Abstract
BACKGROUND Testicular cancer is fairly rare but can affect fertility in adult males. Leucine-rich repeats- and WD repeat domain-containing protein 1 (LRWD1) is a sperm-specific marker that mainly affects sperm motility in reproduction. Our previous study demonstrated the impact of LRWD1 on testicular cancer development; however, the underlying mechanisms remain unclear. METHODS In this study, various plasmids associated with LRWD1 and miR-320a manipulation were used to explore the roles and regulatory effects of these molecules in NT2D1 cellular processes. A Dual-Glo luciferin-luciferase system was used to investigate LRWD1 transcriptional activity, and qRT-PCR and western blotting were used to determine gene and protein expression. RESULTS The results suggested that miR-320a positively regulated LRWD1 and positively correlated with NT2D1 cell proliferation but negatively correlated with cell migration and invasion ability. In addition, the miRNA-ribonucleoprotein complex AGO2/FXR1 was shown to be essential in the mechanism by which miR-320a regulates LRWD1 mRNA expression. As miR-320a was required to regulate LRWD1 expression through the AGO2 and FXR1 complex, eEF2 and eLF4E were also found to be involved in miR-320a increasing LRWD1 expression. Furthermore, miR-320a and LRWD1 were responsive to oxidative stress, and NRF2 was affected by the presence of miR-320a in response to ROS stimulation. CONCLUSIONS This is the first study showing the role of miR-320a in upregulating the testicular cancer-specific regulator LRWD1 and the importance of the AGO2/FXR1 complex in miR-320a-mediated upregulation of LRWD1 during testicular cancer progression.

Abstract
High-resolution ribosome fractionation and low-input ribosome profiling of bovine oocytes and preimplantation embryos has enabled us to define the translational landscapes of early embryo development at an unprecedented level. We analyzed the transcriptome and the polysome- and non-polysome-bound RNA profiles of bovine oocytes (germinal vesicle and metaphase II stages) and early embryos at the two-cell, eight-cell, morula and blastocyst stages, and revealed four modes of translational selectivity: (1) selective translation of non-abundant mRNAs; (2) active, but modest translation of a selection of highly expressed mRNAs; (3) translationally suppressed abundant to moderately abundant mRNAs; and (4) mRNAs associated specifically with monosomes. A strong translational selection of low-abundance transcripts involved in metabolic pathways and lysosomes was found throughout bovine embryonic development. Notably, genes involved in mitochondrial function were prioritized for translation. We found that translation largely reflected transcription in oocytes and two-cell embryos, but observed a marked shift in the translational control in eight-cell embryos that was associated with the main phase of embryonic genome activation. Subsequently, transcription and translation become more synchronized in morulae and blastocysts. Taken together, these data reveal a unique spatiotemporal translational regulation that accompanies bovine preimplantation development.

Basic Clin Androl 2021; 31:12.

Abstract
BACKGROUND Sperm growth and maturation are correlated with the expression levels of Leucine-rich repeat and WD repeat-containing protein 1 (LRWD1), a widely expressed protein in the human testicles. The decrease in LRWD1 cellular level was linked to the reduction in cell growth and mitosis and the rise in cell microtubule atrophy rates. Since DNA methylation has a major regulatory role in gene expression, this study aimed at exploring the effect of the modulation of DNA methylation on LRWD1 expression levels. RESULTS The results revealed the presence of a CpG island up of 298 bps (- 253 ~ + 45) upon LRWD1 promoter in NT2/D1 cells. The hypermethylation of the LRWD1 promoter was linked to a reduction in the transcription activity in NT2/D1 cells, as indicated by luciferase reporter assay. The methylation activator, floxuridine, confirmed the decrease in the LRWD1 promoter transcriptional activity. On the other hand, 5-Aza-2'-deoxycytidine (5-Aza-dc, methylation inhibitor), significantly augmented LRWD1 promoter activity and the expression levels of mRNA and proteins. Furthermore, DNA methylation status of LRWD1 promoter in human sperm genomic DNA samples was analyzed. The results indicated that methylation of LRWD1 promoter was correlated to sperm activity. CONCLUSIONS Thus, the regulation of LRWD1 expression is correlated with the methylation status of LRWD1 promoter, which played a significant role in the modulation of spermatogenesis, sperm motility, and vitality. Based on these results, the methylation status of LRWD1 promoter may serve as a novel molecular diagnostic marker or a therapeutic target in males' infertility.

