Project description:To understand the mechanisms of sexual behaviour in rams, transcriptomic sequencing technology was used to identify differentially expressed genes in peripheral blood We then performed gene expression profiling analysis using data obtained from blood in rams with different sexual behaviours, intending to identify in vivo sexual behaviour biomarkers

Project description:To understand the mechanisms of sexual behaviour in rams, transcriptomic sequencing technology was used to identify differentially expressed genes in key brain tissues We then performed gene expression profiling analysis using data obtained from RNA-seq of hypothalamus (HT), pars tuberalis (PT) and pineal gland (PG) in rams with different sexual behaviours

Project description:Infection of sheep with Brucella ovis results in ovine brucellosis, a disease characterized by infertility in rams, abortion in ewes and increased perinatal mortality in lambs. During the course of the infection both the ovine immune response and host cell gene expression are modified. The objective of this research was to conduct a preliminary characterization of differential gene expression in rams experimentally infected with B. ovis by microarray hybridization and real-time RT-PCR.

Project description:Background Urothelial carcinoma of the bladder (UC) is a common malignancy. Although extensive transcriptome analysis has provided insights into the gene expression patterns of this tumor type, the mechanistic underpinnings of differential methylation remain poorly understood. Multi-level genomic data may be used to profile the regulatory potential and landscape of differential methylation in cancer and gain understanding of the processes underlying epigenetic and phenotypic characteristics of tumors. Methods We perform genome-wide DNA methylation profiling of 98 gene-expression subtyped tumors to identify between-tumor differentially methylated regions (DMRs). We integrate multi-level publically available genomic data generated by the ENCODE consortium to characterize the regulatory potential of UC DMRs. Results We identify 5,453 between-tumor DMRs and derive four DNA methylation subgroups of UC with distinct associations to clinicopathological features and gene expression subtypes. We characterize three distinct patterns of differential methylation and use ENCODE data to show that tumor subgroup-defining DMRs display differential chromatin state, and regulatory factor binding preferences. Finally, we characterize an epigenetic switch involving the HOXA-genes with associations to tumor differentiation states and patient prognosis. Conclusions Genome-wide DMR methylation patterns are reflected in the gene expression subtypes of UC. UC DMRs display three distinct methylation patterns, each associated with intrinsic features of the genome and differential regulatory factor binding preferences. Epigenetic inactivation of HOX-genes correlates with tumor differentiation states and may present an actionable epigenetic alteration in UC.

Project description:This study investigates the feasibility and efficacy of an Internet-delivered intervention for the sexual and intimate re-adjustment of couples in which one partner is living with a temporary or permanent ostomy (e.g., colostomy, ileostomy, urostomy) following treatment for colorectal and/or bladder cancer. The two session intervention will be delivered via online videoconferencing and will focus on facilitating couples’ communication around their sexual and intimate relationship. Exercises from sex therapy will be used to scaffold conversations about motivations for having sex, intimacy and sensual pleasure, and relational strengths for coping. The intervention aims to enhance couples’ ability to cope with the changes in their sexual and intimate relationship. A group of couples receiving written educational material only will be used as a comparison group to measure change in sexual and intimate adjustment over time.

Project description:We report a distinctive gene-targeted RNA-directed DNA methylation (RdDM) activity in the Arabidopsis thaliana male sexual lineage that regulates gene expression in meiocytes. Loss of sexual-lineage-specific RdDM causes mis-splicing of the MPS1 gene (also known as PRD2), thereby disrupting meiosis. Our results establish a regulatory paradigm in which de novo methylation creates a cell-lineage-specific epigenetic signature that controls gene expression and contributes to cellular function in flowering plants.

Project description:In this study we screened for changes of DNA methylation in response to X-irradiation in the lymphoblastoid cell line GM12878 and the primary lung fibroblast cell line IMR90. We employed methylated DNA-Immunoprecipitation in combination with genome wide and region specific DNA microarrays to identify preferences of radiation induced changes of methylation with respect to genomic and epigenomic characteristics.
