies of sperm from infertile men. We also summarize the key discoveries from mouse ion channel knock-out models and contrast the properties of mouse and human CatSper and potassium currents. We detail the evidence for, and consequences of, defective ion channels in human sperm and discuss hypotheses to explain how defects arise and why affected sperm have impaired fertilization potential. SEARCH METHODS Relevant studies were identified using PubMed and were limited to ion channels that have been characterized in mouse and human sperm. Additional notable examples from other species are included as appropriate. OUTCOMES There are now well-documented fundamental differences between the properties of CatSper and potassium channel currents in mouse and human sperm. However, in both species, sperm lacking either channel cannot fertilize in vivo and CatSper-null sperm also fail to fertilize at IVF. Sperm-lacking potassium currents are capable of fertilizing at IVF, albeit at a much lower rate. However, additional complex and heterogeneous ion channel dysfunction has been reported in sperm from infertile men, the causes of which are unknown. Similarly, the nature of the functional impairment of affected patient sperm remains elusive. There are no reports of studies of Hv1 in human sperm from infertile men. WIDER IMPLICATIONS Recent studies using sperm from infertile men have given new insight and critical evidence supporting the supposition that calcium and potassium conductances are essential for human fertility. However, it should be highlighted that many fundamental questions remain regarding the nature of molecular and functional defects in sperm with dysfunctional ion channels. The development and application of advanced technologies remains a necessity to progress basic and clinical research in this area, with the aim of providing effective screening methodologies to identify and develop treatments for affected men in order to help prevent failed ART cycles. Conversely, development of drugs that block calcium and/or potassium conductances in sperm is a plausible strategy for producing sperm-specific contraceptives.

Abstract
Mud crab (Scylla paramamosain) is one of the most economically-important marine crabs in China. However, research on mechanisms of reproductive regulation is not sufficient. Vitellogenesis-inhibiting hormone (VIH) is a member of the crustacean hyperglycemia hormones (CHH) family, which plays an essential role in the regulation of gonadal development and maturation in crustaceans, and current studies on the regulation of Vih transcription in crabs are relatively rare. Our previous studies on the transcriptional regulation of mud crab Vih (SpVih) have proved that the binding site of Oct4/Sox9 transcription factor may be the key region for positively regulating the expression of SpVih. In this study, the electrophoretic mobility shift assay (EMSA) experiment confirmed that the nuclear protein extracted from the eyestalk could bind to the key region of SpVih promoter, and these specific bindings were dependent on the presence of Oct4/Sox9 binding sites. Two specific binding complex bands were detected in the supershift group of EMSA supershift experiments by Oct4 and Sox9 antibodies, further confirming the specific recognition of these two transcription factors on the key regulatory region of SpVih. In vitro, Oct4 and Sox9 gene overexpression vectors and SpVih core promoter fragment vector were constructed and co-transfected into HEK293T cells. As a result, SpVih activity increased with the concentration of transcription factors. In vivo, when Oct4 and Sox9 dsRNA were injected into the eyestalks of mud crab, respectively, the expression level of SpVih decreased significantly after interference with Oct4 or Sox9, and the expression level of SpVtg in the ovary and hepatopancreatic increased. Both in vitro and in vivo experiments showed that Oct4 and Sox9 had a positive regulatory effect on SpVih. The GST pull-down experiment was carried out by purified Oct4 and Sox9 proteins, and the results showed that there was an interaction between them. It was speculated that they regulated the expression of SpVih through the interaction.

Abstract
Endogenous retroviruses (ERVs) have been identified at different copy numbers in various organisms. The long terminal repeat (LTR) element of an ERV has the capacity to exert regulatory influence as both a promoter and enhancer of cellular genes. Here, we describe olive flounder (OF)-ERV9, derived from chromosome 9 of the olive flounder. OF-ERV9-LTR provide binding sites for various transcription factors and showed enhancer activity. The OF-ERV9-LTR demonstrates high sequence similarity with the 3' untranslated region (UTR) of various genes that also contain seed sequences (TGTTTTG) that bind the LTR-derived microRNA(miRNA), OF-miRNA-307. Additionally, OF-miRNA-307 collaborates with transcription factors located in OF-ERV9-LTR to regulate gene expression. Taken together, our data facilitates a greater understanding of the molecular function of OF-ERV families and suggests that OF-miRNA-307 may act as a super-enhancer miRNA regulating gene activity.

