用雌二醇治疗未成熟雌性大鼠可增加子宫中 c-jun 和 jun-B mRNA 的水平约 10%。 10倍。这种作用是雌激素类固醇所特有的。 jun 转录物的诱导被放线菌素 D 阻断,但嘌呤霉素不被阻断,这表明激素效应至少部分归因于转录激活。激素作用迅速,治疗后 3 小时内可见 jun mRNA 的峰值水平。雌二醇在子宫中诱导 jun 和 fos 转录物表现出相似的剂量反应曲线(最大反应为 4 μg/kg)。雌二醇还可以提高子宫内 jun-D 的水平,并且这种诱导作用对嘌呤霉素不敏感。用佛波酯 TPA 进行体内治疗可迅速提高 fos、jun 和 myc 转录物的子宫水平,表明这些光癌基因的表达在该靶组织中受到非雌激素和雌激素调节。这些结果表明jun和fos原癌基因家族的多个成员可能在放大子宫对雌激素的反应中发挥作用。
Treatment of immature female rats with estradiol increases uterine levels of c-jun and jun-B mRNAs approx. 10-fold. This effect is specific for estrogenic steroids. The induction of jun transcripts is blocked by actinomycin D but not puromycin, suggesting that the hormonal effect is due at least in part to transcriptional activation. The hormone effect is rapid and peak levels of jun mRNAs are seen within 3 h after treatment. Inductions of jun and fos transcripts in the uterus by estradiol exhibit similar dose response curves (maximum responses at 4 μg/kg). Estradiol also elevates uterine levels of jun-D, and this induction is insensitive to puromycin. In vivo treatment with the phorbol ester TPA rapidly elevates uterine levels of fos, jun, and myc transcripts, indicating that expression of these photooncogenes is under non-estrogenic as well as estrogenic regulation in this target tissue. These results suggest that multiple members of the jun and fos protooncogene families may play a role in amplifying the uterine response to estrogens.
