Abstract
Hair follicles undergo a renewal cycle consisting of anagen, telogen and catagen stages. MicroRNA (miRNA) plays a crucial role in this process. Recent studies have shown that miR-199a-5p, which exhibits differential expression between anagen and telogen stages in the hair follicle cycle of cashmere goats, inhibits the proliferation of various cell types, including skin keratinocytes and vascular endothelial cells. Since the proliferation of dermal papilla cells (DPCs) is a key factor in the hair follicle cycle, we utilized DPCs to investigate the function and molecular mechanism of miR-199a-5p in cashmere goats. Our functional analysis revealed that miR-199a-5p significantly suppressed cell viability and proliferation of DPCs, as evidenced by MTT, EdU and RT-qPCR methods. Subsequently, we investigated the regulatory mechanism of miR-199a-5p. Through bioinformatics analysis, a potential correlation between lnc102173187 and miR-199a-5p was predicted. However, the dual luciferase reporter assay revealed no interaction between lnc102173187 and miR-199a-5p. Further investigation using dual-luciferase reporter assay, RT-qPCR, and western blot results confirmed that VEGFA was the target gene of miR-199a-5p from. The functional experiment demonstrated that VEGFA promoted the proliferation of DPCs, and antagonized the inhibitory effect of miR-199a-5p on DPCs proliferation. Taken together, this research revealed the role of miR-199a-5p and VEGFA on the proliferation of dermal papilla cells in cashmere goat, which would enrich the theoretical basis for hair follicle development, and could also serve as a marker cofactor to play an important reference and guidance role in the breeding, improvement and optimization of cashmere goat breeds.

Abstract
Increasing Cashmere production can add value because it is the primary product of Cashmere goats. Recent years, peoples find miRNAs are crucial in regulating the development of hair follicle. Following Solexa sequencing, many miRNAs were distinguishingly expressed in telogen skin samples of goats and sheep in earlier study. But the method through which miR-21 controls the growth of hair follicles is still ambiguous. Bioinformatics analysis was used to predict the target genes of miR-21. The mRNA level of miR-21 in telogen Cashmere goat skins was higher than in anagen, according to the results of qRT-PCR, and the target genes expressed similarly with miR-21. Western blot showed similar trend, the protein expression of FGF18 and SMAD7 were lower in anagen samples. The Dual-Luciferase reporter assay confirmed miRNA-21's relationship with its target gene, and the consequences indicated found FGF18 and SMAD7 have positive correlations with miR-21. Western blot and qRT-PCR distinguished the expression of protein and mRNA in miR-21 and its target genes. According to the consequence, we found that target genes expression was increased by miR-21 in HaCaT cells. This study identified that miR-21 might take part in the development of Cashmere goat's hair follicles by targeting FGF18 and SMAD7.

Abstract
Cashmere, a highly valuable animal product derived from cashmere goats, holds significant economic importance. MiRNAs serve as crucial regulators in the developmental processes of mammalian hair follicles. Understanding the regulation of miRNAs during the hair follicle cycle is essential for enhancing cashmere quality. In this investigation, we employed high-throughput sequencing technology to analyze the expression profiles of miRNAs in the secondary hair follicles of Jiangnan cashmere goats at different stages. Through bioinformatics analysis, we identified differentially expressed miRNAs (DE miRNAs). The regulatory relationships between miRNAs and their target genes were verified using multiple techniques, including RT-qPCR, western blot, Dual-Luciferase Reporter, and CKK-8 assays. Our findings revealed the presence of 193 DE miRNAs during various stages of the hair follicle cycle in Jiangnan cashmere goats. Based on the previously obtained mRNA data, the target genes of DE miRNA were predicted, and 1,472 negative regulatory relationships between DE miRNAs and target genes were obtained. Notably, the expression of chi-miR-877-3p was down-regulated during the telogen (Tn) phase compared to the anagen (An) and catagen (Cn) phases, while the IGFBP5 gene exhibited up-regulation. Further validation experiments confirmed that overexpression of chi-miR-877-3p in dermal papilla cells suppressed IGFBP5 gene expression and facilitated cell proliferation. The results of this study provide novel insights for analyzing the hair follicle cycle.

Abstract
Background Arbas Cashmere goats are excellent domestic breeds with high yields of wool and cashmere. Their wool and cashmere can bring huge benefits to the livestock industry. Our studies intend to more fully understand the biological characteristics of hair follicle stem cells (HFSCs) in order to further explore the mechanisms of wool and cashmere regular regeneration. And they have been increasingly considered as promising multipotent cells in regenerative medicine because of their capacity to self-renew and differentiate. However, many aspects of the specific growth characteristics and differentiation ability of HFSCs remain unknown. This study aimed to further explore the growth characteristics and pluripotency of primary hair follicle stem cells (PHFSCs) and secondary hair follicle stem cells (SHFCs). Results We obtained PHFSCs and SHFSCs from Arbas Cashmere goats using combined isolation and purification methods. The proliferation and vitality of the two types of HFSCs, as well as the growth patterns, were examined. HFSC-specific markers and genes related to pluripotency, were subsequently identified. The PHFSCs and SHFSCs of Arbas Cashmere goat have a typical cobblestone morphology. Moreover, the PHFSCs and SHFSCs express HFSC surface markers, including CD34, K14, K15, K19 and LGR5. We also identified pluripotency-associated gene expression, including SOX2, OCT4 and SOX9, in PHFSCs and SHFSCs. Finally, PHFSCs and SHFSCs displayed multipotent abilities. PHFSCs and SHFSCs can be directed to differentiate into adipocyte-like, neural-like, and hepatocyte-like cells. Conclusions In conclusion, this study confirmed that the biological characteristics and differentiation potential of PHFSCs and SHFSCs from Arbas Cashmere goats. These findings broaden and refine our knowledge of types and characteristics of adult stem cells.

