卵清蛋白基因转录本在未受刺激的鸡输卵管中检测不到,但在类固醇激素诱导后约占输卵管细胞转录本的一半1 -3。这似乎主要是由于转录水平的增加1 -3。当类固醇激素进入靶细胞的细胞质时,它们与特定的受体结合,类固醇受体复合物在细胞核中积累4,5。据推测,这种复合物然后以序列或构象特异性的方式结合在受调控的基因附近并增强转录。最近的几项研究表明,类固醇激素受体在体外优先结合类固醇反应基因的5′-侧翼区6 -11。α2u球蛋白12、生长因子13、14、小鼠乳腺肿瘤病毒15 -19和溶菌酶20的克隆基因的转录,在转移到含有类固醇激素受体的细胞后,可在体内被类固醇激素诱导。在其中一些研究中,5′-侧翼区被证明对类固醇调节很重要。我们构建了一个含有卵清蛋白基因启动子和鸡成体β-珠蛋白基因的杂合基因,并将其转入鸡输卵管原代培养细胞。我们发现,在未转化的输卵管细胞中,孕酮介导的转录诱导依赖于位置-95和-222之间的卵清蛋白基因侧翼序列。
Ovalbumin gene transcripts are not detectable in unstimulated chick oviducts but comprise about half of oviduct cell transcripts after steroid hormone induction1–3. This seems to result mostly from an increased level of transcription1–3. When steroid hormones enter the cytoplasm of target cells they bind to specific receptors and the steroid–receptor complex accumulates in the nucleus4,5. Presumably this complex then binds in a sequenceor conformation-specific way near the regulated gene and enhances transcription. Several recent studies have shown that steroid hormone receptors bind preferentially to the 5′-flanking region of steroid-responsive genes in vitro6–11. Transcription of cloned genes for α2u globulin12, growth hormone13,14, mouse mammary tumour virus15–19 and lysozyme20 can be induced in vivo by steroid hormones after transfer to cells containing steroid hormone receptors. In some of these studies, 5′-flanking regions were shown to be important for steroid regulation. We have now constructed a hybrid gene containing the ovalbumin gene promoter fused to the chicken adult β-globin gene and transferred it into primary cultures of chicken oviduct cells. We show that progesterone-mediated induction of transcription in untransformed oviduct cells depends on an ovalbumin gene flanking sequence between positions −95 and −222.
