SWATH-MS analysis of nuclear and cytoplasmic fractions of rat Sertoli cells

Project description:The Sertoli cells (Sc) of 5 days (infant) and 12 days (pubertal) old rat were isolated and cultured in triplicates. Nuclear and cytoplasmic fractionation was done for both the cases. All the four protein fractions (nuclear and cytoplasm of infant and pubertal Sc) were anaysed using Lc-MS/MS. SWATH analysis was done for all the four samples in biological and technical replicates. The objective was to quantity the proteins of all the samples with respect to each other at whole proteome level.

Enhanced early-life nutrition upregulates cholesterol biosynthetic gene expression and Sertoli cell maturation in testes of pre-pubertal Holstein bulls

Project description:Pre-pubertal Holstein bull calves fed a higher plane of nutrition had larger testes, earlier puberty, higher serum LH, testosterone and greater sperm production potential than those fed a restricted diet. In addition, pre-pubertal calves fed a high-nutrition diet had higher IGF-I and more proliferating and differentiating Sertoli cells much earlier in life, compared to those fed normal or low-nutrition diets. The objective was to determine changes in mRNA expression of genes in the testes of bulls fed either a high or low pre-pubertal diet. Holstein bull calves maintained on either a high (20% crude protein (CP) and 71.6% Total Digestible Nutrients (TDN)) or low (12% CP and 64.4% TDN) diet from 2 wk of age, were castrated at 8, 16, 24 and 32 wk and testicular mRNA extracted and sequenced. Differential expression of genes mainly occurred at 16 and 24 wk, with minor changes detected at 32 wk. At 16 wks, functional analysis of DE mRNA with DAVID revealed the common biological processes enriched to be "cholesterol" and "fatty acid biosynthesis" with majority of the genes including HMGCR, HMGCS1, HSD17 being upregulated in high-diet bulls (P<0.05). Major pathways enriched at 16 wks were "cholesterol biosynthesis", "steroid metabolism" and "activation of gene expression by Sterol regulatory element-binding protein (SREBP)" (P<0.05). Mature Sertoli cell marker Connexin 43, was upregulated at 16 wk, whereas an immature Sertoli cell marker, AMH was downregulated at 24 wk, in the high-diet group. Network analysis using IPA, revealed an indirect interaction between insulin family receptor and most upregulated cholesterol biosynthesis genes, implying regulation of testicular function. Thus, enhanced pre-pubertal nutrition in Holstein bulls enhanced testicular cholesterol/steroid biosynthesis and Sertoli cell maturation to promote early reproductive development.

The Fetal and Infant Human Testis Cell Atlas via Single-cell RNA-seq

Project description:Human testis development in prenatal life involves complex changes in germline and somatic cell identity. To better understand, we profiled and analyzed ~32,500 single-cell transcriptomes of testicular cells from embryonic, fetal and infant stages. Our data shows that at 6-7 weeks post-fertilization as the testicular cords are established, the Sertoli and interstitial cells originate from a common heterogeneous progenitor pool, which then resolves into fetal Sertoli cells (expressing tube-forming genes) or interstitial cells (including Leydig-lineage cells expressing steroidogenesis genes). Almost ten weeks later, beginning at 15-16 weeks post-fertilization, the male primordial germ cells exit mitosis, downregulate pluripotent transcription factors and transition into cells that strongly resemble the ‘State 0’ spermatogonia originally defined in the infant and adult testes. Therefore, we termed these fetal spermatogonia ‘State f0’. Taken together, we reveal multiple insights into the coordinated and temporal development of the embryonic, fetal and postnatal male germline together with the somatic niche.