Abstract
A subpopulation of Yanshan cashmere goats with crimped fibre has emerged in a closed population in recent years, but little is known about differences in cashmere production performance, skin characteristics, and fibre-style-related genes between goats with different cashmere fibre styles. Therefore, the aim of this study was to investigate fibre characteristics, cashmere yield, hair follicle traits, and fibre-style-related genes in cashmere goats with the two cashmere fleece styles-non-crimped and crimped. Based on the cashmere fibre type, 80 six-month-old female Yanshan cashmere goats were used in this study: 40 goats with non-crimped fleece (NCF) and 40 with crimped fleece (CF). The growth performance and cashmere production of the goats were recorded. Skin samples were collected to determine hair follicle traits and gene sequencing. The results indicated that there were no differences in initial live weight, final live weight, average daily feed intake, and average daily gain between the two groups of goats (P > 0.05). The total yield of cashmere and the stretched length of fibre of the CF goats were higher (P < 0.01 and P < 0.05, respectively) and fibre diameter was lower (P < 0.05) than that of the NCF goats. There were no between-group differences in the density and activity of primary and secondary hair follicles, secondary-to-primary fibre ratio, depth of primary follicles, or epidermal thickness. However, the depth of secondary follicles and dermal thickness were higher (P < 0.05) in NCF goats than in CF goats. There were mutations in the KRT5, KAP8, KRT8, KRT74, KRT34, KRT1, KRT71, KRT6A, KAP6, KRT81, and KRT83 genes, four of which caused amino acid changes. The allele and genotype frequencies of base mutations in the KRT5, KAP8, KRT34, KRT1, KRT6A, KRT81, and KRT83 genes were different in the NCF and CF goats (P < 0.05). The distribution and content of the secondary structure elements and tertiary structures of proteins differed between the wide-type and mutated KRT1 and KRT6A proteins. KRT1, KRT6A, KRT71, and TGFα mRNA expression levels were significantly higher in CF goats than in NCF goats (P < 0.05). It is concluded that cashmere goats that have fleece with crimped fibres produce a greater yield of fleece with finer diameter fibres than those with conventional straight cashmere fibres. These differences in fibre properties may be associated with mutations in the genes coding for KRT1 and KRT6A.

Abstract
Keratin-associated proteins (KAPs) are components of cashmere fibres. The gene encoding the KAP1-3 protein (KRTAP1-3) has been described in goats, but little is known about sequence variation in this gene and if it affects cashmere fibre traits. In this study, we used a polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) technique to screen for nucleotide sequence variation in caprine KRTAP1-3 in 327 Longdong cashmere goats, then analysed association between the genetic variation that was revealed and some cashmere fibre traits. Six PCR-SSCP patterns representing six different variant sequences of KRTAP1-3 (named A to F) were revealed. Among these variant sequences, seven single nucleotide polymorphisms (SNPs) were detected, with two of them being non-synonymous. Goats with genotype AC had higher mean fibre diameter (MFD) than those with genotype AB (P < 0.001), while goats with genotype AB had higher MFD than those with AA (P < 0.001). The presence of C (P < 0.001) and B (P = 0.006) in a genotype was associated with increased MFD, and together this suggests that variation in caprine KRTAP1-3 affects the key fibre trait of MFD.

Abstract
microRNA (miRNA) is a type of endogenous short-chain non-coding RNA with regulatory function found in eukaryotes, which is involved in the regulation of a variety of cellular and biological processes. However, the research on the development of cashmere goat secondary hair follicles is still relatively scarce. In this study, small RNA libraries and mRNA libraries of 45 days, 55 days, 65 days, and 75 days of fetal skin of cashmere goats were constructed, and the constructed libraries were sequenced using Illumina Hiseq4000, and the expression profiles of miRNA and mRNA in cashmere goat fetal skin were obtained. The differentially expressed miRNAs and mRNAs in six control groups were identified and the qRT-PCR experiment shows that the sequencing results are accurate. Sixty-six miRNAs related to secondary hair follicle development were screened, and used TargetScan and miRanda to predict 33 highly expressed miRNA target genes. At the same time, 664 mRNAs related to the development of secondary hair follicles were screened, and GO enrichment and KEGG pathway analysis were performed. It was found that some miRNA target genes were consistent with the screening results of mRNAs related to secondary hair follicle development and were enriched in Notch signaling pathway, TGF-β signaling pathway. Therefore, miR-145-5p-DLL4, miR-27b-3p-DLL4, miR-30e-5p-DLL4, miR-193b-3p-TGF-β1, miR-181b-5p-NOTCH2, and miR-103-3p-NOTCH2 regulatory network related to the development of secondary hair follicles were constructed and the results of dual-luciferase reporter gene assay indicated that there is a targeted relationship between chi-miR-30e-5p and DLL4, which will provide a basis for molecular mechanism of miRNA-mRNA in the development of the hair follicles in cashmere goats.

Abstract
Background Cashmere goat is famous for its high-quality fibers. The growth of cashmere in secondary hair follicles exhibits a seasonal pattern arising from circannual changes in the natural photoperiod. Although several studies have compared and analyzed the differences in gene expression between different hair follicle growth stages, the selection of samples in these studies relies on research experience or morphological evidence. Distinguishing hair follicle growth cycle according to gene expression patterns may help to explore the regulation mechanisms related to cashmere growth and the effect of melatonin from a molecular level more accurately. Results In this study, we applied RNA-sequencing to the hair follicles of three normal and three melatonin-treated Inner Mongolian cashmere goats sampled every month during a whole hair follicle growth cycle. A total of 3559 and 988 genes were subjected as seasonal changing genes (SCGs) in the control and treated groups, respectively. The SCGs in the normal group were divided into three clusters, and their specific expression patterns help to group the hair follicle growth cycle into anagen, catagen and telogen stages. Some canonical pathways such as Wnt, TGF-beta and Hippo signaling pathways were detected as promoting the hair follicle growth, while Cell adhesion molecules (CAMs), Cytokine-cytokine receptor interaction, Jak-STAT, Fc epsilon RI, NOD-like receptor, Rap1, PI3K-Akt, cAMP, NF-kappa B and many immune-related pathways were detected in the catagen and telogen stages. The PI3K-Akt signaling, ECM-receptor interaction and Focal adhesion were found in the transition stage between telogen to anagen, which may serve as candidate biomarkers for telogen-anagen regeneration. A total of 16 signaling pathways, 145 pathway mRNAs, and 93 lncRNAs were enrolled to construct the pathway-mRNA-lncRNA network, which indicated the function of lncRNAs through interacting with their co-expressed mRNAs. Pairwise comparisons between the control and melatonin-treated groups also indicated 941 monthly differentially expressed genes (monthly DEGs). These monthly DEGs were mainly distributed from April and September, which revealed a potential signal pathway map regulating the anagen stage triggered by melatonin. Enrichment analysis showed that Wnt, Hedgehog, ECM, Chemokines and NF-kappa B signaling pathways may be involved in the regulation of non-quiescence and secondary shedding under the influence of melatonin. Conclusions Our study decoded the key regulators of the whole hair follicle growth cycle, laying the foundation for the control of hair follicle growth and improvement of cashmere yield.

