Project description:Immune privileged Sertoli cells (SC) survive when transplanted across immunological barriers and prolong the survival of co-transplanted allogeneic and xenogeneic cells in rodent models. However, the mechanism for this survival and protection remains unresolved. We have recently identified a mouse Sertoli cell line (MSC-1) that lacks some of the immunoprotective abilities associated with primary SC. The objective of this study was to compare the survival and gene expression profiles of primary SC and MSC-1 cells to identify factors or immune-related pathways potentially important for SC immune privilege. Primary SC or MSC-1 cells were transplanted as allografts to the renal subcapsular area of naïve BALB/c mice and cell survival was analyzed by immunohistochemistry. Additionally, transcriptome differences were investigated by microarray and pathway analyses. While primary SC were detected within the grafts with 100% graft survival throughout the 20-day study, MSC-1 cells w ere rejected between 11 and 14 days with 0% graft survival at 20 days post-transplantation. Microarray analysis identified 3198 genes that were differentially expressed with a ± 4-fold or higher level in primary SC. Cluster and pathway analyses indicate that the mechanism of SC immune privilege is likely complex with multiple immune modulators being involved such as immunosuppressive cytokines and complement inhibitors, lipid mediators for controlling inflammation, and junctional molecules that control leukocyte movement in and out of the immune privileged space. Further study of these immune modulators will increase our understanding of SC immune privilege and in the long-term lead to improvements in transplantation success. We conducted microarray and pathway analyses to identify genes and immune-related pathways differentially regulated by aggregated primary Sertoli cells and MSC-1 cell line. Aggregated 19 to 20-day mice primary Sertoli cells and MSC-1 cell line were used to determine the global transcriptome differences important for the survival and protection of transplanted cells.

Project description:Elevated palmitic acid, a most abundant saturated fatty acid, is a risk factor for obesity complications. Here, we report that palmitic acid impairs spermatogenesis by inducing abnormal palmitoylation in Sertoli cells. Firstly, we proposed a correlation between palmitic acid and spermatogenesis by reporting a significant elevation of serum palmitic acid levels in patients with dyszoospermia. In palmitic acid -treated mice, the blood-testis barrier was found to be disrupted, and decreased tight junction protein expression was observed in palmitic acid-treated Sertoli cells. Palmitic acid entered the endoplasmic reticulum and induced endoplasmic reticulum stress, resulting in damage to Sertoli cell barriers.

Project description:In MINUTE-ChIP, native chromatin is fragmented using Micrococcal nuclease, and subsequently blunted and ligated to double-stranded DNA adaptors that include a T7 RNA polymerase promoter and a sample barcode sequence. Finally, samples are combined and subsequent ChIP reactions are performed with the pooled samples. ChIP material is prepared into an Illumina-compatible library using linear amplification by virtue of T7 RNA polymerase, reverse transcription and a low-cycle library PCR amplification. Native MINUTE-ChIP is based on Mint-ChIP, developed by the Bernstein lab (van Galen et al., 2016; PMID: 26687680). We have introduce unique molecule (UMI) counting and paired-end mapping of the chromatin fragments to this method, which we then termed MINUTE-ChIP for multiplexed indexed unique molecule T7 amplification end-to-end sequencing. Here, we generate a standard curve for H3K27me3 and demonstrate that MINUTE-ChIP has a large linear dynamic range, thus MINUTE-ChIP quantitation is proportional to real quantities.

Project description:Sertoli cells provide nutrients and support for germ cell differentiation and maintain a stable microenvironment for spermatogenesis. Comprehensive identification of Sertoli cellular proteins is important in understanding spermatogenesis. In this study, we performed an integrative analysis of the proteome and phosphoproteome to explore the role of Sertoli cells in spermatogenesis. A total of 2912 and 753 proteins were identified from the proteome and phosphoproteome in Sertoli cells; 438 proteins were common to the proteome and phosphoproteome. In the proteome, ACTG1, ACTB, ACTA2, MYH9 were the most abundant proteins. Gene Ontology (GO) analysis indicated that most of the proteins are involved in the processes of localization, biosynthesis, gene expression, and transport. In addition, part of proteins related to Sertoli cell functions were also enriched. In the phosphoproteome, most of the proteins are involved in gene expression and the RNA metabolic process; the pathways mainly involve the spliceosome, mitogen-activated protein kinase（MAPK） signaling pathway, focal adhesion, and tight junctions. The pleckstrin homology-like domain is the most highly enriched protein domain in phosphoproteins. Cyclin-dependent kinases (CDKs) and protein kinases C (PKCs) were found to be highly active kinases in kinase-substrate network analysis. Ten proteins most closely related to network stability were found in the analysis of network interactions of proteins identified jointly by the phosphoproteome and proteome. Through immunohistochemistry and immunofluorescence verification of vimentin, it was found that there were localization differences between phosphorylated and non-phosphorylated vimentin in testicular tissue. This study is the first in-depth proteomic and phosphoproteomic analysis of the buffalo testicular Sertoli cells. The results provide insight into the role of Sertoli cells in spermatogenesis and provide clues for further study of male reproduction.

Project description:This study annotates the NGS reads in a Sertoli cell sncRNA library. In addition to known sncRNAs, we also identified numerous novel sncRNAs expressed by Sertoli cells. Our data suggest that the Sertoli cell sncRNA transcriptome predominantly consists of miRNAs, piRNA-like RNAs, tRNAs and snoRNAs. This study reports the first comprehensive annotation of the Sertoli cell sncRNA transcriptome.
