Project description:Background: Small ungulates (sheep and goat) display a seasonal breeding, characterised by successive periods of sexual activity (SA) and sexual rest (SR). In sexual activity period the ovarian cycle of females is active and ready for reproduction (oestrus) whereas in sexual rest no ovulation and reproduction are possible (deep anoestrus). Odours emitted by a sexually active male can reactivate the ovarian cycle of anoestrus females. The plasticity of the olfactory system under these hormonal changes has never been explored at the peripheral level of odours reception. As it was shown in pig that the olfactory secretome (proteins secreted in the nasal mucus) could be modified under hormonal control, we monitored its composition in females of both species along several seasons, thanks to a non-invasive sampling of olfactory mucus. Results: In both species the olfactory secretome is composed of isoforms of OBP-like proteins, generated by post-translational modifications, phosphorylation, N-glycosylation and O-GlcNAcylation. Important changes were observed in the olfactory secretome between the sexual rest and the sexual activity periods, characterised in ewe by the specific expression of SAL-like proteins and the emergence of OBPs O-GlcNAcylation. In Goat, the differences between SA and SR did not come from new proteins expression, but from different post-translational modifications, the main difference between the SA and SR secretome being the number of isoforms of each protein. Conclusion: Despite common behaviour, seasonal breeding, and genetic resources, the two species seem to adapt their sensory equipment in SA by different modalities: the variation of olfactory secretome in ewe could correspond to a specialization to detect male odours only in SA, whereas in goat the stability of the olfactory secretome could indicate a constant capacity of odours detection suggesting that the hallmark of SA in goat could be the emission of specific odours by the sexually active male.

Project description:Background The goat (Capra hircus) represents one of the most important farm animal species. It is reared in all continents with an estimated world population of about 800 million of animals. Despite its importance, studies on the goat genome are still in their infancy compared to those in other farm animal species. Comparative mapping between cattle and goat showed only a few rearrangements in agreement with the similarity of chromosome banding. We carried out a cross species cattle-goat array comparative genome hybridization (aCGH) experiment in order to identify copy number variations (CNVs) in the goat genome analysing animals of different breeds (Saanen, Camosciata delle Alpi, Girgentana, and Murciano-Granadina) using a tiling oligonucleotide array with ~385,000 probes designed on the bovine genome. Results We identified a total of 161 CNVs (an average of 17.9 CNVs per goat), with the largest number in the Saanen breed and the lowest in the Camosciata delle Alpi goat. By aggregating overlapping CNVs identified in different animals we determined CNV regions (CNVRs): on the whole, we identified 127 CNVRs covering about 11.47 Mb of the virtual goat genome referred to the bovine genome (0.435% of the latter genome). These 127 CNVRs included 86 loss and 41 gain and ranged from about 24 kb to about 1.07 Mb with a mean and median equal to 90,292 bp and 49,530 bp, respectively. To evaluate whether the identified goat CNVRs overlap with those reported in the cattle genome, we compared our results with those obtained in four independent cattle experiments. Overlapping between goat and cattle CNVRs was highly significant (P<0.0001) suggesting that several chromosome regions might contain recurrent interspecies CNVRs. Genes with environmental functions were over-represented in goat CNVRs as reported in other mammals. Conclusions We describe a first map of goat CNVRs. This provides information on a comparative basis with the cattle genome by identifying putative recurrent interspecies CNVs between these two ruminant species. Several goat CNVs affect genes with important biological functions. Further studies are needed to evaluate the functional relevance of these CNVs and their effects on behavior, production, and disease resistance traits in goats.

Project description:MicroRNAs (miRNAs) are small non-coding RNAs that regulate the post transcriptional control of several pathway intermediates, and essential for regulation in skeletal muscle of many species, such as mice, cattle, pig and so on. However, a little number of miRNAs have been reported in the muscle development of goat. In this study, the longissimus dorsi transcripts of goat at 1- and 10-month-old were analyzed for RNA-seq and miRNA-seq. The results showed that 10-month-old Longlin goat expressed 327 up- and 419 down-regulated differentially expressed genes (DEGs) compared with the 1-month-old were founded. In addition, 20 co-up-regulated and 55 co-down-regulated miRNAs involved in muscle fiber hypertrophy of goat were identified in 10-month-old Longlin and Nubian goat compared with 1-month-old. Five miRNA–mRNA pairs (chi-let-7b-3p-MIRLET7A, chi-miR193b-3p-MMP14, chi-miR-355-5p-DGAT2, novel_128-LOC102178119, novel_140-SOD3) involved in the goat skeletal muscle development were identified by miRNA–mRNA negative correlation network analysis. Our results provided an insight into the functional roles of miRNAs of goat muscle-associated miRNAs, allowing us to better understand the transformation of miRNA roles during mammalian muscle development.

Project description:Local breeds retained unique genetic variability important for adaptive potential especially in light of challenges related to climate change. Our objective was to perform, for the first time, a genome-wide diversity characterization using Illumina GoatSNP50 BeadChip of autochthonous Drežnica goat breed from Slovenia. Genetic diversity analyses revealed that the Slovenian Drežnica goat has a distinct genetic identity and is closely related to the neighboring Austrian and Italian alpine breeds. These results expand our knowledge on phylogeny of goat breeds from easternmost part of the European Alps.

Project description:Mycoplasma agalactiae (Ma) is one of the main aetiological agents of intramammary infections in small ruminants, causing contagious agalactia. To better understand the underlying disease patterns a primary goat mammary epithelial cell (pgMEC) culture was established from the mammary tissue and it was challenged with Ma. High-throughput mRNA sequencing was performed to reveal differentially expressed genes (DEG) at different time-points (3 h, 12 h, and 24 h) post infection (PI). The pathway enrichment analysis of the DEG showed that infection significantly affected pathways associated with immune response, steroid metabolism, fatty acid metabolism, apoptosis signalling, transcription regulation, and cell cycle regulation. Based on the results we suggest that mammary epithelial cells in vivo contribute to the immune system by the induced expression of cytokines and other chemotactic agents, activation of the complement system and apoptosis pathways, and expression of genes coding for antimicrobial molecules and peptides. In our study we attempted to interpret the detected transcriptomic changes in a biological context and infer mammary infection resistance candidate genes, interesting for further validation. Additionally, the results represent comprehensive goat mammary transcriptome information and demonstrate the applicability of the comparative genomics approach for annotation of goat data, using transcriptome information of a closely related species (Bos taurus) as a reference.
