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. Two wildtype germ cell cancer (type II germ cell tumor) cell lines were analyzed.

Project description:Although piwi-interacting RNAs (piRNAs) play pivotal roles in spermatogenesis, little is known about piRNAs in the seminal plasma of infertile males. In this study, we systematically investigated the profiles of seminal plasma piRNAs in infertile males to identify piRNAs that are altered during infertility and evaluate their diagnostic value. Seminal plasma samples were obtained from 211 infertile patients (asthenozoospermia and azoospermia) and 91 fertile controls. High-throughput sequencing technology was employed to screen piRNA profiles in seminal plasma samples pooled from healthy controls and infertile patients. The results identified 61 markedly altered piRNAs in the infertile patient groups compared with the control group. Next, a quantitative RT-PCR assay was conducted in the training and validation sets to measure and confirm the concentrations of altered piRNAs. The results identified a panel of 5 piRNAs that were significantly decreased in the seminal plasma of infertile patients compared with healthy controls. The areas under the ROC curves for these piRNAs ranged from 0.796 to 0.996, suggesting that the diagnostic potential of these 5 piRNAs to distinguish asthenozoospermic and azoospermic individuals from healthy controls was high. In summary, this study identifies a panel of piRNAs that can accurately distinguish fertile from infertile males. This finding may provide pathophysiological clues that are involved in the development of infertility. Fresh samples were collected and stored at -80â??.Total RNA of seminal plasma were extracted and solexa sequencing was performed.

Project description:Heterogeneity within murine prospermatogonia manifests as certain populations either die or survive during a developmentally scheduled apoptotic event at E13.5. We have identified that this apoptosis is clonal, suggesting that apoptotic fate is heritably enforced among populations of germ cells. To determine how subpopulations of germ cells differ, we used single-cell RNA sequencing to identify two diametric states: an apoptotic (AP) versus a male-differentiated (MD) subpopulation that differ primarily by the expression of critical male-differentiation genes known to be epigenetically regulated. We isolated AP and MD germ cells from E13.5 male embryos for whole genome bisulfite sequencing to compare how methylation differs between these populations. We find that AP germ cells are relatively hypermethylated at a whole-genome level and, importantly, are significantly hypermethylated at specific genome-reprogramming responsive (GRR) loci. Because these GRR genes facilitate male differentiation, we conclude that inappropriate demethylation as germ cells epigentically reprogram in the period preceding apoptosis produces an aberrantly male-differentiated clone that is fated for elimination. This quality-control paradigm therefore links fidelitous epigenetic reprogramming to germ cell selection.
