Study on the Skin Structure, Hair Follicle Cycle, and GSDMA Protein Expression in Ganxi Goats

The study on Ganxi goats examined their skin structure, hair follicle cycles, and GSDMA protein expression, revealing adaptations to hot and humid climates. Researchers analyzed skin samples from 10 female goats over a year, finding unique structural features like looser hair follicle groups and well-developed sweat glands that aid in heat dissipation. The hair follicle cycle was divided into four phases, with GSDMA protein expression peaking in late anagen and varying monthly. These findings suggest that GSDMA may regulate the hair follicle cycle and maintain skin homeostasis, contributing to the goats' environmental adaptation and offering potential markers for breeding programs to enhance climate resilience.
