单次注射雌二醇 (E2) 会在大约 24 小时后导致子宫腔上皮中 DNA 合成的最大增加。我们之前报道过,在第一次注射后 15-18 小时接受第二次 E2 注射的动物在 24 小时时测量到该细胞类型的 DNA 合成明显减少。 DNA 合成的这种明显减少是由于 DNA 合成时间过程的变化,而不是该参数的绝对减少。在本报告中,我们证明了在管腔内滴注激素后也观察到了第二次注射 E2 的抑制作用。这种效应是剂量依赖性的,并且似乎是由于管腔上皮 DNA 合成的时间过程的变化造成的。 E2 的腔内滴注产生与皮下注射激素相同的核受体定位模式。这些结果表明,我们之前描述的这种抑制作用主要来自 E2 对管腔上皮的直接作用。
Administration of a single injection of estradiol (E2) causes a maximum increase in DNA synthesis in the uterine luminal epithelium approximately 24 h later. We previously reported that animals receiving a second injection of E2 15-18 h after the first show an apparent decrease in DNA synthesis measured in this cell type at 24 h. This apparent decrease in DNA synthesis is due to a shift in the time course of DNA synthesis rather than an absolute decrease in this parameter. In this report we demonstrate that this inhibitory effect of a second injection of E2 is also observed after intraluminal instillation of the hormone. This effect is dose dependent and appears to result from a shift in the time course of luminal epithelial DNA synthesis. The intraluminal instillation of E2 produces the same pattern of nuclear receptor localization as sc administration of the hormone. These results suggest that this inhibitory effect we previously described results primarily from a direct action of E2 on the luminal epithelium.
