Project description:Exome sequencing of goats reveals adaptation to high altitude
| PRJNA281774 | ENA
Project description:High-altitude adaptation is a representative example of vertebrates getting adapted to harsh and extreme environments. To investigate the miRNA expression alterations of goats that were induced by high altitude stress, we performed comparative miRNA transcriptome analysis on six hypoxia-sensitive tissues (heart, kidney, liver, lung, skeletal muscle and spleen) in two indigenous goat populations from distinct altitudes (600 m and 3000 m). We obtained the expression of 1391 mature miRNAs and identified 138 differentially expressed miRNAs between altitudes. Combined with tissue specificity analysis, we illustrated alterations of expression levels between altitudes and among tissues, which suggested the coexisting tissue-specific and tissue-conserved mechanism for hypoxia adaptation. Notably, the interplay between DE miRNA and DE target genes strongly indicated post-transcriptional regulation in HIF-1 signaling pathway, insulin signaling pathway and p53 signaling pathway, which might play a significant role in high altitude adaptation in domestic goats. These results provide insights into the complicated miRNA expression pattern and regulatory mechanism of high altitude adaptation in domestic goats.

Project description:The domestic goat, Capra hircus (2n=60), is one of the most important domestic livestock species in the world. Here we report its high quality reference genome generated by combining Illumina short reads sequencing and a new automated and high throughput whole genome mapping system based on the optical mapping technology which was used to generate extremely long super-scaffolds. The N50 size of contigs, scaffolds, and super-scaffolds for the sequence assembly reported herein are 18.7 kb, 3.06 Mb, and 18.2 Mb, respectively. Almost 95% of the supper-scaffolds are anchored on chromosomes based on conserved syntenic information with cattle. The assembly is strongly supported by the RH map of goat chromosome 1. We annotated 22,175 protein-coding genes, most of which are recovered by RNA-seq data of ten tissues. Rapidly evolving genes and gene families are enriched in metabolism and immune systems, consistent with the fact that the goat is one of the most adaptable and geographically widespread livestock species. Comparative transcriptomic analysis of the primary and secondary follicles of a cashmere goat revealed 51 genes that were significantly differentially expressed between the two types of hair follicles. This study not only provides a high quality reference genome for an important livestock species, but also shows that the new automated optical mapping technology can be used in a de novo assembly of large genomes. Corresponding whole genome sequencing is available in NCBI BioProject PRJNA158393. We have sequenced a 3-year-old female Yunnan black goat and constructed a reference sequence for this breed. In order to improve quality of gene models, RNA samples of ten tissues (Bladder, Brain, Heart, Kidney, Liver, Lung, Lymph, Muscle, Ovarian, Spleen) were extracted from the same goat which was sequenced. To investigate the genic basis underlying the development of cashmere fibers using the goat reference genome assembly and annotated genes, we extracted RNA samples of primary hair follicle and secondary hair follicle from three Inner Mongolia cashmere goats and conducted transcriptome sequencing and DGE analysis. This submission represents RNA-Seq component of study.

Project description:Purpose: Domestic goats distributed in a wide range of habitats and have evolved genetic adaptations to their local environmental conditions. The goal of this study s to investigate the dramatic gene expression changes of goats that are shaped by high altitude adaptation. Methods: We performed RNA-seq on 27 samples from the three hypoxia-sensitive tissues (heart, lung and skeletal muscle) in three indigenous populations residing in distinct altitudes (600 m, 2,000 m and 3,000 m). Results: We identified numerous differentially expressed genes which exhibited distinct expression patterns, and nonsynonymous SNVs-containing genes which highly differentiated between the high- and low-altitude populations. Conclusions: These identified genes have known or potential roles in hypoxia response, and enriched in functional gene categories potentially responsible for high altitude adaptation, are appealing candidates for further investigation of the adaptive evolution in harsh high-altitude environment.

Project description:Molecular mechanisms of follicular atresia and prolificacy of mammal remain unclear. We surveyed the single-cell transcriptomic landscape of ovaries from single and prolificacy goat and identified seven ovarian cell types with distinct gene-expression, transcriptional factor networks and reciprocal interactions signatures. In-depth dissection of gene-expression dynamics of granulosa cells (GCs) that displayed development stage-specific expression patterns and specific gene signatures were identified that may reflect developmental competency and ovarian reserve. what’s more, we revealed the origin of theca cells. Further analysis of cell-type-specific prolificacy-associated transcriptional changes uncovered apoptosis, anabolism and response to hormone stimulation as are crucial factor in dominant follicle development and ovulation. Additionally, differentially expressed genes (DEGs) of SERPINE2 can interact with CYP19A1 to promote cell proliferation, inhibit apoptosis and promoting the anabolism were observed in mouse granulosa cells. Thus, our work provides a comprehensive understanding of the cell-type-specific mechanisms underlying goat ovarian prolificacy at single-cell resolution, provides key insights into offers important clues for improving follicle recruitment in vivo and revealing new diagnostic biomarkers and potential therapeutic targets for ovulation disorder.
