Abstract

An early response to the administration of oestradiol-17 beta to immature rats is a dramatic stimulation in the synthesis of uterine hnRNA (heterogenous nuclear RNA). High-molecular-weight fractions of the hnRNA were purified and subfractionated on poly(U)-Sepharose into fractions that differed in their poly(A) content and their size profile on polyacrylamide gels. Oestrogen treatment of the rats stimulated the synthesis of all three fractions of high-molecular-weight hnRNA, but the kinetics of synthesis, degree of stimulation and size distribution of the newly synthesize RNA differed in each fraction.

摘要

给未成熟大鼠注射17β-雌二醇后的早期反应是子宫hnRNA(不均一核RNA)合成受到显著刺激。对hnRNA的高分子量部分进行纯化,并在聚(U)-琼脂糖上进行亚分级分离,得到在聚(A)含量和聚丙烯酰胺凝胶上的大小分布方面存在差异的级分。用雌激素处理大鼠刺激了所有三个高分子量hnRNA级分的合成,但新合成RNA的合成动力学、刺激程度和大小分布在每个级分中都有所不同。
