Project description:we evaluated the Arbas Cashmere goat, a species that is especially used in this type of research. The goats were exposed to an experimentally controlled short photoperiod to study the regulation of cyclical cashmere growth. Exposure to a short photoperiod extended the anagen phase of the Cashmere goat hair follicle to increase cashmere production. Based on assessments of tissue sections, it was observed that the short photoperiod significantly induced cashmere growth. A comparison of the differences in gene expression between the short photoperiod and the natural conditions using gene chip technology supported this conclusion. Using the gene chip data, we identified genes that showed altered expression under the short photoperiod compared to natural conditions, and it was found that these genes are involved in the biological processes of hair follicle growth, structural composition of the hair follicle, and the morphogenesis of the surrounding skin appendages.

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.

Based on their similar weights, health conditions and good reproductive performance in a group of the same strain, we chose 62-year-old female adult Arbas Cashmere goats as our research specimens and randomly divided them into a test group (T1, T2, T3) and a control group (C1, C2, C3).The goats in the test group were grazed, fed, and allowed to drink from 9:30-16:30 daily, and they were housed in a dark shed with good air conditions for the rest of the time. The temperature in the shed was 1 degree less than that outside, and the opacity was controlled at approximately 0.1 lux. The control group was grazed in natural conditions. We used regular management to care for all of the goats.

Project description:The study confirmed a batch of goat skin and hair follicles miRNA, by high-throughput sequencing methods.316 sequences miRNAs were obtained by the means of analysis and we confirmed the authenticity of 68 known miRNAs and discovered 248 novel miRNAs, as well as 22 miRNAs that havenM-bM-^@M-^Yt been reported before. Through the miRNAs family analysis, we found the co-expressed miRNAs in goat and sheep located in the same region of chromosome, which may play an essential role in skin and follicle development. In addition, the prediction of novel target miRNAs followed by the analysis of target gene pathways indicated that MAPK pathway may have an important effect to the fast growth of skin follicle cell. We sequenced a mixed sample which contains three goat skin in anagen of cashmere

Project description:Cashmere, also known as soft gold, is produced from secondary hair follicles in Cashmere goats and it’s therefore of significance to investigate the molecular profiles during Cashmere goat hair follicle development. However, our current understanding of the machinery underlying Cashmere goat hair follicle remains largely unexplored and researches regarding hair follicle development mainly used the mouse as a research model. To provides comprehensively understanding on the cellular heterogeneity and cell lineage cell fate decisions, we performed single-cell RNA sequencing on 19,705 single cells from induction (embryonic day 60), organogenesis (embryonic day 90) and cytodifferentiation (embryonic day 120) stage fetus Cashmere goat dorsal skin. Unsupervised clustering analysis identified 16 cell clusters and their corresponding cell types were also successfully characterized. Based on cell lineage inference, we revealed detailed transcriptional gene expression profiles during dermal and epidermal lineage cell fate decisions. These works together delineate unparalleled molecular profiles of different cell populations during Cashmere goat hair follicle morphogenesis and provide a valuable resource for identifying biomarkers during Cashmere goat hair follicle development.

Project description:Guard hair and cashmere undercoat are developed from primary and secondary hair follicle, respectively. Little is known about the gene expression differences between primary and secondary hair follicle cycling. In this study, we obtained RNA-seq data from cashmere and milk goats grown at four different seasons. We studied the differentially expressed genes (DEGs) during the yearly hair follicle cycling, and between cashmere and milk goats. WNT, NOTCH, MAPK, BMP, TGFβ and Hedgehog signaling pathways were involved in hair follicle cycling in both cashmere and milk goat. However, Milk goat DEGs between different months were significantly more than cashmere goat DEGs, with the largest difference being identified in December. Some expression dynamics were confirmed by quantitative PCR and western blot, and immunohistochemistry. This study offers new information sources related to hair follicle cycling in milk and cashmere goats, which could be applicable to improve the wool production and quality.