Regulation of CATSPER1 expression by the testis-determining gene SRY. PLoS One 2018; 13:e0205744.

Abstract
CATSPER1 gene encodes a pore-forming and pH-sensing subunit of the CatSper Ca2+- permeable channel, a protein in the flagellum essential for sperm hyperactivation. Previous studies have shown that the murine Catsper1 gene promoter is regulated by different Sox proteins. Likewise, it is acknowledged that the human CATSPER1 gene promoter sequence is enriched in potential interaction sites for the sex-determining region Y gene (SRY), which suggest a novel regulatory transcriptional mechanism for CatSper1 channel expression. Therefore, in this work, we sought to determine whether the human CATSPER1 gene expression is regulated by the SRY transcription factor. To this end, a series of deletions and mutations were introduced in the wild- type CATSPER1 gene promoter to eliminate the SRY sites, and the different constructs were tested for their ability to activate transcription in human embryonic kidney and murine spermatogonial germ cell lines (HEK-293 and GC1-spg, respectively) using luciferase assays. In addition, by using a strategy that combines electrophoretic mobility shift assays (EMSA) and chromatin immunoprecipitation (ChIP) we investigated whether the CATSPER1 gene expression is regulated by the SRY transcription factor both in vitro and in vivo. Our results show that the transcriptional factor SRY specifically binds to different sites in the promoter sequence and has the ability to control CATSPER1 gene transcription.

Human CATSPER1 Promoter Is Regulated by CREB1 and CREMτ Transcriptional Factors In Vitro. Arch Med Res 2018; 49:135-146. [PMID: 30017233 DOI: 10.1016/j.arcmed.2018.06.004] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2017] [Accepted: 06/26/2018] [Indexed: 11/22/2022]
Abstract
BACKGROUND The CATSPER1 gene encodes a CATSPER channel protein that selectively permeates Ca2+ ions, and CATSPER expression in sperm is essential for flagellum hyperactivation and, thus, male fertility. Little is known regarding the transcriptional regulation of CATSPER1, but previous studies have performed in silico analyses of transcription factor binding sites, including three CRE sites designated 0-2, in which CRE0 is located near the transcription start site. OBJETIVES We investigate if overexpression of CREB-A and CREMτ transcription factors might regulate CATSPER1 expression. MATERIAL AND METHODS In this study, the transcriptional regulation of the CATSPER1 gene by CREB-A and CREMτ transcriptions factors was determined by dual-luciferase assays in HEK293 and GC1-spg cells, and important CRE sites were mutated and analyzed for transcriptional regulation. RESULTS The deletion of the CRE1 site dramatically increased the transcriptional activity of the CATSPER1 promoter in HEK293 and GC1-spg cells. In HEK293 cells, the CREB-A transcription factor positively regulated CATSPER1 gene expression, while the presence of CREB-A and CREMτ factors synergistically enhanced promoter activity in these cells. In contrast, deletion of CRE0 prevented any transcriptional activity of the CATSPER1 promoter in GC1-spg spermatogonial cells, but expression of either CREB-A or CREMτ restored such transcriptional activity. CONCLUSIONS The human CATSPER1 promoter is positively regulated in vitro by CREB-A in HEK293 and GC1-spg cells. Both lines showed differential transcriptional regulation, which was defined by the factors and coactivators present in each cell line as well as the context in which the CRE sites were found in the promoter.

Abstract
Use of information theory can be an alternative statistical approach to detect genome regions and candidate genes that are associated with livestock traits. The aim of this study was to verify the validity of the SNPs effects on some semen quality variables of bulls using entropy analysis. Records from 288 Holstein-Friesian bulls from one AI station were included. The following semen quality variables were analyzed: CASA kinematic variables of sperm (total motility, average path velocity, straight line velocity, curvilinear velocity, amplitude of lateral head displacement, beat cross frequency, straightness, linearity), sperm membrane integrity (plazmolema, mitochondrial function), sperm ATP content. Molecular data included 48,192 SNPs. After filtering (call rate = 0.95 and MAF = 0.05), 34,794 SNPs were included in the entropy analysis. The entropy and conditional entropy were estimated for each SNP. Conditional entropy quantifies the remaining uncertainty about values of the variable with the knowledge of SNP. The most informative SNPs for each variable were determined. The computations were performed using the R statistical package. A majority of the loci had relatively small contributions. The most informative SNPs for all variables were mainly located on chromosomes: 3, 4, 5 and 16. The results from the study indicate that important genome regions and candidate genes that determine semen quality variables in bulls are located on a number of chromosomes. Some detected clusters of SNPs were located in RNA (U6 and 5S_rRNA) for all the variables for which analysis occurred. Associations between PARK2 as well GALNT13 genes and some semen characteristics were also detected.

