Project description:We performed a genome-wide analysis of mRNAs and lncRNAs from Small Tail Han sheep of genotypes FecBBFecBB (Han BB) and FecB+ FecB+ (Han++) and from Dorset sheep (Dorset) to identify potential regulators of fecundity. An integrated analysis revealed significantly correlated patterns of expression. Dramatic changes of mRNAs and lncRNAs suggest their critical roles in sheep fecundity. This study provides a novel view of the regulatory mechanisms involved in sheep fecundity.

Project description:In this study, we selected differentially expressed miRNAs through construcing and analyzing the miRNA expression profile during 2-, 6-, and 12- month-old Small Tail Han Sheep ovaries, which provided a theoretical basis for the study of miRNAs regulating the reproduction of Small Tail Han Sheep. RNASeq techniques were used to perform profile analysis for these ovaries. The results showed that 11, 13 and 19 DE miRNAs were identified in 2- vs 6-, 6- vs 12-, and 2- vs 12-month-old ovaries, respectively. In total, 54, 37, and 198 predicted target genes of DE miRNAs were obtained from these three groups, respectively. GO and KEGG analyses showed that, in 2- vs 6-month-olds, the target genes of DE known sheep miRNAs were involved in 102 GO terms and 7 signaling pathways; in 6- vs 12-month-olds, the target genes of DE known sheep miRNAs were involved in 52 GO terms and 3 signaling pathways; and in 2- vs 12-month-olds, the target genes of DE known sheep miRNAs were involved in 88 GO terms and 6 signaling pathways. Three miR–target regulatory networks were constructed based on these DE miRNA–targets. 9 miRNAs were selected to validate the accuracy of miRNA sequencing data by qRT-PCR. The binding sites of oar-miR-432 with RPS6KA1 was validated by a dual luciferase reporter gene detection system. This is the first integrative analysis of miRNA and mRNA expression profiles in Small Tail Han Sheep ovarian development. These data help elucidate the molecular regulatory mechanisms in sheep ovarian development and identify the biomarkers that influence reproductive performance of Small Tail Han Sheep ewe.

Project description:We report the application of High throughout sequencing to explore the differences of skin between Super Merino sheep(SM) and Small Tail Han sheep, which have remarkable phenotype differences on wool and hair follicle traits. We analysed the expression data by CLC genomic workbench 9.0 software. We find there are 435 differential expressional genes (DEGs) (127 were up-regulated and 308 were down-regulated) when STH sheep as control group. Some hair follicle KRTs, KAPs genes and hair follicle stem cells marker genes, were up-regulated in SM sheep. However, some of mammalian epidermal development complex (EDC) family genes were up-regulated in STH sheep. The GO and gene network analysis shown high expression genes in SM sheep enriched on type I interferon, lipid/fatty acid synthesis metabolism. This study provide more details in skin which control the development of follicle and wool in sheep.

Project description:Sheep provide considerable materials for the animal fibre industry. Identifying genes of major effect for wool growth would offer strategies for improving the quality of fine wool. In this study, we employed Agilent Sheep Gene Expression Microarray and proteomic technology to investigate the gene expression patterns of body side skin between Aohan fine wool sheep and small tail Han sheep (two Chinese indigenous breed) at the anagen stage of wool follicle. Several potential gene families might participate in hair growth regulation, including fibroblast growth factors, transforming growth factor-β, WNTs, insulin-like growth factor, vascular endothelial growth factors and so on. Furthermore, according to the results at both mRNA and protein levels, similar regulation mechanism of gene activity might be engaged during skin development and embryo development.

Project description:The semen of Small Tail Han Sheep has characteristics of high yield, high density, and good motility. To reveal the key miRNAs, mRNAs and miR-Targets regulatory mechanisms in Small Tail Han Sheep testes development, integrated analysis of miRNA and mRNA expression profiles in 2-, 6-, and 12-month-old testes were investigated by RNA-seq technology and bioinformatics methods. As the results shown: 630, 102, and 322 differentially expressed (DE) mRNAs; 5, 1 and 4 DE known miRNAs; 132, 105 and 24 DE novel miRNAs were identified in 2- vs 6-month-old, 6- vs 12-month-old, and 2- vs 12-month-old testes, respectively. GO and pathway analysis showed: in 2- vs 6-month-old testes, DE mRNAs were mainly involved in sexual maturation process and the DE mRNAs were mainly involved in multiple metabolism and biosynthesis pathways; in 6- vs 12-month-old testes, DE mRNAs were mainly involved in metabolism and translation processes, and the most significant pathway that DE mRNAs involved in was ribosome pathway; in 2- vs 12-month-old testes, DE mRNAs were mainly involved in metabolism and physiological processes, and DE mRNAs were mainly involved in multiple metabolism and biosynthesis pathways. Subsequently, 76, 11 and 1 DE miR-Targets were identified in 2- vs 6-month-old, 2- vs 12-month-old, and 6- vs 12-month-old testes, respectively. 3 miR-Target regulatory networks were constructed based on these miR-Targets, which helped to elucidate the regulatory metabolism in Small Tail sheep testes development. Finally, 6 miRNAs and 7 mRNAs were selected to validate the RNA-seq data by RT-PCR.

Project description:Chinese indigenous sheep can be classified into two types according to their tail morphology: fat-rumped and thin-tailed sheep, of which the typical breeds are Altay sheep and Tibetan sheep, respectively. To identify the differentially expressed proteins (DEPs) underlying the phenotypic differences between tail types, we used iTRAQ combined with multi-dimensional liquid chromatography tandem mass spectrometry (LC-MS/MS) technology to detect candidate proteins. We then subjected these to a database search, and identified the DEPs. Finally, bioinformatics technology was used to carry out GO functional and KEGG pathway analyses. A total of 3248 proteins were identified, of which 44 were up-regulated and 40 were down-regulated DEPs. Analyzing their GO function terms and KEGG pathways revealed that the functions of these DEPs are mainly binding, catalytic activity, structural molecule activity, molecular function regulator, and transporter activity. Among the genes encoding the DEPs, APOA2, GALK1, ADIPOQ, and NDUFS4 are associated with fat formation and metabolism.
