Project description:Establishment and maintenance of spermatogenesis need a complex process and vast regulatory network. There is growing evidence reveals that long noncoding RNAs (lncRNA) plays important role in regulating testicular development and spermatogenesis in a stage-specific way. We here report the identification of lncRNA LOC108635509 as key lncRNA regulator in black goat spermatogenesis. In the current study, we screened the transcriptomes (lncRNA and mRNA) of testicular from Guangxi black goats before puberty (3 days old, D3; 30 days old, D30), puberty (90 days old, D90) and postpuberty (180 days old, D180), and found there were 1211, 12180, 834 differential lncRNAs and 1196, 8838,269 differential mRNAs at the ages of D30 vs D3, D90 vs D30, and D180 vs D90. The expression pattern of differentially expressed (DE) lncRNAs indicated that D90 was a key node of lncRNAs participated in the regulation of testicular development and spermatogenesis in black goat. The of GO and KEGG analyses identified that DE lncRNAs and their target genes regulated spermatogenesis through MAPK, Ras, and PI3K-Akt signal pathways. Using cis- and trans-acting, 39 DE lncRNA-targeted genes were found to be enriched for male reproduction. Of these, LOC108635509, which specific expressed in testis and upregulated the expression levels at D90, was found participated in the regulation of testicular development through promoting the proliferation of SCs. Overall, this study provides new insight into the regulatory mechanisms that support spermatogenesis and testicular development in black goats.

Project description:Intensive research in past two decades has uncovered the presence and importance of noncoding RNAs (ncRNAs), which includes microRNAs (miRs) and long ncRNAs (lncRNAs). These two classes of ncRNAs interact to a certain extent, as some lncRNAs bind to miRs to sequester them. Such lncRNAs are collectively called 'competing endogenous RNAs' or 'miRNA sponges'. In this study, we screened for lncRNAs that may act as miRNA sponges using the publicly available data sets and databases. To uncover the roles of miRNA sponges, loss-of-function experiments were conducted, which revealed the biological roles as miRNA sponges. LINC00324 is important for the cell survival by binding to miR-615-5p leading to the de-repression of its target BTG2 LOC400043 controls several biological functions via sequestering miR-28-3p and miR-96-5p, thereby changing the expressions of transcriptional regulators. Finally, we also screened for circular RNAs (circRNAs) that may function as miRNA sponges. The results were negative at least for the selected circRNAs in this study. In conclusion, miRNA sponges can be identified by applying a series of bioinformatics techniques and validated with biological experiments. The expressions of miRs were examined in HEK-293 cells that were LINC00324- or LOC400043-silenced using siRNA.

Project description:Purpose: miRNAs, a member of the small RNA, play critical roles in the mammalian spermatogenesis. Spermatogonia was the foundation of spermatogenesis and valuable for the study of spermatogenesis. However, it is still not clear that the expression profiling of the miRNAs in spermatogonia of dairy goat. Methods: The CD49f was one of the surface markers for spermatogonia enrichment by MACS. Therefore, we used CD49f microbeads antibody to purify CD49f-positive and negative cells of dairy goat testicular cells by MACS (Magnetic Activated Cell Sorting), and then in-depth analyzed the miRNA expression in these cells using Illumina sequencing technology. Results: The results of miRNAs expression profiling in purified CD49f-positive and negative testicular cells showed that 933 were miRNAs upregulated in CD49f-positive cells and 916 were miRNAs upregulated in CD49f-negative cells with a 2-fold increase, respectively; some spermatogonial stem cells(SSCs) specific miRNAs and marker genes in testis had a higher level expression in CD49f-positive testicular cells, such as miR-221, miR-23a, miR-29b, miR-24, miR-29a, miR-199b, miR-199a, miR-27a, miR-21. Conclusions: our comparative miRNAome data provided some useful miRNAs profiling data of dairy goat spermatogonia cells and suggested CD49f could be used to enrich dairy goat spermatogonia-like cells, including SSCs. miRNA profiles of goat CD49f-positive and negative testicular cells were generated by deep sequencing, in triplicate, using Illumina GAIIx

Project description:The testis is an important reproductive organ in male mammals, serving as the site for spermatogenesis, androgen synthesis, and secretion. Non-coding RNAs (ncRNAs) plays an important regulatory role in various biological processes. However, the regulatory role of ncRNAs on yak testicular development and spermatogenesis is still largely unclear. In this study, the expression profiles of circRNA, miRNA, and mRNA in testicular tissues were compared between 6 months (Y6M), 18 months (Y18M), and 4 years old (Y4Y), with a significant difference in testicular development using RNA-seq. A total of 22 differentially expressed circRNAs (DE circRNAs), 69 differentially expressed miRNAs (DE miRNAs), and 64 differentially expressed mRNA (DE mRNAs) were detected in testicular samples of Y6M, Y18M, and Y4Y, respectively. Furthermore, GO and KEGG analysis results showed that the source genes of DE circRNAs, predicted target genes of DE miRNAs, and DE mRNAs concentrated on signaling pathways and GO terms that were related to sperm synthesis, vitality, and testicular development, such as cell cycle, Wnt signaling pathway, MAPK signaling pathway, GnRH signaling pathway, and spermatogenesis process. A circRNA-miRNA-mRNA network analysis revealed that some differentially expressed non-coding RNAs (DE ncRNAs) may be involved in testicular spermatogenesis, including miR-574, miR-449a, CDC42, CYP11A1 and et al. At the same time, there are various circRNA-miRNA interaction pairs. This study provides a deep understanding of the regulatory network of ncRNA regulation in yak testicular development, providing data support for further elucidating the molecular mechanisms of yak testicular development.

