Project description:We employed whole genome gene expression analysis to characterize the intestinal exposure to 5 closely related food contaminants belonging to the type B trichocene mycotoxins groups The few data available on fusarenon-X (FX) do no support derivation of health-based guidance values for this mycotoxin, although preliminary results suggest higher toxicity compared to other regulated trichothecenes. Using histo-morphological analysis and whole-transcriptome profiling, the present study was designed to get a global view of intestinal alterations induced by FX. The well-described trichothecene deoxynivalenol (DON) served as a benchmark. FX exposure induced more severe intestinal histological alterations compared to DON. Intestinal inflammation was the hallmark of the molecular toxicity of DON, but also of FX. The dose-response analysis for FX revealed that benchmark doses for up-regulation of key-inflammatory genes expression were 4 to 45-fold higher than the previously reported ones for DON. Transcriptome analysis revealed that both mycotoxins down-regulated PPAR and LXR-RXR signaling pathways controlling lipid metabolism. Interestingly, several pathways including VDR/RXR activation, ephrin receptor signaling, and GNRH signaling were specific to FX and thus, discriminate the intestinal transcriptomic fingerprint of the two mycotoxins. Altogether, these results demonstrate that FX induces a more potent intestinal inflammation than DON. This study also reveals specific FX-targeted pathways, indicating that the toxicity of DON cannot serve as a benchmark for FX, and that toxicity evaluation of each trichothecene should be conducted separately.

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: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

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.