Abstract
Multiple morphological abnormalities of the sperm flagella (MMAF) are a major cause of asthenoteratozoospermia. We have identified protease serine 50 (PRSS50) as having a crucial role in sperm development, because Prss50-null mice presented with impaired fertility and sperm tail abnormalities. PRSS50 could also be involved in centrosome function because these mice showed a threefold increase in acephalic sperm (head-tail junction defect), sperm with multiple heads (spermatid division defect) and sperm with multiple tails, including novel two conjoined sperm (complete or partial parts of several flagellum on the same plasma membrane). Our data support that, in the testis, as in tumorigenesis, PRSS50 activates NFκB target genes, such as the centromere protein leucine-rich repeats and WD repeat domain-containing protein 1 (LRWD1), which is required for heterochromatin maintenance. Prss50-null testes have increased IκκB, and reduced LRWD1 and histone expression. Low levels of de-repressed histone markers, such as H3K9me3, in the Prss50-null mouse testis may cause increases in post-meiosis proteins, such as AKAP4, affecting sperm formation. We provide important insights into the complex mechanisms of sperm development, the importance of testis proteases in fertility and a novel mechanism for MMAF.

Abstract
Background: Asthenozoospermia, one of the most common causes of male infertility, is a complicate multifactorial pathological condition that genetic factors are involved in. However, the epigenetic signature and mechanism of asthenozoospermia still remain limited. Our study aimed to confirm the key microRNAs (miRNAs) and genes in asthenozoospermia and demonstrate the underlying epigenetic regulatory mechanisms. Methods: We screened out and pooled previous studies to extracted potential differentially expressed miRNAs (DEMs). GSE22331 and a published profile dataset were integrated to identify differentially expressed genes (DEGs). Pathway and gene ontology analysis were performed using DAVID. A protein-protein network (PPI) was constructed using STRING. The target genes of DEMs were predicted using TargetScan and the miRNA-mRNA network was built. Results: We reported 3 DEMs and 423 DEGs by pooling included dataset and published studies. Pathway analysis showed that these DEGs might participate in signaling pathways regulating pluripotency of stem cells, Wnt signaling pathway and Notch signaling pathway. 25 hub genes were identified, and the most significant gene was BDNF. We screened out the overlapped DEGs between the predicted target genes of 3 DEMs and the 423 DEGs. Finally, a potential miRNA-mRNA regulatory network was constructed. Conclusion: This study firstly pooled several published studies and a GEO dataset to determine the significance of potential miRNAs and genes, such as miR-374b, miR-193a, miR-34b, BDNF, NTRK2, HNRNPD and EFTUD2 in regulating asthenozoospermia and underscore their interactions in the pathophysiological mechanism. Our results provided theoretical basis and new clues for potential therapeutic treatment in asthenozoospermia. Validations in vivo and in vitro are required in future studies.

