Project description:The rete testis (RT) is a region of the mammalian testis which plays an important role in testicular physiology. The RT epithelium consists of cells sharing some well-known gene markers with supporting Sertoli cells (SCs). However, little is known about the differences in gene expression between these two cell populations. Here, we used fluorescence-activated cell sorting (FACS) to obtain pure cultures of neonatal RT cells and SCs and identified differentially expressed genes (DEGs) between these cell types using RNA sequencing (RNA-seq).

Project description:This dataset represents genes that are dysregulated in the postnatal day 12 (P12) mouse testis when ATRX is specifically inactivated in Sertoli cells (ScAtrxKO mice). The differentially expressed genes included in the dataset may play important roles in the testicular phenotypes observed in the ScAtrxKO mice, which were first reported in our previous work (Bagheri-Fam et al., 2011). In fetal ScAtrxKO mice, Sertoli cells undergo apoptosis due to cell cycle defects, resulting in smaller testes with reduced tubule volume. Adult ScAtrxKO mice show a wide range of spermatogenesis defects probably due to a failure of the dysfunctional ATRX protein to interact with the androgen receptor (AR). The chromatin remodeling protein ATRX is widely expressed in the human testis including Sertoli cells. In XY individuals, the loss of ATRX leads to ATR-X (alpha thalassemia, mental retardation, X-linked) syndrome associated with a wide range of genital abnormalities such as hypospadias, ambiguous genitalia, and small testes with reduced tubule volume. Our dataset contributes towards understanding the mechanism underlying ATRX regulation of testis development and spermatogenesis.

Project description:The study was designed to identify differences in the expressed transcriptome of the two pathological human testis sample groups compared to normal spermatogenesis samples, with the objective of discovering genes related to the pathological condition. Transcriptional differences in human testis biopsies collected from men with normal spermatogenesis (NSP, n=3; intact germ cells, clinical score - 10), spermatid arrest (SDA, n=2; contains somatic cells and germ cells up to round spermatids, clinical score – 4-5) and Sertoli cell-only (SCO, n=2; complete absence of germ cells, clinical score - 0) phenotypes were assessed by RNA sequencing. A total of over 49 million reads were generated in NSP samples, over 24 million reads in SDA samples, and over 13 million reads in SCO samples. Differentially expressed genes (DEG) were identified based on a mean minimum count => 5, FDR <= 0.05 and log2FC fold change of >0.585 or <-0.585. Genes differentially expressed in pathological groups SDA and SCO compared to NSP, and genes differentially expressed in between the two pathological groups SDA and SCO were filtered. The study discovered a number of significantly differentially expressed genes (DEG) between groups as follows: NSP vs SDA n=1,873; SDA vs SCO n= 4,017; and NSP vs SCO n=10,253. A number of genes (n=10) were selected for further analysis by qRT-PCR and the detection of the protein (n=2) localization in testis by immunohistochemistry.

Project description:Environmental toxicant induced epigenetic transgenerational inheritance has been shown to affect testis pathology and sperm count. Sertoli cells have an essential role in spermatogenesis by providing physical and nutritional support for developing germ cells. The current study was designed to further investigate the transgenerational epigenetic changes in the rat Sertoli cell epigenome that are associated with the onset of testis disease.

Project description:Although decades of research have established that androgen is essential for spermatogenesis, androgen’s mechanism of action remains elusive. This is in part because only a few androgen-responsive genes have been definitively identified in the testis. Here, we report that microRNAs—small, noncoding RNAs—are one class of androgen-regulated trans-acting factors in the testis. Specifically, by using androgen suppression and androgen replacement in mice, we show that androgen regulates the expression of several microRNAs in Sertoli cells. Our results reveal that several of these microRNAs are preferentially expressed in the testis and regulate genes that are highly expressed in Sertoli cells. Because androgen receptor–mediated signaling is essential for the pre- and postmeiotic germ cell development, we propose that androgen controls these events by regulating Sertoli/germ cell–specific gene expression in a microRNA-dependent manner.

The RT epithelium consists of cells sharing some well-known gene markers with supporting Sertoli cells (SCs). However, little is known about the differences in gene expression between these two cell populations. Here, we used fluorescence-activated cell sorting (FACS) to obtain pure cultures of neonatal RT cells and SCs and identified differentially expressed genes (DEGs) between these cell types using RNA sequencing (RNA-seq). We then compared our data with the RNA-seq data of other studies that examined RT cells and SCs of mice of different ages and generated a list of DEGs permanently upregulated in RT cells throughout testis development and in culture, which included 86 genes, and a list of 79 DEGs permanently upregulated in SCs. The analysis of studies on DMRT1 function revealed that nearly half of the permanent DEGs could be regulated by this SC upregulated transcription factor. We suggest that useful cell lineage markers and candidate genes for the specification of both RT cells and SCs may be present among these permanent DEGs.

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:MafB is a transcription factor acts as an important regulator of the development and differentiation of various organs and tissues. MafB is expressed in sertoli, leydig, and germ cells in adult mice testis. However, analysis of MafB cKO mice testis showed no dissruption of spermatogenesis or obvious abnormal structure. Thus, the exact function is unclear. We examined any change in the transcriptome profile of MafB-cKO Sertoli cells. Results of signaling pathway analysis of the downregulated genes was related to immune-function but not spermatogenesis.

Project description:MafB is a transcription factor acts as an important regulator of the development and differentiation of various organs and tissues. MafB is expressed in sertoli, leydig, and germ cells in adult mice testis. However, analysis of MafB cKO mice testis showed that MAFB is required for the initiation of the first spermatogenic wave but not the subsequent waves. We examined the transcriptome profile of MafB-cKO Sertoli cells during the first spermatogenic wave. Results of the down-regulated genes revealed that some genes are direct targets of MAFB since the presence of MARE sites in their promoters. Thus, they are candidates of maintaining MAFB function in sertoli cells.