Abstract
Vitellogenesis-inhibiting hormone (VIH) is known to regulate ovarian maturation by suppressing the synthesis of vitellogenin (Vtg) in crustaceans, which belongs to a member of crustacean hyperglycemic hormone (CHH) family synthesized and secreted from the X-organ/sinus gland complex of eyestalks. In this study, the cDNA, genomic DNA (gDNA) and the 5'-upstream regulatory (promoter region) sequences of VIH gene were obtained by conventional PCR, genome walker and tail-PCR techniques according to our transcriptomic database of Scylla paramamosain. The full-length cDNA of SpVIH is 634bp including 105bp 5'UTR, 151bp 3'UTR and 378bp ORF that encodes a peptide of 125 amino acids. The full length gDNA of SpVIH is 790bp containing two exons and one intron. The 5'-flanking promoter regions of SpVIH we isolated are 3070bp from the translation initiation (ATG) and 2398bp from the predicted transcription initiation (A), which consists of putative core promoter region and multiple potential transcription factor binding sites. SpVIH was only expressed in eyestalk. The expression level of SpVIH in eyestalk of female crab decreased gradually along with the development of ovary. As there is not cell line of crabs available, we chose the mature transfection system HEK293FT cell lines to explore the mechanism of transcription regulation of SpVIH in crabs. Sequential deletion assays using luciferase reporter gene in HEK293FT cells revealed that the possible promoter activity regions (including positive and negative transcription factors binding sites simultaneously) presented between pSpVIH-4 and pSpVIH-6. In order to further identify the crucial transcription factors binding site in this region, the site-directed mutagenesis of Sox9/Oct4/Oct1 binding site of pSpVIH-4 was created. The results demonstrated that the transcriptional activity of pSpVIH-4△ decreased significantly (p<0.05). Thus, it is reasonable to deduce that the Sox9/Oct4/Oct1 may be the essential positive transcription factors which regulate the expression of SpVIH.

Abstract
Long non-coding RNA (lncRNA) dysregulation is involved in tumorigenesis and regulation of diverse cellular processes in gliomas. lncRNA SNHG12 is upregulated and promotes cell growth in human osteosarcoma cells. TAR-DNA binding protein 43 (TDP43) functions as an oncogene in various tumors by modulating RNA expression. Downregulation of TDP43 or SNHG12 significantly inhibited malignant biological behaviors of glioma cells. miR-195, downregulated in glioma tissues and cells, significantly impaired the malignant progression of glioma cells. TDP43 upregulated miR-195 in an SNHG12-dependent manner. We further revealed that SNHG12 and miR-195 were in an RNA-induced silencing complex (RISC). Inhibition of SNHG12 combined with restoration of miR-195 robustly reduced tumor growth in vivo. SOX5 was overexpressed in glioma tissues and cells. miR-195 targeted SOX5 3′ UTR in a sequence-specific manner. Gelsolin was activated by SOX5. More importantly, SOX5 activated SNHG12 promoter and upregulated its expression, forming a feedback loop. Dysregulation of SNHG12, miR-195, and SOX5 predicted poor prognosis of glioma patients. The present study demonstrated that SNHG12-miR-195-SOX5 feedback loop exerted a crucial role in the regulation of glioma cells’ malignant progression.

