Project description:Identification of skin-expressed genes possibly associated with wool growth regulation in Aohan fine wool sheep
| PRJNA264404 | ENA
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:Background: Sheep are valuable resources for the animal fibre industry. Therefore, identifying genes which regulate 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 compare the gene expression patterns of the body side (hair-rich) and groin (hairless) skins of Aohan fine wool sheep (a Chinese indigenous breed). Results: Comparing the body side to the groin skins (S/G) of Aohan fine wool sheep, the microarray study revealed that 1494 probes were differentially expressed, including 602 more highly expressed and 892 less highly expressed probes. The microarray results were verified by means of quantitative PCR. Cluster analysis could distinguish the body side skin and the groin skin. Based on the Database for Annotation, Visualization and Integrated Discovery (DAVID), 38 of the differentially expressed genes were classified into four categories, namely regulation of receptor binding, multicellular organismal process, protein binding and macromolecular complex. Proteomic study revealed that 187 protein spots showed significant (p < 0.05) differences in their respective expression levels. Among them, 46 protein entries were further identified by MALDI-TOF/MS analyses. Conclusions: Microarray analysis revealed thousands of differentially expressed genes, many of which were possibly associated with wool growth. Several potential gene families might participate in hair growth regulation. Proteomic analysis also indentified hundreds of differentially expressed proteins.

Project description:We have completed the high quality reference genome for domestic sheep (Oar v3.1). Early-stage Illumina GA sequence platform sequenced less reads in high GC content regions than in other regions. To read through higher GC content regions, we generated 2 Gb MeDIP-seq data for filling gaps in sheep reference genome assembly.

Project description:Differential gene expression of hair and wool sheep infected with Haemonchus contortus
| PRJNA112359 | ENA
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 and increasing the yield 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 (more wool growing) in Aohan fine wool sheep (a Chinese indigenous breed) in comparison with groin skin (no wool growing) at the anagen stage of wool follicle. Microarray study revealed that 4772 probes were differentially expressed, including 2071 upregulated and 2701 downregulated probes in the comparisons of body side skin versus groin skin (S/G). The microarray results were verified by means of quantitative PCR. 1099 probes were assigned to unique genes/transcripts. The number of distinct genes/transcripts (annotated) was 926, of which 352 were up-regulated and 574 were down-regulated. In S/G, 13 genes were up-regulated by more than 10-fold, while 60 genes were down-regulated by more than 10-fold. Further analysis revealed that the majority of the genes possibly related to the wool growth could be assigned into the categories including regulation of cell division, intermediate filament, cytoskeletal part and growth factor activity. 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. Proteomic analysis also got 196 differentially expressed protein points, of which 121 were identified as single protein points. 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. One ram and two ewes of 12-month-old Aohan fine wool sheep were used in the microarray study. These animals were half sibs (sharing the same father). In August 2010, two areas of full-thickness skin were sampled from the same animal under local anaesthesia: body side skin (wool bearing) and groin skin (non-wool bearing) for microarray and proteomic experiments. The area of each sample was about 1 cm2. All samples were immediately put into collection tubes and stored in liquid nitrogen for RNA and protein extraction. A total of 15, 208 probes were spotted on this Agilent Sheep Gene Expression Microarray (Santa Clara, CA, USA).
