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:Purpose: This study conducted RNA-Seq analysis on Dingyuan pig individuals with different intramuscular fat content and backfat thickness, in order to find genes that specifically regulate subcutaneous fat and intramuscular fat deposition in pigs

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:Background: Marketing products with added-value characteristics is a current trend in livestock production systems. Regarding meat, selection for intramuscular fat and muscular fatty acid composition is a way to improve the palatability and juiciness of meat while assuring a healthy fat content. This represents selecting animal with a different muscular metabolic profile with respect to the extended selection of lean animals. Results: The present study has analysed the muscular gene expression profiles of 68 commercial Duroc pigs belonging to two groups with extreme phenotypes for traits strongly related with lipid deposition and composition. This has allowed us to compare the physiological and metabolic implications of selecting for each of these extreme groups. Rather than upregulation of a single pathway, the main differences lied on the transcriptional levels of genes related with lipogenesis and lipolysis, revealing the existence of a cycle where triacylglycerols are continuously synthesized and degraded. Most strikingly, several genes which enhanced fatty acid β-oxidation and favoured insulin signalling and glucose uptake were upregulated in the fattest animals, indicating that the events leading to peripheral insulin resistance in humans with increased levels of intramuscular fat and obesity do not take place in these pigs. Moreover, neither was detected the well-characterised low-grade inflammatory state observed in overweighed humans. Conclusion: As a whole, our data suggest that selection for increasing intramuscular fat content in pigs would lead to a shift but not a disruption of the metabolic homeostasis of muscle cells. Future studies on the post-translational changes affecting protein activity or expression as well as information about protein location within the cell would be needed to fully understand how lipid deposition affects muscle physiology in pigs. 68 gluteus medius samples form 68 animals belonging to two groups of 34 animals each: HIGH group had higher carcass, plasma and muscle fat content; LOW group had lower carcass, plasma and muscle fat content

Project description:Gene expression profiling in a Duroc/Landrace pig population differing in intramuscular fat content

Project description:The content of intramuscular fat (IMF) is closely related to meat quality traits. In this study, in order to explore the candidate genes related to IMF content, the longissimus dorsi muscle of Guangling donkey was measured for intramuscular fat content. According to its intramuscular fat content, it was divided into two groups, the low fat group (L , N=3) and high-fat group (H, n=3), using RNA-seq to identify differentially expressed genes (DGEs) on the longissimus dorsi muscle tissue of Guangling donkey with high and low intramuscular fat content to reveal the possibility Gene network and metabolic pathways that help increase intramuscular fat content. A total of 167 DEGs (|log2Fold Change|>=1 and FDR<0.05) were detected in the high (H) and low (L) groups of Guangling donkeys, of which 64 were up-regulated genes and 103 were down-regulated genes. The GO enrichment and KEGG pathway analysis showed that these differential genes were enriched in several biological processes and pathways related to adipocyte differentiation, lipid biosynthesis, and neutral lipid metabolism. These results will help to further explore the molecular mechanism of IMF deposition in donkeys and provide a theoretical basis for the molecular breeding of Guangling donkeys.

Project description:Intramuscular (i.m.) fat content influencing consumer’s acceptability of pork is considered as a limiting factor for meat quality. To gain insight into the biological basis of individual variability in i.m. fat content, both gene expression profiling and proteomic investigation were associated in pig longissimus muscle (LM).