Abstract
MiRNAs as a series of small noncoding RNAs that play a crucial part in regulating coat color and hair follicle development. In the previous Solexa sequencing experiments, there were many miRNAs expressed differentially in alpacas with different coat color, including miR-193b.But the mechanism of miR-193b in mammalian pigmentation is still unknown. In this study, bioinformatics analysis showed that WNT10A and GNAI2 might be the target genes of miR-193b. qRT-PCR showed the expression of miR-193b in white Cashmere goats' skins was obviously lower than that in browns, and the expression of WNT10A and GNAI2 were similar with miR-193b. The protein levels of WNT10A and GNAI2 indicated the same findings. Furthermore, the expression of WNT10A and GNAI2 in keratinocytes were analyzed from mRNA and protein levels, the results manifested that the group of overexpression of miR-193b in HaCaT cells increased the expressions of target genes, and miR-193b inhibition group reduced expressions. Luciferase report assays confirmed that the targeting relationship between miR-193b and target genes (WNT10A and GNAI2), the results showed that miR-193b was positively correlated with target genes. These experimental data showed that miR-193b might participate in adjustment of coat color in skin tissue of Cashmere goat by targeting WNT10A and GNAI2.

Abstract
Cashmere, also known as soft gold, is produced from the secondary hair follicles (SHFs) of cashmere goats. The number of SHFs determines the yield and quality of cashmere; therefore, it is of interest to investigate the transcriptional profiles present during cashmere goat hair follicle development. However, mechanisms underlying this development process remain largely unexplored, and studies regarding hair follicle development mostly use a murine research model. In this study, to provide a comprehensive understanding of cellular heterogeneity and cell fate decisions, single-cell RNA sequencing was performed on 19,705 single cells of the dorsal skin from cashmere goat fetuses at induction (embryonic day 60; E60), organogenesis (E90), and cytodifferentiation (E120) stages. For the first time, unsupervised clustering analysis identified 16 cell clusters, and their corresponding cell types were also characterized. Based on lineage inference, a detailed molecular landscape was revealed along the dermal and epidermal cell lineage developmental pathways. Notably, our current data also confirmed the heterogeneity of dermal papillae from different hair follicle types, which was further validated by immunofluorescence analysis. The current study identifies different biomarkers during cashmere goat hair follicle development and has implications for cashmere goat breeding in the future.

Abstract
The Cashmere goat (Capra hircus) is renowned for its high-quality fiber production trait. The hair cycle in Cashmere goat has an annual rhythm. To deepen the understanding of the molecular foundation of annual rhythm in the skin of Cashmere goat, we did a comparative analysis of the Cashmere goat skin transcriptome all year round. 4002 Differentially expressed genes (DEGs) were identified with seasonal variations. 12 months transcriptome were divided into four developmental stages: Jan-Mar, Apr-Jul, Aug-Oct, and Nov-Dec based on gene expression patterns. 13 modules of highly correlated genes in skin were identified using WGCNA. Ten of these modules were consistent with the development stages. The gene function of those genes in each module was analyzed by functional enrichment. The results indicated that Wnt and Hedgehog signaling pathways were inhibited from January to March and activated from April to July. The cutaneous immune system of Cashmere goats has high activity from August to October. Fatty acid metabolism dominates goat skin from November to December. This study provides new information related to the annual skin development cycle, which could provide molecular biological significance for understanding the seasonal development and response to the annual rhythm of skin.

Abstract
MicroRNA plays an important regulatory role in the development of all organisms, including hair follicle development. In order to improve domestic cashmere yield, the role of miRNA in hair follicle cycle has become a research hotspot. However, the molecular and cellular mechanisms by which miRNA-203 regulates hair follicle development are not completely understood. In this study, we found that the relevant target genes of miRNA-203 (DDOST and NAE1) were less expressed in telogen by qPCR and Immunoblotting analysis, contrary to the expression mode of miRNA-203. The Dual-Luciferase reporter assay was used to verify the correlation between miRNA-203 and its target gene expression. The results showed that miRNA-203 specifically binds to the 3 'UTR of DDOST and NAE1, and the expression of miRNA-203 significantly down-regulates the expression of DDOST and NAE1 mRNA and protein. Therefore, this study demonstrates that miRNA-203 may regulate hair follicle development in Cashmere goats by targeting DDOST and NAE1.

Abstract
The objective of the study was to determine the long-term effects of melatonin treatment on cashmere production and hair follicle populations in cashmere goats and their activity in two consecutive cashmere growth cycles. Twenty-four female Inner Mongolian Cashmere goats were randomly allocated to two groups (n = 12), one of which received melatonin implants, the other being an untreated control group. Melatonin implants were subcutaneously inserted behind the ear at a dose of 2 mg/kg live weight on two occasions -April 30 and June 30, 2016. Hair samples were collected by combing in April of 2017 and 2018, and the weight, staple length, and diameter of the cashmere fibers were measured. Blood and skin samples were collected monthly between April and September 2016, and in April and September in 2017 for the analysis of melatonin concentration and the characteristics of secondary hair follicle populations, respectively. The results indicated that serum melatonin concentration in the treated goats was elevated (P < 0.05) relative to that of the control group, but only during the first growth cycle. Melatonin treatment of cashmere goats in one cashmere growth cycle increased the weight, staple length, and density (all P < 0.05) of the cashmere fibers and decreased fiber diameter (P < 0.01), but did not affect the characteristics of cashmere production in the subsequent annual cycle. Melatonin treatment had no effect on the population of skin secondary hair follicles for two consecutive cycles. However, in the first growth cycle after treatment, it advanced the onset of activity of skin secondary hair follicles by 2 mo (P < 0.05), and it increased the number of follicles that were active (P < 0.05). In summary, the melatonin treatment of cashmere goats in one cashmere growth cycle improved cashmere production for that cycle only, with no residual effects on the subsequent cycle, a technique acceptable to the cashmere goat industry. The enhancement of cashmere production after the treatment of goats with melatonin appears to involve the acceleration of the annual regeneration of skin secondary hair follicles and increased population of active secondary hair follicles in the skin of cashmere goats.