Abstract
Platinum-based drugs such as cisplatin are widely used in combination chemotherapy for non-small cell lung cancer (NSCLC) owing to their high clinical response rate; however, acquired resistance to cisplatin is eventually inevitable. Circular RNAs (circRNAs) are involved in the development of diverse types of cancers, but their connection to cisplatin-resistance in NSCLC has not been studied. In the present study, two cisplatin-resistant NSCLC cell lines (A549/DDP and PC9/DDP) were established by gradually increasing concentrations of cisplatin in the media. The resulting cell lines possessed high resistance to cisplatin and strong proliferation, migration, and colony formation abilities compared to the parental cells. Microarray analysis identified 19,161 circRNAs that were dysregulated in cisplatin-resistant cell lines (fold change abs>2), including 11,915 up-regulated and 7246 down-regulated circRNAs. The expression of the top five up-regulated and down-regulated circRNAs was validated using real-time quantitative polymerase chain reaction. A circRNA-micro RNA (miRNA) network of the top 20 dysregulated circRNAs and their predicted miRNAs was constructed using Cytoscape. Gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses revealed that the host genes of the identified circRNAs were involved in the regulation of MAP kinase kinase kinase kinase activity, 6-phosphofructo-2-kinase activity, focal adhesion, ErbB signaling, and ECM-receptor interactions, which may contribute to cisplatin resistance in NSCLC. In summary, this is the first report on circRNA profiling in cisplatin-resistant NSCLC cells and it provides new potential targets for the reversal of cisplatin resistance in NSCLC.

Abstract
Septins play important roles in regulating development and differentiation. Septin 7 (SEPT7) is a crucial component in orchestrating the septin core complex into highly ordered filamentous structures. Here, we showed that genetic depletion of SEPT7 or treatment with forchlorfenuron (FCF; a compound known to affect septin filament assembly) led to reduced the S phase entry in cell models and zebrafish embryos. In addition to colocalizing with actin filaments, SEPT7 resided in the centrosome, and SEPT7 depletion led to aberrant mitotic spindle pole formation. This mitotic defect was rescued in SEPT7-deficient cells by wild-type SEPT7, suggesting that SEPT7 maintained mitotic spindle poles. In addition, we observed disorganized microtubule nucleation and reduced cell migration with SEPT7 depletion. Furthermore, SEPT7 formed a complex with and maintained the abundance of p150glued , the component of centriole subdistal appendages. Depletion of p150glued resulted in a phenotype reminiscent of SEPT7-deficient cells, and overexpression of p150glued reversed the defective phenotypes. Thus, SEPT7 is a centrosomal protein that maintains proper cell proliferation and microtubule array formation via maintaining the abundance of p150glued .

Abstract
Introduction Human gestational choriocarcinoma, a type of gestational trophoblastic disease, occurs after miscarriage, abortion, ectopic pregnancy, or molar pregnancy. Despite recent advances in the mechanism of anticancer drugs that induce human gestational choriocarcinoma apoptosis or block its growth, new therapeutic approaches are needed to be established. Cordycepin is an active anti-cancer component extracted from Cordyceps sinensis. It prevents cell proliferation both in vitro and in vivo. Materials and Methods Here, we examined cell growth by counting cell numbers, and performing a flow cytometry assay and EdU incorporation assay. Centrosome and cytoskeleton-related structures were observed by immunofluorescence assay. The DNA damage-related signaling was examined by Western blot assay. Results Here, we showed that cordycepin inhibited human gestational choriocarcinoma cell proliferation and induced cell death. In addition, treatment with cordycepin activated DNA-PK and ERK, thus inducing centrosome amplification and aberrant mitosis. These amplified centrosomes also disrupted microtubule arrays and actin networks, thus leading to defective cell adhesion. Furthermore, cordycepin induced autophagy for triggering cell death. Conclusion Thus, our study demonstrates that cordycepin inhibits cell proliferation and disrupts the cytoskeleton by triggering centrosome amplification.

