摘  要:
本试验旨在探讨β-catenin和BMP2基因在幼龄水貂皮肤中定量表达的规律及意义。试验选用0~6周龄的幼龄公水貂21只,每周龄各3只,采集背中部的皮肤样品,运用实时荧光定量PCR技术相对定量方法,检测不同周龄的幼龄水貂皮肤中β-catenin和BMP2基因相对表达量的变化。结果显示,随着周龄的增加β-catenin mRNA丰度呈上调趋势,在4周龄时显著增大(P<0.05),5周龄时达最大(P<0.01),6周龄时β-catenin相对表达量与5周龄相比极显著下降(P<0.01);而BMP2mRNA的表达保持稳定(P>0.05)。β-catenin mRNA的丰度与次级毛囊发育变化趋势一致,与前人相关报道一致,提示其可能参与水貂次级毛囊发育;而BMP2mRNA的丰度在毛囊发育阶段变化不明显。

摘  要:
This experiment was designed to investigate the regularity and significance ofβ-catenin and BMP2 mRNA expression in skin of young minks.The mRNA expressions ofβ-catenin and BMP2 in the skin from 0to 6weeks old minks were studied by Real-time quantitative PCR relative quantitative method(ΔΔCt).The dorsocentral region of skin samples were collected from three minks per week.The results showed thatβ-catenin significantly up-regulated at 4weeks old(P<0.05)and reached the maximum at 5weeks old(P<0.01),then compared to 5 weeks old,it extremely significantly decreased at 6 weeks old(P<0.01),while the expression of BMP2 mRNA kept stable with weeks increasing(P>0.05).Combined the results of hair follicle histology of young mink,we could conclude that the abundance ofβ-catenin mRNA was correlated with secondary follicle development.It might be involved in the development of skin and secondary hair follicle in mink,and the abundance of BMP2 did not apparently change at different developmental stages of follicles.
