摘要: Liaoning cashmere goats are the most precious genetic resources in China. The function of LAMTOR3 [late endosomal/lysosomal adaptor, mitogen-activated protein kinase (MAPK), and mammalian target of rapamycin activator 3/MAPK scaffold protein 1] gene is expressed in the skin of Liaoning cashmere goats. In situ hybridization (ISH) found that LAMTOR3 is expressed in the inner root sheath (IRS) of hair follicles. During the anagen or catagen phase, the expression of LAMTOR3 is higher in secondary hair follicles than in primary hair follicles. Expression of LAMTOR3 in skin cells treated with melatonin or insulin-like growth factor-1 (IGF-1) is lower than in untreated cells. In addition, the simultaneous treatment of fibroblast growth factor 5 and melatonin decrease the expression of LAMTOR3 in skin cells. The simultaneous treatment with melatonin and 10(-5) g/L IGF-1 or 10(-4) g/L IGF-1 increases the expression of LAMTOR3 gene in skin cells. If Noggin expression is decreased, then LAMTOR3 expression is increased. This hypothesis suggested that LAMTOR3 influences the character of cashmere fiber, and it may regulate the development of hair follicle and cashmere growth by inducing the MAPK signaling pathway.
