Article Abstract
Cashmere goats are excellent livestock breeds known for producing high-quality cashmere fibers from secondary hair follicles. In this study, we aimed to explore the key RNA molecules responsible for the differences in cashmere quality between Jiangnan cashmere goats (JNCG) and Changthangi pashmina goats (CPG). Skin transcriptomic data from the anagen, catagen, and telogen stages of hair follicle growth were retrieved from the SRA database for both JNCG and CPG. Bioinformatics analyses were conducted to identify key molecular differences underlying the variation in cashmere fiber quality. The results showed that there were 4,942 differentially expressed genes (DEGs) between JNCG and CPG through differential analysis, and the DEGs were mainly enriched in PI3K-Akt signaling pathway, Thermogenesis, ECM-receptor interaction in KEGG through functional enrichment analysis, and GO entries were mainly enriched in keratin filament, intermediate filament, keratinization. Twenty-four key candidate genes including , , , , , , , , and were further mined through pathways and entries. These genes play an important role in the development of secondary hair follicles and the formation of cashmere quality in cashmere goats, providing a theoretical basis for the genetic improvement of cashmere goats in the future.

CRISPR/Cas9 technology is an efficient tool for site-specific livestock gene editing. However, to minimize potential disruption of host genome function, exogenous genes should be integrated into well-characterized genomic loci, such as H11 or Rosa26, which have been empirically validated for stable transgene expression. This study established a multi-dimensional assessment system to evaluate the biological applicability of the H11 locus and the widely used Rosa26 targeting platform as sites for targeted integration of exogenous genes in goats.

Objective: The Raeini Cashmere goat, native to Kerman Province, Iran, is renowned for its high-quality cashmere fiber, a luxury natural fiber valued for its softness, warmth, and lightweight properties in the textile industry. This breed, adapted to the region's arid climate through long-term natural and artificial selection, supports the local agricultural economy through cashmere, meat, and milk production. This study presents the first whole-genome resequencing dataset for the Raeini Cashmere goat, providing a valuable resource for ecological, evolutionary, and population genomic studies.

Morphogenesis and development of hair follicle fundamentally depend on the interaction between the epidermis and dermis, with dermal papilla cells (DPCs) playing a critical role in these processes. H3K4me3, one of the key histone modifications, is essential for coordinating gene expression. However, the epigenetic modification profile of H3K4me3 in cashmere goat DPCs and its mechanism of action in hair follicle development remain unexplored.

Hair follicle development and cycling are governed by intricate genetic and molecular networks, with microRNAs (miRNAs) playing essential roles as post-transcriptional regulators. In cashmere goats, valued for their fine fiber, miRNAs have emerged as key modulators influencing hair follicle morphogenesis, regeneration, and fiber traits such as fineness and pigmentation. This review highlights recent discoveries in miRNA-mediated regulation of hair follicles, focusing on their dynamic expression patterns and cell-specific functions in keratinocytes, dermal papilla cells, and follicular stem cells.
