    • A factor capable of efficiently regulating expression of an endoplasmic chaperone gene, a nucleic acid encoding it, a complementary strand nucleic acid thereof, a method for regulating expression of an endoplasmic reticulum chaperone gene, and a method for expressing a foreign gene is provided. The endoplasmic reticulum stress transcription factor is capable of regulating transcription-inducing activity, wherein the transcription-inducing activity is exhibited by an element having the nucleotide sequence shown in SEQ ID NO:1 or an element having a nucleotide sequence resulting from substitution of 1 to 3 bases with other bases in the nucleotide sequence as shown in SEQ ID NO:1. A method for controlling expression of an endoplasmic reticulum chaperone, comprising expressing the factor; a method for expressing a foreign protein, comprising positively regulating expression of an endoplasmic reticulum chaperone gene by the method for controlling expression; and a nucleic acid encoding activated form of ATF6, activated form of CREB-RP, suppressive form of ATF6, or suppressive form of CREB-RP, or the complementary strand thereto are also provided. It is expected to be applied to treatment or prophylaxis of cancers, arteriosclerosis, cystic fibrosis, ischemic diseases, wounds or ulcers.
    • 提供能够有效调节内质谱伴侣基因表达的因子,编码它的核酸,其互补链核酸,调节内质网伴侣蛋白基因表达的方法和表达外源基因的方法。 内质网应激转录因子能够调节转录诱导活性,其中转录诱导活性由具有SEQ ID NO:1所示核苷酸序列的元件或具有1〜 3碱基与核苷酸序列中的其他碱基如SEQ ID NO:1所示。 一种控制内质网伴侣蛋白表达的方法,包括表达因子; 用于表达外源蛋白质的方法,其包括通过控制表达的方法阳性调节内质网伴侣蛋白基因的表达; 并且还提供编码ATF6的活化形式,CREB-RP的活化形式,ATF6的抑制形式或CREB-RP的抑制形式或其互补链的核酸。 预期可用于治疗或预防癌症,动脉硬化,囊性纤维化,缺血性疾病,伤口或溃疡。