Abstract
Astragalus membranaceus (AM) provides a rich source of polysaccharides that can act as powerful antioxidants, but their potential as feed ingredients in the lamb industry still rarely exploited. The objective of this study was to investigate the effect of dietary astragalus membranaceus supplementation on oxidative stability of goat muscles. Longissimus dorsi (LD) muscles from two groups of Cashmere goat (basal diet, C group; basal diet supplemented with 1% astragalus membranaceus root, AM group) were evaluated for lipid oxidation, myoglobin oxidation, activity of antioxidant enzymes, and antioxidant capacity. The results showed that color parameters in Cashmere goat of two feeding conditions were no significant difference (p > .05). In AM group, myoglobin (Mb) content was higher than C, while metmyoglobin (MMb) (p < .05) and malondialdehyde (MDA) (p < .01) were lower. Additionally astragalus membranaceus supplementation had a significant effect on superoxide dismutase (SOD) and catalase (CAT) (p < .001). In whole, the AM group goats presented a relatively higher antioxidant capacity than C. Especially, RSA and CUPRAC values of AM group goats had significantly higher than C (p < .05). Consequently, the AM group goats ingested abundant astragalus membranaceus, which enhanced the antioxidant capacity. Thus, it can eliminate free radicals and effectively inhibit oxidation.

Abstract
This study evaluated the effects of the different dietary zinc (Zn) levels on semen quality, on spermatozoa and seminal plasma antioxidant status, and on the seminal and blood plasma mineral status in mature male Cashmere goats during the breeding season. Twenty-eight mature male Liaoning Cashmere goats were divided into four groups based on body weight (56.2 ± 2.45 kg) and semen characteristics; these goats were fed with basal diet supplemented with 0, 20, 40, or 80 mg Zn/kg DM (zinc sulfate) for 3 months. Results showed that the Zn-supplemented diets linearly increased the semen volume (0.98, 1.04, 1.27, and 1.17 ml for the 0, 20, 40, and 80 mg Zn/kg DM supplementation, respectively) (P < 0.05) and the total sperm output (3.87, 4.52, 5.73, and 5.33 × 109/ml for the 0, 20, 40, and 80 mg Zn/kg DM supplementation, respectively) (P < 0.05); by contrast, Zn supplementation exerted no effect on sperm concentration, motility, and abnormal sperms rate. The activities of copper zinc superoxide dismutase (CuZn-SOD) (linear P < 0.05) and glutathione peroxidase (GSH-Px) (linear P < 0.05; quadratic P < 0.01) were highest in the intermediate supplementation (40 mg Zn/kg DM). Moreover, the malondialdehyde (MDA) content of spermatozoa decreased linearly (P < 0.01) with the increase in Zn supplementation. In seminal plasma, the highest GSH-Px activity was observed in 20 mg Zn/kg DM supplementation (P < 0.05). Catalase (CAT) activities both in the spermatozoa and seminal plasma showed no difference in all treatments. Seminal plasma Zn level was highest in 40 mg Zn/kg DM (linear P = 0.068), and K increased linearly (P = 0.001) with increasing Zn level. Furthermore, blood plasma Zn (linear P < 0.01; quadratic P < 0.05), Fe (linear P < 0.05; quadratic P < 0.05), and Mg (linear P < 0.05) increased with increasing Zn supplementation. These results indicated that dietary Zn supplementation in Cashmere goats during the breeding season improved the semen quality and quantity, elevated the antioxidative indices and Zn concentration, and decreased the MDA content both in spermatozoa and seminal plasma.

Abstract
Background During goat embryonic morphogenesis and postnatal initiation of hair follicle (HF) regeneration, dermal papilla (DP) cells play a vital role in hair formation. Growing evidence shows that microRNAs (miRNAs) participate in HF development and DP cell proliferation. However, the molecular mechanisms have not been thoroughly investigated. Result In this study, we utilized miRNA sequencing (miRNA-Seq) to identify differentially expressed miRNAs at different HF cycling stages (anagen and telogen). MiRNA-Seq has identified 411 annotated miRNAs and 130 novel miRNAs in which 29 miRNAs were up-regulated and 32 miRNAs were down-regulated in the anagen phase compared to the telogen phase. Target gene prediction and functional enrichment analysis indicated some major biological pathways related to hair cycling, such as Wnt signaling pathways, ECM-receptor interaction, VEGF signaling pathway, biosynthesis of amino acids, metabolic pathways, ribosome and oxidative phosphorylation. Also, we explored the function of chi-miR-30b-5p in regulating hair growth cycle. Similar to the HF cycling, DP cells were isolated from skin and used to investigate miRNA functions. The MTT and EdU assays showed that the viability and proliferation of DP cells were inhibited or promoted after the transfection of chi-miR-30b-5p mimic or inhibitor, respectively. Bioinformatics analysis revealed CaMKIIδ as a candidate target gene of chi-miR-30b-5p, and the dual-luciferase and western blot assay demonstrated that chi-miR-30b-5p bound to the 3’UTR of CaMKIIδ and further inhibited its translation. Conclusion Chi-miR-30b-5p was found to be highly expressed in the telogen than that in the anagen phase and could inhibit the proliferation of DP cells by targeting CaMKIIδ. Our study provides new information on the regulatory functions of miRNAs during HF development.

