摘要: 为了研究褪黑激素(melatonin,MT)对绒山羊皮肤毛囊基因表达的影响,筛选与皮肤毛囊发育相关的重要基因.选取处于皮肤毛囊发育生长起始点(5月)的内蒙古绒山羊罕山型个体6只,分别作为埋植组(皮下埋植MT,n=3)和对照组(不埋植MT,n=3),以绒山羊个体皮肤组织为试验材料,对其进行RNA—Seq测序,利用生物信息学方法对转录组数据进行分析.在测序数据质量控制的基础上,对差异表达基因进行筛选、功能注释和富集分析。结果表明,共筛选获得了462个在埋植组与对照组中差异表达的基因,其中,上调表达208个,下调表达254个;KEGG富集性分析表明差异表达基因主要参与:代谢途径、不饱和脂肪酸生物合成、脂肪酸代谢、癌症信号通路、鳞状细胞癌信号通路、黑色素合成、Wnt信号通路以及补体和凝血级联反应等,Wnt信号可能在褪黑激素调控皮肤毛囊发育中发挥重要作用.、研究结果为进一步阐明褪黑激素影响毛囊生长的分子机理提供了依据。

Abstract: In order to investigate the effects of melatonin on genes expression and to find the functional genes related to hairfollicle development, six five-month-old Inner Mongolia Hanshan Cashmere goats were selected and divided equally andrandomly into two groups, melatonin implantation group (MT) and non-implantation group (CK). Taking the skin tissue of thegoats as experimental material, RNA-Seq was performed to analyze the transcriptome data by bioinformatics methods. On thebasis of quality control of raw sequencing data, differentially expressed genes (DEGs) were identified, and functional annotationand enrichment analysis were carried out. The results showed that a total of 462 DEGs were screened out, among which, 208 wereup-regulated while 254 were down-regulated. The results of KEGG pathway enrichment analysis elucidated that DEGs aremainly involved in the metabolic pathways, unsaturated fatty acid biosynthesis, fatty acid metabolism, cancer pathways, squamouscell carcinoma pathways, melanogenesis, Wnt signaling pathway and complement and coagulation cascades. Additionally, Wntsignaling pathway may play an important role in melatonin regulation of hair follicle development. This study will provide a basisfor further study on the eftect of melatonin on hair follicle development.
