Project description:Nine groups of rat tongue tissue RNA samples, including three from normal control, three from 4NQO induced tongue tissue, and three from 4NQO induced and IL-1Ra interference tongue tissue (3 rats per group) were collected for gene microarray hybridization.
Project description:Male Sprague-Dawley rats were used to establish exhausted-exercise model by motorized rodent treadmill. Yu-Ping-Feng-San at doses of 2.18 g/kg was administrated by gavage before exercise training for 10 consecutive days. Quantitative proteomics was performed for assessing the related mechanism of Yu-Ping-Feng-San.
Project description:Determine whether 4NQO treatment may modulate gene expression in mouse tongue. C57BL/6J mice were given 4NQO (100ug/ml in drink) for 8 weeks; Non-treated control samples were used for comparison.

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:Through gene expression profiling in cultured lymphocytes and PBMCs from a large set of T1D patients and controls, we demonstrate that IL-1ra may protect against the development of islet autoimmunity and T1D through down-regulating a large number of inflammatory genes and pathways. Keywords: autoimmunity; IL-1Ra;Type 1 diabetes (T1D) To elucidate the molecular mechanism underlying the action of IL-1ra, we profiled gene expression in peripheral blood mononuclear cells (PBMC) cultured with sera from low or high IL-1ra subjects. To avoid potential heterogeneity in responder cells from different subjects, PBMCs from one healthy donor were cultured for six hours with 20% of sera from six subjects with low IL-1ra and six subjects with high IL-1ra. Gene expression in the cultured cells was analyzed with the Illumina HumanRef-8 v3.0 beadchips
Project description:The effect of gain of function mutations in p53, pik3ca, and both genes in mouse tongue subject to 4NQO treatment on gene expression is characterized by RNASeq.