Abstract
BACKGROUND Litter size is the most important reproductive trait which plays a crucial role in goat production. Therefore, improvement of litter size trait has been of increasing interest in goat industry as small improvement in litter size may lead to large profit. The recent Cashmere goat breeding program produced a high-reproductive genetic line of Arbas Cashmere goat. But the genetic mechanism of high reproduction rate remains largely unknown in this Chinese native goat breed. To address this question, we performed a genome-wide association studies (GWAS) using two groups of goats varying in fecundity. OBJECTIVES Our study was aimed to investigate the significant SNPs and genes associated with high reproduction trait in Inner Mongolia Arbas Cashmere Goat. METHODS We used logistic model association to perform GWAS using 47 goats from high fecundity group (~ 190%) and 314 goats from low fecundity group (~ 130%) of the Arbas Cashmere goat breed. RESULTS We identified 66 genomic regions associated with genome wide significant level wherein six loci were found to be associated with reproduction traits. Further analysis showed that five key candidate genes including KISS1, KHDRBS2, WNT10B, SETDB2 and PPP3CA genes are involved in goat fecundity trait. Gene ontology enrichment analysis revealed that several biological pathways could be involved in the variation of fecundity in female goats. CONCLUSIONS The identified significant SNPs or genes provide useful information about the underlying genetic control of fecundity trait which will be helpful to use them in goat breeding programs for improving the reproductive efficiency of goats.

Abstract
Long non-coding RNAs (lncRNAs) is a class of eukaryotic transcripts with length of more than 200 bp. They contribute to the regulation of gene expressions involved in multiple processes including the skin cell proliferation, differentiation, and reconstruction of the secondary hair follicles (SHFs). In this study, firstly, we identified 16 putative lncRNAs from SHFs of cashmere goat based on the EST sequences from NCBI database. Secondly, we investigated their transcriptional pattern in SHFs of cashmere goat, and constructed their ceRNA regulatory networks. The RT-qPCR results showed four lncRNAs (lncRNA-475074, -052149, -052140, and -051789) were significantly up-regulated, and nine lncRNAs (lncRNA-711032, -475083, -475070, -052139, -052127, -052037, -051903, -051847, and -051804) were significantly down-regulatd in anagen SHFs of cashmere goat. CeRNA networks analysis revealed complex interactional relationship among lncRNAs, miRNAs and mRNAs. Further, the KEGG pathway enrichment was performed for the potential target genes of the identified lncRNAs based on bioinformatics technique, and the results indicated that differentially expressed lncRNAs directly or indirectly might regulate potential target genes. Our results from this study will provide a significant information for further exploring the functions and possible mechanisms of the identified lncRNAs in SHFs of cashmere goat.

Abstract
Background Implantation of goats with melatonin can induce cashmere growth and significantly increase cashmere production performance. However, the impact of melatonin implantation on the carcass characteristics, meat quality and related hormone levels in muscle and viscera of cashmere goats has not been studied. This experiment was conducted to determine the effects of melatonin implantation of cashmere goats during the non-growing period on meat quality and related hormone levels in the tissues. It aimed to provide a theoretical basis for the practical application of melatonin in cashmere goat production systems. Results Melatonin implantation (2 mg/kg live weight) had no influence (P > 0.05) on daily weight gain, carcass weight, dressing percentage, loin muscle area, or the pH, moisture level, crude fat (except for Gluteus muscle) and amino acid content of muscles of cashmere goats. After implantation for 1 month, shear force of Longissimus dorsi and water loss rate of Longissimus dorsi and Biceps femoris of cashmere goats were increased (P < 0.05), whereas the cooking yield of Gluteus muscle was reduced (P < 0.05). The melatonin treatment decreased (P < 0.05) muscle crude protein, Gluteus muscle crude fat and ∑n-3PUFA content and decreased (P < 0.05) ∑n-6PUFA content. However, after 2 months of implantation most of these effects had resolved. Melatonin implantation had no effect (P > 0.05) on the melatonin or prolactin contents of kidney, heart, spleen, liver, Longissimus dorsi, Biceps femoris and Gluteus muscles. Melatonin content of lung tissue was lowered (P < 0.05) and that of prolactin was elevated (P < 0.05) by the melatonin implantation. Conclusion This study has shown little impact of melatonin implantation of cashmere goats on carcass quality. A few meat quality indices i.e., shear force, water loss rate, ∑n-3PUFA, ∑n-6PUFA, and crude protein content of Longissimus dorsi; water loss rate, cooking yield and crude protein content of Biceps femoris; ether extract, crude protein content of Gluteus; were affected briefly (at 1 month of implantation) but these effects were not evident after 2 months of implantation. There was little effect of the melatonin treatments on tissue levels of melatonin or prolactin except in lung.

Abstract
This study was designed to identify the relationship of four genes (GDF9, BMPR-IB, FecB and ESR) polymorphisms in the 3'UTR region with litter size and cashmere performance of Liaoning cashmere goats (LCG, n = 1140). The ESR C463T and T575G loci of LCG were genotyped. The results of correlation analysis showed that five effective single nucleotide polymorphisms (SNPs) loci (C47T, C94T, C299T, C463T and T575G) were found in the four genes. The lambing number of CC and CT genotypic individuals at FecB C94T locus was significantly higher than that of TT genotypic individuals (45.7 and 46.8%, respectively); the lambing number of CC genotypic individuals at ESR C463T locus was significantly higher than that of CT, TT genotypic individuals (9 and 15%, respectively); There was a positive correlation between CC genotype at C463T locus and cashmere fineness. In this study, the relationship between FecB C94T and ESR C463T loci C alleles and lambing number in LCG was preliminarily revealed. These results further confirmed that FecB and ESR genes may be significantly correlated with high fecundity of LCG.

