Across Species Identification of Genes Bridging Neurological and Reproductive Functions in Mammals

ABSTRACT: Evolutionary success in mammals depends on coordinated neurological and reproductive functions, likely mediated by shared genes and molecular pathways between the brain and germ cells. However, direct evidence across species remains limited. Here, proteomic and transcriptomic analyses were performed experimentally in Ovis aries and Rattus norvegicus, while transcriptomic datasets from Mus musculus, Macaca mulatta, and Homo sapiens were analyzed in silico. We identified 8,464 protein-coding genes shared between the brain and sperm/testis and conserved across five species. In rats, 8,444 of these genes were also shared between the brain and the ovary. Functional annotation classified 3,890 genes as associated with both neurological and reproductive functions, and 1,752 as uncharacterized in these contexts, highlighting candidates for future studies on reproductive and neurological disorders. These findings identify a set of conserved genes shared between neurological and reproductive systems, implying a potential genetic network underlying evolutionary conservation of molecular functions across these systems.

Identification and characterization of microRNAs in the intestinal tissues of sheep (Ovis aries)

Project description:Here, we analyzed and identified the miRNA expression profile of three different intestinal tissues (i.e., duodenum, cecum, and colon) of sheep (Ovis aries) using high-throughput sequencing and bioinformatic methods. In total, 128 known miRNAs were identified, 526 novel miRNAs were predicted, and 202 differentially expressed miRNAs were found between the different tissues. Additionally, 4,422 candidate target genes were predicted, and 185 non-redundant GO annotation terms were identified using enrichment analysis. A total of 529 target genes were found to participate in 37 KEGG biological pathways, and 270 of these genes were significantly enriched in the metabolism category.

Differential proteome between ejaculate and epididymal sperm represents a key factor for sperm freezability in wild small ruminants

Project description:The proteome of two sperm sources, epididymal and ejaculated sperm, was compared and associated with sperm freezing capacity using samples collected from three wild small ruminants species. Protein identification was performed using two databases separately (Ovis aries and Capra hircus NCBI) and results were later combined.

Characterization of Sheep Milk Extracellular Vesicle-miRNA by Sequencing and Comparison with Cow milk

Project description:Milk can mediate maternal-neonatal signal transmission by the bioactive component-extracellular vesicles (EVs), which select specific types of miRNA to encapsulate. The miRNA profiling of sheep milk EVs was characterized by sequencing and compared with that of cow milk. Sheep milk EVs contained various small RNAs, including tRNA, Cis-regulatory element, rRNA, snRNA, other Rfam RNA, and miRNA, which held about 36% of all the small RNAs. Totally 84 types of miRNAs were annotated with Ovis aries by miRBase (version 22.0) in sheep milk EVs, with 75 shared types of miRNAs in all samples. Fourteen sheep milk EV-miRNAs in the top 20, occupying 98% of the total expression, were immune-related.

Differential expression analysis of miRNAs in goat (Capra hircus) mammary gland between peak and late lactation by Solexa sequencing

Project description:We report the application of Solexa high-throuthput sequencing technology for miRNA differential expression profiles. Using an optimized data analysis workflow, we mapped about 30 million sequence reads per sample to Ovis aries genome. The results were validated by qRT-PCR. Our study represents the first detailed analysis of miRNA expression profiles in goat mammary gland tissues, with biologic replicates generated by RNA-seq technology.

Aristaeus chip 1.0: an in situ synthesized oligonucleotide microarray for Ovis aries

Project description:Here we present a high-density in situ synthesized microarray for Ovis aries, named Aristaeus, designed by means of a pipeline of software instruments that, starting from non-annotated redundant EST sequences, selects oligonucleotides suitable for in situ generation on chip. The chip was tested by comparing the gene expression profiles of two sheep breeds with different phenotype, Sarda and Gentile di Puglia. We carried out microarray experiments on liver and udder tissues from lactating individuals and identified a relevant number of differentially expressed genes, all involved in metabolism pathways. The results are consistent with literature knowledge, while selected differential gene expressions have been confirmed by quantitative real-time polymerase chain reaction analyses. Tissue samples of liver were collected from 4 lactating individuals of two sheep (Ovis aries) breeds, Gentile di Puglia and Sarda. Biopsies of liver tissue were taken at second lactation stage (first record, stage 01: 6 days after lambing; second record, stage 02: 44 days after lambing) in both breeds. Tissues from liver were immersed in RNAlater (Sigma) immediately after biopsy and stored at -20°C. Samples were pooled by breed and then reverse labeled (cy5 and cy3), resulting in four raw data sets.

Project description:In this study, we applied proteomic analytical methods to modern caprine (sheep, Ovis aries and goat, Capra hircus) tooth enamel to establish a reliable method for identifying species-specific and sex-specific peptides. Utilizing single amino acid variations (SAAVs) in Enamelin (Enam) and Amelogenin (Amel) proteins, we developed a targeted parallel reaction monitoring (PRM) assay to identify molecular markers preserved in enamel of modern caprines.
