Project description:Effects of oil pollution and persistent organic pollutants (POPs) on the glycerophospholipids in the liver of male Atlantic cod (Gadus morhua)
Project description:Accumulating evidence suggests that poly- and perfluoroalkyl substances (PFAS), a class of persistent organic pollutants, cause changes in hepatic lipid, amino acid, and glucose metabolism. Our study explores the molecular mechanisms whereby PFHxS, PFOA, PFOS, and PFNA disrupt liver metabolism.

Our study explores the molecular mechanisms whereby PFHpA disrupts liver metabolism and facilitate NAFLD development.
Project description:Transcriptional Regulation in Testis Associated with Developmental and Reproductive Effects in Male Zebrafish Exposed to Natural Mixtures of Persistent Organic Pollutants from Mjosa Lake
Project description:Transcriptional Regulation in liver and ovary associated with developmental and reproductive effects in female Zebrafish exposed to natural mixtures of persistent organic pollutants from Lake Mjosa or Lake Losna
Project description:Exposure to Persistant Organic Pollutants (POPs) is known to cause serious health effects in human but the gene expression profiles leading to development of differnet diseases and disorders are not fully understood. The knowledge of global gene expression will help us to devlop early disease or disorder biomarkers for POP induced health effects. We used microarrays to detail the global gene expression profile underlying the effects of high POP exposure to Slovak 45 month children leading to identification of distinct classes of up-regulated and down-regulated genes and cellular processes.
Project description:The Norway rat has important impacts on our life. They are amongst the most used research subjects, resulting in ground-breaking advances. At the same time, wild rats live in close association with us, leading to various adverse interactions. In face of this relevance, it is surprising how little is known about their natural behaviour. While recent laboratory studies revealed their complex social skills, little is known about their social behaviour in the wild. An integration of these different scientific approaches is crucial to understand their social life, which will enable us to design more valid research paradigms, develop more effective management strategies, and to provide better welfare standards. Hence, I first summarise the literature on their natural social behaviour. Second, I provide an overview of recent developments concerning their social cognition. Third, I illustrate why an integration of these areas would be beneficial to optimise our interactions with them.
Project description:BackgroundMurine kobuviruses (MuKV) are newly recognized picornaviruses first detected in murine rodents in the USA in 2011. Little information on MuKV epidemiology in murine rodents is available. Therefore, we conducted a survey of the prevalence and genomic characteristics of rat kobuvirus in Guangdong, China.ResultsFecal samples from 223 rats (Rattus norvegicus) were collected from Guangdong and kobuviruses were detected in 12.6% (28) of samples. Phylogenetic analysis based on partial 3D and complete VP1 sequence regions showed that rat kobuvirus obtained in this study were genetically closely related to those of rat/mouse kobuvirus reported in other geographical areas. Two near full-length rat kobuvirus genomes (MM33, GZ85) were acquired and phylogenetic analysis of these revealed that they shared very high nucleotide/amino acids identity with one another (95.4%/99.4%) and a sewage-derived sequence (86.9%/93.5% and 87.5%/93.7%, respectively). Comparison with original Aichivirus A strains, such human kobuvirus, revealed amino acid identity values of approximately 80%.ConclusionOur findings indicate that rat kobuvirus have distinctive genetic characteristics from other Aichivirus A viruses. Additionally, rat kobuvirus may spread via sewage.
Project description:Inflammation is a key component of pathological angiogenesis. Here we induce cornea neovascularisation using sutures placed into the cornea, and sutures are removed to induce a regression phase. We used whole transcriptome microarray to monitor gene expression profies of several genes