Project description:Triptolide has been shown to exert various pharmacological effects on systemic autoimmune diseases and cancers. However, its severe toxicity, especially reproduction toxicity, prevents wide clinical use for those people with fertility needs. Noncoding RNAs including lncRNAs and cicrRNAs are regulatory molecules that mediate a wide variety of physiological activities, which are critical for spermatogenesis, and their dysregulation might lead to male infertility. However, whether they are involved in triptolide-induced reproduction toxicity is fully unknown. Here, after exposure of mice to triptolide for 35 day, the total RNAs were used to investigate lncRNAs/cicrRNAs/mRNAs expression profiles by strand-specific RNA sequencing at the transcriptome level to help determine any RNA-related mechanisms in triptolide-induced toxicity. The results showed that triptolide significantly decreased the testicular weight, damaged testis and sperm morphology, reduced sperm motility and density. Furthermore, there's a remarkable deformity in sperm head and tail in triptolide-exposed mice. At the transcriptome level, the triptolide-treated mice exhibited aberrant expression profiles for lncRNAs/cicrRNAs/mRNAs, many of them were dysregulated. Gene ontology and pathway analyses revealed that the functions of differentially expressed lncRNA targets, cicrRNAs cognate genes and mRNAs were closely linked with many processes involved in spermatogenesis. Additionally, many newly identified lncRNAs /cicrRNAs displayed inducible expression, suggesting that they might be good candidate markers for triptolide-induced male reproductive toxicity. This study gives us an insight into understanding the reproductive system toxicity of triptolide and reminds us to strengthen the research on increasing efficacy and decreasing toxicity of triptolide.

Project description:Purpose: This study aimed to explore the differential expression profiles of exosomal lncRNAs and evaluated their potential utility in the accurate diagnosis of LAA stroke. Methods: LncRNA profiles of exosomes in large artery atherosclerosis stroke and controls were generated by high-throughput sequencing. The sequence reads that passed quality filters were analyzed at the transcript isoform level with Hisat2, Trapnell, STAR. qRT–PCR validation was performed using TaqMan and SYBR Green assays. Results: A total of 1020 differentially expressed lncRNAs were identified in LAA stroke patients. GO and KEGG pathway analyses indicated that their target genes are involved in atherosclerosis-related pathways, including inflammation, cell adhesion, and cell migration. 8 exosomal lncRNAs were confirmed with qRT–PCR.The result showed that the expression trend of differential expressed lncRNAs in validation was consistent with RNA-seq.Conclusion: Our study showed the differential expression of lncRNAs in plasma exosomes and presented related diagnostic potential for LAA stroke for the first time. The results suggested that exosomal lncRNA could be potential diagnostic tools in LAA stroke. Circular RNAs (circRNAs), novel endogenous noncoding RNAs, play diverse roles in ischemic stroke. Recently, the abundance and stability of circRNAs in exosomes have been identified. However, a comprehensive analysis of exosomal circRNAs in large artery atherosclerotic (LAA) stroke has not yet been reported. We performed RNA sequencing (RNA-Seq) to comprehensively identify differentially expressed exosomal circRNAs in five paired LAA and normal controls. RNA-Seq identified a total of 462 circRNAs in peripheral exosomes; there were 25 differentially expressed circRNAs among them. Additionally, circRNA competing endogenous RNA (ceRNA) network and translatable analysis revealed the potential functions of the exosomal circRNAs in LAA progression. Two ceRNA pathways involving 5 circRNAs, 2 miRNAs, and 3 mRNAs were confirmed by qRT-PCR. In the validation cohort, receiver operating characteristic (ROC) curve analysis identified two circRNAs as possible novel biomarkers, and a logistic model combining two and four circRNAs increased the area under the curve compared with the individual circRNAs.

Project description:Spermatogenesis is a complex cell differentiation process that includes marked genetic, cellular functional and structural changes. It requires tight regulation, since disturbances in any of the spermatogenic stages would lead to fertility deficiencies. In order to increase our knowledge of signal transduction during sperm development, we carried out a large-scale identification of the phosphorylation events that occur in the human gonad. Metal oxide affinity chromatography using TiOx combined with LC-MS/MS was conducted to profile the phosphoproteome of human testes with full spermatogenesis. A total of 8187 phosphopeptides derived from 2661 proteins were identified, resulting in the most complete report of human testicular phosphoproteins to date. Phosphorylation events were enriched in proteins functionally related to spermatogenesis, as well as to highly active processes in the male gonad, such as transcriptional and translational regulation, cytoskeleton organization, DNA packaging, cell cycle and apoptosis. Moreover, 174 phosphorylated kinases were identified. The most active and abundant human protein kinases in the testis were predicted both by the phosphorylation status of the kinase activation loop and the number of phosphopeptide spectra identified. The potential function of two of those kinases, cyclin-dependent kinase 12 (CDK12) and p21-activated kinase 4(PAK4), has been explored by protein-protein interaction analysis, immunodetection in human and mouse testicular tissue, and functional assay in a human embryonal carcinoma cell line. The co-localization of CDK12 with Golgi markers and probably pro-acrosomal vesicles suggests a potential crucial role of this protein kinase in sperm formation. PAK4 expression has been found limited to human spermatogonia, and a role in embryonal carcinoma cell response to apoptosis has been observed. Together, our data confirm that phosphoregulation by protein kinases is highly active in sperm differentiation, and open a window to detailed characterization and validation of potential targets for the development of drugs modulating male fertility, and tumor behavior.
