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:In animal breeding, identification of causative genetic variants is of major importance and high economical value. Usually, the number of candidate variants exceeds the number of variants that can be validated. One way of prioritizing probable candidates is by evaluating their potential to have a deleterious effect, e.g. by predicting their consequence. Due to experimental difficulties to evaluate variants that do not cause an amino-acid substitution, other prioritization methods are needed. For human genomes, the prediction of deleterious genomic variants has taken a step forward with the introduction of the combined annotation dependent depletion (CADD) method. In theory, this approach can be applied to any species. Here, we present pCADD (p for pig), a model to score single nucleotide variants (SNVs) in pig genomes. RESULTS:To evaluate whether pCADD captures sites with biological meaning, we used transcripts from miRNAs and introns, sequences from genes that are specific for a particular tissue, and the different sites of codons, to test how well pCADD scores differentiate between functional and non-functional elements. Furthermore, we conducted an assessment of examples of non-coding and coding SNVs, which are causal for changes in phenotypes. Our results show that pCADD scores discriminate between functional and non-functional sequences and prioritize functional SNVs, and that pCADD is able to score the different positions in a codon relative to their redundancy. Taken together, these results indicate that based on pCADD scores, regions with biological relevance can be identified and distinguished according to their rate of adaptation. CONCLUSIONS:We present the ability of pCADD to prioritize SNVs in the pig genome with respect to their putative deleteriousness, in accordance to the biological significance of the region in which they are located. We created scores for all possible SNVs, coding and non-coding, for all autosomes and the X chromosome of the pig reference sequence Sscrofa11.1, proposing a toolbox to prioritize variants and evaluate sequences to highlight new sites of interest to explain biological functions that are relevant to animal breeding.

Project description:Maternal exposure to estrogens can induce long-term adverse effects in the offspring. This may be mediated through alterations in the endometrium affecting embryo-maternal communication as early as the preimplantational phase. Thus, we analyzed the effects of gestational estradiol-17β (E2) exposure on the endometrium. Two distinct low doses and a high dose (0.05, 10 and 1000 µg E2/kg body weight daily, respectively) were orally applied to sows from insemination until sampling at day 10 of pregnancy and compared to carrier-treated controls. RNA-sequencing revealed a dose-dependent increase of 14, 17 and 27 differentially expressed genes (DEG), respectively. Overall, the maternal E2 treatment perturbed gene expression of the endometrium, potentially altering the uterine histotroph.

Project description:Fecal samples (N = 10) from 6- to 8-week-old wild boar piglets (Sus scrofa), collected from an animal park in Hungary in April 2011, were analyzed using viral metagenomics and complete genome sequencing. Kobuvirus (genus Kobuvirus, family Picornaviridae) was detected in all (100 %) specimens, with the closest nucleotide (89 %) and amino acid (94 %) sequence identity of the strain wild boar/WB1-HUN/2011/HUN (JX177612) to the prototype porcine kobuvirus S-1-HUN (EU787450). This study suggests that genetically highly similar (practically the same geno-/serotype) porcine kobuvirus circulate in wild boars, the wildlife counterparts of domestic pigs. Wild boars could be an important host and reservoir for kobuvirus.

Project description:Contrary to spontaneous yawning-an ancient phenomenon common to vertebrates-contagious yawning (elicited by others' yawns) has been found only in highly social species and may reflect an emotional inter-individual connection. We investigated yawn contagion in the domestic pig, Sus scrofa. Owing to the complex socio-emotional and cognitive abilities of Sus scrofa, we posited that yawn contagion could be present in this species (Prediction 1) and influenced by individual/social factors (Prediction 2). In June-November 2018, on 104 semi-free ranging adolescent/adult pigs, 224 videos were recorded for video analysis on yawning. Kinship information was refined via genetic analyses. Statistical elaboration was conducted via GLMMs and non-parametric/randomization/cross-tabulation tests. We found yawn contagion in Sus scrofa, as it was more likely that pigs yawned when perceiving rather than not perceiving (yawning/control condition) others' yawns (response peak in the first out of three minutes). Yawn contagion was more likely: (1) in response to males' yawns; (2) as the age increased; (3) within short distance (1 m); (4) between full siblings, with no significant association between kinship and distance. The influence of kinship suggests that-as also hypothesized for Homo sapiens-yawn contagion might be linked with emotional communication and possibly contagion.
