hair follicle cycle ECM-receptor interaction focal adhesion PI3K-Akt signaling COL1A1 AQP3

TLDR Twelve key genes may improve cashmere production by influencing hair follicle cycles.

The study investigated the genetic mechanisms behind the hair follicle cycle in cashmere goats using weighted gene coexpression network analysis on transcriptome data from 36 skin samples. It identified 10 gene modules, with six significantly related to hair follicle cycle stages such as anagen, catagen, telogen, and late-telogen. Key pathways involved included ECM-receptor interaction, PI3K-Akt signaling, and metabolic processes. Twelve hub genes, including COL1A1 and AQP3, were highlighted as potential markers for enhancing cashmere production. The findings provided insights into the molecular mechanisms of hair follicle growth, potentially aiding in the artificial regulation of cashmere yield.
