| 1 | Hoxc13/β-catenin Correlation with Hair Follicle Activity in Cashmere Goat显示文摘Seasonal hair follicle activity and fibre growth in some Cashmere-bearing goats (Caprus hircus) is a cyclic process that is well characterized morphologically but understood incompletely at the molecular level. As an initial step in discovering regulators in hair-follicle activity and cycling, we used qPCR to investigate 19 genes expression in Cashmere goat side skin from 12 mon. Many of these genes may be associated with the hair follicle development-relevant genes (HFDRGs) in the literature. Here we show that Hoxc13/β-catenin gene associated with the follicle activity. In addition, Hoxc13 was found to be expressed with an drastic increase between July and November for melatonin treatments. To further investigate the role of Hoxc13 on HFDRGs, fibroblasts and keratinocytes from Cashmere goat skin were transfected with p-ECFP- Hoxc13. The result suggested that overexpression of Hoxc13 gene decreased HFDRGs with negative role for hair follicle development and increase HFDRGs with positive role for hair follicle development in vitro. These findings provide data on the Hoxc13 expression profile of normal Cashmere goat skin and Cashmere goat skin with melatonin treatment, and demonstrate hair-follicle-activity dependent regulation of Hoxc13 expression. | WU Jiang-hong ZHANG Yan-jun ZHANG Jia-xin CHANG Zi-li LI Jin-quan YAN Zu-wei Husile ZHANG Wen-guang | 2012 | Journal of Integrative Agriculture2012，11，7： | 10 |
