The present invention relates to non-steroidal ligands for use in nuclear receptor-based inducible gene expression system, and a method to modulate exogenous gene expression in which an ecdysone receptor complex comprising: a DNA binding domain; a ligand binding domain; a transactivation domain; and a ligand is contacted with a DNA construct comprising: the exogenous gene and a response element; wherein the exogenous gene is under the control of the response element and binding of the DNA binding domain to the response element in the presence of the ligand results in activation or suppression of the gene.
本发明涉及非甾体配体,用于核受体基于诱导基因表达系统的使用,以及一种调节外源基因表达的方法,其中包括与DNA构建物接触的ecdysone受体复合物,该复合物包括:DNA结合域、配体结合域、转录激活域和配体;其中,外源基因位于响应元件的控制下,DNA结合域在存在配体的情况下与响应元件结合,导致基因的激活或抑制。
