By using a gel mobility assay, we have shown that treatment of HeLa cells with 4-hydroxynonenal, a major product of the peroxidation of membrane lipids and an inducer of heat-shock proteins, has the same effect as heat shock in causing the appearance of a protein which binds to the sequence of DNA specific for the induction of heat-shock genes. Lipoperoxidation and heat exposure seem to share a common mechanism of specific gene activation.
通过凝胶迁移实验,我们发现,用4-羟基壬烯醛(一种膜脂过氧化的主要产物和热休克蛋白的诱导剂)处理HeLa细胞,在促使一种与热休克基因诱导特异性DNA序列结合的蛋白质出现方面,与热休克具有相同的效果。脂质过氧化和热暴露似乎有着共同的特异性基因激活机制。
