为了研究肽激素与其质膜受体结合刺激特定基因表达的机制,我们在大鼠垂体细胞系中分析了两种神经内分泌基因——催乳素和生长激素的转录。结果表明,环磷酸腺苷(cyclic adenosine monophospate, cyclic AMP)通过至少两种独立的分子机制刺激真核生物基因的离散亚群的转录。环AMP刺激生长激素基因转录和19000道尔顿核蛋白磷酸化;这似乎反映了环amp依赖性蛋白激酶的直接核作用。相反,环AMP对催乳素基因转录的刺激似乎反映了一个离散的钙依赖性事件的激活。
In experiments designed to study the mechanism by which peptide hormones binding to their plasma membrane receptors stimulate the expression of specific genes, the transcription of two neuroendocrine genes, prolactin and growth hormone, was analyzed in a rat pituitary cell line. The results showed that cyclic adenosine monophosphate (cyclic AMP) stimulates the transcription of discrete subsets of eukaryotic genes by at least two independent molecular mechanisms. Cyclic AMP stimulated growth hormone gene transcription and phosphorylation of a 19,000-dalton nuclear protein; this appears to reflect direct nuclear actions of the cyclic AMP-dependent protein kinase. In contrast, the stimulation by cyclic AMP of prolactin gene transcription appears to reflect activation of a discrete calcium-dependent event.