[PMID: 31205500 PMCID: PMC6535720 DOI: 10.1177/1758835919846372] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2018] [Accepted: 03/13/2019] [Indexed: 01/04/2023] Open
Abstract
Background: The aim of this study was to investigate the contributions of FAM84B in prostate tumorigenesis and progression. Methods: A FAM84B mutant with deletion of its HRASLS domain (ΔHRASLS) was constructed. DU145 prostate cancer (PC) cells stably expressing an empty vector (EV), FAM84B, or FAM84B (ΔHRASLS) were produced. These lines were examined for proliferation, invasion, and growth in soft agar in vitro. DU145 EV and FAM84B cells were investigated for tumor growth and lung metastasis in NOD/SCID mice. The transcriptome of DU145 EV xenografts (n = 2) and DU145 FAM84B tumors (n = 2) was determined using RNA sequencing, and analyzed for pathway alterations. The FAM84B-affected network was evaluated for an association with PC recurrence. Results: FAM84B but not FAM84B (ΔHRASLS) increased DU145 cell invasion and growth in soft agar. Co-immunoprecipitation and co-localization analyses revealed an interaction between FAM84B and FAM84B (ΔHRASLS), suggesting an intramolecular association among FAM84B molecules. FAM84B significantly enhanced DU145 cell-derived xenografts and lung metastasis. In comparison with DU145 EV cell-produced tumors, those generated by DU145 FAM84B cells showed a large number of differentially expressed genes (DEGs; n = 4976). A total of 51 pathways were enriched in these DEGs, which function in the Golgi-to-endoplasmic reticulum processes, cell cycle checkpoints, mitochondrial events, and protein translation. A novel 27-gene signature (SigFAM) was derived from these DEGs; SigFAM robustly stratifies PC recurrence in two large PC populations (n = 490, p = 0; n = 140, p = 4e−11), and remains an independent risk factor of PC recurrence after adjusting for age at diagnosis, Gleason scores, surgical margin, and tumor stages. Conclusions: FAM84B promotes prostate tumorigenesis through a complex network that predicts PC recurrence.

Cloning of a new testis-enriched gene C4orf22 and its role in cell cycle and apoptosis in mouse spermatogenic cells. Mol Biol Rep 2019; 46:2029-2038. [PMID: 30820741 DOI: 10.1007/s11033-019-04651-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2018] [Accepted: 01/24/2019] [Indexed: 01/29/2023]
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.

Kuo PL, Tseng JY, Chen HI, Wu CY, Omar HA, Wang CY, Cheng HY, Hsu CC, Fu TF, Teng YN. Identification of SEPTIN12 as a novel target of the androgen and estrogen receptors in human testicular cells. Biochimie 2018; 158:1-9. [PMID: 30513371 DOI: 10.1016/j.biochi.2018.11.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2018] [Accepted: 11/29/2018] [Indexed: 11/16/2022]
Abstract
SEPTIN12 (SEPT12) is a testis-enriched gene that is downregulated in the testis of infertile men with severe spermatogenic defects. While SEPT12 is involved in spermatogenic failure and sperm motility disorder, SEPT12 transcriptional regulation is still unknown. Here we report the promoter region of SEPT12 as a 245 bp segment upstream of the transcription start site. One androgen receptor (AR) and two estrogen receptor α (ERα) binding sites in this region were initially identified by bioinformatics prediction and confirmed by chromatin immunoprecipitation assay. Truncated ERα or AR binding sites decreased the promoter activity, which indicated that the ERα and AR are essential for the SEPT12 promoter. On the other hand, the promoter activity was enhanced by the treatment with 17β-estradiol (E2) and 5α-dihydrotestosterone (5α-DHT). Thus, one androgen and two estrogen hormone responsive elements located in the promoter of SEPT12 gene can regulate SEPT12 expression. Two single nucleotide polymorphisms (SNPs), rs759992 T > C and rs3827527 C > T, were observed in the SEPT12 gene promoter region and were able to decrease the promoter activity. In conclusion, the current work identified the promoter of the human SEPT12 gene and provided key evidence about its transcriptional regulation via E2 and 5α-DHT. Since SEPT12 has an important role in spermatogenesis, SEPT12 expression analysis can be developed as a potential tool for the assessment of environmental or food pollution by hormones or for the evaluation of the risk of endocrine-disrupting chemicals (EDCs) in general.
