ABSTRACT
The induction of the chicken ovalbumin (OVA) gene by different classes of steroid hormones and the mRNA levels of estrogen (ER), progesterone (PR), and glucocorticoid (GR) receptors were studied in chick oviducts. Combined treatment with two hormones increased the induction of the OVA gene more than single treatment, when the levels of OVA mRNA were measured with Slot blot analysis. To discover the role of nuclear steroid hormone receptors as transcriptional factors in the OVA gene induction, we analyzed the levels of ER (with RT-PCR), PR, and GR mRNAs (with Northern blotting). The level of PR mRNA was increased only by estrogen, while no steroid hormone affected the levels of ER and GR mRNAs. Thus, these findings show that the levels of nuclear receptors do not reflect the OVA mRNA level in the oviduct of steroid hormone-treated chicks.
