Genome-wide analysis of gene expression in TM4 Sertoli cells following siRNA-mediated Gata4 inhibition

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 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.

Vitamin C modulates function and gene expression of mouse testis TM4 Sertoli cells

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.

Genome-wide analysis of gene expression in TM4 Sertoli cells following siRNA-mediated Gata4 inhibition

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)

RNA-seq of C18-4 and TM4 cells samples from different M5 receptor modification groups

Project description:The goat of this project is to explore M5 receptor regulation spermatogenesis. We tried to search the mechanism of M5 receptor regulation spermatogenesis. RNA-seq of C18-4 and TM4 cells samples from different groups: C3NC, M5 knockdown in C18-4, TM3NC, M5 knockdown in TM4 cells. The cell were transfected with virus with inhibition of M5 expression ( M5 gene knockdown).

Transgenerational transcriptomic and DNA methylome profiling of mouse fetal testicular germline and somatic cells after exposure of pregnant mothers to tributyltin, a potent obesogen

Project description:Obesogens such as tributyltin (TBT) are xenobiotic compounds that promote obesity, in part by distorting the normal balance of lipid metabolism. The obesogenic effects of TBT can be observed in directly exposed (F1 and F2 generations) and also subsequent generations (F3 and beyond) that were never exposed. To address the effects of TBT exposure on germ cells, we exposed pregnant transgenic OG2 mouse dams (F0), which specifically express EGFP in germline cells, to an environmentally relevant dose of TBT throughout gestation through drinking water. When fed with a high fat diet (HFD), F3 male offspring of TBT-exposed F0 dams (TBT-F3) accumulated much more body fat than did Control-F3 males. TBT-F3 males also lost more body fluid and lean compositions than did Control-F3 males. Expression of genes involved in transcriptional regulation or mesenchymal differ-entiation was upregulated in somatic cells of TBT-F1 (but not TBT-F3) E18.5 fetal testes, and promoter-associated CpG islands were hyper-methylated in TBT-F1 somatic cells. Global mRNA expression of protein-coding genes in F1 or F3 fetal testicular cells was unaffected by F0 exposure to TBT; however, expression of a subset of endogenous retroviruses was significantly affected in F1 and F3. We infer that TBT may directly target testicular somatic cells in F1 testes to irreversibly affect epigenetic suppression of endogenous retroviruses in both germline and somatic cells.
