摘 要: 根据大鼠脑型一氧化氮合酶(bNOS)和内皮型一氧化氮合酶(eNOS)的cDNA序列分别设计特异引物,用逆转录聚合酶链反应(RT-PCR)方法检测2种NOS在脑、肝脏和前列腺中的mRNA表达差异。结果表明:bNOS在小脑、大脑皮质和海马中有表达,并且在肝脏和前列腺组织中也有表达:eNOS在肝组织中有表达,在小脑、大脑皮质和海马等脑组织中均有表达,但前列腺组织中未检测到mRNA表达。2种NOS在上述组织中的广泛分布提示NO具有多种复杂的、有时甚至是相反的生理功能可能与bNOS和eNOS甚至诱导型一氧化氮合酶(iNOS)分别或共同作用有关。 The specific primers of bNOS and eNOS were designed depending on the cNOS cDNA sequence.The mRNA expression of both bNOS and eNOS in rat brain,liver and prostate was demonstated by RT PCR.The results showed that bNOS mRNA existed not only in cerebral cortes,hippocampus and cerebellum but also in liver and prostate.eNOS mRNA also distributed extensively in above mentioned tissues except prostate.These data suggested that the complicated,sometimes even paradoxical functions of NO in cells may be the allied effect of bNOS and eNOS,as well as inducible NOS.
