Project description:Here we asked whether infiltration of leukemic blasts initiated a response that could be detected in the interstitial fluid phase of the spleen in a rat model known to mimic human acute myeloid leukemia (AML). By cannulating efferent lymphatic vessels, we were able to monitor the response of the spleen microenvironment during leukemia development. Flow cytometric analysis of lymphocytes isolated from spleen lymph showed increased STAT3 and CREB signaling, and proteins related to these pathways were identified with a different profile in leukemic when compared with control spleen lymph. Additionally, SPARC-like 1 protein, recently identified as a promoter of AML cell growth and a biomarker of patient outcome, was locally produced in the spleen and upregulated in the leukemic setting. Thus, interstitial fluid, and its surrogate efferent lymph, can be used to provide unique information about spleen responses and substances released to the general circulation during leukemia development.

Project description:Heathly naked mole-rats kept under normal housing conditions harbor either a small or enlarged spleen. The aim of the study is to compare RNAseq of naked mole-rat (NM-R) small and enlarged spleens between them and to compare them with RNAseq of mouse spleen.

Project description:The rat has been used extensively as a model for evaluating chemical toxicities and for understanding drug mechanisms. However, its transcriptome across multiple organs, or developmental stages, has not yet been reported. Here we show, as part of the SEQC consortium efforts, a comprehensive rat transcriptomic BodyMap created by performing RNASeq on 320 samples from 11 organs of both sexes of juvenile, adolescent, adult and aged Fischer 344 rats. We catalogue the expression profiles of 40,064 genes, 65,167 transcripts, 31,909 alternatively spliced transcript variants and 2,367 non-coding genes/non-coding RNAs (ncRNAs) annotated in AceView. We find that organ-enriched, differentially expressed genes reflect the known organ-specific biological activities. A large number of transcripts show organ-specific, age-dependent or sex-specific differential expression patterns. We create a web-based, open-access rat BodyMap database of expression profiles with crosslinks to other widely used databases, anticipating that it will serve as a primary resource for biomedical research using the rat model. We constructed a comprehensive RNA-Seq data set for studying the dynamics of the rat transcriptome using 320 RNA samples isolated from 11 organs (adrenal gland, brain, heart, kidney, liver, lung, muscle, spleen, thymus, and testes or uterus) from both sexes of Fischer 344 rats across four developmental stages (2-, 6-, 21-, and 104-weeks-old). Four biological replicates were used for each of the 80 sample groups.

Project description:We demonstrate a different strategy that successfully transformed an existing, functionally dispensable organ to regenerate another, functionally vital one in the body. Specifically, we injected STH into the mouse spleen to remodel its tissue structure, and implanted in there human or rat liver cell lines. The remodeled spleen developed an immunosuppressive, yet highly vascularized microenvironment, in which the trans-species cells proliferated fast and developed the functions of the human liver through 8 weeks, without exerting adverse responses.

Project description:In this study, the spleen deficiency syndrome rat model was built with reserpine injection method. At first, the intervention effect of SJZD on spleen deficiency syndrome was preliminary evaluation through pharmacodynamics study. By comparing the differences proteins of liver tissues by label-free proteomics techniques, the differentially expressed proteins of spleen deficiency syndrome and SJZD intervention spleen deficiency syndrome were screened. At last, differentially expressed proteins were analyzed with bioinformatics analysis method, the potential target proteins of spleen deficiency syndrome and SJZD intervention spleen deficiency syndrome were excavated. At the same time, the corresponding metabolic pathways and biological molecular interaction network was established. We hope to probe the mechanisms of SJZD intervention spleen deficiency syndrome from the aspect of proteomic to provide a scientific basis for the clinical diagnosis and treatment of spleen deficiency syndrome.

Project description:Hexachlorobenzene (HCB) [CAS:118-74-1; CHEBI:5692] is a persistent environmental pollutant with toxic effects in man and rat. Reported adverse effects are hepatic porphyria, neurotoxicity, and adverse effects on the reproductive and immune system. To obtain more insight into HCB-induced mechanisms of toxicity, we studied gene expression levels using DNA microarrays. For 4 weeks, Brown Norway rats were fed a diet supplemented with 0, 150, or 450 mg HCB/kg. Spleen, mesenteric lymph nodes (MLN), thymus, blood, liver, and kidney were collected and analyzed using the Affymetrix rat RGU-34A GeneChip microarray. Most significant (p < 0.001) changes, compared to the control group, occurred in spleen, followed by liver, kidney, blood, and MLN, but only a few genes were affected in thymus. This was to be expected, as the thymus is not a target organ of HCB. Transcriptome profiles confirmed known effects of HCB such as stimulatory effects on the immune system and induction of enzymes involved in drug metabolism, porphyria, and the reproductive system. In line with previous histopathological findings were increased transcript levels of markers for granulocytes and macrophages. New findings include the upregulation of genes encoding proinflammatory cytokines, antioxidants, acute phase proteins, mast cell markers, complements, chemokines, and cell adhesion molecules. Generally, gene expression data provide evidence that HCB induces a systemic inflammatory response, accompanied by oxidative stress and an acute phase response. In conclusion, this study confirms previously observed (immuno)toxicological effects of HCB but also reveals several new and mechanistically relevant gene products. Thus, transcriptome profiles can be used as markers for several of the processes that occur after HCB exposure.