Abstract
Background Hair follicles in cashmere goats are divided into primary and secondary hair follicles (HFs). HF development, which determines the morphological structure, is regulated by a large number of vital genes; however, the key functional genes and their interaction networks are still unclear. Although the vitamin D receptor (VDR) is related to cashmere goat HF formation, its precise effects are largely unknown. In the present study, we verified the functions of key genes identified in previous studies using hair dermal papilla (DP) cells as an experimental model. Furthermore, we used CRISPR/Cas9 technology to modify the VDR in DP cells to dissect the molecular mechanism underlying HF formation in cashmere goats. Results The VDR expression levels in nine tissues of Shaanbei white cashmere goats differed significantly between embryonic day 60 (E60) and embryonic day 120 (E120). At E120, VDR expression was highest in the skin. At the newborn and E120 stages, the VDR protein was highly expressed in the root sheath and hair ball region of Shaanbei cashmere goats. We cloned the complete CDS of VDR in the Shaanbei white cashmere goat and constructed a VDR-deficient DP cell model by CRISPR/Cas9. Heterozygous and homozygous mutant DP cells were produced. The growth rate of mutant DP cells was significantly lower than that of wild-type DP cells (P < 0.05) and VDR mRNA levels in DP cells decreased significantly after VDR knockdown (P < 0.05). Further, the expression levels of VGF, Noggin, Lef1, and β-catenin were significantly downregulated (P < 0.05). Conclusions Our results indicated that VDR has a vital role in DP cells, and that its effects are mediated by Wnt and BMP4 signaling.

Abstract
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.

Abstract
Long noncoding RNAs (lncRNAs), a class of non-protein conding RNAs > 200 nt in length, were thought to play critical roles in regulating the expression of protein-coding genes. Here, we identified and characterized a novel lncRNA-000133 from the secondary hair follicle (SHF) of cashmere goat with its ceRNA network analysis, as well as, its potential effects on inductive property of dermal papilla cells were evaluated through overexpression analysis. Expression analysis indicated that lncRNA-000133 had a significantly higher expression at anagen than that at telogen in SHF of Cashmere goat, suggesting that lncRNA-000133 might be involved in the reconstruction of SHF with the formation and growth of cashmere fiber. Taken together with methylation analysis, we showed that 5' regulatory region methylation of the lncRNA-000133 gene might be involved in its expression suppression in SHF of Cashmere goat. The ceRNA regulatory network showed that a rich and complex regulatory relationship between lncRNA-000133 and related miRNAs with their target genes. The overexpression of lncRNA-000133 led to a significant increasing in the relative expression of ET-1, SCF, ALP and LEF1 in dermal papilla cells suggesting that lncRNA-000133 appears to contribute the inductive property of dermal papilla cells.

Abstract
The HOTAIR transcript is transcribed from the antisense strand within the HOXC gene cluster, and it is thought to play a role in regulating the inductive capacity of dermal papilla cells during the reconstruction of hair-follicle. In the current investigation, we firstly isolated and characterized a lncRNA-HOTAIR transcript from the secondary hair follicle of cashmere goat. Also, we analyzed its transcriptional pattern and methylation level of HOTAIR gene promoter in secondary hair follicle of cashmere goat during anagen and telogen stages. Nucleotide composition analysis indicated that the contents of Adenine (A) and Thymine (T) are higher than that of Guanine (G) and Cytosine (C) in lncRNA-HOTAIR transcript of cashmere goat with the highest frequency distribution of AG nucleotide pair (8.06%). The regulatory network analysis showed a directly or indirectly complex regulatory relationships between lncRNA-HOTAIR of cashmere goat and its potential target molecules: miRNAs, mRNAs and proteins. Also, we showed that lncRNA-HOTAIR was properly transcribed at both anagen and telogen stages of secondary hair follicle of cashmere goat with the anagen being significantly higher than telogen in its expression, which suggest that lncRNA-HOTAIR transcript might be involved in the reconstruction of secondary hair follicle with the formation and growth of cashmere fiber. Taken together with methylation analysis of HOTAIR gene promoter, our data suggest that the promoter methylation of HOTAIR gene most likely is involved in its transcriptional suppression in secondary hair follicle of cashmere goat.

Abstract
Inner Mongolia cashmere goat marks a precious gerplasm genetic resource due to its excellent cashmere traits. Therefore, it is of crucial importance to investigate the cashmere development mechanism of cashmere goat and to search for the important cashmere growth-related candidate genes. Fetal skin samples at 10 different periods of cashmere goat were collected in this research. Moreover, high-throughput sequencing was conducted on RNA samples from side skin of cashmere goat fetuses collected at three critical periods of skin hair follicle initiation, growth and development (namely, 45, 55 and 65 days) after balanced mix in line with the previous research results. Meanwhile, 3 samples at corresponding periods were used as the biological duplications. Data regarding microRNA and mRNA expression in skin and hair follicles of cashmere goats at various fetal periods were obtained using the high-throughput sequencing method. The results indicated that microRNAs in the oar-let-7 and oar-miR-200 families in 55 days and 66 days of pregnancy samples had been notably up-regulated relative to those in 45 days of pregnancy samples. This revealed that they might be the critical microRNAs in hair follicle development.

