Project description:Minipigs have favorable biological characteristics for juvenile toxicity studies to assess efficacy and safety of pediatric drug products. To evaluate at the molecular level the expression of drug targets, drug metabolism pathways or general maturation of organ transcriptomes in minipigs, we used Customized Agilent Micoarrays (Design-ID 050244) for genome-wide gene expression profiling on 9 different tissues from male and female juvenile Göttingen minipigs aged 1 week to 24 months. The gene expression results analyzed in this study are further described in Heckel T. et al. (2015) Functional analysis and transcriptional output of the Göttingen minipig genome. under submission
Project description:Minipigs resemble many features of human anatomy, physiology, and biochemistry and represent an animal model for drug efficacy and safety testing. To evaluate at the molecular level the expression of drug targets, drug metabolism pathways or general features of organ transcriptomes in minipigs, we used Customized NimbleGen Microarrays (Design-ID: 120229_MiniPig_TH_expr_HX12) for genome-wide gene expression profiling on 18 different tissues from 6 male and 6 female Göttingen minipigs. The gene expression results analyzed in this study are further described in Heckel T. et al. (2015) Functional analysis and transcriptional output of the Göttingen minipig genome. under submission

(2015) Functional analysis and transcriptional output of the Göttingen minipig genome. under submission Data of 72 different tissue samples from 9 tissues (cerebral cortex, hypothalamus, cerebellum, liver, kidney, spleen, bone marrow, testis, ovary) and 4 age groups in female (1 week, 4 weeks, 2 months, 4 months) and 5 age groups in male (1 week, 4 weeks, 2 months, 4 months, 2 years) Goettingen minipigs (Ellegaard) were measured. One tissue was measured in 8 technical replicates. The combination of data of female and male pigs could be seen as a kind of biological replicate for most genes.
Project description:Minipigs are animal models widely used in biomedical studies due to their physiological and anatomical similarities to humans. However, a comprehensive resource for the Korean minipig (Sus scrofa) transcriptome remains unavailable. In this study, we constructed a de novo transcriptome of the Korean minipig using RNA-seq data obtained from ten tissues across ten samples. The final assembly comprised 57,085 coding transcripts with an average length of 3,075 nucleotides and an N50 of 4,258 nucleotides. In total, 65.4% of the transcripts were annotated, and biological functions were assigned. Transcript expression profiling and principal component analysis showed that samples clustered by tissue type, reflecting transcriptomic features shared across tissues. Comparative analysis demonstrated that the novel transcriptome assembly had contiguity and completeness comparable to those available for pig and minipig breeds. Overall, this study provides a comprehensive transcriptomic resource for the Korean minipig, facilitating further functional analyses.

Project description:Male Göttingen Minipigs were divided into 4 groups: SD (standard diet, n=8), FFC (FFC diet, n=16), FFC-DIA (FFC diet + diabetes, n=14), FFC-DIA+S (FFC diet with extra salt + diabetes, n=14). Blood and urine biomarkers, glomerular filtration rate (GFR), blood pressure and resistive index (RI) were evaluated after 6-7 months (T1) and 12-13 months (T2). Histology, electron microscopy and gene expression (excluding FFC-DIA+S) were evaluated at T2. Göttingen Minipigs fed FFC diet displayed some of the characteristic features of human ORG. Presence of diabetes on top of FFC diet, lead to changes resembling the early phases of human DN.
Project description:Gene expression of characteristic chondrogenic markers and miRNA expression were analyzed in cells cultured in differentiation medium and significant differences were found between gelation/PRP microgels and those containing only pure gelatin. We used microarrays to detail the miRNA expression in studied cell cultures for identification the expression of miRNA and study the up- and down-regulated miRNA associated.
Project description:Obesity is a well-recognized risk factor for increased severity following influenza A virus (IAV) infection, likely by promoting meta-inflammation and immune dysregulation, but its effects on antiviral and inflammatory responses remain poorly understood. Using a Göttingen minipig model of diet-induced obesity, we compared antiviral and inflammatory responses before and after IAV infection. Respiratory tract transcriptomics and histopathology revealed no clear obesity-associated immune or inflammatory changes in uninfected minipigs. In contrast, obese pigs showed reduced viral clearance in nasal mucosal tissue accompanied by altered antiviral gene expression pattern four days post infection. Furthermore, cellular infiltration of the respiratory tract was observed in obese pigs after infection. Finally, C-reactive protein concentrations increased significantly in obese pigs, indicating enhanced systemic inflammation in response to respiratory infection. These findings demonstrate that diet-induced obesity in Göttingen minipigs is associated with altered antiviral and inflammatory responses following IAV infection and support the translational value the obese minipig model.
