摘要: 试验旨在研究不同品种绵羊皮肤毛囊中角蛋白关联蛋白8-1(keratin associated protein 8-1,KAP8-1)基因相对表达量,从而明确KAP8-1基因对绵羊皮肤毛囊发育的调控作用。采用Real-time PCR SYBR GreenⅠ染料法,测定KAP8-1基因荧光定量Ct值,所得结果采用2-△△Ct法计算相对表达量。结果表明,南非肉用美利奴羊(♂)×东北细毛羊(♀)组、南非肉用美利奴羊(♂)×小尾寒羊(♀)组、杜泊羊(♂)×小尾寒羊(♀)组3个品种羊皮肤毛囊内KAP8-1基因均有表达,且三者相对表达量的比值为7.56∶2.19∶1。说明KAP8-1基因对皮肤毛囊发育、羊毛品质差异均具有一定的调控作用,且品种之间存在一定的差异。

Abstract: Relative expression of keratin associated protein 8-1 (KAP8-1)gene was determined in different vrieties of Ovis aries skin and hair follicle so as to identify the regulation of KAP8-1 gene on skin and hair follicle development and wool quality difference. Using Real-time PCR SYBR GreenⅠ, Ct of expression of KAP8-1 gene was determined and relative expression of KAP8-1 gene was analyzed by 2-△△Ct. The results showed that there was KAP8-1 gene expression in there different crossbred varieties of Ovis aries (South African mutton Merino sheep(♂)× Northeast Fine wool sheep(♀),South African mutton Merino sheep(♂)× Small-tailed Han sheep(♀),Dorper sheep(♂)× Small-tailed Han sheep(♀)) skin and hair follicle. The ratio of relative expression was 7.56∶2.19∶1. In a word, KAP8-1 gene played a role in regulating skin and hair follicle development and wool quality difference,with difference among different varieties.
