敖汉细毛羊Ⅰ型内根鞘角蛋白基因表达模式的研究分析
Genechip Analysis of Type Ⅰ IRS Keratin Expression Pattern in Aohan Wool Sheep
摘要
Abstract
[Objective] The paper was to study the expression pattern of specific genes during wool anagen and telogen and it significance to Aohan wool sheep breeding, [ Method ] Mieroarrays were used to detect the expression of different genes between neck and groin during stages of anagen and telogen in Aohan wool sheep. [Result] The expression of type I IRS keratin genes KRT15, KRT26, KRT27 and KRT28 in neck and groin of wool sheep were statistically analyzed, and the result showed that the expression in neck during anagen stage was significantly higher than that in groin( The multiple is more than 2 times, P < 0. 01). The expression changes of the gene during stages of anagen and telogen were compared, and the results showed that the expression of all Type I IRS Keratin genes performed in groin showed significant decrease from anagen stage to telogen stage ( P < 0. 05 ) , the expression changes of other gene were two times higher, except KRT25 (LDC443079). [Conclusion] The result indicated that the expression of type [ IRS Keratin genes had important link with control of wool density in specific part and the whole wool development cycle.关键词
