Integration Analysis of Hair Follicle Transcriptome and Proteome Reveals the Mechanisms Regulating Wool Fiber Diameter in Angora Rabbits

This study investigated the genetic and protein expression profiles influencing wool fiber diameter in Angora rabbits by integrating transcriptomic and proteomic data from hair follicles. Researchers identified 423 differentially expressed proteins (DEPs) and highlighted key proteins such as KRT10, KRT77, and KRT40, which are involved in processes like keratinocyte differentiation and skin development. The study found a low correlation between mRNA and protein expression, emphasizing the complexity of gene regulation. The findings enhance the understanding of molecular mechanisms underlying wool fiber diameter variation, which is crucial for improving the economic value of rabbit wool and advancing fine-wool Angora rabbit breeding.
