Abstract  To detect the gonadotropin releasing hormone receptor  (GnRHR)  mRNA expression pattern in sheep’s digestive system, the SYBR green realtime fluorescence quantitative polymerase chain reaction  (RTPCR)method was established With this method, the  GnRHR  mRNA expression in stomach and intestinum system of Hu sheep was detected The results showed that GnRHR mRNA expressions were detected in rumen, reticulum, omasum, abomasums, duodenum, jejunum, ileum, caecum, colon and rectum The GnRHR mRNA expression in rumen was significantly higher than those in other tissues (P<001); the expression in reticulum was significantly higher than that in duodenum  (P<001)  and  higher than those in omasum, caecum and rectum (P<005); the expression in abomasums was significantly higher than  those in omasum, jejunum, ileum and caecum (P<001),  and higher than  those in colon, rectum (P<005); the expression in colon was  higher than  those in  duodenum and rectum (P<005) It is demonstrated that there are GnRHR mRNA expressions in the digestive system of Hu sheep It provides new evidences for the research field of GnRH functional diversity

湖羊促性腺激素释放激素受体基因(GnRHR)在消化系统中的表达谱分析

建立湖羊促性腺激素释放激素受体(gonadotropin releasing hormone receptor, GnRHR)基因的实时荧光定量聚合酶链反应(RTPCR)检测方法,并采用该方法对湖羊消化系统中胃肠各组织的GnRHR mRNA表达水平进行检测。结果表明:GnRHR  mRNA在瘤胃、网胃、瓣胃、皱胃、十二指肠、空肠、回肠、盲肠、结肠和直肠部位均有表达,其中瘤胃GnRHR mRNA表达量最高,极显著高于其他各组织(P<0.01);网胃GnRHR  mRNA表达量极显著高于十二指肠(P<001),显著高于瓣胃、盲肠和直肠(P<005);皱胃GnRHR mRNA表达量极显著高于瓣胃、空肠、回肠和盲肠(P<001),显著高于结肠和直肠(P<005);结肠GnRHR mRNA表达量显著高于十二指肠和直肠(P<005)。研究证实了GnRHR  mRNA 在湖羊消化系统中有表达,这为GnRH功能的多样性研究提供了新的依据。
