Abstract

In cultured rat pituitary cells, glucocorticoids regulate growth hormone production by modulating the number of growth hormone messenger RNA molecules. The effect is quite specific, since only a few other mRNAs are affected by the hormones. This response is demonstrated by assays involving cell-free mRNA translation and cDNA-RNA hybridization. Furthermore, the inducibility by the glucocorticoids is regulated by at least one other class of hormones, thyroid hormone. Thus, this system serves as a model for studying not only the glucocorticoid regulation of specific mRNA, but also the control of this regulation by other factors in the target tissue.

生长激素信使RNA的调控。
在培养的大鼠垂体细胞中,糖皮质激素通过调节生长激素信使RNA分子的数量来调节生长激素的产生。这种影响是非常特殊的,因为只有少数其他mrna受到激素的影响。这种反应是通过无细胞mRNA翻译和cDNA-RNA杂交实验证明的。此外,糖皮质激素的诱导作用受至少另一类激素(甲状腺激素)的调节。因此,该系统不仅可以作为研究糖皮质激素对特定mRNA调控的模型,还可以作为研究靶组织中其他因素对这种调控的控制的模型。
