Project description:The effects of Gata4 inhibition on global gene expression in TM4 Sertoli cells was analyzed. Using microarray analysis we identified a set of genes that are downregulated or upregulated following siRNA-mediated silencing of Gata4 in the murine Leydig tumor cell line mLTC-1. Among the downregulated genes were enzymes of the androgen biosynthetic pathway. TM4 cells were transfected with non-targeting (NT) siRNA and Gata4 siRNA respectively. 72h post transfection cells were lysed and RNA was extracted. n=3 of each sample group; control samples are samples 3-6 (TM4 cells treated with non-targeting siRNA)

Project description:Vitamin C (ascorbic acid, AA), as essential micro-nutrient and antioxidant, can affect multiple cellular processes. Previously, we showed that Vitamin C supplement could promote the proliferation and suppress apoptosis of porcine Sertoli cells, via modulating the global nucleic acid methylation levels to alter transcriptome and proteomics. Due to the differences between pig and rodent species, here we investigated the effects of Vitamin C on mouse TM4 Sertoli cells. Vitamin C (250µM) treatment of mouse TM4 Sertoli cells for 36h could significantly increase cell viability, promote cell proliferation and decrease the cell percentage with early apoptosis. Vitamin C (250µM, 36h) also significantly decreased ROS level, elevated mitochondrial function, altered the levels of nucleic acid N6-methylation (m6A) and modified the levels of histone H3 trimethylation (H3K4me3, H3K9Me3 and H3K36me3) of mouse TM4 Sertoli cells. Vitamin C (250µM, 36h) promoted the secretion of anti-müllerian hormone and Estrodiol, but decreased lactate metabolite in mouse TM4 Sertoli cells. RNA-seq identified 112 differentially expressed genes (DEGs) (74 up- and 38 down-regulated) (P≤0.05, |log2Fold Change|≥1) as induced by Vitamin C in mouse TM4 Sertoli cells. Gene enrichment analysis found multiple significantly enriched biological terms or pathways, including GO terms of regulation of response to biotic stimulus, homeostasis of number of cells, positive regulation of tumor necrosis factor production, GTPase activity, calmodulin binding etc., and KEGG signal pathways of calcium signal pathway, cGMP-PKG signaling pathway, steroid biosynthesis, arginine biosynthesis etc. 9 DEGs were selected for RT-qPCR validation and 8 of them showed the change trend consistent to RNA-seq. Taken together, Vitamin C (250µM, 36h) could modulate the functions of mouse TM4 Sertoli cells, through modifying the transcriptome to affect multiple signal pathways.

Project description:Phthalate plasticizers are being phased out of consumer products because of their endocrine disrupting properties. This has resulted in a need to find safe alternatives that can plasticize polyvinyl chloride (PVC) while being inexpensive and biodegradable. We aim to study the toxicogenomic profile of mono-(2-ethylhexyl) phthalate (MEHP, the active metabolite of bis(2-ethylhexyl) phthalate, DEHP), the commercial plasticizer 1,2-cyclohexane dicarboxylic acid diisononyl ester (DINCH), and three plasticizers in development (1,4 butanediol dibenzoate (BDB), dioctyl succinate (DOS), and dioctyl maleate (DOM)) using the immortalized TM4 Sertoli cell line.

Using microarray analysis we identified a set of genes that are downregulated or upregulated following siRNA-mediated silencing of Gata4 in the murine Sertoli cell line TM4. Among the downregulated genes were regulators of blood-testtis barrier function and lactate metabolism. TM4 cells were transfected with non-targeting (NT) siRNA and Gata4 siRNA respectively. 72h post transfection cells were lysed and RNA was extracted.

Project description:In this study, we aim to figure out if Sertoli cells released exosomes can regulate the survival and steroidogenesis of Leydig cells. We found Sertoli cells released exosomes can cross the blood-testis barrier, deliver their contents into the Leydig cells, and promote the survival of Leydig cells through CCL20.

Each sample contains four biological replicates except for DOS that contains three. The control is 1.0% DMSO as this was the vehicle used to solubilize the test compounds.

Project description:Analysis of Sertoli and Leydig cell “translatome” utilizing an in vivo ribosome tagging strategy (RiboTag) that allows a detailed and physiologically relevant characterization of the polysome-associated mRNAs in vivo. Although progress has been made in the identification of specific transcripts that are translated in Sertoli and Leydig cells and their response to hormones, efforts to expand these studies have been restricted by technical hurdles. Our analysis identified all previously characterized Leydig and Sertoli cell-specific markers and identified in a comprehensive manner novel markers of Leydig and Sertoli cells; the translational response of these two cell types to gonadotropins or testosterone was also investigated.

Leydig cell-specific (Cyp17iCre: RiboTag) and Sertoli cell-specific (AMH-Cre: RiboTag) RiboTag mice were obtained by crossing RiboTag homozygous mice with Cyp17iCre or AMH-Cre mice. For in vivo LH treatment experiments, mice were injected with the GnRH antagonist acyline for 4 days before a single injection of purified human LH. After treatment, testes were homogenized and polysomes were immunoprecipitated by utilizing an anti-HA antibody. RNA was extracted, labelled, and hybridized to Mouse Gene ST 1.0 arrays.
