Abstract

The diverse coat types of cashmere goats significantly influence cashmere yield, yet the regulatory mechanisms mediated by non-coding RNAs (ncRNAs) remain poorly characterized. In this study, we collected skin tissues from two distinct coat types (CHLC_ESA and CHSC_ESA) of The Jinlan Cashmere Goat for transcriptome sequencing analysis. Our findings revealed 130 differentially expressed (DE) lncRNAs and 341 DE mRNAs. GO functional enrichment analysis uncovered some crucial terms such as keratin filament, intermediate filament, cytokine activity, and cytokine receptor binding, along with two pivotal DE lncRNAs: TCONS_00050130 and TCONS_00050142. Furthermore, KEGG pathway analysis identified several important pathways including the Estrogen signaling pathway, Amino sugar and nucleotide sugar metabolism, Adipocytokine signaling pathway, and cytokine-cytokine receptor interaction. Lastly, by constructing a ceRNA regulatory network among DE lncRNAs and DE mRNAs, we identified multiple ceRNA regulatory axes targeting genes such as EPPK1, IRF4, CCL20, and CXCR7. These mechanistic insights not only advance our understanding of ncRNA-mediated hair follicle biology but also provide actionable targets for precision breeding strategies to enhance cashmere quality and yield across caprine species.

摘要

绒山羊多样的被毛类型对羊绒产量有显著影响,然而由非编码RNA(ncRNA)介导的调控机制仍未得到充分表征。在本研究中,我们采集了金岚绒山羊两种不同被毛类型(CHLC_ESA和CHSC_ESA)的皮肤组织进行转录组测序分析。我们的研究结果揭示了130个差异表达的(DE)长链非编码RNA和341个DE信使核糖核酸。基因本体(GO)功能富集分析发现了一些关键术语,如角蛋白丝、中间丝、细胞因子活性和细胞因子受体结合,以及两个关键的DE长链非编码RNA:TCONS_00050130和TCONS_00050142。此外,京都基因与基因组百科全书(KEGG)通路分析确定了几个重要通路,包括雌激素信号通路、氨基糖和核苷酸糖代谢、脂肪细胞因子信号通路以及细胞因子-细胞因子受体相互作用。最后,通过在DE长链非编码RNA和DE信使核糖核酸之间构建竞争性内源RNA(ceRNA)调控网络,我们确定了多个靶向EPPK1、IRF4、CCL20和CXCR7等基因的ceRNA调控轴。这些机制性见解不仅增进了我们对ncRNA介导的毛囊生物学的理解,也为提高山羊绒品质和产量的精准育种策略提供了可操作的靶点。
