September 2025 in “Animals” In this study, researchers using Astral—DIA proteomics technology identified 67 differentially expressed proteins in Gansu alpine fine-wool sheep, linking proteins like keratin and MGST3 in pathways to wool fineness regulation, particularly highlighting their association with hair follicle development.
January 2025 in “BMC Genomics” This study examined the role of long non-coding RNAs in wool fineness among Gansu alpine fine-wool sheep, identifying specific lncRNAs and target genes that may enhance wool quality.
September 2023 in “Animals” In this study, researchers conducted whole-genome resequencing of eight sheep breeds to identify additional genes associated with wool fineness, revealing 269 genes in fine wool and 319 in coarse wool breeds that are linked to significant traits and pathways.

June 2024 in “Frontiers in Genetics” This study analyzed RNA-seq data from various animal breeds and suggested that similar molecular mechanisms may underlie wool fineness in different sheep breeds. Researchers identified 32 candidate genes related to hair follicle regulation, providing insights for molecular breeding and evolutionary studies.
January 2012 in “Heilongjiang xumu shouyi” This study found that EGF and KGF were expressed at different levels in the skin of Gansu alpine Merino sheep, suggesting these factors influence wool fineness.
