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: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.

Each microarray measures the expression level of 24,499 probe sets covering 17,261 genes with five 60-mer probes (PM) per probe set. The number of replicates is 1 - i.e., only one set of probes on the array. The design includes 16,642 random GC probes for the estimation of the signal threshold and 1536 ERCC control probes.
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:To optimize the genome annotation, nine tissue and one pool RNA libraries (i.e. heart, liver, spleen, lung, kidney, muscle, fat, ovary, pool.) were constructed using the Illumina mRNA-spleeneq Prep Kit
Project description:Regulatory Mechanisms of Atrial Remodeling of Mitral Regurgitation Pigs This study enrolled 6 pigs (age: 18 months) and divided into three groups: mitral regurgitation pigs (MR) (n = 2; 2 males sacrificed 12 months after surgery), MR pigs treated with valsartan (MRV) (n = 2; 2 males age-matched to MR sacrificed 12 months after surgery), and normal control pigs (NC) (n = 2; 2 males age-matched to MR pigs). Valsartan (3.43 mg/kg/day), a type I angiotensin II receptor blocker, was administered from one week before surgery and then daily after surgery in the MRV group. We sought to systemically elucidate critical differences in the alteration of RNA expression pattern between the atrial myocardium of pigs with and without MR, and between the atrial myocardium of MR pigs with and without valsartan using high-density oligonucleotide microarrays and functional network enrichment analysis.
Project description:Large White and Meishan pigs were either non-treated or injected with mammalian 1-24 ACTH (Immediate Synachten, Novartis France) at the dose of 250 µg per animal. Pigs were sacrificed either immediately after capture from their home cage (non-treated animals) or 1 hour following ACTH injection. Adrenal glands were immediately collected from pigs and frozen on dry ice and then stored at -80°C until RNA isolation. Keywords: stress response, adrenal, gene expression, pig