Abstract
Background: Metastatic castration-resistant prostate cancer (mCRPC) is one of the main contributors to the death of prostate cancer patients. To date, the detailed molecular mechanisms underlying mCRPC are unclear. Given the crucial role of epithelial–mesenchymal transition (EMT) in cancer metastasis, we aimed to analyse the expression and function of Transforming growth factor-beta (TGF-β) signal-associated protein named Sox5 in mCRPC. Methods: The protein expression levels were analysed by western blot, immunohistochemistry and immunofluorescence. Luciferase reporter assays and chromatin immunoprecipitation were employed to validate the target of Sox5. The effect of Smad3/Sox5/Twist1 on PCa progression was investigated in vitro and in vivo. Results: Here, we found that TGF-β-induced EMT was accompanied by increased Sox5 expression. Interestingly, knockdown of Sox5 expression attenuated EMT induced by TGF-β signalling. Furthermore, we demonstrated that Smad3 could bind to the promoter of Sox5 and regulate its expression. Mechanistically, Sox5 could bind to Twist1 promoter and active Twist1, which initiated EMT. Importantly, knockdown of Sox5 in prostate cancer cells resulted in less of the mesenchymal phenotype and cell migration ability. Furthermore, targeting Sox5 could inhibit prostate cancer progression in a xenograft mouse model. In clinic, patients with high Sox5 expression were more likely to suffer from metastases, and high Sox5 expression also has a lower progression-free survival and cancer specific-survival in clinic database. Conclusions: Therefore, we propose a new mechanism in which Smad3/Sox5/Twist1 promotes EMT and contributes to PCa progression.

Abstract
Legg-Calvé-Perthes disease (LCPD) commonly onsets in adolescents, and threatens their health. However, the potential mechanism underlying LCPD remains unclear. MicroRNA (miR)-206 and SRY-box 9 (SOX9) serve an important role in chondrocytes; however, their role in LCPD remains ambiguous. In the present study, whether miR-206 and SOX9 mediated cell apoptosis in dexamethasone (DEX)-induced LCPD was investigated. The chondrocytes of the LCPD and normal control group were isolated from clinical tissues. Reverse transcription-quantitative polymerase chain reaction was used to evaluate the expression of miR-206 and SOX9 mRNA. Western blotting was used to measure the protein level of SOX9. A combination of Annexin V-fluorescein isothiocyanate flow cytometry was used to assess cell apoptosis. The association between miR-206 and SOX9 was detected using a luciferase reporter assay. miR-206 was overexpressed while SOX9 was downregulated in chondrocytes treated with DEX obtained from patients with LCPD. miR-206 targeted SOX9 to regulate its expression. Overexpression of miR-206 promoted cell apoptosis in TC28, while it was reversed by SOX9 overexpression. TC28 cells pretreated with DEX significantly promoted cell apoptosis, while cells transfected with miR-206 inhibitor significantly reversed the effect; however, downregulated SOX9 abolished the effects of miR-206 inhibitor. SOX9 mediated by miR-206 possibly contributed to the pathogenesis of LCPD. The results of the present study suggest that miR-206 and SOX9 function as important therapeutic targets for the future of clinical therapy.

Abstract
The Catsper channel is a sperm-specific, Ca2+-permeable, pH-dependent, and low voltage-dependent channel that is essential for the hyperactivity of sperm flagellum, chemotaxis towards the egg, capacitation and acrosome reaction. All of these physiological events require calcium entry into sperm cells. Remarkably, Catsper genes are exclusively expressed in the testis during spermatogenesis, and are sensitive to ion channel-induced pH change, such as NHEs, Ca2+ATPase, K+ channel, Hv1 channel and HCO3- transporters. Furthermore, the Catsper channel is regulated by some physiological stimulants, such as progesterone, cyclic nucleotides (e.g., cAMP, cGMP), zona pellucida (ZP) glycoproteins and bovine serum albumin (BSA). All of these factors normally stimulate Ca2+ entry into sperm through the Catsper channel. In addition, the Catsper channel may be a potential target for male infertility treatment or contraception. This review will focus on the structure, functions, regulation mechanisms and medicinal targets of the Catsper channel.

