Project description:Type II testicular germ cell cancers (GCC) are the most frequently diagnosed tumors in young men (20 - 40 years) and are classified as seminoma or non-seminoma. GCCs are commonly treated by orchiectomy and chemo- or radiotherapy. However, a subset of metastatic non-seminomas display only incomplete remission or relapse and require novel treatment options. Recent studies have shown effective application of the small-molecule inhibitor JQ1 in tumor therapy, which interferes with the function of bromodomain and extra-terminal (BET)-proteins. Here, we demonstrate that upon JQ1 doses ≥ 250 nM GCC cell lines and Sertoli cells display compromised survival and induction of cell cycle arrest. JQ1 treated GCC cell lines display upregulation of genes indicative for DNA damage and a cellular stress response. Additionally, downregulation of pluripotency factors and induction of mesodermal differentiation was detected. GCCs xenografted in vivo showed a reduction in tumor size, proliferation and angiogenesis when subjected to JQ1 treatment. The combination of JQ1 and the histone deacetylase inhibitor romidepsin further enhanced the apoptotic effect in vitro and in vivo. Thus, we propose that JQ1 alone, or in combination with romidepsin may serve as a novel therapeutic option for GCCs.

Project description:To identifiy stage-dependent genes in Sertoli cells, we performed expression microarray analysis of the adult whole testes, cultured primary Sertoli cells, Sertoli cells directly isolated from wild-type and Nanos3 (germ-less) testes,seminiferous tubules at stages I-III, IV-VI, VII-VIII and IX-XII. Next to examine the relationship between stage-dependent gene expression change and retinoic acid signaling, we performed expression microarray analysis of the cultured primary Sertoli cells treated with retinoic acid and stage-specific seminiferous tubules injected with lentivirus containing Venus or dominat negative form of RARa, a dominant receptor for retinoic acid in Sertoli cells.

Project description:Background: Germ Cell Cancers (GCC), originating from Primordial Germ Cells /gonocytes, are the most common cancer in young men, subdivided in seminoma (SE) and non-seminoma (NS, stem cell component: embryonal carcinoma (EC)). Somatic mutations are rarely found in GCC. It has been proposed that disruption of the epigenetic constitution, either primarily or secondary (e.g. environmental influences), is involved in cancer, and specifically in GCC. Results: This study aims at identifying epigenetic footprints of SE and EC cell lines in genome-wide profiles by studying the interaction between gene expression, DNA CpG methylation and histone modifications, and their function in GCC and related disruption of germ cell maturation. Two well characterized GCC-derived cell lines were compared, one representative for SE (TCam-2) and the other for EC (NCCIT). Data was acquired using the Illumina HumanHT-12-v4 (gene expression) and HumanMethylation450 BeadChip (methylation) microarrays as well as ChIP sequencing (activating histone modifications (H3K4me3, H3K27ac)). The data show that known germ cell markers are not only present and differentiating between SE and NS at the expression level, but also in the epigenetic landscape. Conclusion: The overall similarity between TCam-2 / NCCIT supports an erased embryonic gem cell arrested in early gonadal development as common origin. Subtle difference in the (integrated) epigenetic and expression profiles indicated TCam-2 to exhibit a more germ cell like profile (enrichment Androgen regulation) while NCCIT proved more pluripotent. The results provide insight into an integrated analysis of the functional genome in GCC cell lines.

Project description:We performed global scale microarray analysis to identify detailed mechanisms by which bisphenol A (BPA) induce cell death by using an Affymetrix GeneChip system. Testicular Sertoli TTE3 cells used in the present study were derived from transgenic mice harboring a temperature-sensitive simian virus 40 large T-antigen. Cell death accompanying endoplasmic reticulum stress was observed in the cells treated with 0.2 mM BPA. Of the 22,690 probe sets analyzed, approximately 1,300 genes were down- and up-regulated by a factor of 2.0 or greater in the cells treated with BPA. Keywords: bisphenol A, gene expression, testicular Sertoli cell
