虽然TR 4孤儿受体(TR 4)能够通过与直接重复1-激素反应元件(DR 1-HRE)和DR 2-HRE的相互作用来抑制其靶基因的表达,但我们现在报告TR 4也可以通过氯霉素乙酰转移酶测定诱导含有DR 4-HRE的报告基因的转录活性。电泳迁移率变动分析和Scatchard分析揭示TR 4和DR 4-HRE之间的强结合亲和力(解离常数= 2nm)。TR 4介导的诱导不仅在合成的DR 4-HRE中检测到,而且在一些基因中也检测到,例如大鼠α-肌球蛋白重链和S14基因,含有DR 4或DR 4样基序,这些基因已被认为是反应元件甲状腺激素受体。我们的数据还表明,这种TR 4介导的基因诱导是TR 4剂量和DR 4序列依赖性的。总之,我们的数据表明,DR 4-HRE可以是TR 4的正调控元件,其可能能够诱导含有这种正HRE的基因的转录活性。
While the TR4 orphan receptor (TR4) is able to repress the expression of its target genes via its interaction with the direct repeat 1-hormone response element (DR1-HRE) and DR2-HRE, we now report that TR4 can also induce the transcriptional activity of the reporter gene containing a DR4-HRE via chloramphenicol acetyltransferase assay. Electrophoretic mobility shift assay and Scatchard analysis reveal a strong binding affinity (dissociation constant = 2 nm) between TR4 and DR4-HRE. The induction mediated by TR4 was detected not only in the synthetic DR4-HRE but also in some genes, such as rat α-myosin heavy-chain and S14 genes, containing the DR4 or DR4-like motif, which have been suggested to be the response elements for a thyroid hormone receptor. Our data also demonstrate this TR4-mediated gene induction is TR4 dose- and DR4 sequence-dependent. Together, our data suggest that DR4-HRE can be a positive regulatory element for TR4, which may be able to induce the transcriptional activity of the genes containing such positive HREs.