Abstract
Background The mammalian sperm-associated antigen 16 gene (Spag16) uses alternative promoters to produce two major transcript isoforms (Spag16L and Spag16S) and encode proteins that are involved in the cilia/flagella formation and motility. In silico analysis of both mouse and human SPAG16L promoters reveals the existence of multiple putative SOX5 binding sites. Given that the SOX5 gene encodes a 48-kDa transcription factor (S-SOX5) and the presence of putative SOX5 binding sites at the SPAG16L promoter, regulation of SPAG16L expression by S-SOX5 was studied in the present work. Results S-SOX5 activated human SPAG16L promoter activity in the human bronchial epithelia cell line BEAS-2B cells. Mutation of S-SOX5 binding sites abolished the stimulatory effect. Overexpression of S-SOX5 resulted in a significant increase in the abundance of SPAG16L transcripts whereas silencing of S-SOX5 by RNAi largely reduced the SPAG16L expression. Chromatin immunoprecipitation assays showed that S-SOX5 directly interacts with the SPAG16L promoter. Conclusion S-SOX5 regulates transcription of human SPAG16L gene via directly binding to the promoter of SPAG16L. It has been reported that expression of sperm-associated antigen 6 (SPAG6), encoding another axonemal protein, is activated by S-SOX5. Therefore, S-SOX5 may regulate formation of motile cilia/flagella through globally mediating expression of genes encoding axonemal proteins.

Quantification of CatSper1 expression in human spermatozoa and relation to functional parameters. Hum Reprod 2015; 30:1532-44.

Abstract
STUDY QUESTION Is CatSper1 expression in human spermatozoa related to semen parameter values and sperm functions? SUMMARY ANSWER CatSper1 expression is positively related to progressive and hyperactivated (HA) motility, [Ca(2+)]i responsiveness to progesterone but not the acrosome reaction (AR). WHAT IS KNOWN ALREADY The role of cationic channel of sperm (CatSper) in sperm functions is clear in animal models but less defined in human sperm cells. Current knowledge is mostly based on low specificity CatSper inhibitors showing agonistic and toxic effects on human spermatozoa and is thus of little help in clarifying the role of the CatSper channel in human sperm functions. STUDY DESIGN, SIZE, DURATION CatSper1 protein expression was evaluated in 115 men undergoing semen analysis for couple infertility. CatSper1 expression was related to routine semen parameters, motility kinematic parameters and basal and progesterone-stimulated [Ca(2+)]i and the AR. PARTICIPANTS/MATERIALS, SETTING, METHODS CatSper1 expression was evaluated (n = 85 normozoospermic, n = 30 asthenozoospermic patients) by immunofluorescence coupled to flow cytometry leading to quantitative measurement of the percentage of ejaculated sperm cells expressing the protein. Semen analysis was evaluated according to World Health Organization guidelines. Kinematic parameters were evaluated by a computer-aided sperm analysis system. [Ca(2+)]i was measured by a spectrofluorimetric method in fura-2-loaded spermatozoa. The AR was evaluated in live sperm cells by fluorescent-labeled lectin. MAIN RESULTS AND THE ROLE OF CHANCE CatSper1 protein expression in spermatozoa was reduced in asthenozoospermic men (mean ± SD: 53.0 ± 15.5%, n = 30 versus 67.9 ± 17.1% in normozoospermic, n = 85, P < 0.01) and was significantly correlated with progressive (r = 0.36, P < 0.001), total (r = 0.35, P < 0.001) and HA (r = 0.41, P < 0.005) motility. In addition to a higher percentage of spermatozoa not expressing CatSper1, asthenozoospermic men showed a large number of spermatozoa with immunofluorescent signal localized outside the principal piece compared with those in normozoospermia. A significant positive correlation was found between CatSper1 protein expression and the increase of [Ca(2+)]i in response to progesterone (r = 0.36, P < 0.05, n = 40) but not with basal [Ca(2+)]i. No correlation was found with the AR, either basal or in response to progesterone. LIMITATIONS, REASONS FOR CAUTION The study is partly descriptive. Furthermore, we cannot rule out the possibility that some round cells remain after a single round of 40% density gradient centrifugation or that this step may have removed some defective or slow swimming sperm, and therefore this preparation may not be representative of the entire sperm sample. Although our data suggest that CatSper1 may be a useful marker for infertility, and a possible contraceptive target, any clinical application is limited without further research. WIDER IMPLICATIONS OF THE FINDINGS Our results demonstrate an association of CatSper1 expression with human sperm progressive and HA motility and provide preliminary evidence that lack of expression or mislocalization of CatSper1 in spermatozoa may be involved in the pathogenesis of asthenozoospermia. However, mechanistic studies are needed to confirm that the correlations between CatSper1 expression and sperm functions are causative.
