摘要:

本研究旨在探讨内皮素3在绵羊皮肤毛色中的作用。采用实时荧光定量PCR、Western blotting和免疫组织化学对内皮素3在黑色和白色绵羊皮肤中的表达差异进行分析。实时荧光定量PCR结果显示,内皮素3在黑色绵羊皮肤中的相对表达量较高,是其在白色绵羊皮肤中的表达量的2.89倍,且差异极显著(P<0.01);Western blotting结果显示,内皮素3在黑色绵羊皮肤总蛋白中的表达量极显著高于其在白色绵羊皮肤总蛋白中的表达量(P<0.01);免疫组织化学结果表明,内皮素3在白色绵羊皮肤毛囊的毛乳头上方、毛球底部及外根鞘呈阳性表达,而在黑色绵羊皮肤毛囊的毛球底部和部分外根鞘呈阳性表达。综上表明,内皮素3可能参与绵羊毛色形成。

Abstract:

To investigate the function of endothelin 3(Edn3) in sheep skins and the regulation of hair color formation,the differential expression of Edn3 in skins of black versus white sheep was examined.Quantitative real-time PCR(qRT-PCR),Western blotting and immunohistochemistry methods were performed.The results showed that the quantity expression of Edn3 mRNA in black sheep was 2.89 times than in white sheep(P<0.01);the average protein expression of Edn3 in black sheep skin was higher than in white sheep skin on the optical density(P<0.01).The results of immunohistochemistry revealed that Edn3 was localized in the hair dermal papilla,lower of hair bulb and outer root sheath in hair follicles of sheep with white hair color,but was localized in lower of hair bulb and outer root sheath in hair follicles of sheep with black hair color.The differential expression and localization of Edn3 in skin of white versus black sheep suggests a potential role in hair color regulation.
