摘要: 为探讨β-catenin在人工诱导发情绵羊子宫组织中的表达情况,本试验采用实时荧光定量PCR与半定量PCR检测绵羊发情后第10、12、14、16、18天子宫组织中β-cateninm RNA的表达情况。实时荧光定量PCR与半定量PCR结果显示:两种检测方法均能检测出不同时期的绵羊子宫中β-catenin mRNA表达,且在发情后10~18天均呈现出先减少后增加的变化趋势,其中绵羊发情后第10天β-catenin mRNA的相对表达量最大,显著高于其他4个时间点(P<0.05),第12天相对表达量显著降低(P<0.05),之后相对保持恒定,到第18天又显著升高(P<0.05)。结论:实时荧光定量PCR与半定量PCR均可用于检测绵羊子宫组织中β-catenin mRNA的相对表达量;在绵羊发情后第10~18天,β-catenin在子宫中的呈现先减少后增加的波动变化趋势。

Abstract: To investigate the changes in the expression of β-catenin in uterus of oestrous sheep which was artificially induced, expression changes of β-catenin on the 10th, 12th, 14th, 16th and 18thday after sheep oestrus were detected respectively by Real-Time PCR and semi-quantitative PCR. Real-time quantitative and semi-quantitative PCR results showed that: two detection methods could detect mRNA expression in sheep uterus in different periods of β-catenin, and in 10th to 18th days were shown to decrease after increasing trend. The transcriptional level of β-catenin on the 10th day was significantly higher than that of the other days (P<0.05). In addition, β-catenin mRNA expression on the 12th day reduced significantly (P<0.05), and then remained relatively constantly, but significantly increased on the 18th day (P<0.05). Real-time PCR and semi-quantitative PCR can be used to detect the relative expression level of sheep uterine tissue of β-catenin mRNA; during the 10th to 18th day after sheep oestrus, the transcriptional level of β-catenin presented a decrease-increase trend.