Gene expression in follicle-stimulating hormone-treated rat Sertoli cells

Project description:Spermatogenesis requires the presence of functional somatic Sertoli cells in the seminiferous tubules of the testis. Sertoli cells provide support and factors necessary for the successful progression of germ cells into spermatozoa. Sertoli cells are regulated to a large degree by the glycoprotein hormone FSH, which is required for the testis to acquire full size and spermatogenic capacity. Signaling events initiated by the binding of FSH to its receptor lead to an alteration of Sertoli cell gene expression. To characterize the changes in gene expression in FSH-treated Sertoli cells, we used the mRNA from these cells to screen Affymetrix U34A rat GeneChip oligonucleotide microarrays. Sertoli cells from 20-d-old rats were cultured in the presence of 25 ng/ml ovine FSH. At 0, 2, 4, 8, and 24 h after the addition of FSH, total RNA was purified and used to prepare biotinylated target, which was hybridized to the U34A rat microarray containing approximately 9000 rat genes. Analysis identified 100-300 transcripts at each time point that were up-regulated or down-regulated by 2-fold or greater. Genes previously reported to be FSH or cAMP regulated in rat Sertoli cells were identified, in addition to numerous genes not reported to be expressed or FSH regulated in Sertoli cells. The expression patterns of five of these genes, encoding nerve growth factor inducible gene B, PRL-1, PC3 nerve growth factor-inducible antiproliferative putative secreted protein, diacylglycerol acyltransferase, and an expressed sequence tag, in FSH- and N,O'-dibutyryl cAMP-treated rat Sertoli cells were confirmed and characterized by Northern blot analysis. Thus, we have begun to define the transcriptome induced and repressed by FSH in rat Sertoli cells, and we have generated datasets of genes available for further analysis in regard to spermatogenesis and Sertoli cell signaling.

Enhanced pre-pubertal nutrition upregulates mitochondrial function in the testes and sperm of post-pubertal Holstein bulls

Project description:Recent studies have documented the profound impact of pre-pubertal nutrition on reproductive performance in bulls. Previously, a high plane of nutrition during calfhood (2-30 wk) in beef and dairy bulls hastened puberty explained by an increase in the level of reproductive hormones (LH, testosterone and IGF-I) pre-pubertally, compared to bulls fed less than recommended amounts of energy and protein with no apparent effect on sperm function evaluated by traditional techniques. In addition, upregulated steroid biosynthesis and Sertoli cell maturation was identified in the testicular tissue of high diet bulls at 16 and 24 weeks, respectively. The objective of this study was to evaluate the post- pubertal testes for responses to high (20.0% CP, 67.9% TDN), medium (17.0% CP, 66.0% TDN) and low (12.2% CP, 62.9% TDN) diets fed from 2-30 wk of life. Based on RNA sequencing data, 497 genes were differentially expressed in high vs low diet and 2961 genes in high vs medium diet (P<0.1). According to KEGG analysis, oxidative phosphorylation and ribosome pathways were upregulated in the high diet group (vs medium and low) with majority of the upregulated genes encoding for essential subunits of complex I, III, IV and V of OXYPHOS pathway. In addition, mitochondrial translation, mitotic nuclear division and cell division were enriched in the high vs medium diet group. Supporting the above, the percentage of sperm exhibiting loss of mitochondrial function was lower in the high diet compared to the medium diet (P<0.1). Thus, enhanced early life nutrition upregulated mitochondrial function in both the testes and sperm of post-pubertal Holstein bulls.

Transcriptome of normal mammary glands of Sprague-Dawley rats at six stages of development: pre-pubertal, peri-pubertal, pubertal, lactation, adult parous and age-matched nulliparous

Project description:There is a lack of systematic investigations of large-scale transcriptome patterns associated with normal breast development. Herein, we profiled whole-transcriptome (by microarrays) of normal mammary glands in female Sprague-Dawley rats, an animal model widely used in breast cancer research, across six distinctive developmental stages – pre-pubertal, peri-pubertal, pubertal, lactation, and adult parous and age-matched nulliparous.

Single-cell analysis of developing and azoospermia human testicles reveals central role of Sertoli cells

Project description:Non -obstructive azoospermia (NOA) affects 1% of men. However, the unknowns of NOA pathogenesis and even normal spermatogenic microenvironment establishment severely limit the clinical efficacy of NOA treatment. We profiled > 80,000 human testicular single-cell transcriptomes from 10 healthy donors spanning the range from infant to adult and 7 NOA patients. Sertoli cells, which form the scaffold in the testicular microenvironment, exhibited the most obvious damages in NOA patients. We identified roadmap of Sertoli cell maturation. Notably, Sertoli cells of patients with congenital causes (Klinefelter syndrome and Y chromosome microdeletions) are mature but with abnormal immune response, while the cells in idiopathic NOA (iNOA) are basically physiologically immature. Furthermore, inhibition of Wnt signaling promotes the maturation of Sertoli cells from iNOA patients, allowing these cells to regain their ability to support germ cell survival. We provide a novel perspective for the development of diagnostic methods and therapeutic targets for NOA.