Abstract
Background During hair growth, cortical cells emerging from the proliferative follicle bulb rapidly undergo a differentiation program and synthesize large amounts of hair keratin proteins. In this process, HOXC13 is one critical regulatory factor, proved by the hair defects in HOXC13 mutant mice and HOXC13 mutant patients. However, inconsistent conclusions were drawn from previous researches regarding the regulation of HOXC13 on different keratins. Whether HOXC13 has extensive and unified regulatory role on these numerous keratins is unclear. Results In this study, firstly, RNA-seq was performed to reveal the molecular mechanism of cashmere cycle including anagen and telogen. Subsequently, combining the sequencing with qRT-PCR and immunofluorescent staining results, we found that HOXC13 showed similar expression pattern with a large proportion of keratins except for KRT1 and KRT2, which were higher in anagen compared with telogen. Then, the regulatory role of HOXC13 on different keratins was investigated using dual-luciferase reporter system and keratin promoter-GFP system by overexpressing HOXC13 in HEK 293 T cells and dermal papilla cells. Our results demonstrated that HOXC13 up-regulated the promoter activity of KRT84 and KRT38, while down-regulated the promoter activity of KRT1 and KRT2, which suggested HOXC13 had an ambivalent effect on the promoters of different KRTs. Furtherly, the regulation on HOXC13 itself was investigated. At transcriptional level, the binding sites of HOXC13 and LEF1 were found in the promoter of HOXC13. Then, through transfecting corresponding overexpression vector and dual-luciferase reporter system into dermal papilla cells, the negative-feedback regulation of HOXC13 itself and positive regulation of LEF1 on HOXC13 promoter were revealed. In addition, melatonin could significantly increase the promoter activity of HOXC13 under the concentration of 10 μM and 25 μM by adding exogenous melatonin into dermal papilla cells. At post-transcriptional level, we investigated whether chi-miR-200a could target HOXC13 through dual-luciferase reporter system. At epigenetic level, we investigated the methylation level of HOXC13 promoter at different stages including anagen, telogen and 60d of embryonic period. As a result, miR-200a and methylation were not regulatory factors of HOXC13. Interestingly, we found two SNPs (c.812A > G and c.929A > C) in the homeodomain of HOXC13 that could deprive the regulatory function of HOXC13 on keratins without changing its protein expression. Conclusion HOXC13 had an inconsistent effect on the promoters of different keratins. Two SNPs (c.812A > G and c.929A > C) in the homeodomain of HOXC13 deprived its function on keratin regulation. Besides, the negative-feedback regulation by HOXC13 itself and positive regulation by LEF1 and melatonin on HOXC13 promoter were revealed. This study will enrich the function of HOXC13 on keratin regulation and contribute to understand the mechanism of hair follicle differentiation.

Abstract
Background The growth of Inner Mongolian Cashmere goat skin hair follicle exhibits a periodic growth pattern. The hair growth cycle is distinguished as telogen, anagen, and catagen stages. The role of vimentin in the growth process of hair follicles is evident. To elucidate the mechanism underlying the vimentin activity in the growth cycle of hair follicles, transcriptome sequencing and liquid chromatography-tandem mass spectrometry were used to obtain the nucleic acid and amino acid sequences of VIIM gene and vimentin. The amino acid and nucleic acid sequences were analyzed by comparison. Real-time quantitative PCR, Western blot, and immunohistochemistry analyzed the expression level and sites of vimentin in the three growth stages of the Inner Mongolia Cashmere goat skin samples. Results VIM gene cDNA, obtained by transcriptome sequencing, was aligned against that of the Capra hircus VIM gene. The amino acid sequence of vimentin revealed a high similarity rate across other species. The expressions of both VIM gene and vimentin were highest during the growth period and lowest in the rest period. Furthermore, vimentin was primarily expressed in the outer root sheath of the hair follicle as assessed by staining. Conclusions The sequences of the gene and protein are similar to that of other species and identical to Capra hircus. However, the expression of VIM and vimentin was proportional to that of the growth of hair follicles. And vimentin expressed only in the outer root sheath of hair follicles. Thus, vimentin was speculated to participate in the regulation of the hair follicle growth cycle by affecting the outer root sheath.

Abstract
Background Cashmere growth is a seasonal and cyclic phenomenon under the control of photoperiod and multiple stimulatory and inhibitory signals. Beyond relevant coding genes, microRNA (miRNA) and long non coding RNA (lncRNA) play an indispensable role in hair follicle (HF) development and skin homeostasis. Furthermore, the influence of lncRNA upon miRNA function is also rapidly emerging. However, little is known about miRNAs, lncRNAs and their functions as well as their interactions on cashmere development and cycling. Result Here, based on lncRNA and miRNA high-throughput sequencing and bioinformatics analysis, we have identified 1108 lncRNAs and 541 miRNAs in cashmere goat skin during anagen and telogen. Compared with telogen, 1388 coding genes, 41 lncRNAs and 15 miRNAs were upregulated, while 1104 coding genes, 157 lncRNAs and 8 miRNAs were downregulated in anagen (adjusted P-value ≤0.05 and relative fold-change ≥2). Subsequently, we investigated the impact of lncRNAs on their target genes in cis and trans, indicating that these lncRNAs are functionally conserved during HF development and cycling. Furthermore, miRNA-mRNA and miRNA-lncRNA interaction were identified through the bioinformatics algorithm miRanda, then the ceRNA networks, miR-221-5p-lnc_000679-WNT3, miR-34a-lnc_000181-GATA3 and miR-214-3p-lnc_000344-SMAD3, were constructed under defined rules, to illustrate their roles in cashmere goat HF biology. Conclusion The present study provides a resource for lncRNA, miRNA and mRNA studies in cashmere cycling and development. We also demonstrate potential ceRNA regulatory networks in cashmere goat HF cycling for the first time. It expands our knowledge about lncRNA and miRNA biology as well as contributes to the annotation of the goat genome.

Abstract
Long noncoding RNAs (lncRNAs) are a novel class of eukaryotic transcripts. They are thought to act as a critical regulator of protein-coding gene expression. Herein, we identified and characterized 13 putative lncRNAs from the expressed sequence tags from secondary hair follicle of Cashmere goat. Furthermore, we investigated their transcriptional pattern in secondary hair follicle of Liaoning Cashmere goat during telogen and anagen phases. Also, we generated intracellular regulatory networks of upregulated lncRNAs at anagen in Wnt signaling pathway based on bioinformatics analysis. The relative expression of six putative lncRNAs (lncRNA-599618, -599556, -599554, -599547, -599531, and -599509) at the anagen phase is significantly higher than that at telogen. Compared with anagen, the relative expression of four putative lncRNAs (lncRNA-599528, -599518, -599511, and -599497) was found to be significantly upregulated at telogen phase. The network generated showed that a rich and complex regulatory relationship of the putative lncRNAs and related miRNAs with their target genes in Wnt signaling pathway. Our results from the present study provided a foundation for further elucidating the functional and regulatory mechanisms of these putative lncRNAs in the development of secondary hair follicle and cashmere fiber growth of Cashmere goat.

