Differential Gene Expression Analysis Between Anagen and Telogen of Capra Hircus Skin Based on the De Novo Assembled Transcriptome Sequence

In this study, researchers sequenced and assembled the goat skin transcriptome during the anagen and telogen phases of the hair growth cycle using Illumina/Solexa technology, resulting in 53Mb of sequences and 57,040 high-quality contigs. They identified approximately 7000 differentially expressed genes between the two phases, with significant enrichment in signal transduction, extracellular structures, and cytoskeleton-related genes. These genes were crucial for cell communication during active hair growth. The findings highlighted the importance of signaling pathways in hair growth and provided valuable insights for improving Cashmere goat breeding.
