Yangtze River Delta white goat is an exclusive indigenous Chinese goat breeds that can produce Brush Hair specialized in making valuable writing brush. The high-grade (Type III) Brush Hair is conical coarse hair but with a tip, which only grows in the cervical carina and back regions of Yangtze River Delta white goats. Screening of genes influencing the formation of Type III Brush Hair was conducted using differential display of mRNA technique in skin including the hair follicles of different goat groups and the differential bands were identified using reverse Northern dot blot, and the positive bands were subsequently cloned and sequenced. The results showed that 20 differentially displayed bands were obtained, seven of which were identified positive as expressed in skin. Three of these seven cDNAs were homologous to certain sequences from GenBank and the other four were respectively homologous to CKLF-like MARVEL transmembrane domain containing 3 (CMTM3), S100 calcium binding protein A4 (S100A4), protein kinase inhibitor gamma (PKIG) and fibulin 1-D. The study would provide a new view to elucidate their roles in hair growth and hair follicle cycle and increase our understanding of the formation of Type III Brush Hair.