Abstract
Increasing cashmere yield is one of the vital aims of cashmere goats breeding. Compared to traditional breeding methods, transgenic technology is more efficient and the piggyBac (PB) transposon system has been widely applied to generate transgenic animals. For the present study, donor fibroblasts were stably transfected via a PB donor vector containing the coding sequence of cashmere goat thymosin beta-4 (Tβ4) and driven by a hair follicle-specific promoter, the keratin-associated protein 6.1 (KAP6.1) promoter. To obtain genetically modified cells as nuclear donors, we co-transfected donor vectors into fetal fibroblasts of cashmere goats. Five transgenic cashmere goats were generated following somatic cell nuclear transfer (SCNT). Via determination of the copy numbers and integration sites, the Tβ4 gene was successfully inserted into the goat genome. Histological examination of skin tissue revealed that Tβ4-overexpressing, transgenic goats had a higher secondary to primary hair follicle (S/P) ratio compared to wild type goats. This indicates that Tβ4-overexpressing goats possess increased numbers of secondary hair follicles (SHF). Our results indicate that Tβ4-overexpression in cashmere goats could be a feasible strategy to increase cashmere yield.

Abstract
To determine the relationship between fibroblast growth factor 5 (FGF5) and FGF5-short (FGF5s) in dermal papilla cells of cashmere goat primary and secondary hair follicles. We isolated dermal papilla cells from primary hair follicle (PHF) and secondary hair follicle (SHF) of cashmere goat, and found that the FGF5 receptor, fibroblast growth factor receptor 1 (FGFR1), was expressed in these two types of dermal papilla cells. Moreover, adenovirus-mediated overexpression of FGF5 could upregulate the mRNA expression of insulin-like growth factor-1 (IGF-1), versican and noggin that were important for follicle growth maintenance, whereas downregulate the expression of anagen chalone bone morphogenetic protein 4 (BMP4) in dermal papilla cells. However, these alterations were partly reversed by FGF5s overexpression. In conclusion, our results demonstrated that FGF5s acted as an inhibitor of FGF5 in the regulation of anagen-catagen transition of cashmere goat dermal papilla cells.

Abstract
Background Exogenous melatonin could induce cashmere growth. However, induced growth of cashmere fleece by melatonin implants cannot be combined with the typical growth, resulting in earlier shedding followed by another cycle of cashmere growth. To address this issue, we examine the effects on the cashmere yield, fibre characteristics, and the growth and reproductive performance of cashmere goats of planned administration of melatonin. Methods Eighteen half-sib, female goats were assigned to two treatments (n = 9) including a control and a treatment where melatonin (2 mg/kg BW) was implanted at the end of April and end of June. Cashmere growth and shedding were observed for approximately 1 year following implantation. Fibre samples were collected monthly to determine cumulative cashmere length. Initiation and cessation dates for cashmere growth as well as the rate of cashmere growth were calculated. Cashmere yield, weight gain of dam, kidding date, litter size, and birth weight were also recorded. Results Melatonin implantation increased cashmere yield by 34.5 % (control 553.7 g vs. melatonin 745.0 g; P < 0.01), cashmere length by 21.3 % (control 95.2 mm vs. melatonin 115.4 mm; P < 0.01), and decreased fibre diameter by 4.4 % (control 14.6 μm vs. melatonin 14.0 μm; P < 0.03). In melatonin-treated goats, the average initiation date was earlier than in control goats (May 18, 2013 vs. July 2, 2013; P < 0.01) but there was a similar cessation date (March 22, 2014 vs. March 27, 2014). Consequently, the duration of cashmere growth was longer in melatonin-treated goats than in control goats (307 vs.270 days; P < 0.01). The final BW, average daily gain, kidding date, litter size, and birth weight were not influenced by melatonin implantation. Conclusions These data indicate that melatonin implantation (2 mg/kg BW) on two occasions (late April and June) increased cashmere yield by combining the induced growth of cashmere fleece with the typical growth and decreased the fibre diameter without changing dam growth rate or reproductive performance.

Abstract
Background The physiologic characteristics of the cashmere trait and many of the differentially expressed genes relevant to hair cycling have been extensively studied, whereas genes involved in the prenatal development of hair follicles have been poorly investigated in cashmere goats. The aim of this study, therefore, was to quantify the time-course changes in the expressions of TRα and CRABPII genes in the fetal skin of Chinese cashmere goats at the multiple embryonic days (E70, E75, E80, E90, E100, E120 and E130) using real-time quantitative PCR (RT-qPCR). Results RT-qPCR showed that TRα was expressed at E70 with relatively high level and then slightly decreased (E75, E80, and E90). The highest expression of TRα mRNA was revealed at E130 (P > 0.05). The expression pattern of CRABPII mRNA showed an ‘up-down-up’ trend, which revealed a significantly highest expression at E75 (P < 0.05) and was down-regulated during E80 to E120 (P < 0.05) and mildly increased at E130, subsequently. Conclusion This study demonstrated that TRα and CRABPII genes expressed in different levels during prenatal development of cashmere. The present study will be helpful to provide the comprehensive understanding of TRα and CRABPII genes expressions during cashmere formation and lay the ground for further studies on their roles in regulation of cashmere growth in goats.

Abstract
Lhx2, a member of LIM homeobox transcription factors, plays a key role in normal tissue development. However, the molecular mechanism of Lhx2 gene in the regulation of the secondary hair follicle cycling in cashmere goat remains largely unknown. In the present study, the Lhx2 gene was cloned and characterized in cashmere goat. The cloned cDNA of Lhx2 was 1233 bp in length, encoding for proteins of 406 amino acids which contained all functionally important domains conserved among vertebrate Lhx2 gene. Tissue distribution analysis showed that Lhx2 mRNA was highly expressed in the skin and low expressed in all other tissues. Immunohistochemical localization revealed that Lhx2 was expressed in secondary hair follicles. Analysis of expression profiles of Lhx2 mRNA during different development stages in secondary hair follicles showed that the highest expression was observed at the anagen stage, while the lowest expression was detected at the telogen stage. The expression tendency during the development stages was that it increased from telogen to anagen, decreased from anagen to catagen, and decreased from catagen to telogen. The expression pattern of Lhx2 protein and mRNA was similar. The mRNA and protein expression of Lhx2 were consistent throughout the development cycle in secondary hair follicles. These findings provided a better understanding of the function of Lhx2 and suggested that the cyclic expression of Lhx2 might play important roles during secondary hair follicle development in cashmere goat.
